Using DeltaV Operate for PROVOX® Consoles
Chapter 1
Introduction
The following figure is a schematic drawing of a DeltaV Operate for PROVOX®
Console implementation in a plant.
Figure 1-1
DeltaV Operate for PROVOX Console
Overview
The DeltaV Operate for PROVOX® Console is the combination of DeltaV and
PROVOX hardware and software that allows an operator to operate both DeltaV and
PROVOX controllers from a single PC-based operator station. Note that some of the
terminology is different between the PROVOX and DeltaV equipment and that some
special operator training may be required.
Introduction
1-1
The PROVOX components of the software have evolved from PROVOX Operator
Console software.
The console consists of a Windows-based Console Data Server connected to as many
as six DeltaV Operator Stations through Ethernet connections. The Console Data
Server is connected to the PROVOX Data Highway through a dedicated Ethernet
connection to the Highway Data Link (HDL).
The entire installation of DeltaV Operate for PROVOX Data Servers (Console Data
Servers) and DeltaV Operator Stations with DeltaV Operate for PROVOX software
installed is referred to as the DeltaV Operate for PROVOX Console.
The individual components are either DeltaV or PROVOX components. The
following list explains the major components that make up the console:
„
DeltaV Operate for PROVOX Data Server
The DeltaV Operate for PROVOX Data Server supports display of PROVOX
data on DeltaV Operator Stations.
„
PROVOX Control Network (HDLs, controllers, I/O, and so on)
This is standard PROVOX equipment. No changes or modifications are required.
„
DeltaV Operator Stations
These are standard DeltaV Operator Stations that have the DeltaV Operate for
PROVOX update installed to support display of PROVOX data.
„
DeltaV Control Network (controllers, I/O, and so on)
This is standard DeltaV equipment. No changes or modifications are required.
„
ProfessionalPLUS station
This is a standard DeltaV ProfessionalPLUS station that has the DeltaV Operate
for PROVOX update installed. ProfessionalPLUS stations are used as DeltaV
engineering workstations.
„
PROVOX Operator Console Migration Station (not shown)
This is a standard PROVOX Operator Console Operator Station at the P3.x
revision level with the DeltaV Operate for PROVOX update installed. Migration
stations are not required, but if you are migrating from a PROVOX Operator
Console, you can use migration stations to compare original displays to converted
displays to make sure they work as intended.
Note
1-2
Migration workstations are supported only for use when migrating to DeltaV Operate
for PROVOX software and are not supported for plant operation.
Using DeltaV Operate for PROVOX® Consoles
Note
In this manual the term operator station refers to both migration stations and DeltaV
Operator Stations.
As the schematic figure shows, the DeltaV Operate for PROVOX® console integrates
the operation of PROVOX and DeltaV equipment at the operator station. The two
control networks remain separate. Data does not move between the networks. (For
example, you cannot add a PROVOX parameter to the DeltaV Data Historian or view
DeltaV events in the PROVOX Event Viewer.)
Conceptually, a DeltaV Operate for PROVOX installation combines both a standard
DeltaV Operator Station running the DeltaV Operate graphics interface controlling a
DeltaV network and a PROVOX Operator Console Operator Workstation
controlling PROVOX equipment in one PC workstation.
DeltaV Operate for PROVOX software adds functionality to your DeltaV Operator
Station so that you can include links to data from PROVOX controllers in your
DeltaV displays. DeltaV Operate for PROVOX software also installs several DeltaV
Operate for PROVOX applications on the DeltaV Operator Stations that let you view
and manipulate information in your PROVOX system as if you were working from a
PROVOX Operator Console.
Experienced DeltaV users will see no difference when operating DeltaV control
equipment. Experienced PROVOX console users operating PROVOX control
equipment will see the advanced graphics capabilities provided by DeltaV Operate.
DeltaV Operate for PROVOX software does not support the graphics used in
previous PROVOX consoles, but those graphics can be converted by Emerson
Process Management for use with DeltaV Operate for PROVOX consoles.
The remainder of this manual and the other DeltaV Operate for PROVOX system
documentation use the trademarks DeltaV and PROVOX to indicate which
components are being described. The term DeltaV Operate for PROVOX Console is
used only when describing the combination and not to refer to individual
components.

Each Console Data Server can support one to six operator stations.
Operator Stations
The DeltaV Operate for PROVOX consoles use standard DeltaV Operator Stations.
The only differences are that the operator stations have an additional network
interface controller (NIC) card installed to support the connection to the Console
Data Server and they have the DeltaV Operate for PROVOX software installed.
For information on installing and setting up standard DeltaV Operator Stations, refer
to the section Installing the DeltaV Workstation in the DeltaV manual Installing your
DeltaV Automation System.
For information on setting up the additional NIC card, refer to the section Installing a
Non-DeltaV NIC in the Workstation in the DeltaV Maintenance manual.

The User Interface
Introduction
Much of the DeltaV Operate for PROVOX® software user interface is like the
DeltaV Operate user interface. This chapter does not attempt to explain the DeltaV
Operate user interface. Refer to the online manual Operator Basics and Graphics
Configuraion in the DeltaV Books Online for that information.
This chapter does explain how the DeltaV Operate user interface changes when the
DeltaV Operate for PROVOX software is installed. These differences include
changes in the alarm banner and toolbar as well as new PROVOX-related applications
that are available.
The DeltaV Operate for PROVOX user interface is shown in the following figure.
Figure 3-1

Two main pictures.
Two toolbars, one on each screen
Two alarm banners, one on each screen.
DeltaV and PROVOX integrity indicators.
Alarm Acknowledge buttons on each alarm banner.
Popup faceplate pictures.
PROVOX-related applications that are available are:
„
Instrument Area (includes the DDP area)
„
Trend Viewer
„
Event Journal
„
Summaries (Point Status and Communications Failure)
„
Document Viewer
„
Reports Viewer
The Main window combines the main graphics display, the toolbar and the alarm
banner into an integrated layout whose size and relative position are fixed. The popup
graphics display is a secondary (child) window of the Main window, but it can be
moved around the screen. The Instrument Area, Trend Viewer, Event Journal, and
summaries are separate applications that open in their own windows and that can be
moved around the screen.
User Interface Layout
The DeltaV Operate for PROVOX system must have two monitors to support the
standard interface layout.
Toolbars
The DeltaV Operate for PROVOX user interface includes two toolbars, one on each
screen. Toolbars contain buttons that provide shortcuts to menu commands and
other fields and controls. If the menu is disabled in your installation you will use the
Toolbar buttons and controls to interact with the console. The toolbars can be
configured with any combination of buttons and toolbar buttons that support DeltaV
and PROVOX systems.

Main Pictures
The two main pictures in the interface usually receive the most attention. They
contain the configured process graphics pictures.
Main pictures can include depictions of plants, a room, an area of a room, or a
physical or logical representation of some equipment. These pictures can include a
toolbar with buttons for easy navigation, such as buttons for next and previous
pictures, and the Instrument Area, Detail, or Primary Control picture for the currently
selected data link. Typically, engineers configure navigational aids to other process
graphics pictures into a picture.

Alarm Banner
This section discusses changes to the alarm banner when the DeltaV Operate for
PROVOX software is installed. For information on the standard DeltaV alarm
banner, refer to the section Alarm Banner in the DeltaV Books Online.
The DeltaV Operate for PROVOX software includes three default options for setting
up the alarm banner. All of the options include two alarm banner pictures, one for
each screen. The following sections discuss these options. Keep in mind that alarm
banners are configurable and your plant's alarm banners may be different than any of
the options.
Standard DeltaV Alarm Banner
This option provides alarming for DeltaV modules only. It does not handle alarming
for PROVOX points. In addition to the standard horn and alarm buttons, this alarm
banner contains the 10 highest-priority alarms, five on the alarm banner on screen
one and five on the alarm banner on screen two.
DeltaV Alarm Banner and PROVOX Alarm and OAR Banner
This option provides for both standard DeltaV alarming on one screen's alarm
banner and PROVOX alarm or PROVOX alarm and OAR information on the other
alarm banner.
PROVOX Alarm Banner
The PROVOX Alarm banner contains buttons that show the top five PROVOX
alarms. Each button on the PROVOX alarm banner is labeled with the tag of the
point in alarm, or the tag of the PPA the point is in if the alarm priority of the point is
less than the critical priority set in the PPA. Adjacent to each alarm button is a selector
button which, when clicked, causes the following alarm information to be displayed in
the area under the alarm buttons:
„
Date and time the alarm was received at the console
„
Point description configured in the ENVOX software
„
Alarm word configured in the ENVOX software
„
Alarm priority
PROVOX Alarm and OAR Banner
The PROVOX Alarm and OAR banner contain buttons that show both the top five
alarms and the top five Operator Action Requests (OARs).
The alarm buttons are sorted by priority within the current user’s span of control.
The User Interface
3-5
The OAR buttons are sorted by priority. Each button is labeled with the tag of the
point originating the OAR.
PROVOX Integrity Indicators
The PROVOX alarm banners include the PROVOX integrity indicators near the right
edge:
Each rectangle from left to right indicates the integrity of one of the following items:
„
Operator workstations
„
Console Data Servers
„
Highway Data Links
Green indicates all integrity is OK, yellow indicates that some equipment is not
functioning or not available but you can continue to operate, red indicates that
problems are severe enough that you cannot operate, and magenta indicates that
integrity is unknown, but that data is stale
Combined DeltaV and PROVOX Alarm Banner
This option combines DeltaV and PROVOX alarm information. The DeltaV
Operate for PROVOX Data Server (Console Data Server) must be set to use DeltaVstyle alarm processing for this option to work properly.
This option displays the 10 highest-priority alarms sorted by priority, five on screen
one and five on screen two. The alarm banner uses DeltaV alarm colors. PROVOX
faceplates, Instrument Area, and the PROVOX Alarm Summary colors use PROVOX
alarm colors.
Popup Faceplate Pictures
The DeltaV Operate for PROVOX software includes popup faceplate pictures for
PROVOX points. When an operator clicks on a PROVOX point in alarm in the alarm
banner and the point's faceplate picture appears. The following figure shows a typical
faceplate picture (for a loop point in this case).
Many of the normal point operation tasks can be performed from the popup
faceplate pictures. If you need to open the instrument area for the point, click on the
Detail button in the faceplate.

Working with Pictures
DeltaV Operate is the program that turns your computer into an operator display
station. Displays (also known as picture files) make up the contents of your display.
The commands that manipulate displays are all found on the toolbar, and are on the
menu bar, if it is enabled. This subsection describes the commands used to work with
picture files.
The User Interface
3-7
For more information refer to the section Working with Pictures in the DeltaV Books
Online.
PROVOX Instrument Area
The PROVOX Instrument area, combining point controls and a DDP area, provides
the controls you use to operate and tune points. The instrument area mimics a
faceplate in appearance, but an instrument area can include mode buttons and other
controls. The DDP area lists the DDPs available for the point. You can switch
between local and remote DDPs and hide or show selected DDPs.
The following figure shows a typical instrument area and DDP area for a loop point.
Figure 3-4
3-8
Instrument Area
Using DeltaV Operate for PROVOX® Consoles
The instrument area contains operating controls for the currently selected point. The
DDP area contains a listing of either the local or remote detail display parameters
(DDPs) for the currently selected point. The DDP area can be hidden if desired.
For more information on the controls that can appear in the instrument area, see
Operating PROVOX Points from the Instrument Area on page 3-12.
PROVOX Trend View
The PROVOX Trend View application supports real-time trending of PROVOX
process data, even when the trend application is not running or is not visible. There
are two components to trending: collecting trend data and displaying trend data.
For more information see Chapter 6.
PROVOX Viewers
There are four viewers that are a part of the DeltaV Operate for PROVOX software
that share a similar look and feel:
„
PROVOX Event Journal—displays PROVOX console and system events stored
by the message spooler. (See Chapter 7 for more information.)
„
PROVOX Status Summaries—displays PROVOX point status and
communications failure status information. (See Chapter 4 for more information)
„
Books Online—displays the online manuals for the DeltaV Operate for
PROVOX hardware and software. (See subsection Using Help and Books Online
on page 3-18 for more information.)
„
PROVOX Reports—displays PROVOX reports generated from configured
report types. (See Chapter 4 for more information)
All of these viewers rely on establishing a connection to one or more Console Data
Servers. Each viewer has a Setup button you use to create these connections.
There may be more than one way to access any of the viewers depending on whether
you are at a Console Data Server or operator station. One method that is common to
both is to use the Viewer Selector dialog. From the Start menu navigate to DeltaV
Operate for PROVOX | Viewers to open the Viewer Selector dialog as shown in the
following figure.
The User Interface
3-9
Figure 3-5
Viewer Selector
Open a viewer by clicking on its button.
PROVOX Event Journal
Instead of logging messages to a printer the DeltaV Operate for PROVOX software
saves alarm messages, Operator Action Requests, operator actions, and general
system events on the Console Data Server hard disk as comma-separated value (.csv)
files. The console software includes the Event Journal application you use to view the
.csv files. The optional database add-in to the Event Journal provides a couple of
powerful enhancements to the Event Journal:
„
A database engine that creates a database from the .csv files
„
Event Journal enhancements that provide the ability to view and query the
database in a number of ways.
For more information on using the Event Journal see Chapter 7 of this manual.
Console Startup
If you have installed the DeltaV Operate for PROVOX software as described in the
getting started manual, several services start automatically on both the Console Data
Server and DeltaV Operator Stations when they are booted.
Console Data Servers boot to the Windows login prompt and can be left as is. All the
Console Data Server services run without user intervention.
After booting the Console Data Server and its connected DeltaV Operator Stations
and before you log on to the console software the console must be downloaded. The
download must contain either user definitions for each DeltaV Operator Station or
the special user ANYNODE.
Note
3-10
Before you can log on the console must be downloaded with a configuration that defines
operator stations as users or defines the ANYNODE user. If neither of these conditions
is met, you will not have any console privileges.
Using DeltaV Operate for PROVOX® Consoles
Operator stations boot to the Windows login prompt. A user first logs on to
Windows, then uses the DeltaV FlexLock application to log on to the DeltaV
software. If you want one user name and password to log operators in to both the
DeltaV and PROVOX systems, use the same name to define each user in both the
DeltaV User Manager and the ENVOX software. In addition, you can implement
single secure logons. Refer to Section 5 of the manual Getting Started with DeltaV
Operate for PROVOX Consoles for more information.
Console Security
The DeltaV Operate for PROVOX software relies primarily on DeltaV Flexlock
security, but there are a couple of additional security considerations.
When DeltaV Operate for PROVOX software is installed on Console Data Servers
and DeltaV Operator Stations, it creates the PROVOX21 Windows user group. To
use the DeltaV Operate for PROVOX software, DeltaV users must be added to the
PROVOX21 group and their user names must be included in the ENVOX download.
Installing the software also creates a user account in the PROVOX21 group:
„
PROVOX21Admin—a user with administrator privileges
The PROVOX21Admin account has Windows Administrator privileges and is used
to start console services. The PROVOX21Admin account must have the same
password on all connected Console Data Servers, DeltaV Operator Stations, and
migration stations, if they exist. In addition, the current PROVOX21Admin account
password must be used when setting up the start options for the PROVOX POC
services on both Console Data Servers and DeltaV Operator Stations. Refer to the
Getting Started manual for more information.
Time-out Times and Update Intervals
The software has time-out times and update intervals that affect when you can input
data in the Instrument Area. These are:
The User Interface
„
Session time-out — If a software session does not detect any control activity
within the session time-out, the Instrument Area minimizes to an icon. The
session time-out is set from the PROVOX console properties dialog. From the
Start menu navigate to DeltaV Operate for PROVOX | Settings | Console
Properties. Then select the Instrument Areas tab.
„
Input time-out — If an instrument area field has input focus (is ready to accept
input) and there are no changes made within it during the input time-out time, the
field clears and you must reselect it to change the value. The input time-out time is
3-11
set from the PROVOX console properties dialog. From the Start menu navigate
to DeltaV Operate for PROVOX | Settings | Console Properties. Then select the
Instrument Areas tab.
Note that input fields configured in displays are not affected by these time-out times.
License Violations
Licensing for the console software is controlled by the License Module that plugs into
the Highway Data Link and the License.txt file installed on the console hard drive.
The License.txt file is distributed on media with the License Module. During software
installation the file is copied to the console hard disk.
The License.txt file defines the options licensed for the software: the number of
points, the number of connections, and other optional features of the software.
During startup the console software checks the license file to determine the license
profile and checks the License Module and the License.txt file to verify that they have
the same serial number. During console operation the software checks the License
Module periodically to ensure that it remains installed. If the software detects a license
violation you receive the following indications:
„
A license violation dialog box appears in the context of the Instrument Area.
„
A message is logged to the console Event Journal and Windows Event Log.
The console software continues to operate if a license violation is detected, but
displays a dialog every 30 minutes for the first 72 hours and every 10 minutes
thereafter.
If the License.txt file cannot be read when the console software starts the console
operates in one operator, 500-point mode.
Operating PROVOX Points from the Instrument Area
This subsection explains the different types of controls available in the instrument
area to operate PROVOX points. Not all point types have all controls.
Navigating
To operate a point you must first start an instrument area and load the point into the
instrument area. Depending on how you start the instrument area, a point may load
automatically.
3-12
Using DeltaV Operate for PROVOX® Consoles
If the instrument area is already running, you can change the point you are controlling
by several means. To change the point in the instrument area do one of the following:
„
Select File | Open or click the
button on the Instrument Area toolbar to
open the Tags browser. The Tags browser contains a hierarchical list of accessible
points, PMAs, PPAs, and users.

