a. S – Service. Means that the web interface is automatically generated in XBuilder and only contains values
in value pages and is aimed for commissioning and service. It is not possible to have any end-user web
content, such as graphics, trend viewers, alarm viewers or value pages.
T – Time Object Pages. Means that Time Object Pages can be added to the XBuilder project. These will
only appear for Xenta Servers 701/721 in TAC Vista Workstation and can be used to control Xenta Server
time charts from Vista Workstation
C – Custom. Means that the web interface is totally configurable in XBuilder; navigation and all features
for creating a full end-user web are available.
b. Xenta Supp. – Xenta 280/300/401 support. Means that Xenta 280/300/401 can be installed on the LonWorks network beneath a Xenta 700 and are fully supported by both the Xenta 700 and TAC Vista on top
of Xenta 700.
c. The OP7 operator panel mirrors most of the web contents of Xenta 711/731 (‘C’), but also the simulated
web contents of Xenta 701/721, as the OP contents is designed in the same way for Xenta 701/721.
d. The Xenta 913 also supports BacNet, M-Bus, and C-Bus.

TAC Xenta Server – Controller, Technical Manual
The Example
The Xenta Server, in the example, a Xenta 731 includes a controller.
The existing Xenta 401 device for the roof top unit RTU4 is replaced
and a control application to execute the same control functions is created to be executed in the Xenta Server together with Xenta I/O modules.
Note
•
Although the Xenta Server described in this manual is a
Xenta 731, a Xenta 711 could also be used for this purpose.
The other LonWorks devices in the building are connected to the LonWorks network beneath the Xenta 731.
The Xenta 731 (called Xenta_Server_A) also includes a presentation
system that can be accessed using a web browser anywhere on the network, or an OP7 operator panel, connected to the Xenta 731.
For more information on how to create the presentation web, see the
TAC Xenta Server – Web Server, Technical Manual.
Important
•
The functionality to design a customized presentation web is not
available in two types of Xenta Servers:
•
Xenta 701 and
•
Xenta 721
However, pages for the OP7 operator panel can be created in the
same way as the web pages for the Xenta 711/731.

TAC Xenta Server – Controller, Technical Manual
The LonWorks Network Structure
The LonWorks network structure is created in TAC Vista and is called
ACME_Inc after the company. Since the building has two floors, the
network is originally designed with its devices divided into two Xenta
groups named 1st_Floor and 2nd_Floor. Devices located on the first
floor belong to the Xenta group 1st_Floor. The Xenta 104 and the
energy meter are members of the LonWorks group 1st_Floor_LW.
With the control application running in the Xenta 731, there is no longer
a Xenta 401 for the RTU4. Therefore, the Xenta group 2nd_Floor is no
longer required.
The Xenta 731 is connected to Vista via a Local Area Network or alternatively a Wide Area Network using the TCP/IP protocol.

All the devices on the LonWorks network are connected to the LonWorks port on the Xenta 731. All signal values, trend logs, alarms and
so on are handled by the Xenta 731 and the data is sent to and from Vista
across the IP network.
The Xenta 731 also includes a presentation of the ACME building that
allows users to operate the system.
The design for web access is detailed in the TAC Xenta Server – Web

The Project Folder and Folder Structure on the Hard Disk
A project for a complete system is best placed in a directory containing
the folders and subfolders similar to the figure below.
Fig. 2.5: The folder structure on the hard disk.
This structure should be prepared when the device structure of the
project is created, as described in Classic Networks, Technical Manual
or LNS Networks, Technical Manual. The whole structure, or parts of it,
should be in place at this point.
In the text that follows, we use C:\ProjectACME as the project folder.
The Vista database (containing the network structure) requires a folder
of its own. The folder is a subfolder to ProjectACME, and it is called
VistaDb.
A short description follows of the intended use for the folders and their
contents:
•
DeviceDescr – .mta files and .xif files for the LonWorks devices.
•
Documentation – general information, for example, manuals, data
sheets, functional descriptions, I/O lists and so on.
•
VistaDb – the Vista database.
•
Graphics – .tgml files (graphics) for the Xenta Server created
using TAC Graphics Editor, which can be made already before the
XBuilder project is made.
•
BackupLM – backup files of the LonMaker database, in case an
LNS network is in use (not included in Fig. 2.5).

XBuilder is the programming tool used to program the control application for the Xenta server.
References to signals are prepared in a structure for future use on web
pages.
TAC Menta
The Menta programming tool is used when new Menta block diagrams
are needed.
The Xenta 731 will replace the Xenta Server, previously used in the
original ACME Inc. network
The LonWorks network is already configured in Vista and is made
available in Vista through the Xenta Server.
The Xenta device for RTU4 is removed and the control application is
executed in the Xenta 731.

Preparatory Work in TAC Vista
Creating the Xenta Server and connecting the LonWorks network is
performed in Vista Workstation.
For detailed instructions see the TAC Xenta Server – TAC Networks,
Technical Manual.
As the control application will be executed in the Xenta Server, this
example describes how to remove the existing Xenta 401 from the LonWorks network.
3.1
Removing an Existing TAC Xenta Device from the
LonWorks Network
The application for RTU4 in the ACME installation will be executed in
the Xenta Server instead of the Xenta 401.
As the LonWorks network and the device structure are created in
TAC Vista, you use Vista Workstation to make necessary changes.
In our example, the device you want to remove the Xenta 400 for the
RTU4.
Tip

Note
•
3.2
As the Xenta 400 in the example is the only device in the Xenta
group called 2nd_Floor you could remove the complete Xenta
group.
Udating the Network Information
The LonWorks network was changed when you deleted the Xenta group
and the Xenta 401 device. TAC Vista alerts the user of this by showing
the LonWorks network object with an asterix. To update the network
information you have to make a new commission and download of the
network.
For more information on how to commission and download the LonWorks network, see the TAC Xenta Server – TAC Networks, Technical
Manual.
Once you have deleted the appropriate object and updated the network
information you will complete any additional work in XBuilder.

Using TAC Xenta I/O Modules in the
Project
The Xenta Server object and the XBuilder project have already been
created in Vista and stored in the Vista database. For more information,
see the TAC Xenta Server – TAC Networks, Technical Manual.
The LonWorks Network object that is connected to the Xenta Server is
imported by XBuilder; it can be viewed in the network pane in
XBuilder. The Xenta 401 device and the original I/O modules are no
longer part of the LON network.
The Xenta 700 devices have no onboard I/O. Xenta I/O modules are
used when physical I/O points are needed in the control application.
If you require I/O points you, you can add the required types and number of Xenta I/O modules and configure them.
The workflow in XBuilder for adding Xenta I/O modules to the Xenta
Server is as follows:
•
Adding Xenta I/O modules for physical in- and outputs.
•
Defining the network address for the I/O modules (Neuron ID).
This work is performed by editing the Xenta Server project in XBuilder.

4 Using TAC Xenta I/O Modules in the Project
Assigning a Neuron ID for a TAC Xenta I/O
Module in TAC XBuilder
There are a number of different ways to configure the address for Xenta
I/O modules used with the Xenta Server. The method depends on the
availability of the network and also whether a Vista system is available.
•
Using XBuilder.
•
Using Vista Workstation, where you can,
•
•
use the Service Pin switch or
•
enter the Neuron ID manually.
Via the Xenta Server Service web pages.
The method you choose depends on the situation, whether a Vista system is available and the availability of an operating network.
For more information on other ways to configure the address for Xenta
I/O modules see Section 17, “Configuring the Device Address for a
TAC Xenta I/O Module”, on page 129.
When working with XBuilder, the Xenta I/O modules are not online and
the address is defined by entering it manually.
In our example, you will use XBuilder to enter the Neuron ID to address
the Xenta I/O module.

Verifying the TAC Xenta I/O Modules
in the Project
To verify the functionality of the I/O modules and view connected signals in the Xenta device, you can generate and send the additions you
made to the Xenta Server project and view the result on the Xenta
Server web site.
The procedure for doing this is:
6.1
•
Save the project in the Vista database.
•
Send the project to the Xenta Server.
•
View the Xenta I/O modules using a web browser.
•
View signals in the Xenta I/O modules.
Saving a TAC Xenta Server Project in a TAC Vista
Database
When you save the Xenta Server project in the Vista database, the
project is automatically generated and can be sent to the device when
the save is finished. You can do this at any stage of the project, to
inspect the results.
XBuilder automatically builds a web site for the Xenta Server when the
project is generated. The pages in the web site we are currently interested in are Configuration and Utilities.
Tips
•
When the Xenta Server project is generated, XBuilder verifies
that the project does not contain errors that can cause the transfer
to fail. If you generate the project regularly, it is easier for you to
establish the causes of the errors.
•
If you want to generate the Xenta Server project without saving
it, click Generate on the Project menu.

7 Adding TAC Menta Objects to the Control Application
Adding TAC Menta Objects to the
Control Application
The control algorithms and logical designs of the control application are
created from Menta objects in the Xenta Server.
The workflow in our example in XBuilder for creating the control application in the Xenta Server is as follows:
•
Create Menta objects.
•
Define the Menta objects.
•
Add applications to the Menta objects.
This work is performed by editing the Xenta Server project in XBuilder.
7.1
Adding an Applications Folder
You can maintain a good structure in the XBuilder project by putting all
the control applications in a separate folder.
In our example you use an XBuilder folder for the Menta objects.
To add an applications folder
1
In XBuilder, in the system pane, right-click the root folder. In our
example, ACME_Building_A.
2
Point to New, and then click Folder.
3
Type the name. In our example, “Control_Applications”.

7 Adding TAC Menta Objects to the Control Application
7.2
TAC Xenta Server – Controller, Technical Manual
Adding a TAC Menta Object
The major part of the control application in the Xenta Server comprises
one or more Menta objects. Each Menta object contains a Menta application. Menta objects are added using the system pane in XBuilder.
For more information on how to create new Menta applications, see
TAC Menta, Technical Manual.
In our example, existing Menta application files are used for the control
application.
To add a TAC Menta object
1
In XBuilder, in the system pane, right-click the application folder
where you want the control application to be located. In our example, the Control_Application folder.
2
Point to New, point to Object and then click Menta Object.
3
Type the name. In our example, “RTU4_Zones”.
Adding Menta objects one at a time
In order to take full advantage of the characteristic that allows the Xenta
Server to use an application comprising a number of smaller parts, the
control application should be constructed using several Menta objects.
Repeat the procedure above to create all required number of Menta
objects.
In our example, the remaining parts of the control application is divided
in two Menta objects. One Menta object for air handling parts and one
for executing the logic for the chillers.
•
RTU4_AHU
•
RTU4_CoolingLogic
Repeat the procedure above to add these to the Control_Applications
folder.
Note
•
52 (240)
The order of Menta object creation in the system pane is not
important. However, when making connections, it can be useful
to have the Menta objects in a given order as this facilitates an
overview. To achieve the desired order, you can use the Move up
and Move down buttons in the toolbar.

7 Adding TAC Menta Objects to the Control Application
Adding a TAC Menta Application File
The Menta objects can acquire an application code by using an existing
Menta application file or by creating a new one.
There are two methods of locating an existing Menta application. It can
be imported directly to XBuilder or via an opened Menta programming
tool.
For more information on other ways to add the Menta applications, see
Section 21, “Using TAC Menta Application Files in TAC XBuilder”,
on page 169.
In our example, existing Menta applications are imported to the Menta
objects using XBuilder.
7.3.1
Importing a TAC Menta Application File to a TAC Menta Object
One of the ways to import a Menta application file is to browse and
import the application file directly to XBuilder.
In our example, you will use existing Menta applications for the air handling unit RTU4. The applications are located in the folder
ProjectACME\DeviceDescr\Menta_Files_to_X700.
To import a TAC Menta application file to a TAC Menta
object
1
In XBuilder, in the system pane, right-click the required Menta
object. In our example, the RTU4_Zones.
2
Click Import.
Important
•
When you import a Menta application file and view errors and
messages, make sure the output pane in XBuilder is visible and
that filtering is switched off.
•
Unallowed characters in block names, inputs, outputs, alarms,
time schedules, public signals and public constants used in the
existing .mta file are converted to underscore characters.
3
In the Open dialog box, browse to the required Menta application
file. In our example, the RTU4_Zones.mta.
Notes
•
Browsing a Menta application from XBuilder will only show
Menta project files (files with the extension .mta).
•
To use a Menta function block diagram with the extension .aut
you must open Menta from within XBuilder and then import the
file.

Click Open.
Important
•
Unallowed characters in block names, inputs, outputs, alarms,
time schedules, public signals and public constants used in the
existing .mta file are converted to underscore characters.
When the import is finished, the Menta object is expanded to show the
first sub-level of the pre-defined substructure of the object.
A signal is located in an additional subfolder if the signal is a part of a
Menta module.
Physical I/Os in the imported Menta application are automatically
replaced with new blocks, connection blocks, when a Menta application
file is imported.
Important
54 (240)
•
If the imported Menta application contains physical I/Os defined
as SNVTs, a connection block of a type corresponding to the
SNVT is created. The SNVT definition is thereby discarded and
a text file for each Menta object listing all the definitions is created automatically.
•
The definition as SNVT is discarded, but an automatically created text file for each Menta object, listing all the definitions is
created.
•
The event and location of the text file is listed in the output window, under the Generate tab. If you double-click the line in the
list, the text file is opened in a text editor and you can save the
file in a suitable location.

TAC Xenta Server – Controller, Technical Manual
7 Adding TAC Menta Objects to the Control Application
A Xenta Server alarm object is automatically created in the Alarms
folder for each ALARM block in the imported .mta application file.
When you import a Menta application file containing a trend log, the
defined trend log in the .mta (source) file is automatically converted to
a corresponding Xenta Server trend log.
After the import to the Menta object, the trend log objects are collected
on the same level in the system pane hierarcy as the Menta object it was
imported to.
You can move a Trend Log object to another suitable location by selecting the object and click Move up or Move down.
The trend log object retains the signal to log and the other log settings
when it is imported by XBuilder.
Trend logs are numbered when they are imported. The numbering is visible as the last numeral in the trend log object name. If you reimport a
trend log it will be given a new and higher trend log number.
Important
•
Deleting a Menta object that has contained trend log objects, will
not remove the trend log objects created by XBuilder.
•
If you import the same application or another Menta application
a new set of Trend log objects will be added XBuilder.
When you import a Menta application file, any existing ERR function
block in the .mta source file will be replaced with a ERROR function
block.
Important
•
The ERROR function block detects fewer system errors than the
ERR function block.
If the original ERR block uses bits, not adjusted by the replacement
ERROR block, some changes of the Menta application might be
needed.
For more information on the ERROR function block functionality, see
the TAC Menta, Technical Manual.

as the exercise proceeds.
Tip
•
If an import that fails, you can edit the Menta object, and troubleshoot the application in the Menta programming tool.
Adding Applications One at a Time
When the control application uses several Menta objects, each Menta
object contains a Menta application.
Repeat the procedure above to import all required Menta application
files.
In our example, import the following Menta applications to each Menta
object:
•
Import the RTU4_AHU.mta application to the RTU4_AHU Menta

8 Assigning a Control Task to TAC Menta Objects in The Control
Assigning a Control Task to TAC
Menta Objects in The Control
Application
The control application in each Menta object is executed in a control
task. Xenta Servers have a set of control tasks, each with a preset cycle
time. You must assign a control task to each Menta object application
you want to be run.
If neccesary, you can control the order of execution of the Menta object
codes.
To complete this work you must edit the Xenta Server project in
XBuilder.
For more information about control tasks in a Xenta Server 700, see
Section 23, “Control Tasks in TAC XBuilder”, on page 189.
8.1
Assigning a Control Task for a TAC Menta Object
When you assign a control task to the Menta object the application in
the Menta object will be executed within the assigned control task cycle
time.
In our example you assign the application code to be executed in the
medium fast control task.
To assign a control task to a TAC Menta object