point.
„
Select a dynamic element on the graphics display.
„
Click a button in the Alarm or OAR banner to load that point's controls.
„
Click on a point tag from a summary.
Entry Fields
Entry fields provide a way for you to use the keyboard to enter a value. To prevent
accidental value changes the software requires that you follow some simple steps.
Click in the field and edit or replace the existing
value.
To overwrite an existing value with a new value, click in the field to highlight the
current value and enter the new value. The new value replaces the existing value. Press
the Enter key to transmit the value.
To edit an existing value, click once to highlight the entire value then click again to
position the cursor. Edit the value as required. Press the Enter key to transmit the
value.
The value is sent to the instrument. You will not receive any feedback unless the
console has a problem sending the value.
The User Interface
3-13
Slew buttons
Slew buttons (also known as spin buttons) provide a way to change a value gradually.
To use slew buttons:
Open slew buttons by clicking when the
cursor turns to a hand.
The slew buttons and an input field appear.
You can enter a value directly in the input
field and press Return to transmit the value.
The point accepts the new value or displays
an error message.
or
Slew the value using one of the buttons. As
you slew the value in the input field
changes. If you hold the button for several
seconds, the rate of change increases. Value
changes you make using the slew buttons
are transmitted automatically. You do not
need to press Return to transmit the
changes.
There are a couple of other things to be aware of about slew buttons. Each time you
click and release on a slew button a value is transmitted.
If you click and hold a slew button, the value in the input field changes several times
per second. The value initially changes by approximately 0.1 percent of its range per
update. After you hold the button for a few seconds the rate of change increases to
approximately 1 percent of its range per update. If you are holding a slew button,
values are not transmitted every update, but periodically transmits the value currently
in the input field to avoid overloading the field device.
3-14
Using DeltaV Operate for PROVOX® Consoles
Mode Buttons
Use the mode buttons to set the operating mode of a point:
Click on the Mode field when the cursor
becomes a hand.
Click on one of the two buttons or click
the
button to open a list of modes
available. The two buttons will usually be
MAN and AUTO, but for some points
will be MAN and CMPTR. The dropdown list is available only if there are
more than two modes available for the
point.
Select a mode by clicking on it.
The mode buttons have the following effect:
„
Manual — Sets the point to the control mode in which you can:
•
•
•
•
Change the valve output of a Loop Point or Analog Output.
Change the setpoint of a DCD or Discrete Output.
Start or stop an LCP.
Disable a group or unit point thereby putting the items belonging to the
group or unit into the manual operating mode.
Points in Manual mode generally reject changes by anything other than an
operator.
„
The User Interface
Auto — (Automatic) Sets the operating mode to automatic. For loop and group
points you can change the setpoint. The control algorithm then attempts to
achieve the setpoint value.
3-15
For unit points set to Auto you can load an operation but activities and higherlevel programs cannot load operations.
Other points in Auto mode reject output commands from operators.
„
RSP — (Remote Set Point) Sets the loop to the control mode in which the
setpoint value comes from outside the control loop, typically from the output of
another control loop. For a DCD point, the setpoint tracks changes made
remotely.
Points in RSP mode generally reject SP changes from operators or LCPs.
„
SUPV — (Supervisory) Sets the loop to the control mode in which a process
computer, a computer program, a unit point, or a logic control point supplies the
setpoint value.
Points in SUP mode reject operator or other loop SP inputs.
„
DDC — (Direct digital control) Sets the loop to the control mode in which the
process control computer or a computer program, a unit point, or a logic control
point directly sets the output of a control loop.
Points in DDC mode reject operator output changes.
„
Computer — Sets most points to the control mode in which another point or a
computer program controls the input and output.
Points in Computer mode reject output commands from operators. Most loop
points do not have a computer mode, though CHIP loop points may.
Bar Graphs
Though not a control, the bar graphs in the instrument area for analog points provide
useful operating information.
3-16
Using DeltaV Operate for PROVOX® Consoles
Analog points have bar graphs that show the VO, PV and SP
values. The bars are color coded to match the entry fields.
The High and Low Engineering Units values appear at the
top and bottom of the bar graphs.
Toggle Buttons
Toggle buttons are used on points that have parameters that have two discrete values.
Discrete Output points, for example. To use toggle buttons:
Click in the value area when the cursor
becomes a hand.
The toggle buttons appear. Click on
the desired value. The new value is
transmitted to the field device.
Drop-Down Lists
Drop-down lists are used on points that have parameters that can have several
discrete values. Group points, for example. To use drop-down lists:
The User Interface
3-17
Click in the area of the value to change.
A drop-down list appears. Select the desired
new value by clicking. The new value is
transmitted to the field device and the menu
closes. To close the menu without selecting a
value, click the X in the upper right corner of
the menu.
Using Help and Books Online
The console software includes online help for each application, and a set of online
books. The online help generally answers immediate questions about an application.
The online books provide background and theoretical information.
Online Help
The software Help menu that is in most applications provides a number of selections.
Access any of the help menu selections by using the mouse or by pressing the key
corresponding to the underlined letter on the selection. Some dialogs contain a Help
button, either in addition to or instead of the Help menu. Click the Help button to see
help on the current dialog. The operator interface toolbar and alarm banner contain a
question mark button. Press the button to open a window that contains help
information.

Console Operations
Introduction
This chapter explains how to use the console software to monitor and control a
process.
Accessing Information
To control a process effectively, you must be able to access information relevant to
your assigned area of responsibility. The most commonly used methods of access are
through displays, alarm lists, and summaries.
Without some method of providing selective or directed access to displays and alarms,
you would quickly become overloaded with information that is not relevant to your
assignment. Console configuration provides the method by which you are directed to
relevant displays and alarms.
To acknowledge an alarm and change point values, you must:
„
Be on the password access list
„
Have the correct privilege level
Using your password and the privilege level assigned to it, you can access the displays
and alarms necessary to control your portion of the process.
Password Security
The configuration restricts access to many functions to those who have the proper
authority as identified through a password. To log on to the Operator Interface, you
must enter a valid user name and password that were configured in the ENVOX®
software and downloaded to the console. The software session opens with the
privilege level associated with your user name.
Console Operations
4-1
Privilege Level
Your password will be associated with one of the following privilege levels:
„
DOWNLOAD — Includes the ability to download to the console and access the
utility functions. Excludes the ability to access displays, and operating and tuning
data.
„
LOCK — Includes access to help and utility functions. Excludes the ability to
access displays and operating and tuning data.
„
ACCESS — Includes all of the capabilities of LOCK and permits viewing
information on displays. Excludes the ability to change operating and tuning data.
„
OPERATE — Includes all of the capabilities of ACCESS and permits changing
operating data and executing utility procedures. Excludes the ability to change
tuning data.
„
TUNE — Provides all of the capabilities of OPERATE and permits changing
point tuning data.
Depending on your responsibilities, your operator session account can also be
assigned one or both of the following during configuration:
„
PPA CHANGE — Provides the ability to change plant process area (PPA) states
and critical levels.
„
PMA CHANGE — Provides the ability to change plant management area
(PMA) modes.
Refer to the subsections Plant Process Areas (PPAs) on page 8-5 and Plant
Management Areas (PMAs) on page 8-9 for more information. Refer to Appendix A
for more information on the privilege level required to use a function.
Console Integrity
If you believe the console is not functioning properly, the first thing to check is the
three integrity indicators near the right edge of the Alarm (or Alarm and OAR)
banner.
The leftmost indicator reports the integrity of the operator station, the center
indicator reports the combined integrity for the active (and standby, if defined)
Console Data Servers, and the rightmost indicator reports HDL integrity.
Because an operator station can connect to two Console Data Servers (and two
HDLs), the Console Data Server indicator and the HDL indicator report combined

is if both the active and standby Console Data Servers (or HDLs) have good integrity.
To open detailed integrity information for the console and its components, click the
indicators or the Integrity button on the toolbar. To interpret the integrity
information consult with your Emerson Process Management service representative.
Display Access
There are two types of displays: main and popup. There are several ways you can
access main displays:
„
From the Display History

Alarm Colors
Alarm colors, foreground (text) and background are specified during configuration.
However, the foreground and background color of alarm indicators may not appear
as configured. In addition, alarm colors may depend on where the indicators appear:
„
„
Faceplates in displays, the alarm banner, and the alarm summary, support only
colors 0 through 15. Alarms that use either foreground or background colors
with an index greater than 15 are set to Yellow Blink foreground and Red
background.
The Instrument Area supports the full set of PROVUE® alarm colors except that
the gray color is mapped to a salmon pink. The alarm gray does not provide
enough contrast against the gray background the console uses.
If you use the combined DeltaV and PROVOX alarm banner with DeltaV-style alarm
processing, the alarm banner uses DeltaV alarm colors. PROVOX faceplates, the
Instrument Area, and the PROVOX alarm summary all continue to use PROVOX
alarm colors.
Viewing Faceplate Displays
Faceplates provide detailed information about points. You can view faceplate displays
created during configuration. Faceplate displays created during configuration
generally have full-size faceplates for 12 related points.
Alarm Access from Displays
The configuration engineer may designate an alarm display for each point in the
system. An alarm display typically provides all you need to see the reason for the alarm
condition. You will see only the alarms in the plant management areas (PMAs) and
plant process areas (PPAs) you have the permission to operate.
To correct an alarm condition, you must operate the point, either in the instrument
area or on displays that have been configured to operate points. There are several ways
to get the controls for a point in alarm into the instrument area:
„
Click on one of the buttons in the alarm area representing the five highest priority
alarms
„
Click on a dynamic element in the main display
„
Through PPAs and PMAs
„
From the Alarm Summary
As many as 250 of the current alarms appear in the alarm summary.
4-4
Using DeltaV Operate for PROVOX® Consoles
After you access the display for the point in alarm, select the point and acknowledge
the alarm for the point. Alarms are displayed in the lower right corner of faceplates
and the lower left corner of instrument areas.
To acknowledge alarms, click on the
(Ack Alarm) button in the alarm banner.
Depending on your configuration, clicking on the button does one of the following:
„
Acknowledges all unacknowledged alarms in the current display
„
Acknowledges the alarms for the selected point only
Click on the
(Silence Horn) button in the DeltaV alarm banner to silence the
console horn caused by a new, active alarm. You can acknowledge the horn regardless
of the current display. This acknowledges the horn on its own station or on all
stations, as determined by the console configuration.
If you configure Ack All Station Horns to NO in the ENVOX software, you should
also enable Global Horn Acknowledgment in the DeltaV workstations. If you do not
synchronize these settings acknowledging the horn does not work as expected.
Note that the ack horn button on the PROVOX Instrument area does not silence the
horn.
Viewing Summaries
Summaries are lists of information available in an operator session. Summaries
provide specific types of information from the console database. You can access a
point from any summary that contains points by clicking on the point tag in the
summary window.
Buttons on the toolbar provide a way to view the following:

The alarm summary displays current alarms (active and inactive but unacknowledged)
for each point. Memory constraints limit the number of entries in the summary to
250. If there are more than 250 points the software displays the following message in
the upper right corner of the summary, under the page number:
More than 250 Alarms
The alarm information on the summary is updated dynamically.
The configuration engineer determines how the console organizes the points that are
in alarm, and alarms for the same point, either oldest to newest or newest to oldest.
You can use the Priority and Time toggles to set how the alarms are listed.
The alarm summary sorted by time shows all alarms. The alarm summary by time

Diagnostic Information
A couple of different types of diagnostic information are available from the console:
„
Console integrity information, including Resync (Device Programming)
information
„
Point Status and Communications Failure information
Console Integrity Information
The console integrity information is implemented on several faceplates and is
accessible by clicking the integrity icon on the main window or the integrity indicators
in the alarm banner.
As you operate be aware of the three indicators in the bottom right corner of the
PROVOX® Alarm Banner. If any of these indicators is any color except green, that
indicates a potential problem.
Console Operations
4-7
The color of the indicators on the Alarm banner and the integrity faceplates reflect
the integrity of one or more pieces of hardware:
„
Red — The integrity of the hardware this indicator represents is bad. You cannot
operate the process.
„
Yellow — You can operate the process but the integrity of the hardware this
indicator represents is questionable.
„
Green — The console is operating normally and the integrity of the hardware
this indicator represents is good.
„
Magenta — The data displayed is stale. The integrity of the hardware this
indicator represents is unknown.
„
No color or hidden — This indicator does not represent any hardware because
the hardware is not configured.
Resync (Device Programming) Information
The device programming summary is accessible from the Integrity display. The
Resync display is a history of as many as the last 10 device resyncs and as many as the
last 10 devices resynced. This aids in understanding the cause of the resyncs. The
device programming summary contains the following information for each device
resync listed:
„
The device address for the device that was resynced
„
The date on which the device resync occurred
„
The time at which the device resync occurred

Console Redundancy
Redundancy in process control means that more than one hardware or software
component is capable of performing important control functions. There are two
different types of console redundancy implemented in the DeltaV Operate for
PROVOX Console:
„
4-14
Console Data Server redundancy — Operator stations can connect to two
Console Data Servers, Primary and Secondary, one of which is Active and the
Using DeltaV Operate for PROVOX® Consoles
other is Standby. During normal operation the workstation receives process data
from the Active Server. If the Active server fails the workstation can switch to the
Standby server.
The Primary and Secondary Console Data Servers are defined during software
setup from the DeltaV Operate for PROVOX properties dialog.
„
Console-resident point redundancy — Point processing for console-resident
points that support point redundancy can be done in two paired Console Data
Servers, a Primary and a Secondary. One of these is Active, reporting point
information to the operator stations, the standby server, and other devices. The
other server is Standby. It is receiving point updates from the active controller. If
the Active server fails, the Standby Console Data Server detects the failure and
takes over reporting point information.
The Primary and Secondary Console Data Servers are defined during console
configuration and can be redefined only through a total download.
Console Data Server Redundancy
Console Data Server redundancy is defined from the perspective of the operator
station. Each workstation can receive data from either of two Console Data Servers.
Console Data Server redundancy is defined in the Console Properties dialog of each
workstation by indicating a primary Console Data Server and secondary server for each
workstation.
The workstation attempts to establish communication with both the primary and
secondary Console Data Server when the workstation services start.
For more information on Console Data Server Redundancy, refer to the manual
Getting Started with DeltaV Operate for PROVOX Consoles.
Redundancy Event Logging
Changes in Console Data Server redundancy are logged when:
„
The workstation switches over to the standby server.
„
The automatic switchover function is enabled or disabled.
Manual and Automatic Switchovers
Switchovers can be performed automatically or manually. An operator must have
OPERATE or TUNE privilege to perform manual switchovers or disable automatic
Console Operations
4-15
switchovers. To enable automatic switchovers operators must have ACCESS,
OPERATE, or TUNE privilege.
Caution
Emerson Process Management recommends that you attempt manual
switchovers only if the standby Console Data Server status is Ready.
Because the workstation allows a manual switchover even if the status of the
standby server is Unknown, you may lose data if you attempt a switchover
when the standby server is unavailable. You must ensure that the standby
server is available to become active before requesting a manual switchover.
You can switch a workstation to its redundant server manually from the workstation's
integrity faceplate. To navigate to the Console Data Server Redundancy faceplate click
on the PROVOX Diagnostics button in the toolbar or the PROVOX Integrity
buttons in the PROVOX alarm banner. Click the Data Server field in the integrity
faceplate and the POC Integrity Detail picture including Console Data Server
Redundancy controls appears as shown.
4-16
Using DeltaV Operate for PROVOX® Consoles
Figure 4-7
Console Data Server Integrity Display
You can perform a manual switchover when the standby server is Ready, Unknown,
or Idle (not downloaded). Automatic switchovers occur when the active Console Data
Server has a critical failure, such as a power loss. When either a manual or automatic
switchover occurs, the workstation then disables the automatic switchover function.
When the primary Console Data Server is available again you can re-enable automatic
switchover and manually switch back to the primary server.
Console-Resident Point Redundancy
Console-resident point redundancy, also known as console point redundancy, is
defined from the perspective of a pair of consoles in the same PROVOX area.
Console point redundancy provides for continued operation of console-resident
points (that support redundancy) if a console fails or becomes unavailable.
Console Operations
4-17
The redundant pairs of consoles are configured and cannot be changed except
through a download.
There are five console-resident point types that support redundancy:
„
Activity points
„
Discrete control device points (DCDs)
„
Extended pulse count input points (EPCIs)
„
Integrity points
„
Accumulation points.
The two other console-resident point types do not support redundancy: maintenance
and single-bit discrete points.
During configuration, one console of the redundant pair is configured as the primary
console and the other is configured as the secondary console. The currently active
console performs point processing for console-resident points and reports the
information to the Standby Server, operator stations, and other devices.
Console point processing can switch from the currently active server to the standby
server either through operator action or automatically, if auto switchover (of consoleresident point redundancy) is enabled.
For more information on Console-Resident Point Redundancy, refer to the manual
Getting Started with DeltaV Operate for PROVOX Consoles.
Console Pairing for Console Point Redundancy
A primary console is the master in the redundant pair’s communications. It becomes
active following any disagreement about which console of the pair should be active.
A secondary console is the slave in the redundant pair. It becomes the standby
console following any disagreement about which console should be active. The
standby console tracks the active console, so that if the active console fails, the
standby console accepts control of the process (becomes the active console).
In redundant pairs, if the active console fails, the standby console becomes active and
resumes operation. By configuring the point this way, it remains operable even if one
of the consoles fails.
However, if a console-resident point is in a simplex console and targeted to other
consoles, you can operate the point from any of the other consoles as long as the
point’s source console is operating. If the console where the point is resident fails,
though, the other consoles show UNAVL (unavailable) for the point, and it is no
longer available for operation.
4-18
Using DeltaV Operate for PROVOX® Consoles
Manual and Automatic Switchovers
Switchovers can be performed automatically or manually. An operator must have
OPERATE or TUNE privilege to perform manual switchovers or disable automatic
switchovers. To enable automatic switchovers operators must have ACCESS,
OPERATE, or TUNE privilege.
Caution
Emerson Process Management recommends that you attempt manual
switchovers only if the standby Console Data Server status is Ready.
Because the workstation allows a manual switchover even if the status of the
standby server is Unknown, you may lose data if you attempt a switchover
when the standby server is unavailable. You must ensure that the standby
You can switch console-resident points to their redundant server manually from the
workstation's integrity faceplate. To navigate to the Console Data Server Redundancy
faceplate click on the PROVOX Diagnostics button in the toolbar or the PROVOX
Integrity buttons in the PROVOX alarm banner. Click the Console Point Redundancy
field in the integrity faceplate and the POC Integrity Detail picture including ConsoleResident Point Redundancy controls appears as shown.
Console Operations
4-19
Figure 4-8
Point Integrity Detail
Colors in the Redundancy part of the display have the same meaning as for Console
Data Server redundancy.
Effects of Console-resident Points
Console redundancy rejects a manual switchover request while the points are not
synchronized and the console can communicate with its partner. Disallowing manual
switchovers prevents unnecessary failures caused by switchovers while consoleresident points are not synchronized.
Normally, console-resident points are ready for manual switchover within three
minutes of establishing communications after download.
Redundant Pair Downloading
If you are doing a partial download configuration update on a standby console, the
configuration update has no effect on any console that obtains data from the pair. If,
however, you do a partial download on an active console, either as part of a redundant
4-20
Using DeltaV Operate for PROVOX® Consoles
pair or as a simplex console, other devices that get point information from that
console display an unavailable status until the configuration update ends. Follow the
procedures for total and partial downloads outlined in the documentation for the
configuration software you are using.