9 Modifying and Refining Objects in the Project
Modifying and Refining Objects in
the Project
When you imported the Menta applications, some objects were automatically created by XBuilder and you may find it necessary to modify
them.
A recommended workflow in XBuilder when creating the control application in the Xenta Server is as follows:
9.1
•
When necessary, create and connect Time objects.
•
When necessary, create, modify and connect Alarm objects.
•
When necessary, create, modify and connect Trend Log objects.
•
When necessary, modify the Menta application when using the
ERR function block.
Time Objects in the Control Application
The control application in the Xenta Server uses Xenta Server Time
objects. Time objects are automatically created by XBuilder when a
Menta application containing time schedule blocks is imported to the
Menta object. The original TSCH function block in the Menta application is replaced with a TSCHI function block.
For more information on Xenta Server time objects, see the TAC Xenta
Server – Web Server, Technical Manual.
In our example, the application contains an automatically created time
object in one of the Menta objects. The scheduling is used within the
Menta object and you do not need to make any changes.
Note
•
Schneider Electric Buildings AB, Feb 2011

9.2
TAC Xenta Server – Controller, Technical Manual
Alarm Objects in the Control Application
The control application in the Xenta Server uses Xenta Server alarm
objects. Alarm objects are automatically created by XBuilder when a
Menta application containing an alarm is imported to the Menta object.
Alarm objects can also be manually created.
For more information on Xenta Server alarm objects, see the TAC Xenta
Server – Web Server, Technical Manual.
In our example, the application contains several automatically created
alarm objects in the Menta objects. The logical state of each alarm are
used within each Menta object and you do not need to make any
changes.
9.3
Trend Log Objects in the Control Application
To log signals in the Xenta Server, you use Xenta Server trend log
objects in XBuilder. Trend logs are automatically created by XBuilder
when a Menta application containing trend logs is imported to the
Menta object.
Trend Log can also be manually created.
For more information on how to create a trend log in XBuilder, see the
TAC Xenta Server – Web Server, Technical Manual.
In our example, the imported Menta applications contain several automatically created trend logs and you do not need to make any changes
to them.
9.4
I/O Signals as SNVTs in the Control Application
The control application in XBuilder can use SNVTs. The Menta object
uses the required type of connection block and separately created and
defined SNVTs are connected.
9.4.1
I/O Signals as SNVTs from an Imported TAC Menta Application
Physical I/Os, defined as SNVTs, in a Menta application you import can
be either digital (DI/DO) or analog (AI/AO) type. The I/Os are automatically replaced with connection blocks, when the Menta application file
is imported. In the ordinary version of Menta the AI and AO function
blocks are used for SNVTs of both real and integer type. In the XBuilder
version of Menta, different connection blocks must be used.

9 Modifying and Refining Objects in the Project
Changing Connection Block Type
A typical way to adapt the result of an imported Menta application using
SNVTs, is to make sure that the automatically created connection
blocks are the required type and if necessary replace them.
In existing Menta applications, inputs and outputs defined as SNVTs
are often integers. In the XBuilder version of Menta the connection
blocks II or IO must be used.
In our example, XBuilder automatically replaced a few AI function
blocks with RI connection blocks when the RTU4_Zones.mta application file was imported.
As these SNVTs are integers, the “crystal ball” will tell you that this will
cause problems when connecting to the appropriate SNVTs later in the
project.To avoid these problems, you will need to edit the imported
Menta application and replace the RI function blocks with II function
blocks. To make the changed II connection blocks to function properly
in the application you will also add conversion operators.
A suggested working method is:
•
Create one new II function block.
•
Add a Conversion operator.
•
Connect the two new elements.
•
Make a copy of the two elements.
•
Copy the Names and Descriptions from the existing (RI) function
blocks to the new function block.
•
Disconnect and delete the existing (RI) function block.
•
Move the new two elements in position.
•
Connect the two elements.
•
Repeat the procedure for all required function blocks.

ERR Blocks in the Control Application
In the control application for the Xenta Server you cannot use the Menta
ERR system block. The control application in a Xenta Server can use
the Menta ERROR function block and also many system variables and
signals in XBuilder.
9.5.1
ERROR Blocks in an Imported TAC Menta application
When you import a Menta application file, any existing ERR function
locks in the .mta source file will be replaced with a ERROR function
block.
In our example, XBuilder automatically replaced a some existing ERR
function blocks with ERROR function blocks when the
RTU4_AHU.mta application file was imported..
Important
•
9.5.2
The Menta function blocks ERR and ERROR differ in functionality. For more information on these function blocks, see the TAC
Menta, Technical Manual.
Adapting a TAC Menta Application for the ERROR Block Design
Existing Menta application sometimes need to be modified when used
in a Xenta Server.
A typical example is when a Menta application uses any bit value which
the ERROR function block does not adjust. Changing the Menta function block diagram to use a system variable in XBuilder can often solve
the problem.
In our example the ERR block is used for detecting when an I/O module
is oflline and also if any I/O point is in a forced state. An I/O module
offline is detected by the state of bit 11 (value of the block 2048).
Adjusting the bit 11 is handled by the new ERROR block. If an I/O point

is in a forced state is detected by bit 12 (value of the block 4096).
Adjusting the bit 12 is not handled by the new ERROR block.
To Adapt a TAC Menta Application for the ERROR Block
Design
1
In XBuilder, in the system pane, right-click the required Menta
object. In our example, the Control_Applications-RTU4_AHU.
2
Click Edit to open the application in Menta.
3
In the Menta editor window, find the I/O Alarm part of the design.
4
Right-click the connection line to the function block to disconnect.
In our example, the input to the lower XPB function block.
5
Click Detach to break the connection.
The system variable you will use is a boolean signal, ready to connect
to an ALARM block, so you do not need to decode the value of an
ERROR block. You can delete the XPB block.

Select the lower expression block and then click Delete to remove
the block.

Notes
•
The above described modification is not the same as detecting
the state of bit 12 in the original ERR function block. The modified design detects only I/O that are overridden by switches in
the I/O modules.
•
Detecting this override state can also be done by changing the
expression block to detect the value 32.

10 Adding SNVT Objects to the Project
Adding SNVT Objects to the Project
When you imported the Menta applications, signals that included
SNVTs were not complete. SNVTs must be created and defined manually.
The workflow for creating the control application in the Xenta Server is
as follows in XBuilder:
•
Add controller objects for the SNVTs.
•
Create the required SNVTs.
This work is carried out in XBuilder.
Tip
•
10.1
Use the list containing the definitions of the omitted SNVT definitions generated when the Menta application was imported to
help you.
SNVT Objects in the Control Application
The control application in Xenta Server can use SNVTs and make them
available on the LonWorks network. The SNVTs can also be made
available in Vista, for example, when the Xenta Server is installed as a
LonWorks device in a classic network.
For more information about SNVTs, see the TAC Xenta Server – Gateway, Technical Manual.
Important
•
Many SNVTs are 32 bit integer variables. Depending how you
use these SNVTs in a Menta object, the Menta application will
have to be designed to handle the variable values. For more
information on this, see the TAC Menta, Technical Manual.
In our example the control application uses a number of signals defined
as SNVTs.

TAC Xenta Server – Controller, Technical Manual
SNVTs from an Imported TAC Menta application
A connection block of the corresponding type will be created for any
existing I/O block in the .mta source file when you import a Menta
application file. The signal object is located within the structure of the
Menta object.
Important
•
If the imported Menta application contains physical I/Os defined
as SNVTs, a connection block of a type corresponding to each
SNVT is created. The definition as SNVT is discarded, but an
automatically created text file for each Menta object, listing all
the definitions is created.
•
The event and location of the text file is listed in the output window, under the Generate tab.
•
If you double-click the line in the list, the text file is opened in a
text editor and you can save the file in a suitable location.
In our example, the control application uses a number of signals defined
as SNVTs. You will have to create the SNVTs manually and also make
the connection to the signal object.

10 Adding SNVT Objects to the Project
Adding a Controller Object
Controller objects are used in the Xenta Server to collect SNVTs.
One controller object, the Node object 0, is pre-configured and cannot
be changed. It contains the SNVTs for the Xenta Server as a device.
If other SNVTs are used, they must be created in a controller object.
You can create several SNVTs in one controller object. You can use
several controller objects to structure the SNVTs to meet your requirements.
In our example, you add four controller objects to structure the SNVTs
to be used in the application.
To add a controller object
1
In the network pane, right-click IP Backbone-TAC_Xenta_731-SNVTs-LonMarkObjects and then click
New Controller Object.
2
Name the new controller object. In our example, enter
“TERM_UNITS”.
Adding Controller Objects One at a Time
It is often convenient to use several control objects in order to improve
the overview of the SNVTs. Repeat the procedure described above and

11 Connecting Signals in the Project
Connecting Signals in the Project
The Menta objects are now created and they have been allocated a
Menta application code. Each Menta object is associated to a control
task with a suitable cycle time, and the execution order for the parts of
the application is determined.
Signals in the application are created automatically by XBuilder or
manually, however they are not connected.
The continued workflow in XBuilder for creating the control application in our example is the following:
•
Connect signals between Menta objects.
•
Connect signals between Menta objects and SNVTs.
•
Connect signals between Menta objects and physical in- and outputs in the I/O modules.
•
Connect system signals to Menta objects.
In XBuilder you can connect signals using different methods. You can
drag and drop signals within the system pane or between the network
pane and the system pane. You can also connect signals using the very
useful filter view in XBuilder.
The Filter view is normally synchronized to show all signals that can be
connected to the selected signal in the system pane.
The Filter view shows the combination of items from both the system
pane and the network pane. The filter view is a tabbed version of the network pane.
Using the filter view is particularly useful when you want to connect
signals in XBuilder projects with an extensive structure. Finding an
already connected signal is also very easy using the filter view.
Fore more information on allowed connections of signals, see
Chapter 33, “Connecting Rules in TAC XBuilder”, on page 231.

Tips
•
You can see whether an input signal is connected or not by looking at the signal icon in the system pane tree structure.
•
If the signal is not connected you will see a red cross at the
bottom right part of the icon.
•
The red cross disappears when the signal is connected.
•
You can find all the objects a signal is connected to by
right-clicking the required signal, clicking Show Connections
and then viewing the result in the output pane.
•
You can verify the signal and path for a connection by clicking
the required signal and then view the path in the Connection-Reference box in the properties pane.
Connecting Signals One at a Time
In a control application there are several signals that generally need to
be connected between various Menta objects. Repeat the procedure
above to connect all required signals.

Connecting a Signal to a SNVT
Sometimes in a control application, signals communicate with such
devices as SNVTs. The SNVTs, located in the network pane, are connected to signals in Menta objects, located in the system pane
Important
•
Many SNVTs are 32 bit integer variables. Depending how you
use these SNVTs in a Menta object, you might need to connect
the SNVT to two signals in the Menta object. For more information on this, see the TAC Menta, Technical Manual.
Sometimes in your control application, SNVTs communicate with
devices outside the XBuilder project. To achieve this communication,

Connecting a Signal to a TAC Xenta I/O Point
You connect signals in the Menta objects to the required physical I/O
points located in the network pane in XBuilder. The signals in Menta
objects are located in the system pane and you use the filter view pane
to find the required signals. The signal that is normally used in an I/O
point is the Value signal. Other signals can be used for special purposes.
For more information on I/O points in XBuilder, see the Chapter 18,
“Using I/O Points in TAC XBuilder”, on page 137.
In our example, you connect the status indication for the supply fan to
the I/O point for the indicating signal.

11 Connecting Signals in the Project
Connecting a Pulse Output Signal to a TAC Xenta
I/O Point
In the control application you sometimes use control algorithms where
the output signal is a pulse with varying duration. The Menta function
block PIDI is a typical example.
The output from the controller PIDI is a floating point value, defining
the duration of the requested pulse. The digital output in the I/O module is normally a Boolean value and the connection would not be possible if the two signals had be the same type. This problem is overcome
by XBuilder automatically adapting the type of the I/O point signal to
be a floating point (REAL) type when the digital output I/O point is
configured as pulse.
Important
•
The data type for the Value signal in a digital physical output, is
normally declared as BOOL.
•
When the physical output is configured as pulse output, the data
type for the Value signal is automatically declared as REAL, and
allows you to connect the output signal of the PO block to the
physical output in XBuilder.
When you need to define a minimum duration of the output pulse, you
assign a value in the MinPulse parameter of the Menta PO connection
block
In our example you connect the pulse output signal from the Menta
block to a digital I/O point where the output type gives a pulsed output.
To connect a pulse output signal to a Xenta I/O point
1
In the system pane, expand the required Menta object to view the
signals. In our example, click
Xenta_Server_A-Control_Applications-RTU4-AHU-Relief-Outputs.

Preparing Logical Signals for the Web
This chapter describes a way to arrange signals so they are identical to
the collection prepared in the TAC Xenta Server – TAC Networks, Technical Manual.
15.1
Arranging Signals to be used in the Project
Physical signals in the network connected to the Xenta Server are used
in the graphic presentation, for alarms, trend logging and other usage.
To simplify the engineering, the signals are connected to signal objects
in XBuilder.
In the following example, signals from the control application for
RTU4, required by an example graphic in the TAC Xenta Server – Web
Server, Technical Manual.
15.1.1
Adding Signals
In order for a graphic to display values from a signal or for a trend log
to log a value you will reference the signal from the graphic or the trend
log. These signals need to be added in XBuilder before they can be referenced.
To simplify the engineering the signals are best placed in a separate
folder for each device. For large applications it may be useful also to
imitate the Menta module structure in the folder.
To add signals
1
In the system pane, right-click the folder where you want to add a
folder for your signals. In our example, ACME_Building_A-Control Applications.
2
Point to New and click Folder.

•
When a LonWorks Network device is added in Vista Workstation, TAC Vista changes the value for the receive timer in the
XBuilder project. The changed value (24576 ms) is often too
long for maintaining good communication when many Xenta I/O
modules are connected to the Xenta Server. In such cases the
value must be decreased until the required communication is
achieved.
•
You decrease the value for the receive timer in XBuilder, by
clicking LON in the Network pane and selecting an appropriate
value in the properties pane, under File Transfer Timers, in the
Receive Timer property list.
When the Xenta Server is a subsystem to TAC Vista Workstation,
the value for the timer shall be changed in TAC Vista Workstation. For more information about changing the value, see
Chapter 32.1, “Changing the Receive Timer Value in TAC Vista

Table 18.3:
Property
Unit Prefix
Optionally selected by the user from the Unit
Prefix list.
When you configure a universal input for a user defined input current
range you change the input range by using the Multiplier and Offset
properties.
The Multiplier property is a value for the ratio of maximum input range
and actual input range.
The Offset property is a value added to the lowest actual input signal
level to result in 0 (zero).
Example
Assume an application where a signal input level of 4 mA is the lowest
level and 20 mA is the highest input level. 4 mA shall result in 0 percent,
20 mA shall result in 100 percent.
Multiplier = Maximum input range / (Highest actual input signal
level – Lowest actual input signal level).
The maximum input range for the current input is 0 mA – 20 mA = –20
mA.
The required input span is 20 mA – 4 mA = 16 mA.
The ratio between maximum and actual range is 20/16 = 1.25.
The above calculations gives us a Multiplier = 1.25.
The Offset value is always calculated for a signal value converted to a
range from 0 to 100.
The actual input level that shall give 0 (zero) is 4 mA.
Offset = Input level for zero * Multiplier * (Signal value range/Maximum input range) *(-1)
Offset = 4 * 1.25 * (100/20) * (-1)
The above calculations gives us an Offset = –25.

Unit Prefix
Optionally selected by the user from the Unit
Prefix list.
When you configure a universal input for a user defined input voltage
range you change the input range by using the Multiplier and Offset
properties.
The Multiplier property is a value for the ratio of maximum input range
and actual input range.
The Offset property is a value added to the lowest actual input signal
level to result in 0 (zero).
Example
Assume an application where a signal input level of 2 volts is the lowest
level and 8 volts is the highest input level. 2 Volts shall result in 0 percent, 10 volts shall result in 100 percent.
Multiplier = Maximum input range / (Highest actual input signal
level – Lowest actual input signal level).
The maximum input range for the voltage input is 10 volts – 0 Volts =
10 Volts.
The required input span is 10 volt – 2 Volt = 8 volts.
The ratio between maximum and actual span is 10/8 = 1.25.
The above calculations gives us a Multiplier = 1.25.
The Offset value is always calculated for a signal value converted to a
range from 0 to 100.
The actual input level that shall giving 0 (zero) is 2 Volts.