Operating and Tuning Points
Introduction
You use the console software to manage data and control the process by operating
and tuning points. The console software provides a window into the process, but has
no direct link or connection to the process. Access to the process is provided by a
controller that communicates with the console.
The point types available in PROVOX® systems offer a broad range of control and
monitoring functions. The configuration engineer uses these point functions to define
an interface you use to control the process and manage alarms. The configuration
engineer targets points to one or more consoles. The controller updates the console
with the latest information from the process.
Operating a point consists of changing operating parameters that typically need to be
changed frequently during normal plant operations—a loop setpoint, for example.
You use the console to change outputs that are sent to the controller and on to the
process. Higher level points, such as loop points, provide automatic output changes to
the process with updates to the console. The configuration engineer defines alarms to
alert you to abnormal conditions.
Simple input points may provide information and alarms only, while a complex loop
point can provide automatic control of a process variable such as level, flow, pressure,
or temperature. An LCP (Logic Control Point) can provide interlocking or sequencing
capability, while a Unit point can run repeated batches of a product. These and other
points provide you with information and control capability.
Tuning a point consists of changing tuning parameters that typically do not need to be
changed as often as operating parameters. For example, if the grade of raw material
available for a process changes, loop gains may have to be changed to compensate.
Point tuning requires TUNE privilege.
Some points originate in controllers and some originate in consoles. The following
points originate in consoles because they do not need direct access to the process:
„
Console single-bit discrete point
„
Console discrete control device (DCD) point (used with discrete points from a
controller that does not support DCD points)
Operating and Tuning Points
5-1
„
Console extended pulse count input (EPCI) point (used with PCI points from a
controller that does not support EPCI points)
„
Accumulation point
„
Maintenance point
„
Integrity point
„
Activity point (with batch software only)
This section describes some of the PROVOX points and how to operate and tune
them.
Point Modes
The mode of a point determines what the point is able to do, and who or what is
expected to exercise control of the point’s attributes, such as setpoint and output.
Only output points, such as discrete output (DO), analog output (AO), Loop, discrete
control device (DCD), logic control points (LCP), and so on, can have modes.
Note
Input points do not have a mode because they provide process and alarm information but
do not provide direct control over any output values.
The following list shows the modes points sourced in SR90 and later controllers can
have and the common abbreviations for the modes:
„
Manual — MAN
„
Automatic — AUT or AUTO
„
Remote setpoint — RSP
„
Supervisory — SUP
„
Direct digital control — DDC
„
Computer — COM or CMPTR
Not all modes are available on all points.
5-2
Using DeltaV Operate for PROVOX® Consoles
Allowable Modes
No point uses all of the modes. Some modes are available only if they have been
configured, for example, loop points can be configured for RSP, SUP, AUTO, and
DDC modes. The following table lists the possible modes for common point types.

operators but does not accept commands from a higher level point such as an LCP or
Unit point. A DO point in COM (computer) mode does not accept operator
commands, but does accept commands from an LCP or Unit point. No other modes
are available for a DO point.

A point’s mode may also affect the function the point is able to perform. For example,
a basic loop point in the AUTO mode controls the output based on a setpoint you or
another operator specifies. You cannot control the output directly from the console.
In MAN mode you directly control the output of the loop and the setpoint is ignored.
The availability of some modes is limited by the point’s configuration. For example,
the RSP (remote setpoint) mode is available for a loop point used in a cascade

Using DeltaV Operate for PROVOX® Consoles
application, but not for a routine loop. Further, a loop point can never be set to COM
mode.
The mode of a point can be changed by an operator, another point, or by a CHIP
program. When the mode of a Group or Unit point is changed, the modes of the
points it controls may also change. Refer to the descriptions of the individual point
types for more information on the modes that are valid for each point type and how
they affect the point.
Privileges and Access Levels
As part of the way security is implemented in the DeltaV Operate for PROVOX
Console, operator stations are considered users and must be defined as such. Your
access to the process is determined both by your configured privilege level and the
configured privilege level of the operator station you are using.
The recommended procedure is to configure each operator station that is a dedicated
operator station as a user in the ENVOX® software. These users should have access
consistent with the requirements of each console and the plant's security policy.
To allow access to other users who log on from workstations that are not dedicated
operator stations—managers and engineers, for example—the special user
ANYNODE can be configured in the ENVOX software. The ANYNODE user sets
the privilege for any operator station that is not explicitly configured as a user.
Note
If operator stations are not configured as users or the ANYNODE user is not
configured, users who log on to the console software will not have any privileges and will
be unable to do anything, including closing and exiting the software.
The operator station and ANYNODE users should have their own unique
passwords. (Users who know the password to one of the operator station users can
log on to any operator station as that user.)
An operator's access to the process is the most restrictive of the operator's configured
privilege and the operator station's configured privilege. For example, operator Sam
with a base privilege of OPERATE is logged on to the operator station CONSOLE2.
CONSOLE2 is configured as a user with TUNE privilege. However, operator Sam
has only OPERATE privilege so he cannot tune any points.
Engineer Joe, whose base privilege is TUNE, needs to tune a point. He logs on to
CONSOLE2. Because both Joe and CONSOLE2 have TUNE privilege, Joe can tune
the point.
Operating and Tuning Points
5-5
The plant also has a operator station named DEMO1 that is not configured as a user.
The ANYNODE user has been configured with OPERATE privilege, however, so
that privilege applies to DEMO1. If engineer Joe had logged onto DEMO1, he would
not be able to tune the point as his TUNE privilege would not be able to overcome
the more restricted access of the ANYNODE user definition.
The plant could use the access privileges in the following manner: A new operator
might have ACCESS privilege to allow him to become familiar with the console.
ACCESS privilege does not allow alarm access or the ability to control points.
An experienced operator could take over the terminal and log on with OPERATE
privilege. This operator could control assigned plant areas and receive alarms that
related to those areas.
An engineer could then take over the terminal and log on with TUNE privilege. When
tuning was complete, the engineer could turn the terminal back to the experienced
operator who would log on again with OPERATE privilege.
Point Status
The status of a point affects what you can do to a point and what the point can do, so
it is important to know the status of a point you are attempting to operate or tune.
Point status information appears in a number of places:
„
Instrument Area
As many as four status messages can appear in the bottom right of the instrument
area. If there are no status messages, the area appears blank. Most status messages
are yellow text on a black background, but OARP (OAR Pending) messages are
yellow text on a red background.
„
Display (with faceplates)
Your configuration may have displays that include faceplates of points of interest.
In the faceplates on the displays, status messages are at the lower left. If there are
no messages, the area appears blank. Faceplates can display one status message.
„
Display (with status block)
Your configuration may have displays that include status blocks. The status blocks
can be configured to contain any number of status words. A status block that is
eight words high and one word wide can contain all reported status messages.
In general, point status has no effect on tuning, but changing some tuning parameters
can result in status messages being displayed. If a point with one or more inputs is
5-6
Using DeltaV Operate for PROVOX® Consoles
tuned off scan, the status message ROFS appears. If a point with one or more outputs
is tuned out of service, the status message RIOS appears.
The following table lists and explains the point status words that can appear. Not all
status words can appear for all points.

Operating Points
Operating a point consists of changing point parameters that need to be changed
relatively frequently while a process is running, for example, a loop setpoint. The
software provides a powerful and flexible interface for operating points.
This subsection provides general guidelines for operating most point types and
specific operating instructions for several point types with unique operating
requirements. Each point type supports only certain parameter changes. Appendix B
lists most point types and the valid parameter changes for each.
When you operate a point you:

„
Select the point (open it in the instrument area)
„
Change a parameter value
Using DeltaV Operate for PROVOX® Consoles
Selecting a Point
There are several ways to select a point to operate:
„
Click on an alarm button on the main window
„
From an Alarm or OAR summary, select a point
„
Click on a dynamic field in the graphics display
„
Click on an OAR button
„
Use the tag browser in the Instrument Area
Selecting and Changing a Point Parameter
After you have selected a point to operate, its controls appear in the instrument area.
If the console configuration specifies Auto Parameter Select, the console
automatically gives input focus to the appropriate control when you select a point.
The parameter the console selects depends on the point’s current mode. Appendix C
lists the automatically selected parameters for various point type and mode
combinations.
For example, if you select a loop and the point’s current mode is AUTO, the console
automatically puts input focus on the setpoint entry field. Input-only point types such
as analog input (AI) and discrete input (DI) and option button and one of n controls
do not support automatic parameter selection.
After you attempt to change a parameter value, the software either accepts the change
and updates the point controls and faceplate (if visible) or a message appears in a
popup dialog box. For example:
The first line explains why the instrument area did not accept the change. The second
line contains the point tag, the configured description, and the parameter you
attempted to change.

Discrete Points
This subsection describes how to operate the following point types:
„
Single-bit and four-bit discrete input points (DI)
„
Single-bit and four-bit discrete output points (DO)
„
Controller Discrete Control Device points (DCD)
„
Console-resident DCD points
„
Enhanced SR90-Series and later controller DCD points
„
Controller Group Points
A DI or DO point that originates in a controller such as an SR90 is a single-bit point.
MUX, PCIU, and DCU devices all have four-bit points. In addition to the four-bit
point, as many as four single-bit points can be configured for the four-bit point to
simplify the operator interface and to allow different bits to report to different PPAs.
Discrete Control Device (DCD) points provide advanced control to simplify your
interaction with the process. DCD points can be configured to either monitor or
control a process consisting of multiple discrete inputs and outputs.
A console-resident DCD is available to interact with four-bit points that originate in
MUX, PCIU, or DCU devices, because these devices cannot support DCD points
themselves.
Enhanced DCD points originate in SR90 revision P4.0 and later controllers. These
points provide advanced interlocking and sequencing capability.
Group points provide supervisory control to as many as eight subordinate DCD
points. Without the group, you would have to manipulate each DCD individually. The
Group point accepts operator commands and controls the associated DCD points.
Single-Bit and Four-Bit Discrete Input Points
The following figure shows the instrument area for a single-bit discrete input (DI)
point. The instrument area for a four-bit discrete input point is similar, but has four
sets of toggle buttons. The controls for a DI point are toggle buttons that appear
when you click on the current value. The instrument area includes the current value
for CNTCT1 and point alarm and status information.

Input points have no mode and cannot be operated. The contact toggle that appear
when you click on the current value seem to invite an input:

However, the buttons can be toggled only if the point has been tuned off scan. A
status message appears in the instrument area that indicates the point is off scan.
After tuning the point off scan, select the desired contact by clicking on the desired
toggle button. Only one pair of toggle buttons appears on a single-bit point.
Single-Bit Discrete Output Points
You can change the CNTCT1 value for a single-bit discrete output point in manual
mode. The following figure shows the instrument area for a single-bit discrete output
point.

To change the point's value, click on the current value and toggle buttons appear:
Note
Some single-bit discrete points are derived from four-bit discrete points. If you change the
attribute of a derived single-bit discrete point, the attribute of the four-bit discrete point
from which it was derived changes also.
Four-Bit Discrete Output Points
The following figure shows the instrument area for a four-bit discrete output point.
Change the contact values by clicking on a value. Two toggle buttons corresponding
to the available values for that contact appear.

Controller Discrete Control Device (DCD) Points
Pre P4.0 controller Discrete Control Device (DCD) points control field devices that
have discrete states, such as pumps (on and off) and solenoid valves (open and close).
These devices can have as many as 16 discrete inputs and as many as eight discrete
outputs using as many as 16 named setpoint defined in a DCD template. You can use
a DCD point to select desired setpoints or to monitor discrete inputs.
5-14
Using DeltaV Operate for PROVOX® Consoles
Each setpoint name represents a different operational state for a discrete device by
determining a useful combination of values (0s and 1s) for the discrete output values.
By selecting a single DCD setpoint value, you change multiple discrete output values.
Furthermore, the DCD point continually monitors the status of the discrete inputs
and selects the process variable (PV) that matches the inputs. If the PV does not
match the setpoint after a configured amount of time and number of retires, the DCD
fails. An alarm word appears in the instrument area to indicate the failure.
Mode, setpoint, and process variable are the valid parameter selections for DCD
points. Process variable changes are accepted only if the point has been tuned off
scan.
The following figure shows an instrument area for a typical DCD point.

Enhanced Controller DCD Points
Enhanced DCDs are available in SR90 revision P4.0 and later controllers. Enhanced
DCDs have all the functionality of DCDs plus the ability to have as many as eight
conditions affect the point’s operation.
The controller can be configured so that enhanced DCDs either prevent or make
changes to a setpoint automatically when a specified condition occurs.
After the conditions have been defined for a DCD, the configuration engineer creates
a table for the appropriate setpoints and conditions, similar to the following table.
Each entry specifies a setpoint name, the conditions which apply to that setpoint, and
the failure processing options for that setpoint entry when specified conditions are
TRUE (tripped).

Enhanced DCDs allow additional control features such as interlocking, permissives,
and sequencing:
„
Interlocking prevents an action under certain conditions for safety and other
reasons.
„
Permissives are constraints similar to interlocks that also prevent a setpoint
change if certain condition exists.
„
Sequencing is limited to 16 setpoints and 8 conditions and allows automatic
changing to a different setpoint as a result of a configured condition that occurs.
The following figure shows the instrument area for an enhanced DCD.

The items that can appear in an enhanced DCD instrument area include:
„
Configured condition names appear in the eight lines immediately below the
parameter fields. A line indicates that the corresponding condition is not
configured. The condition names present three types of status information:
•
•
•
Condition status is represented by the color of the condition name. If the
configured condition name appears in red the corresponding status is true. If
the configured condition name appears in blue the corresponding status is
false.
Ignore status is represented by the background color of the condition. If a
condition is ignored, its background color is Yellow.
First Fail status is represented by the background color of the condition. If
a condition is the first failed condition, its background color is White. The
index number of the first failed condition is reported in the FRSTFAIL
display attribute.
In the default faceplate for Enhanced DCD points condition statuses are
presented similarly. The faceplate contains a CS: (condition status) field
consisting of eight characters that indicate the status of the eight conditions
configured for the DCD:
•
•
•
A dash (-) indicates that the corresponding condition is not configured or that
the DCD is not reporting as enhanced
A red A indicates that the condition is ACTIVE or TRUE
A blue I indicates that the condition is INACTIVE or FALSE
For example, the faceplate for the point shown in the figure includes the
following:
The As in the first, third, sixth, and eighth position indicate active conditions.
The Is in the second and seventh position indicate inactive conditions. The
dashes in positions four and five indicate that these conditions are not
configured. The A on the white background in position three indicates the first
failure condition.
To summarize, the following table shows the possible color combinations for the
configured enhanced DCD interlock conditions.

Note that if an Enhanced DCD appears in a regular DCD faceplate no condition

that the word Enhanced appears in the faceplate.
„
The next three fields can contain indicators:
•
„
„
IGNORE ALL indicates all active conditions are ignored. This field is
displayed in yellow if all conditions are being ignored. This field is blank if all
conditions are not being ignored.
• MODE LOCKED indicates that the mode of the DCD cannot be changed
from any source. This item is displayed in the color cyan (light blue) if the
mode is locked. This item is blank if the mode is not locked.
• SP PENDING indicates that the DCD has a setpoint pending. A pending
setpoint can occur if the DCD has a TRUE condition that caused the DCD
to fail and the action associated with the condition is configured with Drive on
Clear set YES. SP PENDING appears in cyan (light blue) if a setpoint is
pending. This field is blank if a setpoint is not pending.
The MODE field indicates the current mode of the DCD (CMPTR, MAN, or
RSP).
The ALARM Block indicates the current alarms for the DCD point. If the field is
blank, no abnormal conditions exist. When a setpoint or requested setpoint
change does not or should not occur, an interlocking process causes the DCD
point to fail. This failure is indicated by one of three words that appears in the
DCD alarm block. Each alarm word is associated with a particular alarm:
•
PFAIL (Alarm A) — A Permissive Fail state occurs if you select a setpoint
and a condition is true and the configured DCD action is PERMISSIVE. The
setpoint changes, but outputs are not driven.
For example, if a valve downstream from a pump is closed (the condition is
VALVE CLOSED LIMIT SWITCH = TRUE) and you select the START
setpoint for the pump, the setpoint changes to START, but permission is not
granted to start the pump so no output is sent to the pump. The setpoint
5-20
Using DeltaV Operate for PROVOX® Consoles
indicates START, the process variable indicates STOP, and PFAIL appears in
the alarm block and instrument area of the DCD faceplate.
•
IFAIL (Alarm B) — An Interlock Fail state occurs when a condition is true
and the associated DCD action is DRIVE OUTPUTS.
For example, if a motor is running (the setpoint is START) and an interlock
condition occurs that requires the motor be turned off, the output is driven
to off (the process variable is STOP). The status word IFAIL appears on the
DCD faceplate and instrument area.
•
FAIL (Alarm C) — A Fail state occurs if a field device fails.
For example, a motor is running (setpoint = START and process variable =
START) and then loses power. The process variable changes to STOP and
FAIL appears in the alarm block on the DCD faceplate and instrument area.
„
The STATUS block indicates if the enhanced DCD point was configured to
disable (ignore) setpoints under certain conditions during operations. The
controller notifies the console that a setpoint is disabled in the unsolicited data
packet for that point. If the point is selected while a setpoint is disabled, the
setpoint on the menu button is faded or stippled and the setpoint cannot be
selected or transmitted.
Console Resident DCD Points
Multiplexer (MUX), data concentrator (DCU), and programmable interface unit
(PCIU) devices cannot support DCD points. The four-bit and one-bit points that
these devices provide to the console can be controlled by a console-resident DCD
point. As many as eight consoles can be configured to interact with a console-resident
DCD. The configuration designates one console as the source console in which all
DCD processing occurs and which allows other destination consoles to change the
setpoint, mode, and other parameters of the DCD.
The following figure shows a DCD Instrument Area.
Operating and Tuning Points
5-21
Figure 5-6
Console-Resident DCD Point
Operation of a console-resident DCD point is similar to other DCDs, but the
console-resident DCD point also supports a remote setpoint (RSP) mode in addition
to manual (MAN) and computer (CMPTR) modes. RSP mode causes the console to
change the setpoint to match the state of the associated discrete inputs. Note that
console-resident DCDs do not have enhanced capabilities that can be configured for
SR90 and later controller DCDs.
Controller Group Points
A Group point’s controls appear similar to DCD point controls, but group points
control sets of DCDs (as many as eight) to coordinate the actions of multiple DCD
points. You can control entire groups of pumps, motors, and valve headers through
such setpoints configured as Fill Tanks or Dump Tank B. Selecting a group point
5-22
Using DeltaV Operate for PROVOX® Consoles
setpoint automatically selects the DCD setpoints for the DCD points in the group.
The following figure shows the instrument area for a group point.
Figure 5-7
Group Point
The group setpoint and corresponding individual DCD setpoints are defined in a
group template. A group point is an advanced interface from which you can control
up to eight DCD points. The group point instrument area looks like a DCD and has
the feel of a DCD.
Change an attribute’s value by clicking on a value. A drop-down list containing the
available choices appears:

The following table shows the effects of group point mode changes on the mode of
DCD points in the group.

Changing the Mode of a Group Point...
Changes the Mode of a DCD Point in
the Group to...
from MAN to AUTO or COM
COM
from AUTO to AUTO
COM
from AUTO or COM to MAN
MAN
In addition to MAN and CMPTR modes, the Group point also has an AUTO mode.
In the AUTO mode, a Group point responds to operator setpoint changes and passes
appropriate commands to the DCDs under its configured control. The DCDs must
be in the CMPTR mode to accept these setpoint values. If each DCD functions
correctly, the proper process variable (PV) appears at the Group point that matches
the selected setpoint.
When the mode of a Group point is changed to MAN, each DCD point associated
with it by configuration is also changed to MAN mode. When the Group point is in
MAN mode, you are expected to operate the individual DCDs, and setpoint requests
are not accepted by the Group point. If the mode is switched to AUTO, each DCD
configured to it is switched to CMPTR mode. Setpoint inputs to the Group point are
then passed on to the individual DCDs.
If an individual DCD is switched to MAN mode, no immediate failure occurs. The
next setpoint command processed by the Group point fails because the DCD point in
MAN cannot accept the command. On newer controllers, if the PV does not match
the setpoint after a configured amount of time (dependent on individual component
DCDs) the Group point fails. Group point failures are reported in the MVPFLIDX
display attribute.
5-24
Using DeltaV Operate for PROVOX® Consoles
Note
Before changing the setpoint of a group point, it is good practice to reselect automatic mode
(AUTO) even if the Group point is in the automatic mode to ensure that the DCDs
are in CMPTR mode.
Operating a Group point is similar to operating a DCD. If a Group point is changed
to CMPTR mode, its DCD points are forced to the CMPTR mode also. Operator
setpoint inputs to the Group point are not accepted; however, commands from
higher level points such as LCPs, Unit points, and CHIP points are accepted. If a
group point or DCD point is under the control of a Unit point, changes in the mode
of the Unit point are passed on to these points. For example, changing a Unit point to
MAN causes related Group and DCD points to change to MAN.
Group points have two alarms: one to indicate that the point has failed (FAILED) and
another to indicate that one or more DCDs have failed (F ELEM).
Mode, setpoint, and process variable are the valid parameter selections for group and
DCD points. The PV can be changed only if the point has been tuned off scan.
Analog Input Points
The following figure shows a typical analog input instrument area. Input points have
no mode because they have no process outputs. When you click on the process
variable the slew buttons and entry field that appear seem to invite an input; however,
the change is not accepted unless the point has been tuned off scan.

as spin buttons) appear. Either enter a value or use the slew buttons to change the
value. If the point is in CMPTR mode, you can attempt to change the output value;
however, the change is not accepted.
The output value may be configured or tuned to be inverted so that it can
accommodate valves that require an inverted signal. The following figure shows a
typical analog output point instrument area.

Analog Output Point
Loop Points
There are five different types of loop points:
„
Manual loader — Provides for manual control of the output and allows an
analog value to be monitored.
„
Bias and gain — Adds bias to the PV and then multiplies by the gain.
„
Signal selector — Selects either the highest (or lowest) of up to four input values
and passes it on to the output value.
Operating and Tuning Points
5-27
„
Proportional-derivative with bias — Adds operator-supplied bias to a loop
with proportional and derivative action.
„
PID (proportional-integral-derivative) — Classic PID loop action.
Loop point configuration can range from simple to complex. Some of the factors
involved in complex applications are:
„
Setpoint tracking
„
Feedforward
„
Cascade loops
„
Output tracking
„
Integral tracking
„
Ratio
„
Attaching an LCP before and/or after the loop algorithm
The information that follows pertains to a simple PID loop because complex loop
configurations are site dependent. In a loop point faceplate the process variable
appears as a yellow bar, the setpoint appears as a white bar, and the output appears as
a cyan (light blue) bar. The action of the loop may be direct or inverted, and the
algorithm can accommodate valves that increase to open or increase to close. These
items are set by configuration but are tuneable. The PID parameters are initialized by
configuration but can be tuned.
If the point is in MAN mode you can change the output by entering a value in the
output entry field or by using the slew buttons. If the point is not in MAN you can
attempt to change the output value; however, the change is not accepted.
If the point is in AUTO mode you can change the setpoint by entering a value in the
SP field or by using the mouse on the SP slew buttons. If the point is not in AUTO,
changes may be accepted depending on the mode.
If the point is in RSP mode, inputs are not accepted because the loop is in control of
the output and another point (typically another loop) is providing the setpoint. PID
loops do not accept the RSP mode unless this function is configured.
If the point is in the SUP (supervisory) mode, inputs are not accepted because the
loop is in control of the output and another point or a computer program is providing
the setpoint. PID loops do not accept the SUP mode unless that function is
configured.
If the point is in DDC (direct digital control) mode, changes to the output are not
accepted because another point or computer program is providing the output. PID
loops do not accept the DDC mode unless configured to do so.

Using DeltaV Operate for PROVOX® Consoles

To change a value click on the value and an entry field and slew buttons appear:
Either enter a value in the entry field or use the slew buttons to slew to the desired

Console EPCI Points
EPCI points calculate accumulation and rate values from raw pulse counts. When the
EPCI point originates in the console, the console receives process data from
controller pulse count input (PCI) points and then performs the calculations.
PCI points monitor the register values of DM6370-Series pulse count input cards, or
Type CL6721 discrete input cards with Type CL6761 pulse count input termination
panels, which connect to field devices such as flow meters. Flow meters emit electrical
pulses, and the card counts the pulses in its register. The card’s register records as
many as 65,536 pulses before returning to zero.
When a UOC/IFC sources the EPCI point, the controller performs the accumulation
and rate calculations.
The following figure shows a typical EPCI point instrument area.

Console EPCI Operation
A console EPCI point displays the following information on the faceplate and
instrument area:
„
An accumulated value of pulses, scaled to the correct engineering units (The
EPCI accumulation continues to increase even though the register in the PCI
card returns to zero.)
„
The rate at which pulses change, scaled to the correct engineering units
„
Raw pulse count
For example, a console EPCI point calculates and displays a flow in pounds per
minute using the pulse count rate. Also, a console EPCI point accumulates and
displays an amount in pounds using an accumulated pulse count.
Setting the Console EPCI Point Accumulation Counter
You can tune a console EPCI point’s accumulation counter to zero or to any desired
value within the console’s 12-digit limit. When you set the accumulation counter for a
console-sourced EPCI, you also set the accumulation at the console. This does not
affect the PCI point. Setting the accumulation counter for a UOC/IFC EPCI sets the
accumulation at the controller.
Console Accumulation Points
Accumulations are the totals of selected attributes. The configuration process
establishes an accumulation for the desired attributes of a selected point. Typically, a
variable such as flow (gallons per minute) is accumulated to yield total gallons. It is
also possible to accumulate pump-on time. After download, the console records the
attribute values at configured intervals.
The recorded values are called samples. The console periodically totals these samples,
making them available to you through the accumulation-point faceplates. For each
accumulation, the console provides a total and an average of the attribute samples for
the current hour, shift, and day. The previous hour, shift, and day numbers also appear
in the instrument area and are available on a faceplate.

Accumulation Point Values
Depending on the point type, accumulation values appear in one of two ways:
„
For discrete-point accumulations, the value shown is the amount of time the
point spends in either the ON or OFF state, depending on configuration which
could be used for pump-on time, for example.
„
For all other point types, accumulation values are in engineering units.
The following figure shows the instrument area for an accumulation point.

Accumulation Point Integrity
Each accumulation point has 12 data-integrity flags. The following occurrences set an
integrity flag:
„
AC or DC power failure
„
Bad point status
„
Point download
„
You modify an accumulated value
„
You modify the console time
Console Maintenance Points
The following figure shows the instrument area for a typical maintenance point. Note
that it appears similar to a four-bit discrete output point. The differences are that you
cannot change the mode or any of the discrete values on a maintenance point.
5-34
Using DeltaV Operate for PROVOX® Consoles
Figure 5-13 Maintenance Point
The maintenance point lets you monitor the status of devices on the PROVOX
highway. It is possible to configure maintenance points for devices that do not
support integrity points. The maintenance point informs you of communications
problems, such as whether the traffic director has the device selected on the primary
and secondary highway and whether or not they are communicating.
Information from the maintenance point is usually shown on the maintenance display.
If the internal integrity of a device changes to bad, the maintenance point associated
with that device can be configured to go into alarm. Depending on the definition for
Operating and Tuning Points
5-35
the maintenance display, this alarm can cause the device representation in the display
to flash or change color. The alarm can also cause the console horn to sound.
Acknowledge the alarm by clicking the Ack button.
The console polls the primary and secondary network traffic directors (NTD), if
available, as well as the primary and secondary local traffic directors (LTD) for
integrity information.
The poll of each NTD yields:
„
The internal integrity of the NTD
„
The composite integrity of its local area
„
The internal integrity of its network devices
„
The device-select status of its LTDs
„
The device-select status of its network devices
After polling the NTDs, the console polls each LTD. The poll of each LTD yields:
„
The internal integrity of the LTD
„
The internal integrity of each of its local devices
„
The device-select status of each local device
If an LTD or NTD fails to respond to a polling request, all the subordinate devices
reporting to that LTD or NTD receive a BAD status.
The console compares the results of each polling routine with the data from the
previous poll. The console indicates integrity changes on the maintenance point and
may show changes on the maintenance display.
Console Integrity Points
The integrity point (supported by consoles and SR90 and later controllers only)
provides you with device integrity information such as whether or not there are any
problems with a specific device, how critical existing problems are, and what type of
action needs to be taken. The console brings device-related integrity problems to your
attention through standard console alarm capabilities, internal integrity displays,
maintenance displays, or logged messages.
Integrity Point Alarms
A fault condition activates Integrity point alarms. The severity of the fault condition
determines which alarm is activated. An alarm activates and the console logs an alarm
message every time a new or different fault condition occurs. If a fault condition
5-36
Using DeltaV Operate for PROVOX® Consoles
occurs while the appropriate alarm is active, that alarm is reactivated to indicate a new
fault condition. The list below defines alarms for the integrity point:
„
Alarm A — This alarm indicates a potentially CRITICAL situation. A device is
unavailable or the console has lost control of at least one loop. Take corrective
action immediately.
„
Alarm B — This alarm indicates a potentially URGENT situation. Control may
be lost shortly. Take corrective action as soon as possible.
„
Alarm C — This alarm indicates a WARNING situation. Control could be lost if
another failure occurs. Take corrective action as soon as it can be scheduled.
„
Alarm D — This alarm indicates that the console has detected a MINOR
problem. Control has probably not been affected. Take corrective action when it
is convenient.

Integrity Point Instrument Area
To access a specific integrity point faceplate, call up a display containing the point or
request the point by name in the instrument area. The instrument area for the
integrity point appears, as shown in the following figure.
Figure 5-14 Integrity Point
Fault Logging
The console hosting the integrity point logs fault conditions detected during integrity
point processing. This is in addition to the alarm logging which occurs as part of
normal point alarm processing. The console logs an All Okay message when all fault
5-38
Using DeltaV Operate for PROVOX® Consoles
conditions have been cleared. It does not log informational messages because they are
not considered fault conditions.
Note
For more information about integrity points, refer to the manual Configuring the SRx
Controller Family (CE12.0:CL6640).
DDPs
The integrity point has all the standard console local point DDPs.
Controlling Device Error Reporting
ERR reporting is automatically disabled for all devices that have an integrity point.
This eliminates the ERR reporting, which may affect as many as 500 points, that
would otherwise occur when a backup device is lost due to a redundant switchover.
The console disables ERR reporting to all devices it sends unsolicited data to. SR90
and later devices support selective ERR reporting and will continue ERR reporting
for devices that do not have an integrity point.
Integrity Point Messages
Information on integrity point messages is available in the Instrument Area help
under Point Messages and Error Codes.
Logic Control Points
Logic control points provide access to and control of interlocking, sophisticated loop
functions, and other customized continuous applications. Each LCP has an associated
function sequence table (FST). The FST is a signal-processing algorithm composed of
individual functions (instructions) that define a control strategy.
The LCP includes 12 registers:
The registers are also known as configured variables.
„
Four floating-point variable registers
„
Four registers that hold either integer or percent-values (configurable)
„
Four Boolean registers
The LCP instrument area provides a means of accessing the 12 registers and starting,
stopping and advancing the FST. The LCP and the designated or configured FST
Operating and Tuning Points
5-39
reside in either the unit operations controller (UOC), integrated function controller
(IFC), or extended multiplexer controller (EMX).
Each LCP is configured to execute in one of the following ways:
•
Continuous execution — The configuration defines the execution rate.
•
Loop execution — The controller synchronizes the execution with a specified
loop.
•
One-shot execution — The LCP stops after one execution.
The following figure shows a typical LCP instrument area.
Figure 5-15 Logic Control Point
5-40
Using DeltaV Operate for PROVOX® Consoles
Configured Variables
During configuration, for each configured variable (register), the configuration
engineer sets whether you can change its value. The engineer can also configure a
description for each register. If you are expected to change a value, writing will be
enabled for that variable. If the FST code is showing you some calculated or measured
value, the variable is probably not write enabled.
To change a variable value click on the variable in the list. The CV dialog opens with
the selected variable. The appearance of the dialog depends on whether the variable is
boolean or numeric as shown in the following figure.
Figure 5-16 LCP CV Dialogs
The first 12 characters of the configured description appear adjacent to the CV
number in the dialog title bar. To change a numeric variable’s value, enter the desired
value in the New Value: field. To change a boolean variable's value click on the toggle
button that corresponds to the desired on or off word. The configured ON and OFF
words appear adjacent to the toggles.
Operating and Tuning Points
5-41
Click on the OK button to accept your change and close the dialog. Click on the
Apply button to accept your change and leave the dialog in place. Click on the Cancel
button to close the window without changing the current value.
If you load a different point in the instrument area while the CV dialog is open, the
dialog closes without accepting any current change.
LCP Modes
LCPs operate in one of two modes: manual (MAN) and computer (CMPTR). If the
LCP is in manual mode, you control the LCP. If the LCP is in computer mode, unit
operations and other LCP/FSTs control the LCP, although you may change the LCP
mode to manual if the configuration of the LCP allows it. When you control the LCP,
you can start, advance, and stop the FST, and change modes.
The configuration defines the ability to select and change the 12 variables; LCP mode
does not affect this ability.
LCP States
An LCP exists in one of these states:
„
IDLE — Valid only on one-shot and continuous LCP types. While the LCP is in
the idle state, the controller does not process FST instructions. A continuous
LCP enters this state when it receives a stop command; a one-shot LCP becomes
idle when it completes execution.
„
ACTIV — When a one-shot or continuous LCP receives a start or advance
command, it enters the active state and executes FST instructions. A loop-type
LCP is always in the active state under normal operation.
„
HOLDG — Valid when the associated FST is downloading.
„
O/S (OUT-OF-SERVICE) — In either the idle or active state, the LCP
continues to monitor for failure, communicate operating data, and so on. To stop
all LCP processing, including the ability to stop, start, and advance the FST, place
the point out-of-service. The system places the LCP out-of-service when it traces
the LCP and the LCP is in the breakpoint mode.
„
WAITG — A WAIT instruction has suspended the execution of a continuous
LCP. (P3.0 and later controllers only.)
Refer to the online help for failure index values for FSTs.
5-42
Using DeltaV Operate for PROVOX® Consoles
LCP Operation
In addition to changing the mode of the LCP and the 12 registers, you can use the
LCP instrument area to run FSTs. When you click the Operate… button the
following dialog appears.
The three buttons do the following:
„
Start — Start an FST. The Start button starts the FST at the first instruction. The
FST code may specify a RESUME location. The RESUME location can be at the
beginning of the code. The LCP state must be IDLE and the mode must be
MAN to accept a start request from an operator. A message stating that the LCP
started execution is logged to the Event Journal.
„
Stop — Stop an FST. The LCP continues the current pass through the FST until
it reaches an END instruction. The controller then sets the LCP state to IDLE.
The Stop button is valid only for continuous LCPs. The LCP state must be
ACTIV or WAITG and the mode must be MAN. A message stating that the LCP
stopped execution is logged to the Event Journal.
„
Advance — Advance an FST. The LCP continues a previously stopped FST,
steps to the next instruction if the LCP is in single instruction mode, or steps to
the next instruction if the LCP state is WAITG and Cancel Wait is enabled (P5.0
and later controllers only; WAIT instruction).
If you previously stopped the LCP by clicking the Stop button, the Advance
button restarts the FST at the current RESUME location. The Advance button is
valid only for continuous and one-shot LCPs that are IDLE or for continuous
LCPs that are in the WAITG state. The LCP mode must be MAN. A message
stating that the LCP advanced execution is logged to the Event Journal.