Offset = Input level for zero * Multiplier * (Signal value range/Maximum input range) *(–1)
Offset = 2 * 1.25 * (100/10) * (–1)
The above calculations gives us an Offset = –25.
Adapting the converted values to other ranges can be done, using the
Minimum Value and Maximum value properties.

The Analog Output Y
The analog output Y in a Xenta I/O module is used for a voltage signal
output. The IO Point Type property cannot be changed.
The analog output Y can be configured to limit either the physical output signal range within 0–10 volts or the input signal span to give the
fixed output signal range 0 to 10 volts.
Normally the analog output Y is used for giving a physical output voltage signal from connected signal values ranging from 0 (zero) to 100.
When the default category for the analog output Y percentage is used,
the utilization of the physical output voltage range is defined by the two
properties Voltage at 0% and the Voltage at 100%.
When other categories are defined, the fixed output signal range 0 to 10
volts is calculated from the connected signal value where the value of
the Minimum Value property results in 0 (zero) volts output level and
the value of Maximum Value property results in the output level of 10
volts.

20 TAC Menta Objects in TAC XBuilder
TAC Menta Objects in TAC XBuilder
Menta objects in XBuilder contain the application code, which is
designed and programmed in the Menta programming tool. A complete
application in the Xenta 700 controller can consist of several Menta
objects.
A Menta application created in the XBuilders version of Menta cannot
be used in the generic version of Menta.
Menta applications created for Xenta 200/300/400 can be re-used by
importing them to the Menta objects in XBuilder.
When the Menta programming tool is started from XBuilder it always
saves the Menta application as an Menta application file (.mta) file.
Browsing Menta application files from XBuilder will only find .mta
files.
It is possible to re-use an application file of .aut type, however, these
files must be imported to Menta, when Menta is opened from XBuilder.
Copy and pasting a design between two instances of Menta will only
work between diagrams for Xenta 700 devices. Reusing designs from
other type of device should be done using the import function.

TAC XBuilder
Control algorithms and logical design in the control application is made
up of one or more Menta objects in the Xenta Server. The Menta objects
contain the application code and are added in the System pane in
XBuilder.
The Menta objects can obtain the application code either by using an
existing Menta application file or by creating a completely new one.
There are different ways to re-use an existing Menta application. You
can import it either directly to XBuilder or via the opened Menta programming tool.

The Specialized TAC Menta Programming Tool
When Menta is opened from XBuilder, the functionality of the programming tool is specialized for creating applications to run in the
Xenta 700 device. A major difference from the original Menta programming tool is that the use of some function blocks differs. These are:
•
Function blocks for physical I/O points.
There are no physical I/O blocks in the Menta application for the
Xenta Server. Function blocks representing physical I/Os are
replaced with connection blocks. These connection blocks are connected to signals in physical I/Os in XBuilder.
However, if the I/O point is defined as a SNVT, no SNVT is created, but a LIST specifying the SNVT for each point is generated.
You must create the SNVTs manually and make the connection to
the signal object.

DOPU function blocks.
The special pulse output block DOPU in a Menta application
is replaced with a PO block. This blocks is later connected to
a signal in a physical I/Os in XBuilder.
•
ALARM function block.
An Xenta Server Alarm object is automatically created by
XBuilder for each ALARM block in a Menta diagram which is
introduced to a Menta object in a XBuilder project.
The Xenta Server Alarm object is created in a sub-folder to the
Menta object and named Alarms. The Xenta Server Alarm
object is also located in an additional folder if the ALARM
block is a part of a Menta module.
•
TSCH function block.
A Time Schedule Reference object is automatically created by
XBuilder for each TSCH block in a Menta diagram which is
introduced to a Menta object in a XBuilder project. XBuilder
creates the Time Schedule Reference object in a sub-folder to
the Menta object and names the folder Time objects. The Time
Schedule Reference object is also located in an additional
folder if the TSCH block is a part of a Menta module.
The original TSCH function block is replaced with a TSCHI
function block in the application code for the Menta object in
XBuilder.
•
ERR function block.
The functionality of the ERR function block, available in
XBuilder, is modified for the Xenta 700 device. The original
ERR function block is replaced with a ERROR function block
in the application code for the Menta object in XBuilder.

Creating a New TAC Menta Application File
When you make control designs you often can re-use existing designs,
although you might need to modify them. Sometimes you must create
completely new control functions in Menta; this can be achieved by
using connection blocks in the Menta application and XBuilder objects
for Time objects, Alarm objects and Trend logs.
The following is an example of how to create a new Menta function
block diagram. The example is a much simplified Menta solution to
obtain an alarm in the system and generate a response on a physical
device when a button is pressed.
For more information on how to create a Menta application, see the TAC
Menta, Technical Manual.

22 Using the TAC Menta Library in TAC XBuilder
Using the TAC Menta Library in TAC
XBuilder
Sometimes the control application can be designed so that the code in a
Menta object can be used several times. A solution for this is to work
with Menta objects in the XBuilder Menta Library. A Menta object
located in the library is used as a source object and references to the
library object are used in the control application.
Parameters and settings in the referenced Menta objects can be customized.
One of the advantages of working with the Menta Library is that you can
change the Menta code in the library object and the change will be effective in all referenced objects.
Another advantage is that the Menta objects in a Menta Library can be
exported for use in other XBuilder projects.
A Menta object can be created in the XBuilder Menta Library in two
ways:
•
Create a new Menta object in the library.
•
Promote an existing Menta object to the library

objects.
22.9
Deleting a TAC Menta Library Object
Deleting a Menta Library object will result in changes if a Menta object
is referencing the library object. If no Menta object is referencing the
library object there are no consequences. If there are Menta objects referencing the library object you delete, the referenced objects are
changed to local Menta objects.
Important
•
When you delete a Menta Library object all Menta objects referencing the library object are changed to local Menta objects.
To delete a TAC Menta library object
1
In the Network/Menta library pane, click the Menta Library tab.
2
Right-click the Menta library object you want to delete and then
click Delete.
3
In the TAC XBuilder confirmation dialog, click Yes.
The library object is deleted from library.

23 Control Tasks in TAC XBuilder
Control Tasks in TAC XBuilder
The entire control application in the Xenta Server is executed in one or
more control tasks. There are five control tasks with different cycle
times. Which task to use for the application, or parts of it, depends on
how quick a response is required.
The code for several Menta objects can be run in the same control task.
The execution of each control task is supervised by the system and
important information is available as system variables in XBuilder.
23.1
Control Task Properties
There are five control tasks in a Xenta Server 700.
•
Fast
•
Medium Fast
•

The Control Task Cycle Time
Each control task in the Xenta Server 700 has a predefined cycle time.
The cycle times cannot be changed.

23 Control Tasks in TAC XBuilder
TAC Xenta Server – Controller, Technical Manual
The execution of a control task is restarted with the periodicity approximately equal to the cycle time.
Table 23.2:
Task
Cycle Time
Fast
100 ms
Medium Fast
500 ms
Medium
1000 ms (1s)
Medium Slow
5000 ms (5s)
Slow
10000 ms (10s)
You select to run your Menta object application code in a control task
with the cycle time required for the application.
Control tasks with shorter cycle times are normally used when fast
response is required. An example of such applications is light control.
The code in a Menta object that requires an execution time of 600 ms is
not suitable to be executed in a Fast or Medium Fast task. The application will generate overruns. Such an application can be executed in
either the Medium, Medium Slow or Slow task.
Which of the slower tasks to use depends on the allowed length of the
cycle time. If, for example, a cycle time of 5000 ms is accepted, the
Medium Slow control task can be used; otherwise the Medium control
task is suitable.
The total execution time for the code in all Menta objects in the same
control task should not exceed the cycle time of the task. If the cycle
time is exceeded, a control task with a longer cycle time should be used.
Alternatively the total application might be revised by executing the
some of the Menta objects in a control task with a longer cycle time.
If the execution time is longer than the cycle time for the task it will
mean that the application will never be executed with the designed cycle
time. All application code in the task will be executed with the necessary execution time, but the next execution of the task will start when
the task is scheduled to start. The resulting cycle time will then be as
much as twice than intended.