Information on LCP Fail Indexes is available in the Instrument Area help under Point
Messages and Error Codes.
Unit Points
Unit points provide batch control of a process unit, which is a grouping of plant
equipment (for example a reactor and its associated valves, pumps, and agitators).
Although you can operate units independently, they are frequently operated in parallel
with other units in the plant. The Unit point is resident in the controller.
A Unit point runs operations—configured instructions that define a batch process.
The Unit point provides a view of the batch as it progresses. It also provides the
ability to stop at intermediate steps if desired. It is also possible to start the batch at
one of the intermediate steps. All operations have at least one fail step configured.
You or the unit operation can force the Unit point to fail, which executes the code for
the configured fail step.
The Unit point has three modes: computer, auto, or manual. In the computer mode,
the Unit point is controlled by either operator input or another point. The other point
is typically a Console Activity point. In the auto mode, only the operator has control
over the Unit point. Commands from other points are not accepted.
When the Unit point is in the manual mode, the process is not controlled by the Unit
point. All processing of step instructions stops, and the unit state does not change.
Configuration can prevent placement of the unit point in the manual mode; however,
this restriction is tuneable.
Caution
The unit point does not control the process when you place it in manual
(MAN) mode.
The following figure shows the instrument area for a unit point.
5-44
Using DeltaV Operate for PROVOX® Consoles
Figure 5-17 Unit Point
A unit operation is a set of instructions that defines how to control a unit. To perform
multiple control tasks, several operations may be defined for the same unit. For
example, a reactor may have operations such as charge, react, heat, cool, and dump
defined.
Operating and Tuning Points
5-45
Unit Modes
Unit points have three valid modes:
„
Computer — a CHIP program, activity points, or you control the point and thus
direct unit operation.
„
Auto — only you can control the point and its operation. If an activity point tries
to manipulate the unit point, the activity point fails. The unit point ignores
routine CHIP program commands.
„
Manual — the process is not controlled—all processing of step instructions
stops, and the unit state does not change. Configuration can prevent the unit
point being placed in manual mode.
When the mode of a unit point changes, the modes of the points it controls may also
change. The following table shows the effects of unit point mode changes on the
mode of points controlled by the unit point.

Unit Operator Action Requests (OARs)
The unit point can be configured to prompt you for information it needs to continue
the operation. The console alerts you to an OAR through either:
„
The unit point tags displayed in the OAR area of the alarm banner
„
OARP appearing in the unit point faceplate
If the unit point sends another OAR to the console, the new OAR appears in the
OAR area until you respond to it. Depending on the configuration the OAR may also
sound the horn or flash until you acknowledge it. The OAR may prompt for YES,
NO, ACK, or a numeric response. Depending on configuration, an OAR remains
active until answered or until it times out and a configured default value answers.
The OAR area of the main window, if enabled, contains the four highest priority
OARs pending. To see information about the OARs, click on the OAR Summary
button in the toolbar. To see the associated graphics display for an OAR, click on the
OAR in the OAR area or in the OAR summary. The point controls for the unit point
that sent the OAR appear in the main instrument area and the corresponding graphics
display appears in the display area.
The Unit Point Instrument Area
The HOLD and STATE fields of the unit point instrument area can have several
values.
The HOLD Field
The HOLD (hold phase) field can have one of three possible values:
„
Blank — no hold has been requested
„
Phase_name — the operation holds at Phase_name
„
NXT LEGL — the operation holds at next legal phase
State Field
A unit point can be in any of several states. In the following list the word that appears
in the instrument area is shown in parentheses:
„
OUT-OF-SERVICE (O/S) — The unit is inactive and does not have an
operation assigned to it. This state inhibits all operator commands except those
that allow the unit to be placed back in service.
„
IDLE (IDLE) — The initial state of a unit before you load an operation, after
you cancel an operation, or after you successfully complete an operation.
Operating and Tuning Points
5-47
„
ACTIVE (ACTIV) — The system is executing the operation.
„
WAITING (WAITG) — The unit waits either for a response to an Operator
Action Request (OAR) or for a WAIT or WAITUNTIL instruction to be
completed.
„
HELD (HELD) — The unit is on hold at the start of a phase because of an
operator request.
„
FAILING (FAILG) — The unit detects a failure and is processing the failure
step.
„
FAILED (FAILD) — The unit completes the failure step and processing stops.
Operating Unit Points
To operate a Unit point click on the Operate… button. The Unit Control dialog
opens. The dialog has three tabs: Operation, Hold, and Modify. The following
subsection explains each of the tabs.
The Operation Tab
The following figure shows how the Operation tab appears.

The dialog tab buttons and fields are:
Note
„
Operation — Select an operation to run.
„
Phase — If you have TUNE privilege you can select a phase of the currently
selected operation to start at.
„
Load/Start — Load and start the currently selected operation, or queue up as
many as four operations if the unit point is executing an operation.
If you click on the Load/Start… button when the unit is not idle, the operation is
queued.
„
Stop/Fail — Causes the controller to execute the failure step associated with the
current step and set the unit state to failing.
„
Cancel Wait — For a unit in the WAITG state and with cancel wait enabled
(CANW on the unit faceplate), sends a CANCEL WAIT command to the unit.
The CANCEL WAIT command causes the unit to revert to its previous state,
either active or failing, before the state was changed to waiting.
Operating and Tuning Points
5-49
Cancel Wait then forces the operation to continue with the next step instruction
in the sequence following the instruction that caused the unit to go to the waiting
state. Where allowed, you decide whether to continue without the programmed
time or conditions being met. Exercise caution when using CANCEL WAIT.
„
Retry Operation — Sends a RETRY/NORMAL command to a unit point
operation in the FAILED state. Before issuing this command, examine the unit
point’s faceplate and note the associated fail index and fail instruction. The
RETRY/NORMAL command moves the unit back to the specified failure retry
step, changes the unit state to active, and forces the operation to begin processing
as before.
The Hold Tab
The following figure shows the Hold tab.
Figure 5-19 Unit Control Holds Tab

„
Hold Next — Requests a hold in the specified operation at the next legal hold
phase.
„
Clear Op Hold — Clears any hold command that is pending. It does not affect
the state of the unit.
„
Continue From Hold — Sends a PROCEED command to the unit. The
PROCEED command removes the hold request, places the unit into its previous
state, either active or failing, and causes operation processing to continue.
The Modify Tab
The following figure shows the Modify tab.

„
Change Phase — Immediately advances the operation to the first step of the
specified phase. You must have TUNE privilege to use this button.
„
Cancel Operation — Cancels the current operation and all (as many as four)
queued operations. This is valid only if the unit is in the FAILD state. The console
then sets the unit state to idle.
OARs and Privilege Levels
Access to console information is protected through both passwords and privilege
levels. The action you are able to and are required to make after you select a point with
an OAR depends on the type of OAR and your user privilege. If an OAR is pending,
OARP appears in the STATUS field of the point’s instrument area and the point
appears in the OAR area of the main window, if it is enabled. To acknowledge or
respond to an OAR click on the OAR button in the unit point instrument area. The
Operator Action Request dialog appears as shown in the following figure.
Figure 5-21 OAR Dialog
The OAR word appears in the OAR Type: field. The OAR message, if any, is displayed
in the message field in the middle of the dialog. The other buttons and fields that
appear on the dialog depend on the type of OAR.
If you change the point in the instrument area the dialog closes without accepting
changes not confirmed.

value appears next to the FAIL: indicator in the instrument area and faceplate. The fail
index is reported in the FI display attribute.
Information on the unit point failure index values is available in the Instrument Area
help under Point Messages and Error Codes.
Console Activity Points
An activity point is the highest level of automatic batch control. Many of the tasks at
this level involve identifying and scheduling batches. You must maintain an identity
for each batch to track the batch as it progresses and to store information for batch
end reports.
Activity points schedule the progress of the batch, coordinating the use of units and
unit operations. Activity points also provide your interface to the batch.
The following figure shows an activity point instrument area.
Operating and Tuning Points
5-55
Figure 5-22 Activity Point
An activity point is a console-resident point. A console processes as many as 32
activity points and updates additional consoles (as many as eight) that require the
activity information. You can operate an activity point from any of the consoles to
which you target the activity point.
You have the same degree of control with a target point as with a source point. Each
console supports as many as 32 source activity points and receives an unlimited
number of target points.
The console supports redundant activities.
5-56
Using DeltaV Operate for PROVOX® Consoles
Activity Points and Switchovers
There are some special considerations to keep in mind when Switchovers involving
Activity points occur.
During normal operation prior to the switchover the Active server sends unsolicited
messages to the Standby server to keep the operating data (only) in the Activity point
in the Standby server updated. The reporting rate from the Active to the Standby
server should be set to 1 second exception.
The Standby server can take over either manually if the operator requests or
automatically, if automatic switchover is enabled. The Standby server becomes the
Active server.
After a switchover occurs, the Activity point in the now active Server loads the
Procedure, Point Set, Grade, Process, and so on to match the last unsolicited update
received from the formerly Active console. The activity state is set to FAIL. An
operator requested RETRY drives the state to IDLE.
However, the grade data in the Active server after a switchover will not include
changes tuned from the Active server before the switchover (the previously active
server). Further, the Active server after a switchover will not have any acquired point
sets or common alarms. Tuned grade data, acquired point sets, and common alarms
are not copied from the Active to the Standby server during a switchover.
In addition there is no record of any Unit operations that may have been running or
queued by the formerly active Activity point.
Note that history is only kept by an Active Console Data Server.
After the switchover the you must manually restart the Activity. You must Abort the
procedure and step the unit point's operation to a phase at which the Activity can be
resumed. You must manually clean up the acquired point sets and resynchronize the
Active and Standby servers.
Activity Point Modes
The activity point operates in one of two modes:
„
COMPUTER — only a CHIP program can control the point, and thus direct

Procedures
The set of instructions that make a product is called a procedure. Procedures are also
often called recipes or formulations. Procedures are the highest level of batch control
strategy in the console.
A procedure consists of two parts: product data and a sequence of operations.
Product data is any numerical data that is required by the unit operations and that may
vary between batches. The sequence of operations is the order in which unit
operations must be performed, such as charge, heat, cool, and dump to make a
product.
Often, a procedure makes several variations, or grades, of a single product. For
example, each grade can vary in the amount of an ingredient to add, or the
temperature setting, such that a unique product is produced using the same basic
recipe (procedure).
Procedures are defined to run on point sets. A point set contains the unit points and
other points necessary to run a batch. A point set defines the equipment path the
procedure uses to make a batch. A procedure may be defined to run on several point
sets. When several point sets are available, you select which point set to use with a
procedure.
Procedures are built from one or more processes. A process is a block of control
statements that accomplish a specific control function within the procedure. Each
process is built of procedure statements. Primarily, these statements acquire and use
unit points in the unit operations controller to produce the batch. The configuration
engineer usually configures the unit points required for each activity into one or more
point sets.
Activity Process Instructions
An activity process is a basic block of automatic batch control. It is also the lowest
level of operator control in a procedure. One procedure can have as many as 16
activity processes. Each activity process in a procedure contains one or more process
instructions.
The console may temporarily hold a batch when a procedure execution is beginning
an activity process. The configuration engineer uses the hold instruction to control
whether you can temporarily halt the execution of a procedure at the beginning of a
process.

Activity Point States
The activity point can be in different states or conditions. In each state the point has
certain properties or characteristics. The allowable transitions between states and the
actions necessary to cause the transitions are shown in the following figure.
In the following figure the text in boxes represents activity point states. The text
outside of boxes indicates activity point controls and conditions.
Figure 5-23 Activity State Transition Diagram
The following subsections explain each of the activity point states.
Operating and Tuning Points
5-59
NOT LOADED State
The activity does not have a procedure loaded. When an activity point goes to the
NOT LOADED state, the system sets the point’s parameter values as follows:
„
Abort requests are enabled.
„
Abort is not requested.
„
Fail limit is WARNING.
„
Iteration limit, the current iteration, the statement index, the start time, the pointset detailed display parameters (DDPs), the grade data, common alarm data, and
end time are all set to 0.
„
No holds are set on processes.
„
The procedure name, grade name, point set name, and process name are blank.
Two things happen if history information exists or if the point is still collecting data
through the common alarm list at the time the point changes to the NOT LOADED
state. First, the system removes all common alarm points from the common alarm
list. Second, the system deletes the history information.
An activity point goes to the NOT LOADED state after a total console download or
after you or a CHIP program issues a REMOVE command when the point is in the
IDLE, BATCHEND, FAILED, or ABORTED state. If the you or a CHIP program
loads the activity point when it is in the NOT LOADED state, the point changes to
the IDLE state.
IDLE State
The activity has a procedure loaded and is ready to start the procedure or load another
procedure. When an activity point goes to the IDLE state, the system sets:
„
Abort requests enabled
„
Abort is not requested
„
No holds on processes
„
Procedure name, grade name, point-set name, and batch ID as specified in the
load request
The system also makes a copy of the grade and point-set data as selected in the load
request.
When an activity point is in the IDLE state, you can load an activity, start an activity,
or remove an activity. You can load and start an activity point using a CHIP command
that takes the activity point to the ACTIVE state. If you load the activity, the point
5-60
Using DeltaV Operate for PROVOX® Consoles
returns to the IDLE state with the new load specifications. While an activity is IDLE,
you can tune the grade parameters if you have TUNE privilege.
After an activity is started, if you have TUNE privilege you can still tune the grade
parameters, but changes may or may not be sent to the units, depending upon the
instructions already processed by the activity. Starting the activity takes it to the
ACTIVE state, and removing the activity takes it to the NOT LOADED state. Refer
to the Activity Point State Transition diagram for an overview of activity state
transitions.
ACTIVE State
The activity is executing a procedure statement. In the ACTIVE state, the activity
processes instructions. If an instruction requires a wait condition, the point goes to
the appropriate WAIT state (AQUIREWT, UNITWAIT, SCHEDULE, PRINTING,
or DELAY). When the wait ends, the point returns to the ACTIVE state to process
the next instruction.
If abort is enabled for an activity point in the ACTIVE state, and you or the CHIP
program makes an abort request, the activity state becomes ABORTED. If abort is
disabled when the activity point receives an abort request, the activity remains in the
ACTIVE state and ABORT:DI RE (disabled, requested) is noted on the activity
faceplate.
If the procedure ends successfully while the activity point is in the ACTIVE state, the
state changes to BATCHEND. However, if an error condition occurs, the state
changes from ACTIVE to either WARNING or FAILED, depending on the severity
of the error and the current fail level.
HOLDING State
The activity is holding at the start of a process due to an operator request. Activities
hold at the beginning of processes that have been configured to accept a hold request.
When an activity begins a new process for which a hold has been requested, the
Operating and Tuning Points
5-61
activity point goes into the HOLDING state. The point remains there until one of the
following conditions occurs:
„
You or a CHIP program requests the activity to proceed. The activity point
becomes ACTIVE and processes the first instruction of the process on which it
was holding.
„
You or a CHIP program request the activity to abort. The activity point becomes
ABORTED.
„
A redundancy switchover occurs.
„
You update the console configuration.
UNITWAIT State
The activity is waiting for a unit operation to complete. The activity point continues to
wait, even if the unit point fails. When an activity processes a WAITUNTIL
instruction, it changes to the UNITWAIT state and waits for the operation to
complete. The point remains there until one of the following conditions occurs:
„
Note
The specified operation completes.
If the specific operation FAILS and an operator with TUNE privilege subsequently
cancels the OPERATION on a unit point, the activity point remains in the
UNITWAIT state until either an operator with TUNE privileges or a CHIP
program requests an activity CANCEL/CONTINUE.
„
You have TUNE privilege and you or a CHIP program request a Cancel/
Continue.
„
You or a CHIP program request an abort while abort is enabled.
„
A redundancy switchover occurs.
„
You update the console configuration.
AQUIREWT State
The activity is waiting to acquire a point for operation. The activity cannot acquire any
of the points listed in the ACQUIRE instruction because their resource attributes are
zero. The activity point tries to acquire the points every15 seconds until one of the
following conditions occurs:
5-62
„
A point is successfully acquired.
„
An error occurs or the activity receives a highway error response.
„
You have TUNE privilege and you or a CHIP program request a Cancel/
Continue.
Using DeltaV Operate for PROVOX® Consoles
„
You or a CHIP program request an abort while abort is enabled.
„
A redundancy switchover occurs.
„
You update the console configuration.
WARNING State
The activity encounters a nonfatal condition (based on the current fail level) while
executing a statement. If a nonfatal error occurs during the processing of an
instruction or if redundancy communications are bad, the activity point goes to the
WARNING state and the system logs a message. This state does not indicate the
severity of the error; rather, it indicates that the error is below the current fail level.
When the point goes to the WARNING state, the fail value changes to the number of
the failure that caused the error.
The WARNING state is a transitory state. The activity only enters it long enough for
the system to log a message. Once the system logs the transition, the activity
continues.
FAILED State
The activity failed during execution of a statement. The faceplate and the instrument
area indicate the statement number and fail number. Depending on the PPA mode for
the activity point, a transition to the FAILED state activates the activity point’s B
alarm word.
If a history is being kept, the console logs an alarm activation message, which is
logged into the batch history. The point exits the FAILED state when one of the
following conditions occurs:
„
You or a CHIP program request a Retry. The activity point returns to the
ACTIVE state and re-executes the instruction that failed.
„
You or a CHIP program request a report. The activity point enters the
PRINTING state until the report prints on the source console. The activity point
then returns to the FAILED state.
„
You or a CHIP program request a Remove. Then the point goes to the NOT
LOADED state.
„
A redundancy switchover occurs.
„
You update the console configuration.
Operating and Tuning Points
5-63
ABORTED State
An activity point changes to the ABORTED state if two things occur:
„
Abort is enabled.
„
The activity point receives an abort request from you or from a CHIP program.
The system defaults to abort enabled when you or a CHIP program loads the activity
point. The procedure statement DISABLE ABORT can, disable abort, however,
while a subsequent ENABLE ABORT can re-enable it.
If abort has been enabled, either you or a CHIP program can request an ABORT, and
the activity state goes to ABORTed. If, however, abort has been disabled, and you or
a CHIP program requests an abort, the system queues the request, but no abort
happens until the activity processes either the ABORT ENABLE or the ABORT IF
REQUESTED instruction. If an abort is pending, either you or a CHIP program can
request a CLEAR ABORT.
Depending on the PPA mode for the activity point, a transition to the ABORTED
state may cause the system to print the activity’s alarm activation message, log the
message to history (if the console is keeping history), and activate the A alarm word,
and depending on the current PPA state, it prints the alarm activation message,
displays the configured A alarm word and logs the message to history. The point exits
the ABORTED state when one of the following conditions occurs:
„
You or a CHIP program requests a batch end report. The activity point enters the
PRINTING state until the report prints. After the report prints, the activity point
returns to the ABORTED state.
„
You or a CHIP program requests to remove the procedure from the activity. The
point goes to the NOT LOADED state.
„
A redundancy switchover occurs.
„
You update the console configuration.
SCHEDULE State
The activity is waiting for the completion of a CHIP program. The activity point must
be in the CMPTR mode to accept the CANCEL WAIT request required to exit this
state.
5-64
Using DeltaV Operate for PROVOX® Consoles
An activity point enters the SCHEDULE state when it processes a SCHEDULE
instruction that has WAIT as a first value. The point exits the SCHEDULE state
when one of the following conditions occurs:
„
A CHIP program notifies the activity point that the program is finished by
sending a cancel-wait request. Then the point returns to the ACTIVE state and
processes the next instruction.
„
You have TUNE privilege and you request to cancel and continue. The point
returns to the ACTIVE state and processes the next instruction.
„
You or a CHIP program requests an abort while abort is enabled. Then the point
goes to the ABORTED state.
„
A redundancy switchover occurs.
„
You update the console configuration.
DELAY State
The activity executes a delay procedure statement and waits for the time delay to
expire. The delay state timer is shown on the faceplate and the instrument area
controls, and the delay time limit is a tunable DDP.
An activity point changes to the DELAY state whenever it processes a DELAY
FROM instruction that includes delay greater than zero. The activity also enters the
DELAY state if the delay time is zero for a DELAY FROM (NOW) instruction. The
activity delays for one minute.
The point exits the DELAY state when one of the following conditions occurs:
„
The absolute delay equals the delay timer (unless this is the zero case mentioned
previously). The process has completed the delay, and the point returns to the
ACTIVE state and processes the next instruction.
„
You have TUNE privilege and you change the delay timer so that it is equal to or
less than the delay timer on the point’s faceplate (unless this is the zero case
mentioned previously). This tuning satisfies the delay condition. The point
returns to the ACTIVE state and processes the next instruction.
„
You have TUNE privilege and you or a CHIP program requests a cancel and
continue. The point returns to the ACTIVE state and processes the next
instruction.
„
You or a CHIP program requests an abort while abort is enabled. The point goes
to the ABORTED state.
„
A redundancy switchover occurs.
„
You update the console configuration.
Operating and Tuning Points
5-65
PRINTING State
The activity is printing a batch end log at the source console (the active console in a
redundant pair). You can request the report from the instrument area. The BATCH
END LOG instruction also causes a report to start printing. The point exits the
PRINTING state when one of the following conditions occurs:
„
The printer on the source console notifies the activity point that the report is
printed. When the point gets this notification, the point returns to its previous
state.
„
You have TUNE privilege and you or a CHIP program request a cancel and
continue. The report printing is aborted and the activity point returns to the
ACTIVE state and processes the next instruction if the BATCH END LOG
instruction was processed. If you requested the report, the point returns to its
previous state.
„
You or a CHIP program request an abort while abort is enabled. The point goes
to the ABORTED state if the BATCH END LOG instruction was processed. If
you requested the report, the point returns to its previous state.
„
A redundancy switchover occurs.
„
You update the console configuration.
BATCHEND State
The activity has executed the last instruction in the last process of the last iteration of
a procedure. While in the BATCHEND state, the activity history is still available to
batch end reports or through requests from a CHIP program for batch-end data
access.
If you load this activity, it changes to the IDLE state. If you request a start, the point
goes to the ACTIVE state. If you request a batch-end log, the activity point enters the
PRINTING state until the source console prints the report, and then it returns to the
BATCHEND state.
DOWNLOAD State
You have updated the configuration or compressed the database. An activity point
enters the DOWNLOAD state when you request a partial download merge while an
activity is running. When the system completes the merge or you cancel the merge,
the point returns to its previous state. An activity point does not accept operator or
CHIP program requests while it is in the DOWNLOAD state.

„
Procedure — A read-only field that displays the currently loaded procedure
„
Process — If you have TUNE privilege, enter the process at which you want to
start the procedure. If you have OPERATE privilege the first process is selected
and you cannot change it.
„
Iterations — Enter the number of iterations (batches) to run from 0 through
255.
„
Start — Start the procedure at the indicated process.
„
Remove — Returns the activity to the NOT LOADED state and deallocates any
batch history the activity holds. This button is available when the activity is
FAILED, ABORTED, IDLE, or BATCH END. If the activity state is FAILED,
examine the activity’s instrument area and note the associated fail index and fail
statement before using Remove.
Using DeltaV Operate for PROVOX® Consoles
The Commands Tab
The following figure shows the Commands tab.
Figure 5-26 Activity Control Commands Tab
The tab contains the following fields and buttons:
„
Continue — Take an activity out of the HOLDING state for the current
iteration of the procedure. The activity hold request is not removed so that in
subsequent iterations, the procedure executes the hold again.
„
Retry — Re-execute the procedure statement that caused the procedure to fail.
Before issuing this command, examine the activity’s instrument area or faceplate
and note the associated FAIL index and FAIL statement. Once the offending
cause is cleared, you can attempt a retry. If the retry is successful, the activity
continues processing.
For example, when an activity attempts to operate a unit point that is not in the
CMPTR mode, the activity point fails and displays fail index 17, along with the
statement number for the OPERATE USING procedure statement. The fail
code information from the online help tells you that the unit point is not in
Operating and Tuning Points
5-71
computer mode and instructs you to change the mode to COMPUTER and issue
the activity point retry command.
„
Caution
Cancel And Continue — Cancels the following current activity wait states:
UNIT WAIT, ACQUIRE WAIT, DELAY, SCHEDULE, OR PRINTING. This
command is valid only if you have TUNE privilege.
Be careful when issuing this command, especially if the current state is
ACQUIRE WAIT. Note that ACQUIRE WAIT typically indicates that a unit
required for the batch is not available.
Subsequent CANCEL/CONTINUE commands may disrupt batch
operations. See the information on UNIT WAIT in the Activity States
subsection to determine the effects of CANCEL/CONTINUE.
„
Abort Request — Request the activity to abort the current procedure
immediately if the configuration enables abort (displayed on faceplate and in
instrument area as ABORT: EN), or as soon as you enable abort during execution
of a procedure (displayed on activity faceplate as ABORT: DI).
Abort is valid in the HOLDING, WARNING, or WAIT states, although the
configuration engineer is responsible for enabling and disabling the abort feature
of the activity point.
Caution
The ABORT REQUEST command cannot be retried once you abort the
activity. If, however you have requested the abort and have not yet executed it
(displayed on activity faceplates as ABORT: DI REQUESTED), you can issue
the CLEAR ABORT command.
See CLEAR ABORT and ABORTED state for further information.
If you abort a procedure, the units and operations in the UOC can continue to
operate the plant equipment if the activity started or queued the operations
before the abort request. The Abort request aborts only the supervisory capability
of the activity and does not affect the units that are already running. To shutdown
5-72
Using DeltaV Operate for PROVOX® Consoles
the plant equipment, you must control the unit points. Refer to the subsection
Unit Points on page 5-44 for more information.
„
Clear Abort — Clear an abort request (displayed on the faceplate and the
instrument area as ABORT: RE), if the activity is not in the ABORTED state.
This command is valid when the activity is IDLE, HOLD, or in any WAIT state.
„
Batch End Report — Select a report to print. The activity configuration
determines whether a batch end report prints at the end of a batch cycle. If an
activity enters the ABORTED or FAILED state, the batch end report does not
print automatically but you can print a report using the Print button
The batch end report can include information about the activity, such as when the
procedure began, the start times for each process, the time the procedure ended,
the name of the procedure, the batch identifier, the change-of-state messages, and
the number of iterations. The types of information in a report are determined
during configuration.
Note that this command is only valid when the activity is ABORTED, FAILED,
or BATCH END. You cannot request additional reports via the activity point
once the state returns to IDLE or NOT LOADED.
„
Operating and Tuning Points
Print — Print the selected report.

„
Continue — Take an activity out of the HOLDING state for the current
iteration of the procedure. The activity hold request is not removed so that in
subsequent iterations, the procedure executes the hold again.
„
Hold At Next — Request a hold at the next process that contains a HOLD
ENABLED statement.
„
Clear Hold — Clear any activity hold command that is pending. This command
is valid in any activity state except IDLE and NOT LOADED provided the
console has issued a prior hold request.
„
Hold At Process — Specify a process at which to hold.
„
Hold — Hold at the specified process.
Using DeltaV Operate for PROVOX® Consoles
Activity Fail Values and Fail Levels
There are 64 types of activity failures, and each has a fail value. These values and their
failure types are listed in the online help. Refer to the online help for information on
what action to take in response to an activity failure.
Information on the activity point fail values is available in the Instrument Area help
under Point Messages and Error Codes.
The failure value appears next to the FAIL: indicator in the instrument area and point
faceplates and in the state change message for a procedure. The failure value also
appears in the following messages: activity alarm activated, acknowledged, and
deactivated messages, and the activity state change message. In addition, the fail value
is reported in the FVAL display attribute.
The fail level determines the severity of each failure. There are three levels of failure:
warning (0), error (1), and fatal (2). Each of the 64 failure types falls under one of
these three levels. Through tuning, you indicate which failure level causes the activity
to go into the FAILED state.
Tuning Points
Many point parameters are available as DDPs (detail display parameters). These are
generally values that may need to be changed periodically, but not as often as
operating parameters.
There are two types of detail display parameters (DDPs) available:
„
Remote Parameters — Tuning parameters used by and stored in the remote
highway device (the controller). The controller:
•
•
•
•
„
Manages the point algorithm
Scans inputs from the I/O system
Services outputs to the I/O system
Sends targeted data to other devices like a console, other controller, or CHIP
at the request of the receiving device
Local Parameters — Tuning parameters used by and stored in the console. The
console:
•
•
•
Operating and Tuning Points
Requests the other device to send operating point data (including alarms) to
it, and specifies how it should be sent.
Manages the targeted points assigned to PPAs which reports to one or more
PMAs.
Maintains a list of console alarms (in Alarm Summary window)
5-75
•
•
Shows active alarms in Operator Attention List based on User Privileges and
the PPA critical level
Provides a way to manage alarms at the bit (Alarms A, B, C, & D), point, PPA,
and PMA level
Display Attributes
There is a family of display attributes that allow DDP values to be changed directly
from displays. These attributes must be configured on graphics displays. Generally, an
entry field must be configured for each DDP to be modified from the display. You
enter a new DDP value in the entry field to change the DDP.
For more information on whether your plant uses display attributes to allow DDPs to
be modified, consult with the configuration engineer.
DDP Window
The most common way to tune a point parameter is to open the DDP area of the
Point Control (Instrument Area). The following figure shows the Point Control with
both the Instrument Area and DDP area with a point selected.
5-76

Select a DDP to change
Press click, shift click, or control click in the number column to select DDPs. Selected
rows are displayed in reverse video. Use the Point Control toolbar buttons to hide or
show the selected DDPs or show all DDPs.
Operating and Tuning Points
5-77
The DDPs in the DDP area will be either Local or Remote depending on which you
selected.
This first column of the DDP area contains the DDP numbers of the DDPs currently
available for the selected point. Click on a single number to select that DDP, shift click
or click and drag to select several contiguous DDPs, or control click to select multiple
non-contiguous DDPs. After you select DDPs you can hide or show the selected
DDPs using toolbar buttons or menu options.
To change a DDP's value click in the DDP Name or Value column. If you have
sufficient privilege a Change DDP dialog appears.
Point Parameter Tuning
To tune a parameter, highlight it by clicking on it in the DDP area.
If you are attempting to tune a numeric parameter the numeric Modify DDP dialog
box opens as shown in the following figure.
Figure 5-29 Change Numeric DDP Dialog
If you are attempting to tune a boolean parameter the boolean Modify DDP dialog
box opens as shown in the following figure.

The number and name of the DDP appear in the dialog title bar.
Remote DDPs include gain, alarm trip points, OFF SCAN (OFS?), Out of Service
(O/S?), valve output high and low limits (VO HI and VO LO), and set point limits
(SP HI and SP LO).
Local DDPs include local alarm suppress, local operator changes suppressed,
messages suppressed, and operator change messages suppressed.
When you attempt to change a DDP value:

If have TUNE privilege and the change is rejected, the value can be changed only
by configuration (for example, point address and device address)
„
If the change is accepted several seconds may elapse before the DDP list is
updated
Remote DDP Tuning Concepts
There are a couple of concepts to keep in mind if you are tuning remote DDPs:
„
If a point is tuned OFF SCAN (132 OFS? — Yes or No) the point does not use
the actual process reading from the I/O system for input. Instead, you (the
operator) must enter a PV or contact input (which would be rejected under
normal point operation). There are two common uses for tuning points off scan:
„
During startup alarms and interlock code that uses the PV attribute can be tested.
(Note that tuning a point off scan does not help with code that reads the F-C-C
from the I/O system.)
Operating and Tuning Points
5-79
„
If a transmitter for a point fails during normal operation, the point can be tuned
off scan and a logical PV input used until the transmitter is repaired.
„
The points that accept operator input after being tuned off scan include DI, AI,
loop, DCD, and group points.
„
Points may be tuned OUT OF SERVICE (133 O/S? - Yes or No) which stops
the algorithm processing and point outputs.
The remainder of this section contains tuning information for some common point
types.
Console DCD Point Tuning
Information on DDPs is available from the Point Control Help menu. The
information shows the format of the remote DDP information for console DCD
Points and gives the valid values for each parameter, as well as indicating whether the
values are tunable.
The following is a description of the remote DDPs for DCD points:
5-80
„
DOSTAT — Discrete output status. There are as many as eight discrete outputs
for each DCD point. The DOSTAT value also includes diagnostic information
defined in DDP reference in the online help.
„
DISTAT — Discrete input status. There are as many as 16 discrete inputs for
each DCD point. The DISTAT value also includes diagnostic information
defined in the DDP reference in the online help.
„
REM OFS? — Remote off scan. A DCD point that is off scan prohibits alarm
monitoring. On scan allows the system to initiate an alarm state if the DCD point
fails.
„
REM O/S? — Remote out of service. While out of service, a DCD point does
not accept mode, setpoint, or parameter change requests. REM O/S also
prohibits alarm monitoring.
„
RTRYCNTR — Retry counter. This value (0 to 7) indicates how many times the
DCD point attempts to retry a requested setpoint change before indicating
failure. Evaluate whether there are valid reasons why the DCD point failed on the
first try and represented a real device failure. Use this evaluation to determine
whether you should attempt one or more retries before the DCD point enters the
failed state. Also, on critical loops, you may want to set the retry counter to 0 so
that the console recognizes the first failure to change the setpoint.
„
TRANTIME — Transition time. This period (0 to 127 seconds) provides time
for the device to receive the DCD point signal, initiate a change-of-state,
complete the change, generate the correct output signals to denote the new state,
Using DeltaV Operate for PROVOX® Consoles
and transmit the signals through the I/O device and the highway to the console.
When selecting a number for the parameter, consider the response time of the
device being controlled and allow for delays in signal transmission across the data
highway. Then add 10% of the number. Compensate for expected delays of more
than two minutes by increasing the retry counter number to prevent DCD point
failure before the required delay is complete.
„
SCAN PER — Scan period. This is the frequency with which the console scans
the associated discrete inputs for the DCD point. When the point is in transition,
the console scans the point once each second regardless of the scan period.
Accumulation Point Tuning
In addition to the information provided on the accumulation faceplate, the
instrument area includes:
„
Integrity bits for the last hour, shift, and day totals
„
Integrity bits for the last hour, shift, and day averages
„
The last hour total and average
„

subsection Console Activity Points on page 5-55 plus
„
The date the batch was started
„
The delay state timer — Displays the amount of time already spent in the delay
state. This field is 0 unless the current state is DELAY, when it increases
incrementally once per minute.
„

„
The failure value
Operating and Tuning Points
5-81
The remote DDPs for activities includes the following items:
„
ITERN LIMIT — The number of iterations for this activity (306).
„
DELAY LIMIT — The delay in minutes of a current delay statement. This is
tunable only if the activity is in the delay state (333).
„
FAIL LEVEL — Fail-level value at which a failure occurs (326).
„
CONT ITER? — The activity executing continuous iterations (YES/NO)
(334).
Other activity DDPs include the acquired point set. The acquired points are tunable.
If the current procedure has a point set, it is included in the DDPs. The remaining
DDPs list grade values.

Chapter 6
Trending
Introduction
This section discusses the PROVOX® Trend View application, one of the software
components of the DeltaV Operate for PROVOX Console user interface. The
PROVOX Trend View application supports real-time trending of process data. There
are two components to trending: collecting trend data and displaying trend data.
At the console trend data is collected and stored as trace data sets on the Console Data
Server. Each trace data set is a combination of tag, attribute (and occurrence, if
necessary), sample interval, and duration (the length of time for which data is stored).
The Trend View application uses trend view files (.ptv files) to determine how trend
data appears when displayed.
Trace Data Sets
The console converts configured trend traces to trace data sets during download. The
console begins collecting data for these trace data sets as soon as the console is
started. You cannot modify or delete trace data sets that the console creates from
configured trend traces.
You can also define trace data sets from the Trend application. Note that a point can
have as many as 12 trace data sets defined for it. You can create multiple traces for the
same attribute at different sample intervals. You can delete the trace data sets added
from the console.
Note that trace data sets that you add are volatile. That is, subsequent downloads that
affect trend sets may delete trace data sets. Also, updating the console software deletes
all trace data sets (though downloading creates trace data sets for all trend traces
configured in the download).
If the download contains multiple instances of a point and attribute combination
configured with more than one sample interval, only two of these traces are converted
into trace data sets. The download order determines which trace definitions are
converted to trace data sets. The download order cannot be determined and may vary
from download to download.
In other words, if a download contains multiple trace definitions for a point and
attribute combination that have different sample intervals and durations, there is no
way to tell which definitions will be converted to trace data sets.