23 Control Tasks in TAC XBuilder
Accessing Execution Time Values for the Control
Tasks
The execution of each control task is supervised by the system in the
Xenta 731 and important values are available in two ways:
23.4.1
•
As system variables in XBuilder.
•
As values accessed via the service web.
Control Task System Variables
The control task system variables in the Xenta Server 700 can be made
visible in TAC Vista graphics or on web pages. You can also use them
in a design where an alarm is generated at a required level.
For more information on how to use Xenta Server signals in a TAC
graphic, see the TAC Xenta Server – Web Server, Technical Manual.
For more information on how to create an XBuilder alarm object, see
the TAC Xenta Server – Web Server, Technical Manual.
The available system variables for each control task are listed in the
table below:
Table 23.3:
Name
Description
Type
Cycle time
Cycle time for the task [ms]
Real
Latest exec time
Latest achieved execution time [ms]
Real
Max exec time
Maximum execution time [ms]
Real
Min exec time
Minimum execution time [ms]
Real
Overruns
Total number of overruns
Integer
Overruns quota
Percentage of overruns last hour
Real
Clear all
Clears all data for the task, if true
Boolean
The variables are located in the network pane, in the System Variables
folder.
The execution time of a control task is particularly interesting during the
design and commissioning phase.
If, for example, the Min execution time is longer than the cycle time for
the task it will mean that the application will never be executed with the
intended cycle time. All application code in the task will be executed
with the necessary execution time, but the next execution of the task
will start when the task is scheduled to start. The resulting cycle time
can in such case be almost twice the intended.

23 Control Tasks in TAC XBuilder
TAC Xenta Server – Controller, Technical Manual
Another variable of special interest is the value of Overruns in a task.
The value for Overruns shows how many times the task has not executed within the cycle time for the task.
If there are an increasing number of Overruns, it indicates the need to
use a control task with a longer cycle time, or that the control application should be re-designed.
The value for Overruns quota shows the percentage of overruns in the
last hour.
If the value for Overruns quota is low, it indicates a possibly temporary
overload on the task but the progress on overruns should be monitored.
Tip
•
23.4.2
One way to use the value of the Overruns quota is to connect it to
an XBuilder alarm object for generating an alarm.
Creating an Alarm for the Control Task Overruns System
Variable
One way to use the value of the Overruns quota is to connect it to an
XBuilder alarm object for generating an alarm. Choose a suitable alarm
level and delay for the application.
To create an alarm for the control task overrun signal
23.4.3
•
Create a new alarm object.
•
Configure the alarm object to take an analog value and that the
alarm shall be tripped if the value is greater than some decimal
value between 0 and 100 reflecting the percentage value of overruns desired.
•
Connect the overrun signal from a task to the alarm input.
Viewing the Control Task Execution Times Values Via the Service
Web
A page in the sevice web contains values for several of the system variables with information about the execution of the five control tasks and

Variables in a TAC Xenta Server 700
Variables in XBuilder are special signals and available only in Xenta
Server 700 devices. They are useful for sharing signal information
between parts in the network.
24.1
Automatically Added Variables
Three variables are automatically created by XBuilder, and are located
in a separate folder called Constants:
•
Binary Zero.
•
Integer Zero.
•
Real Zero.
You can rename or configure some of their properties like Data Type,
Initial Value. You can also choose to delete the variables.
A typical use of these three is to temporarily connect input signals in
Menta objects during the development of a project until the final connections are made.
Connecting input signals to these variables will satisfy XBuilders
demand that all inputs are connected and allow the project to be generated and saved to Vista database as well as downloaded to Xenta 700
devices.

25 Alarm Objects in the Control Application
Alarm Objects in the Control
Application
The control application in the Xenta Server uses Xenta Server alarm
objects.
Alarm objects are automatically created by XBuilder when a Menta
application containing an alarm is imported to the Menta object.
Alarm objects can also be created manually.
For more information about Xenta Server alarm object, see the TAC
Xenta Server – TAC Networks, Technical Manual.
25.1
The TAC Xenta Server Alarm Object in a TAC
Menta Object
The Xenta Server alarm object created from an ALARM function block
in a Menta object differs from the generic Xenta Server alarm object in
that there is no signal called “Input”. The input is defined in the Menta
application file (the Menta function block diagram). Otherwise, the
alarm objects in the Xenta Server are the same.
The scan time for an alarm is specified by the Scan time property for
the alarm object. The scan time is the interval to scan the input to determine the alarm condition.
The Menta application code, determining the condition for the alarm
(the input), is executed with the assigned control task cycle time.
The scan time is independent of the control task cycle time.

the alarm is acknowledged.
Output.
The alarm digital output.
The output is true as long as the
alarm condition is either:
•
ACTIVE or
•
PASSIVE and not
ACKNOWLEDGED.
If the alarm is blocked, the output is false.
State.
The alarm state output can be
used to describe the alarm status
in clear text, for example on values pages or in dialog boxes of a
dynamic object in graphics:
•
normal
•
active . unacked
•
active . acked
•
passive . unacked
•
blocked.
Values for the Delay On and Delay Off properties of the alarm, are
effective on the two signals Output and State.
25.2
Alarm Objects from an Imported TAC Menta
Application
A Xenta Server Alarm object is automatically created by XBuilder for
each ALARM block in a Menta diagram which is introduced to a Menta
object in an XBuilder project.

25 Alarm Objects in the Control Application
Adapting an Alarm Object
The functionality of the Alarm object created by XBuilder and the
Menta function block diagram is retained within the Menta object when
a Menta application file is imported.
If the state of the function block ALARM shall be used as input in other
Menta objects you need to make sure the application includes the necessary signal.
To provide for this there must be a public function block connected to
the output of the ALARM function block, to create the required signal
in the XBuilder Menta object. A BO connection block or a public XPB
function block are two alternatives.
!
Important
•
25.4
The state of the ALARM function block is not directly accessible
as a signal in the XBuilder Menta alarm object. There must be a
public function block, of boolean type, connected to the output of
the ALARM function block, to create the required signal.
Alarm Objects in a New TAC Menta Application
When you create a new Menta application you can use two types of
alarm. You can use the Menta ALARM block in the function block diagram or you can use XBuilder Alarm objects and connect them to an
input in the Menta object.
25.5
Creating an Alarm Page
To make alarms visible to the operator on a Xenta Server web site, a
alarm page is added to the XBuilder project.

TAC Xenta Server – Controller, Technical Manual
Connecting a Time Object to a TAC Menta Object
The functionality of the time object created by XBuilder and the Menta
function block diagram is retained within the Menta object when a
Menta application file is imported.
If you need to use the same time schedule in other Menta objects, the
appropriate output signal must be connected to all these Menta objects.
If you need to use the logical state of the time schedule in another Menta
object, you connect the signal called Output to an input in all these
Menta objects.
Note
•
The output signal in an XBuilder time object is, by default, of
real type.
If you need to use the value for time time before the time schedule is
active, you connect the signal called TimeLeft to an input in tall these
Menta objects.
In our example, the time object is used only internally in the Menta
object called AHU. There is no need to connect the signal to other
Menta objects.
To connect a time object to a TAC Menta object
26.3
1
In the system pane, expand the Menta object where you want to
use (connect) the time scheduling.

Time Objects in a New TAC Menta Application
When you create a new Menta application you can choose one of two
ways to organize time scheduling. You can use the Menta TSCHI block
in the function block diagram and let XBuilder automatically create the
time object or you can make a design where you use XBuilder time
objects, prepare inputs in the Menta application and connect them to the
XBuilder time objects.