Trend Views
You create trend views, either by importing configured trend sets and saving them as
trend view files or by creating new views. Trend views include information on the
appearance of the trend information at the console. Save the trend views as .ptv files
on the operator station and open and edit the files as desired. Note that manipulating
the trend views (.ptv files) has no effect on the underlying trace data sets.
The Trend Window
The Trend View application displays the values of the Point Attribute Occurrences
over a period of time in a line graph in the Trend Window. The following figure shows
the Trend Window.

Using DeltaV Operate for PROVOX® Consoles
The following are the basic elements of the Trend Window:
„
Main Menu
„
Trace Drawing Area

Main Menu
The main menu has the following options:
„
File — Create a trend view file, open an existing trend view file, import a
configured trend set, save the current trend view, print the trend view, or exit.
„
Edit — Add or delete a trace data set, export a trace’s data to a comma-separatedvalue (.csv) file, acknowledge the alarm horn, and change a trace’s color and scale.
„
View — Define the appearance of the current view, including grid lines, cursor,
and time span.
„
Select — Select one of the traces in the current view.
„
Help — Open the help for the Trend Window.
Trace Area
The Trace Area contains a graph of the data collected over time for each trace
displayed in the Legend. The vertical axis at the right of the trace area shows the
engineering units range for the selected trace. The selected trace is shown as a bold
line in the Trace Area.
Use the Cursor, shown as a dark vertical line, to examine values at any point in the
trend. Move the cursor to desired position and read the trace values in the legend.
Note that because the trend application can display trace data taken at multiple sample
intervals and multiple durations in the same view, the values that plot the traces (and
that appear in the value column of the legend) are always interpolated from the
underlying trace data. If you need to examine the collected values, export the trend
trace to a .csv file.
Toolbar
The toolbar below the trace area contains time fields and several buttons.

Legend
The Legend contains the following information about each of the trace data sets in
the current view:
„
Color — Indicates the color of the trace.
„
Value — The value of the trace at the cursor position. The background color of
the value cell means the following:
•
•
•
White -- Trend is receiving current regular information on the point.
Magenta -- Stale data. The point associated with this trace has reported, but
the attribute and occurrence value had not been updated when it was
expected. It had a previous value, but not the latest update(s) so the data was
suspect.
Gray -- The trace's data is unavailable or data is pending. Data may be
unavailable because the database is unavailable, the data set associated with
the trace has been removed, or you have scrolled back or forward and the
data has not yet been transmitted from the server to update the view.
The last condition should clear in a few seconds. If it does not, try selecting
View | Refresh.
„
Point Tag — The configured tag for the point.
„
Attribute — The attribute (and occurrence, if required) whose data is being
viewed.
„
Description — The configured description of the point.
„
Scale — The high and low limits of the trace.
„
Sample Rate — The interval between data samples for this trace.
„
Duration — The length of time for which data is saved for this trace.
Importing Configured Trend Sets
You can import configured trend sets and save them as Trend View files (*.ptv). To
import a configured trend set perform the following steps:
1. Select File | Import from the Main menu in the Trend window.

Adding A Trace Data Set
The pane at the right of the dialog contains the valid trendable attributes for the
currently selected point. As you select an attribute it appears in the field above the list.
If an attribute has multiple occurrences, you must edit the occurrence in that field if
you want to use anything other than occurrence 0.
After you edit the occurrence, if necessary, set the duration and sample interval and
click OK to transfer the tag, attribute, occurrence, duration, and interval to the Traces
pane of the Point Trace Data Sets dialog. Note that attributes with multiple
occurrence numbers do not include the occurrence number for occurrence 0. For

a traces list:
„
TRACKING @ 15 Seconds ^ 4 Hours
„
TRACKING[1] @ 15 Seconds ^ 4 Hours
„
TRACKING[2] @ 15 Seconds ^ 4 Hours
You can add a trace to a trend view by selecting it in the Point Trace Data Sets dialog
and clicking the OK button.
Each point can have as many as 12 trace data sets defined for it. They can be any
combination of configured traces and trace data sets added online.
You can create more than one trace for a point, attribute, and occurrence
combination.
Removing Trace Data Sets
To remove a trace data set, select it in the Traces pane of the Point Trace Data Sets
dialog and click the Remove button. A confirmation dialog appears. Click OK to
remove the trace data set. If the trace data set is from a configured trend set, an error
message appears.
Note
You cannot remove a configured trace data set nor can you edit the sample interval or
duration of a configured trace data set.
Viewing Trends
After you import a trend set or create a trend view, you can open a trend view by
selecting File | Open from the Trend Viewer. The software presents a dialog from
which you can select an existing trend view (.ptv file).
After the view file is open you can manipulate the view in a variety of ways: adding
grids, adding a legend, and so on.
Note
Viewing trace data sets collected at small sample intervals with the time span set to a
large duration may mask some short duration events.
The Trend Viewer creates a trace by computing an interval at which to extract trace
values from the trace data. The computed interval is based on the trace data set's
sample interval and the trend view's time span and current window size. If the
duration of an event is less than the computed interval, it is possible that the event will
not appear in the view.
Trending
6-9
If data becomes unavailable for a trace data set, there are some indications in the
Trend Viewer. The trace will not appear if the trace data is unavailable. If you use the
cursor to check the trace value, the value field is blank for the trace if data is
unavailable.
Exporting Trace Data
You can export the selected trace's data to a comma-separated-value (.csv) file by
selecting Edit | Export. You are prompted for a file name. After you enter a file name
the trace data is saved into a file containing all the available data for the trace.
Under some circumstances a message may appear indicating that some of the data was
pending and that you should export the data again. This occurs because it takes a
finite amount of time to transmit all of the data for a trace from the Console Data
Server to the operator station.
The exported .csv file contains a header line followed by one line of data for each
sample. The header line indicates the fields on each data line: Date, Time, Value, and
Status. The Status field usually contains either Good or Stale, but can also contain
Extrapolated, meaning the values in these fields were based on surrounding values and
not collected.
Note
6-10
Exported data in the .csv file is in reverse order by time. That is, the newest values are
at the top of the list. Sort the data on the TIME field before creating a chart from the
data.

Event Journal
Introduction
This section explains how the PROVOX® Event Journal spools messages and
events—alarm messages, OAR messages, operator actions, and general system
events—and the two ways you can use the Event Journal to view them: the CSV view
and the optional database view.
Though the instructions in this section are specific to using the Event Journal from an
operator station, you can access the Event Journal from any computer with Internet
Explorer 5.0 or greater installed as long as the computer can communicate with the
Console Data Server.
Message Spooling
Instead of logging messages to a printer the DeltaV Operate for PROVOX Console
saves alarm messages, Operator Action Requests, operator actions, and general
system events on the Console Data Server hard disk as comma separated value (.csv)
files. The files have names in the form:
2010-03-21-14.csv
In the file name 2010-03-21 is the date and 14 is the number of hours past midnight
UTC (Coordinated Universal Time) at which the file was created. The server creates a
new file every hour.
The first line in each file contains header text for all the columns in the file. This line is
useful if you import the csv file into a spreadsheet.
Each remaining line in the .csv file is a record corresponding to a console event. The
records are logged in the order received.
Note
Under some circumstances it is possible for operator change messages to be logged after
the message verifying the operator change.
Each record has a unique identifying number and contains more than 200 fields,
though most records use a small subset of the fields. The second column of the .csv
file is the MsgId column. Each message type has a different Message ID. You can use
the information in the Message ID column to search for specific types of information
in .csv files.
Event Journal
7-1
The .csv files reside on the Console Data Server. The default location for the .csv files
is in the \POC\Spooler directory. You can view the .csv files from the server or copy
them to other machines for further processing or analysis.
You can import the .csv files into tools such as Microsoft Excel for analysis.
Event Journal CSV View
Use the Event Journal included in the console software to navigate through and view
the comma separated value (.csv) files the console creates. The following figure shows
the Event Journal CSV view.

Alarm Management
With the DeltaV Operate for PROVOX® software you have a choice on how to
process and display PROVOX alarms:
„
You can use DeltaV-style alarm processing and have the alarm banner contain all
PROVOX and DeltaV alarms sorted by importance.
„
You can continue to use PROVOX alarm processing and have two alarm banners,
one for DeltaV alarms and one for PROVOX alarms.
DeltaV-style Alarm Processing
This section gives an overview of how to set up the DeltaV Operate for PROVOX
software to process alarms in the DeltaV style. For more information on DeltaV
alarms, refer to the section Alarms and Events Overview in the DeltaV Books Online.
To enable DeltaV-style alarm processing:
1. Open the Alarms tab of the DeltaV Operate for PROVOX properties from the
Console Data Server.
2. Select the DeltaV style alarm processing check box.
3. Close the dialog.
Note
Note: A total download or restart is required for a change in the alarm processing to
take effect.
4. Refer to the Getting Started manual for information on setting up the combined
alarm banner.
Enabling DeltaV-style alarm processing in the Console Data Server causes the
following changes in alarm processing:
Alarm Management
„
Alarms have a single priority (the configured Active Unacknowledged priority)
„
Unacknowledged alarms have a higher importance than acknowledged alarms.
„
After the acknowledgement status is considered, alarms that are still active are
given a higher importance than alarms that have already cleared but have not been
acknowledged by the operator.
„
When more than one alarm has the same acknowledgement status and active
status, alarms with higher priority values have higher importance.
8-1
„
When more than one alarm has the same priority value, active status, and
acknowledgement status, the newer alarm has a higher importance.
„
Alarm colors in the alarm banner are defined by DeltaV alarming. PROVOX
faceplates, the Instrument Area, and the PROVOX alarm summary continue to
use PROVOX alarm colors.
PROVOX Alarm Processing
The console can display as many as four alarms for each point. Some points use all of
the alarms and other points use none. Some points, such as AI and Loop points can
be configured to have four additional alarms.
For example, in a 10,000-point instrumentation system each point may have several
alarms. The configuration engineer configures many of these alarms to appear at the
console, and some of them to sound the console horn or external audible alarms. In
such a situation, you could become overwhelmed with alarms, many of which may be
irrelevant to the current situation.
Alarms may be irrelevant for two reasons. First, the alarms’ significance may change
depending on what is happening in the process. Second, even in smaller systems, you
may only be responsible for part of the process. The console overcomes many of
these problems by providing only the information that is relevant to you. For
example:
„
You or the configuration engineer can change each alarm’s characteristics based
on the operational state of the related equipment.
„
Password restrictions can limit access to parts of the process so that the console
supplies alarm data based on each operator’s responsibilities.
The console’s alarm management features improve your effectiveness by providing
only the alarm information that is relevant to you. Features that help you manage
alarms include:
8-2
„
Alarm Priority Definitions — Sets of alarm characteristics PPAs use to handle
alarms.
„
Plant Process Areas (PPAs) — A console-based management point that
determines which alarm priority definitions the point alarms use.
„
Plant Management Areas (PMAs) — A console-based management point that
has one or more PPAs reporting to it. A PMA assigns points to consoles and
controls access.
„
Alarm Area — A list of current alarms (based on user privilege) displayed at all
times, sorted by priority.
Using DeltaV Operate for PROVOX® Consoles
PPAs and PMAs form the basis of an alarm hierarchy. The following figure illustrates
the relationship between points, PPAs, and PMAs using a typical example.
Figure 8-1
Example Of The Relationship Between PMAs and PPAs
Alarm Priority Definitions
Alarm priority definitions determine the alarm characteristics for groups of related
alarms. The characteristics of an alarm determine how it communicates with you.
Alarm characteristics can, for example, cause an alarm to sound the console horn,
appear in the Event Journal, and flash at the screen.
During console configuration, the configuration engineer creates alarm priority
definitions. For example, the configuration engineer might name the highest-priority
alarms CRITICAL. CRITICAL alarms would be the most visible alarms. In defining
CRITICAL alarms, the configuration engineer would assign numbers from 1 through
12—with 12 being the highest priority—to various characteristics, for example:
Alarm Management
8-3
When the alarm is...
„
Active and has not been acknowledged by the operator, priority = 12
„
Inactive and has not been acknowledged, priority = 8
„
Active and has been acknowledged, priority = 4
In addition, the configuration engineer can define characteristics such as
acknowledgment and colors of the critical alarms. For example:
„
Alarm displayed? YES
„
Acknowledge active alarms automatically? NO
„
Acknowledge inactive alarms automatically? NO
„
Sound the horn? YES
„
Log at the logging unit when alarm activated? YES
„
Log at the logging unit when alarm deactivated? YES
„
What color is the alarm word when the alarm is active and unacknowledged?
Blinking white on red
„
What color is the alarm word when the alarm is active and acknowledged? White
on red
„
What color is the alarm word for an inactive, unacknowledged alarm? Cyan on
black
A level loop deviation alarm in a tank may require the CRITICAL alarm priority
definition in the example above because, if the level in the tank deviates beyond the
configured limits, it may ruin the product or endanger plant personnel. However, the
loop’s deviation alarm requires CRITICAL characteristics only during normal
operations. During a shutdown period, plant personnel expect level deviation.
In this example, the point deviation alarm requires different characteristics (for
example, lower priority, less visibility) during a shutdown period through a different
alarm priority definition. An operator with PPA CHANGE privilege can change
point characteristics as process conditions change by accessing PPAs and changing
the PPA operational state.
The configuration engineer defines as many alarm priorities as necessary to handle
each situation.
8-4
Using DeltaV Operate for PROVOX® Consoles
Understanding Alarm Strategies
Alarm management is a strategy that allows the operator to interact with the process
control system. Through this strategy, the control system detects and annunciates
abnormal process conditions so that operators can take corrective action.
To be effective, the alarm information you receive needs to be prioritized in such a
way that:
„
Related alarms are combined
„
Alarms are divided between several operator stations on a process-grouping basis
In continuous processing operations, alarm management often resembles a controlby-exception strategy. With this philosophy, you can expect normal operations to
continue for relatively long periods of time because the process is relatively stable.
Alarms sound only when the process deviates and develops abnormalities.
In batch processing operations, alarms are the main tool for annunciating abnormal
events within the process, even though you receive process updates regularly through
step change messages, Operator Action Requests, and other display information.
Plant Process Areas (PPAs)
A configuration engineer assigns the points for a related group of process equipment
to a single PPA because these points support common process operations and have
related alarm requirements. A PPA is a console-based management point. The PPA
determines which alarm priority definitions are used for which points.
PPAs have two main components that determine which alarm priority definitions are
used for their related points’ alarms:
„
Operational states
„
Alarm groups
Operational States
The configuration engineer defines operational states for equipment associated with
each PPA. NORMAL, SHUTDOWN, and MAX-THRUPUT are examples of
possible operational state names. The configuration engineer defines as many as five
operational states for each PPA.
Operators with PPA change privileges can change the operational state of each PPA
as the process changes. The Computer/Highway Interface Package (CHIP) and the
Alarm Management
8-5
20-Series (SR90) unit operations controllers (UOC) and integrated function
controllers (IFC) can also change the operational state of PPAs.
Alarm Groups
The configuration engineer defines as many as seven alarm groups for each PPA.
Each point alarm in the PPA is assigned to one of these groups. An alarm group
would contain all of the point alarms in the PPA that require the same alarm
characteristics for the PPA operational states.
Alarm Group Definition
Together, the alarm groups and the operational states form a table that determines the
alarm priority definition, and therefore the alarm characteristics, for each point alarm
in the PPA. The following table is an example of such a table, called the alarm group
definition. It shows the alarm priority definitions used for the NORMAL,
SHUTDOWN, and MAX-THRUPUT operational states.
Table 8-1 Alarm Group Definition Example
Alarm Group

Operational States (as many as 5)
Shutdown
Normal
Max-Thruput
1
NORMAL
NORMAL
NORMAL
2
IGNORE
NORMAL
NORMAL
3
NORMAL
NORMAL
CRITICAL
These operational state names are only examples; the configuration engineer creates
the operational state names for your PPAs, and each can be different. Note that the
alarms in different alarm groups have different characteristics as you change the PPA’s
operational state from normal to shutdown, and so on. For example, during
shutdown, alarms in alarm group 1 have NORMAL characteristics, while those in
alarm group 2 have IGNORE characteristics.
PPA Critical Level
The PPA’s critical level determines whether the point name or the PPA name appears
in the alarm area. The alarm area contains:
8-6
„
Point tags with the highest priority alarms
„
PPAs containing the highest priority alarms
Using DeltaV Operate for PROVOX® Consoles
It can also display combinations of both. These are based on the PPA critical level.
The critical level is a priority fence with larger numbers indicating higher priorities.
Alarms with a priority equal to or above the PPA critical level appear in the alarm area
by point name. If the alarm’s priority is below the associated PPA’s critical level, the
PPA name appears in the alarm area instead of the associated point name.
For example, in a particular instrumentation system there are three current alarms
associated with PPA07. If all the alarms associated with PPA07 have a priority number
that is lower than PPA07’s critical level, the console displays PPA07 in the alarm area.
However, if all the alarms associated with PPA07 have priority numbers that are equal
to or greater than PPA07’s critical level, the three point names for the alarms appear in
the alarm area. If only one alarm is above the PPA critical level, the alarm area displays
the point name for that alarm. The PPA name is displayed for the other two alarms.
The point or PPA names in the alarm area appear in the colors of the highest-priority
alarm for the point or PPA.
As with the PPA operational state, you adjust a PPA’s critical level if you have the PPA
change privilege associated with your password. The critical level allows you to change
the items in the alarm area dramatically. For instance, you can raise the critical level of
a PPA that has several of the highest-priority alarms. By doing so, you remove the
point names from the alarm area and add the PPA name. The following figure shows
an example of the PPA instrument area.
Alarm Management
8-7
Figure 8-2
PPA Instrument Area
PPA Tracking
If so configured, all console electronics units in an instrumentation system track the
critical level and operational state of the configured PPAs. When a console receives a
request to change a PPA’s critical level or operational state, it sends this information to
other participating consoles so that they can update their databases.
8-8
Using DeltaV Operate for PROVOX® Consoles
A participating console is one that has been configured so that PPA TRACKING is
YES. This feature ensures that each console uses the same PPA operational state and
critical level. As many as 50 consoles can track the PPAs in an instrumentation system.
PPA Operation
The PPA instrument area is the user interface for PPAs. Through a PPA, if your
privilege levels permit, you can:
„
Select the alarm display for each of the highest-priority alarms in the PPA.
„
Change the operational state of the PPA.
„
Change the critical level of the PPA.
To access one of the highest priority alarms for a PPA click on the point name in the
list of points. The configured alarm display, if any, appears in the graphics display area
and the point's controls appear in the Instrument Area.
To change a PPA’s operational state click on the OP STATE menu button. A menu of
the operational states available appears. Click on the desired state.
To change a PPA’s critical level, enter the desired critical level in the entry field.
Plant Management Areas (PMAs)
PMAs group PPAs together according to your job responsibilities. Typically, one
operator would be responsible for the process within one or more PMAs.
Note
Through configuration, a single PPA can be associated with several PMAs
With PMAs, you control only certain PMAs, PPAs, and points based on privileges
assigned to your password. This hierarchy limits access to certain process areas for
security purposes. In addition, you can change the way the PMA’s associated points
report their alarm data and reporting mode simply by changing the PMA mode.
PMA Modes
The PMA mode determines the reporting and alarming modes for the PMA’s
associated points. It overrides some of the alarm characteristics defined by PPAs.
The four PMA modes are: ON, BACKUP, MONITOR, and OFF. When a PPA is in
more than one PMA, the PPA uses the highest priority PMA mode in order of priority
(ON, BACKUP, MONITOR, OFF).
Alarm Management
8-9
You can change a PMA mode if you have the CHANGE PMA privilege for that
PMA. The following table shows how the reporting mode and the alarming mode
change based on the PMA mode. The next two subsections define the alarming and
reporting modes listed in the table.

Reporting Mode Definitions
The reporting modes affect the way points report data as follows:
„
CONFIGURED — Points report based on their configured point definition:
periodic, exception, or change of state.
„
CHANGE OF STATE — Points report when their alarm status changes, or
when one of their discrete inputs changes state.
„
BACKGROUND — Points do not report unless you activate the point by
displaying its controls in an instrument area or one of the point attributes is in a
real-time trend.
The devices that contain points in background mode send null-packet messages to the
requesting device every 15 seconds to verify continued operation. Background
reporting greatly reduces data highway and chip loading for points that can be
activated and deactivated as required.
Alarming Mode Definitions
The alarming modes affect the alarm characteristics as follows:
8-10
„
CONFIGURED — The associated PPA’s alarm group definition determines
the alarm characteristics.
„
MUTE — The console automatically acknowledges the alarms, disables the
horn, and stops the logging unit from logging the alarm, but the console still
Using DeltaV Operate for PROVOX® Consoles
displays the alarms in the alarm area. Priority and color characteristics remain as
defined by the associated PPA’s alarm group definition.
„
OFF — The console does not display alarms in the alarm area line and does not
report them except when you call up a display containing that alarm. When the
display appears, the alarms are muted and are not displayed in the alarm area. (The
alarm summary sorted by time still shows a list of all console alarms.)
PMA Access
Your password provides privilege levels. Privilege levels determine the console
operations you may perform. The privilege levels available are TUNE, OPERATE,
ACCESS, LOCK, and DOWNLOAD. Refer to Appendix A for a list of the
operations allowed for each privilege level.
Your password includes a base privilege level that applies to all points in the console.
Also, your password can include additional privileges for each PMA. The privilege
level the configuration engineer assigns to a PMA determines the operations you can
perform on the points associated with that PMA. For example, you may be able to
operate the boilers but not he main plant. Another operator may have the privilege to
operate the main plant, but not the boilers. The engineer may have the privilege to
operate and tune everything.
CHANGE PPA and CHANGE PMA are additional privilege levels that can be added
to ACCESS, OPERATE, and TUNE privileges, and allow modifying the reporting
and alarming parameters of PPAs and PMAs. The privileges can be assigned as a base
or global privilege for all PMAs and PPAs or for selected PMAs. The following figure
shows a PMA instrument area.
Alarm Management

„
Select one of the associated PPAs that contains one or more points in alarm. Each
PPA carries the number and color of the point with the highest priority alarm.
„
Change the PMA mode.
Using DeltaV Operate for PROVOX® Consoles
To select the alarm display for a PPA or point with a high-priority alarm click on the
PPA name in the list of PPAs. The alarm display configured for the PPA appears in
the graphics display area and the PPA controls appear in the instrument area. If the
PPA does not have an alarm display configured, the console draws the alarm display
for the point in the PPA with the highest-priority alarm, if configured.
To change a PMA’s mode click on the PMA MODE menu button. A menu of the
modes available appears. Click on the desired mode.
Station Independent Alarming
To further improve your effectiveness in managing alarm strategies, the console
software has an additional alarm management feature known as station independent
alarming. This feature is designed to eliminate alarms that occur outside your area of
responsibility. The feature enables each station to have alarm annunciation
independent of other stations on the same console electronics.
Station independent alarming limits alarm information so that you:
„
See only alarms for points that are in PMAs for which you have OPERATE or
TUNE privilege.
„
See on the alarm summary by priority only those points that are in PMAs for
which you have OPERATE or TUNE privilege.
„
Hear the horn only for points that are in PMAs for which you have OPERATE
or TUNE privilege.
You still see all system alarms in the alarm summary by time and in alarm blocks on
faceplates.
Acknowledging Alarms and Horns
How you acknowledge alarms and horns depends on how your process and console
have been configured.
Global Alarm Acknowledgement
For you to be able to acknowledge alarms globally, the console must have been
configured as a part of a PPA tracking ring. If the console you are using is not in a PPA
tracking ring (PPA tracking is not enabled), it cannot send or receive Global Alarm
Ack messages.
Alarm Management
8-13
If the configuration supports it, you can acknowledge system alarms on other
consoles from a single console. You can acknowledge one or more alarms once for all
consoles in a PPA tracking ring. Operator Workplace and PROVUE® consoles can
work together in the same tracking ring.
If the configuration engineer has enabled global alarm acknowledgment during
console configuration, you acknowledge system alarms by clicking on the Ack Alarm
button. After you acknowledge alarms, a list of highway access numbers of points
being acknowledged goes into a data highway message. Only those points that are
valid in the tracking ring appear in this message, and the console acknowledges alarms
only for those points you have privilege to operate.
The system acknowledges these alarms at the requesting console first. The message
then gets forwarded to the next console in ascending address order, until all consoles
have been notified that the alarms are acknowledged.
Local Area Horn Acknowledgement
For local area horn acknowledgement to work, the console must have been
configured as a part of a PPA tracking ring. If the console is not in a PPA tracking ring
(PPA tracking is not enabled), it cannot send or receive Local Area Horn Ack
messages.
You can acknowledge all horns for consoles in a PPA tracking ring on the same
highway from a single console, if the feature has been enabled during configuration.
This allows a single operator to acknowledge one horn once for all consoles on the
same highway in a PPA tracking ring.
Acknowledge system horns by clicking on the Silence Horn button on the DeltaV
alarm banner. Once you do this, a highway message is formatted to include the station
number the acknowledgement was requested from.
The PROVOX® system acknowledges horns at the requesting console first. The
message then gets forwarded to the next console in ascending address order, until all
consoles have been notified that the horns are acknowledged.

Generating and Downloading
Introduction
This section addresses the following subjects:
„
Generating the configuration
„
Downloading the configuration to the console
Generating
There is no change in the ENVOX® or Control Desktop generate utility for the
console.
However, before you generate the configuration, make sure that your operator
stations are defined as users or at least that you have defined an ANYNODE user.
Also make sure that the DeltaV users defined in the operator stations are included as
users in the PROVOX® configuration.
Note
Before you log on the console must be downloaded with a configuration that defines
operator stations as users or defines the ANYNODE user. If neither of these conditions
is met, you will not have any console privileges. If you are using the default installation
you will be unable to exit from the console software.
If you download a configuration that does not include workstation usernames or the
ANYNODE user, to recover you must delete the download (.dwn) and download
image (.img) files from the server's hard disk and download a corrected configuration.
To delete the files:
1. Open the Windows Services application.
2. Select POC Base in the Services dialog list
3. Click the Stop button
4. Click the Yes button on the confirmation dialog.
After a few moments the POC Base service stops.
5. Delete the .img and .dwn files in the \POC\CFG directory.
6. Restart the computer (recommended as a precaution)
7. Download a configuration that includes workstations defined as users.
Generating and Downloading
9-1
If your configuration is defined for an Operator Workplace Console (WPCON to the
ENVOX software) Revision P1.2, generate the configuration as described in the
configuration software documentation.
Downloading
This subsection explains the two methods of downloading a configuration to the
console: total and partial.
The console software accepts downloads configured for Operator Workplace
Consoles, revision P1.2 — both total and partial downloads, and both continuous and
batch configurations.
Graphics displays must be configured using DeltaV Operate's Configure mode.
PROVOX displays in ENVOX downloads will be accepted, but ignored by the
DeltaV Operator Station. Removing unneeded and unused PROVOX displays from
the download reduces the download time dramatically.
Total Downloading
Total downloading supplies the console with all the information in the console
configuration.
Once you start the download, you monitor and control the download in phases.
During a total download, the console sends messages to the message log to provide
status information on the download.
The phases of a total download are:
„
Transfer
„
Configuration update
The transfer phase begins when you initiate the total download from the
configuration software.
The following paragraphs describe the phases in detail, and explain how to start and
monitor each phase.
Transfer
During the transfer phase, the configuration device transmits the download files to
the console. You do not need to take any action during the transfer.
The console’s integrity display includes a field which indicates what type of download,
if any, is pending
9-2
Using DeltaV Operate for PROVOX® Consoles
Note
When downloading to a redundant console pair, do not perform the configuration update
phase until the configuration has been downloaded to both the consoles in the redundant
pair. This minimizes the time that the consoles must operate with different
configurations.
The download files are always saved to the hard disk. The hard disk holds the
download files until an operator with DOWNLOAD privilege requests a
configuration update. The console remains fully functional during the transfer phase,
and the transfer phase does not affect the on-line console database.
Configuration Update
If the console is in the Idle state, it automatically begins the configuration update
when the transfer completes. Otherwise, the configuration update must be requested.
To update the configuration:
1. Log on to the PROVOX software as a user with DOWNLOAD privilege.
How you do this depends on whether you are at a Server or Operator
Workstation and whether your installation has secure common logons
implemented. Refer to Chapter 5 of this manual for a discussion of secure
common logins.
2. Start the Database Update utility, either by navigating to DeltaV Operate for
PROVOX | Engineering | Database Update from the Start menu, or by clicking
the icon on the toolbar (on Operator Workstations only). You can also start a
database update from the Instrument Area on an Operator Workstation.
3. Click on the Update Database button in the dialog. This completes the
configuration update operations.
During the update the console replaces all the configured database elements with the
total download data during a configuration update. During this time, all windows
remain open and existing data remains. Access to new information may be deferred or
denied until the update is complete. After a total download configuration update, the
console begins processing without any old console-based process data.
Note that after a download update a message is spooled to the Event Journal that says
the NONE operator was logged on to the Console Data Server.
Partial Downloading
A partial download alters an existing console database by changing or deleting a
limited number of original database elements, or by adding new elements to the
Generating and Downloading
9-3
original database. The console remains completely functional during the partial
download.
After you start the download, you monitor and control the download in phases.
The phases of a partial download are:
„
Transfer
„
Configuration update
„
Database compress (as required)
The transfer phase begins when you start the partial download. The configuration
update and database compress phases require console-operator action. The following
paragraphs describe the phases in detail, and explain how you start and monitor each
phase.
Transfer
During the transfer phase, the configuration device transmits the download files to
the console.
In the transfer phase of a partial download, the configuration device transmits the
download files to the available configuration space (free RAM). The free RAM holds
the download files. The console remains completely functional during the entire
transfer and the transfer does not affect the on-line database. The console also saves
the partial download to the disk.
The following messages appear in the log:
Partial Download being Saved to disk from @(highway address)
Partial download from @(highway address) has been saved to disk
Partial Configuration Download Save in Progress : ID = (number)
Partial Configuration Download Saved - Awaiting Configuration Update
You do not need to do anything during the transfer. After the transfer is complete
start the configuration update.
After a successful transfer the following message appears in the integrity display for
the server:
Partial Pending ID = (number)
Note
When downloading a redundant console pair, do not proceed to the configuration update
phase until you transfer the partial download to both consoles in the redundant pair. This
minimizes the time that the consoles must operate with different configurations.
Configuration Update
9-4
Using DeltaV Operate for PROVOX® Consoles
After the new data transfers to the hard disk or user-configuration space, you update
the configuration by moving the transferred data to the on-line database.
To update the configuration of a console:
1. Log on to the PROVOX software as a user with DOWNLOAD privilege.
How you do this depends on whether you are at a Server or Operator
Workstation and whether your installation has secure common logons
implemented. Refer to Chapter 5 of this manual for a discussion of secure
common logins.
2. Start the Database Update utility, either by navigating to DeltaV Operate for
PROVOX | Engineering | Database Update from the Start menu, or by clicking
the icon on the toolbar (on Operator Workstations only). You can also start a
database update from the Instrument Area on an Operator Workstation.
3. Click on the Update Database button in the dialog. This completes the
configuration update operations.
The console replaces, changes, adds, and deletes data in the database, as appropriate.
This update can change a single parameter for a single point, or it may alter nearly
every element in the database. A typical partial download update for a 1500-point
console takes only 15 to 30 seconds. During this time, windows remain open but
access is hampered.
After a partial download configuration update, the console processes much of the
process data received during the configuration update. This data includes alarm
information, operating parameters, print requests, and so on.
Database Compress
A configuration update of a partial download can fragment the total unused memory
space in the console database into units too small to be useful. Thus, the console
could reject future partial downloads because the fragmented database could not
accommodate the data from the partial download.
You can compress the existing database in order to make a single, larger block of free
memory space available. The database compress phase is not always necessary prior to
a successful partial download.
If the database needs to be compressed, the Database Update dialog includes the
following message in the Pending Database Operation field:
Database is fragmented, compress suggested
To compress the database, click the Compress Database button.

Appendix A Console Access and Privileges
Introduction
In the PROVOX® Operator Console, workstations must be configured with the
ENVOX® or Control Desktop software as users, or the special user ANYNODE
must be configured in the console download.
Note
Operator stations must be defined as users or the ANYNODE user must be defined
in configurations downloaded to consoles or users will not have any privileges after logging
in to the console software.
The workstation or ANYNODE must have DOWNLOAD privilege or you will not
be able to download to the console.
Your access to console functions at an operator station is determined by the most
restrictive of:
„
The configured privilege level of the workstation you are using.
„
Your configured privilege level.
For example, operator Sam with a base privilege of OPERATE is logged on to the
operator station CONSOLE2. CONSOLE2 is configured as a user with TUNE
privilege. However, operator Sam has only OPERATE privilege so he cannot tune
any points.
Engineer Joe, whose base privilege is TUNE, needs to tune a point. He logs on to
CONSOLE2. Because both Joe and CONSOLE2 have TUNE privilege, Joe can tune
the point.
The plant also has an operator station named DEMO1 that is not configured as a
user. The ANYNODE user has been configured with OPERATE privilege, however,
so that privilege applies to DEMO1. If engineer Joe had logged on to DEMO1, he
would not be able to tune the point as his TUNE privilege would not be able to
overcome the more restricted access of the ANYNODE user definition.
Console Access and Privileges
A-1
Privilege Levels
Ultimately controlling your ability to perform process control functions at the
operator station is your privilege level that was defined during console configuration.
Privileges may be granted for all PMAs or for selected PMAs only. The privileges are:
„
DOWNLOAD — permits you to download the console and to have access to
the console’s Utilities functionality. You are not permitted access to displays or
operating and tuning data.
The DOWNLOAD privilege is identified in the tables below by the letter D.
„
LOCK — permits access to the console’s Help and Utilities functions only. You
are not permitted access to displays or operating and tuning data.
The LOCK privilege is identified in the tables below by the letter L.
„
ACCESS — permits access to the console’s Help and Utilities functionality as
well as the ability to view displays. You are not permitted to change any operating
or tuning data.
The ACCESS privilege is identified in the tables below by the letter A.
„
OPERATE — permits access to the console’s Help and Utilities functionality as
well as the ability to view displays, change operating data, and execute utility
procedures. You are not permitted to change any tuning data.
The OPERATE privilege is identified in the tables below by the letter O.
„
TUNE — permits access to the console’s Help and Utilities functionality as well
as the ability to view displays, change operating data, execute utility procedures,
and change tuning data.
The TUNE privilege is identified in the tables below by the letter T.
If your privilege is insufficient to perform a function, the button or menu selection for
that function is insensitive (does not respond to input) and appears faded.

Appendix B Valid Modes and Inputs for Point Types
Introduction
The table in this chapter shows the valid modes and allowable input for each point
type. The table shows the modes the console can send for each point type. The modes
that devices will accept may be different.
Note
If you enter a numeric value, the allowable range for most points is -128% to 127% of
the engineering units (EU) for the point. For a PDO or PDM point, the allowable
range is 0% to 100% of the engineering unit range. The console transmits range values
of 0% and 100% to the device as 0 and 65,535, respectiviely.
If the number resulting from the conversion of an engineering unit value to a number
between 0 and 65,535 has a fraction, round it off. Fractions equal to or greater than
0.5, round off to the next larger whole number. Fractions less than 0.5, round off to the
next smaller number.
There are several types of input:
„
value — enter a number as explained in the note.
„
slew — click and hold on a directional arrow or use the slider to set the value.
„
text — enter as many as 80 characters.
„
menu button — use the menu button to select a value.
„
toggle button — click on the button that represents the desired value.

Appendix C Auto Parameter Select
Points and Modes
If Automatic Parameter Select has been configured, when you move a point’s controls
to the instrument area, input focus may be on a particular control, depending on the
point type and point mode. This appendix lists point operating parameters that have
input focus for points. If a point is not in MAN or AUTO mode, the console does not
give input focus to any parameter.
Note that Auto Parameter Select applies only to the Instrument Area and not to the
PROVOX faceplates.