I/O Signals as SNVTs in the Control
Application
The control application in XBuilder can use SNVTs. The Menta object
uses the required type of connection block and connected to separately
created and defined SNVTs.
The required SNVTs are additionally created in the network pane in
XBuilder.
For more information on how to create the SNVTs, see Section 10,
“Adding SNVT Objects to the Project”, on page 77.
28.1
I/O Signals as SNVTs from an Imported TAC
Menta application
Physical I/Os, defined as SNVTs, in a Menta application you import can
be either digital (DI/DO) or analog (AI/AO) type. The I/Os are automatically replaced with connection blocks, when the Menta application file
is imported. In the ordinary version of Menta the AI and AO function
blocks are used for SNVTs of both real and integer type. In the XBuilder
version of Menta, different connection blocks must be used.
28.2
Changing Connection Block Type
A typical need to adapt the result of an imported Menta application
using SNVTs, is to make sure that the automatically created connection
blocks are the required type and if necessary replace them.
For more information on how change the type of automatically created
connection blocks, see Section 9.4, “I/O Signals as SNVTs in the Control Application”, on page 64.

29 TAC OP7 Display Contents Considerations
TAC OP7 Display Contents
Considerations
TAC OP7 is a small but powerful operator panel designed to be used
with any TAC Xenta 700 series controller.
29.1
General
OP7 displays an adapted version of the web contents of Xenta 711/731
and the simulated web contents of Xenta 701/721. An end-user web display is not provided for these models.
When XBuilder generates the web pages for the Xenta Server, it also
generates the corresponding pages for the OP7 display. It should be
noted that although the OP7 does not have all the functionality of the
web pages, it does possess a few additional features.
The contents of the OP7 pages are configured in XBuilder and affect the
following:
•
The OP tree contents
•
The ‘root’ and other OP users
•
Hiding information from a user
•
Defining the ‘logged-out’ default page
•
The SC (shortcuts) tree
Each of these items is discussed in this chapter.
For more information about the operation of the OP7, please see the
TAC OP7 Operator Panel, Mini Manual.

29.2
TAC Xenta Server – Controller, Technical Manual
The OP Tree Contents
The OP Tree contains all possible pages (not Graphics) and values that
can be generated from the Xenta 700 web pages:
•
Values pages
•
Alarm pages
•
Time Object pages
•
Trend Log pages
•
Variables
•
System variables
•
I/O signals
In addition, the contents of a Default page (see Section 29.5, “Defining
the Default Page”, on page 216) will be defined.
29.3
The root and other OP Users
In XBuilder a ‘root’ user is created by default. The root user has full
access to all OP7 applications.
If additional users have to be defined, this is done in XBuilder. Additional users generally have limited access rights.
With one additional user defined, the default configuration for the OP7
will have the following structure.
Table 29.1: Access rights and contents of Shortcut and OP trees for different types of users
User
root
OP Access
Rights
Read/Write – all
SC Tree
Folder ‘System Variables’
Folder ‘Variables’
additional
Read – all
(none)
OP Tree
Folders
Values pages
Alarm pages
Trend log pages
Time schedule pages
Same as root
By default, both root and additional users have a complete OP Tree. The
root user has Read/Write access and the additional user has only Read
access. This can be modified, as described in the example below.
The example builds on the results obtained in the Getting Started part of
the TAC Xenta Server – Web Server, Technical Manual. We will
slightly modify the display structure for the ACME_Building_A.

29 TAC OP7 Display Contents Considerations
Hiding Information from a User
In order to hide or protect certain pages, folders, or information, visibility and access rights can be user defined for every user of the web and/
or the OP7 pages.
The Visible property for folders and pages in XBuilder applies to the
web pages and is ignored as the OP and SC trees are generated for OP7.
When users are defined for OP7, their access rights can be set for the
pages and folders displayed in the OP root user and additional user
trees.
With the exception of the root user, all defined users appear under OP
Access Rights.This is a property for a page/folder which can have one
of three values for each additional OP user (this does not include the
root user):
•
None – The object will not be visible to the OP7 user.
•
Read – The user can see the object/value, but cannot change it.
•
Read/Write – The user can see the object/value and has the right to
change it.
Notes
•
The Visible property for folders and pages in XBuilder is ignored
as the OP and SC trees are generated for OP7.
•
Other folders and pages can be created for OP7, and be hidden
for the web user by setting Visible to False.
•
The OP Access Rights property only affects the OP7 display.
•
The OP Access Rights property is not given as an option for the
root user, as the root user has Read/write access to everything.
To hide information from a user
1
In the system pane, click the System tab.
2
Click a folder or page that should be hidden from the user. In the
example, the Alarm page.

3
In the properties pane, under OP Access Rights for the specific
user, point to Read and click None. In the example, change
Frank’s Read to None.
4
Repeat steps 2-3 for the pages and folders you do not wish to be
displayed on the user’s OP7. In the example, click None for all
folders and pages, except for ‘Air_Handling’, that is:
Heating, Lighting, Security, Water, Energy, Time_Schedules,
Edit_Receiver_Groups, Graphic_Objects, and Receiver_Groups.
Note
•
29.5
Even if a folder only contains non-OP7 pages, the folder will still
be displayed in the OP unless you hide it by clicking ‘None’.
Defining the Default Page
The default page is a page that appears on the screen a certain time after
logging out. Any one of the pages in the OP tree can be assigned as
default page.
The default page is always present in XBuilder, but it will only be visible in OP7 if it has content. Contents must be defined with at least Read
access rights.
The default page is defined by selecting an existing page. The default
page will appear after a power-up, and, following a log out, after a specified time interval. The time interval is set in the General property
“Activate Default page in x min.”.
In the example, you will use a temperature chart.
To define the Default page
216 (240)
1
In the system pane, click the OP Users tab.
2
Click the Default Page.
3
In the filter view pane, expand the required folder. In the example,
expand the Air_Handling folder.

29 TAC OP7 Display Contents Considerations
Drag the required page to Default Page. In the example, drag
Temp_Chart to Default Page.
The SC (Shortcut) Tree
In OP7 an OP tree is always created for root and additional users. A
shortcut tree (‘SC Tree’) can also be designed for each user, including
the root user.
The shortcuts are references to pages that need to be displayed quickly
and easily.
SC Trees are defined in the System pane, under the OP Users tab.
29.6.1
Expanding the SC Tree for the Root User
As you saw in Section 13.1, “The OP7 Default Configuration”, on
page 117, the shortcut tree for the root user only contains two folders;
to make life easier you can add additional pages as required.
In the example, we will add the general Alarm page and the
Send_Trend_Logs page.
To expand the SC tree for root
1
In the system pane, click the OP Users tab.
2
In the filter view pane, drag the required page to Root in the OP
users pane. In the example, drag the page ‘Alarm’ to Root.
3
In the filter view pane, expand the required folder. In the example,
expand the Time_Schedules folder.
4
Drag the required page to Root. In the example, drag
‘Time_Schedules-Send_Trend_Logs’ to Root.

TAC Xenta Server – Controller, Technical Manual
Creating an SC Tree for an Additional User
As you saw in Section 13.1, “The OP7 Default Configuration”, on
page 117, there are no shortcut trees defined for additional users. An SC
tree has to be defined for each and every additional user.
In the example, we will add an Alarm page and some RTU4 data for
the user ‘Frank’.
To create an SC tree for an additional user
1
In the system pane, click the OP Users tab.
2
Right-click the additional user. In the example, Frank.
3
Point to New and click Folder.
4
Type the name of the folder. In the example, “RTU4”.
5
In the filter view pane, expand the relevant folder. In the example,
expand the RTU4 folder.
6
In the filter view pane, drag the required page to the user folder in
the OP users pane. In the example, drag the page
‘Alarms_in_RTU4’ to ‘Frank-RTU4’.
Repeat steps 5-6 as required.
In the example, drag the values page ‘C1_C4_Setpoints’ to ‘FrankRTU4’.
By default, all contents of the pages for additional users are ‘Read’.
If desired, change one or more of the pages to ‘Read/Write’.

30 ERR Function Blocks in the Control Application
ERR Function Blocks in the Control
Application
In the control application for Xenta Server controller you can not use the
Menta ERR system block. The control application in a Xenta 700 type
of device can use the Menta ERROR function block and also many system variables and signals in XBuilder.
30.1
ERROR Blocks in an imported TAC Menta
Application
When you import a Menta application file, any existant ERR function
block in the .mta source file will be replaced with a ERROR function.
Important
The Menta function blocks ERR and ERROR differ in functionality.
For more information on these function blocks, see the TAC Menta,
Technical Manual.
30.2
Adapting an ERR Block Design
Existing Menta applications sometimes needs to be changed when used
in a Xenta 700 controller.
A typical example is when a Menta application needs to be changed is
when the application uses a bit value which the ERROR function block
does not adjust. Changing the Menta function block diagram to use a
system variable in XBuilder can often solve the problem.
30.3
ERROR Blocks in a New TAC Menta Application
When you create a new Menta application, you have the option of using
the ERROR function block and suitable XBuilder signals and variables.

31 Parameters and Variables Management
Parameters and Variables
Management
This section describes how parameters and variables in TAC Xenta 700
are managed in certain situations.
The parameters/variables covered are:
•
Menta Function block values
•
Menta Constants values
•
Xenta 700 variables
•
Schedules
The situations described are:
•
Power failure
•
Download of an XBuilder project
•
Upload and download of parameters to/from TAC Vista
•
Value modifications
Terminology
Public Constant
A Menta Constant that has its Public checkbox set.
Public Block
A Menta Function Block with the Public checkbox
set.
Local modification
A modification that has been done to a value in
Xenta 700, using the Xenta 700 web or the
TAC OP7. Note that the Xenta 700 web can be
reached either using a web browser, or through
Vista Workstation, which is available in a folder
beneath the Xenta 700 object.
31.1
Power Failure
Menta Constants It is possible to do local modifications on Public
Constants. Public constants will keep their current
value after a power failure.
(In versions previous to 5.1.2 the value of the Public
Constant would always revert back to the value

entered in the Menta editor after a power failure, and
any local modifications be disregarded.)
Function Blocks
A function block with the Backup checkbox set will
keep its value over a power failure.
A function block with the Backup checkbox not set
reverts to its InitValue, if it has one; otherwise a new
value is calculated in the first cycle.
Xenta 700 variablesXenta 700 variables with the Backup set to “Yes”
will keep its value over a power failure.
Xenta 700 variables with the Backup set to “No”
will revert to its InitValue after a power failure.
Schedules
31.2
Xenta 700 schedules retain all events and their data
and time over a power failure.
Download of an XBuilder Project
When an XBuilder project is to be downloaded to a Xenta 700 the user
will be prompted for what to download:
Send all project and language files will download the complete
project including the language pack. Parameters that have been modified are overwritten with the values from the XBuilder or Menta project.
Xenta 700 will restart. This should basically only be used when you
change language pack or when you want to restart from scratch.
Send all project files and Send modified project files are basically the
same, except for the fact that the Send all project files will transfer the
whole project, while Send modified project files will only send the
changes. This means that the download time is shorter for the last alternative. In both cases, the execution is not interrupted.
When you download an XBuilder project to Xenta 700, using one of the
alternatives Send all project files or Send modified project files, the
parameters are handled in the following way:
Public Blocks
224 (240)
Blocks with the Backup checkbox set, will retain the
current value in the device. Blocks with the Backup
checkbox cleared, will be overwritten with the value
from the downloaded project, with one exception:
Schneider Electric Buildings AB, Feb 2011
04-00123-05-en
TAC Xenta Server – Controller, Technical Manual
31 Parameters and Variables Management
If there are no changes to the Menta program where
the block resides and Send modified project files is
used, the value from Menta will not be sent to the
device, and consequently the value will not be overwritten.
Xenta 700 variables
If Backup is set to “Yes” Xenta 700 variables will
retain their value. If the Backup checkbox is cleared
they will be overwritten with the values from the
downloaded project with one exception:
If there are no changes to any of the variable’s
attributes and Send modified project files is used,
the value from XBuilder will not be sent to the
device.
31.3
Public constants
Public constants will retain their value and disregard
the value in the downloaded project. The value of
public constants cannot be modified from the Menta
editor.
Schedules
Schedules will be overwritten with the data from the
XBuilder project. If a local modification has been
made to a schedule, those changes can be loaded
into the XBuilder project, using the Get from Target, Get online changes command. This command
will overwrite changes done in XBuilder.
Upload and Download of Parameters
This function was introduced in TAC Vista version 5.1.2. Only when it
is used with a Xenta 700 version 5.1.2 or higher can it be expected to
work with full functionality.
In Vista Workstation, when you right-click on a Xenta 700, you see the
two commands “Upload Parameters” and “Download Parameters”,
similar to what has always been available for Xenta 280/300/401.
Selecting one of the commands brings you to a window where you can
select to upload/download parameters from the Xenta 700 and also from
the Xenta devices (280/300/401) connected to the LonWorks port of the
Xenta 700. The functionality described applies to Xenta 700 only.
Upload Parameters will copy the current value of all the parameters
from the Xenta 700 to the Vista data base.
Download Parameters will download the value of all parameters from
the Vista database to the Xenta 700.
The following parameters are included:
•

•
Public Blocks
•
Xenta 700 variables
•
Times and dates of all Schedules’ events
When working with Xenta 700 in the Menta editor, the current values
from the Vista data base are not shown, unlike Xenta 280/300/401,
where the most recently uploaded values are shown in the Menta editor.
With Xenta 700, the values shown are those that have been entered into
Menta, which may differ from the values in the Xenta 700 device and
Vista Data base, depending of which changes, uploads and downloads,
have been done.
31.3.1
Parameter Download, Public Blocks
When downloading parameters from Vista, the Public Block output values are overwritten. This has consequences for some blocks as
described below.
Public PVB, PVI and PVR. Download parameters will write values to
the output, and that value will also be copied to the InitValue of the
block. That is normally the desired behavior, but it may be important to
be aware of the fact.
Public ACCUM; INTEG and RT. Also in this case, download parameters will write values to the output, which means the current values will
be overwritten. This is normally not the desired behavior. Depending on
what you want to achieve, the overwriting is possible to avoid by using
additional blocks, and consider which blocks should have the Public
checkboxes set and which should not.
31.4
Value Modifications
The first time Menta Constants, function blocks and Xenta 700 variables are downloaded they will get the value entered as InitValue in
Menta, or XBuilder respectively. From that moment on, there are
restrictions regarding how the values can be modified, depending on
type and the Public and Backup settings.
31.4.1
Menta Constants
Public Constants can be changed, using local modification, but not from
the Menta editor. Value changes done in the Menta editor will be disregarded when they are downloaded.
Menta Constants that are not public can only be changed from the
Menta editor.

32 Changing the Receive Timer Value
Changing the Receive Timer Value
TAC Vista Workstation has a default value for the receive timer for the
communication in a LonWorks network. This value is also in force for
the Xenta Server.
32.1
Changing the Receive Timer Value in TAC Vista
Workstation
When the Xenta Server is a subsystem to TAC Vista Workstation, the
default value for the receive timer (24576 ms) is often too long for maintaining good communication when many Xenta I/O modules are connected to the Xenta Server.
In such cases, the value has to be decreased until satisfying communication is achieved.
To change the receive timer value in TAC Vista Workstation
1
In TAC Vista Workstation, right-click the required LonWorks Network in the Xenta Server.
2
Click Properties.
3
In the LonWorks Networks dialog, click the Timers tab.

5
Click OK.
The new value will automatically be in force in the XBuilder project or
in a Xenta Server online in the system.
32.2
Changing the Receive Timer Value in the TAC
XBuilder Project
When the Xenta Server is used as a stand-alone system, that is not connected to a TAC Vista Workstation, you are recommended to make sure
that the receive timer value in the XBuilder project has a necessary low
value.
To change the receive timer value in the TAC XBuilder
project
1
In the Network pane, click the LON network.
2
In the properties pane, under File Transfer Timers, in the
Receive Timer property list, click the required value.
The new value will be in force when the project has been down-loaded
to the Xenta Server.
