OVERVIEW
This section contains specific information pertaining to the installation
of the Model 3051 Transmitter with FOUNDATION fieldbus.
SAFETY MESSAGES
Instructions and procedures in this section may require special
precautions to ensure the safety of the personnel performing the
operations. Information that raises potential safety issues is indicated
by a warning symbol ( ). Please refer to the following safety messages
before performing an operation preceded by this symbol.
Warnings
Explosions can result in death or serious injury.
•
Do not remove the transmitter covers in explosive environments when the
circuit is alive.
•
Both transmitter covers must be fully engaged to meet
explosionproof requirements.
•
Verify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
Electrical shock can result in death or serious injury.
•
Avoid contact with the leads and terminals.
Process leaks could result in death or serious injury.
•
Install and tighten all four flange bolts before applying pressure.
•
Do not attempt to loosen or remove flange bolts while the transmitter is
in service.
Replacement equipment or spare parts not approved by Rosemount Inc. for use
as spare parts could reduce the pressure retaining capabilities of the transmitter
and may render the instrument dangerous.
•
Use only bolts supplied with the Model 3051 or sold by Rosemount Inc. as
spare parts for the Model 3051.

Rosemount Model 3051 Transmitter with FOUNDATIONTM fieldbus
GENERAL
CONSIDERATIONS
Measurement accuracy depends upon proper installation of the
transmitter and impulse piping. Mount the transmitter close to the
process and use a minimum of piping to achieve best accuracy. Keep in
mind the need for easy access, personnel safety, practical field
calibration, and a suitable transmitter environment. Install the
transmitter to minimize vibration, shock, and temperature fluctuation.
IMPORTANT
Install the enclosed pipe plug in unused conduit openings with a
minimum of five threads engaged to comply with explosionproof
requirements. The transmitter is shipped with the plug installed on
transmitters ordered with CSA explosionproof approval.
MECHANICAL
CONSIDERATIONS
Figures 2-1 through 2-5 on pages 2-3 through 2-6 show dimensional
drawings of Model 3051 transmitters. Figure 2-7 on page 2-9 shows
installation examples. Figures 2-8 through 2-11 on pages 2-12 through
2-14 show dimensional drawings of mounting brackets.
NOTE
For Model 3051CD0 and 3051CD1, mount the transmitter solidly to
prevent tilting. A tilt in the physical transmitter may cause a zero shift
in the transmitter output.
NOTE
For steam service, do not blow down impulse piping through the
transmitter. Flush the lines with the blocking valves closed and refill
the lines with water before resuming measurement.
NOTE
When the transmitter is mounted on its side, position the Coplanar
flange to ensure proper venting or draining. Mount the flange as shown
in Figure 2-7 on page 2-9, keeping drain/vent connections on the bottom
for gas service and on the top for liquid service.
NOTE
The Model 3051 transmitter incorporates two independent seals
between the process connection and the conduit connection.

NOTE: Dimensions are in inches (millimeters).
Mounting
The Model 3051C Pressure Transmitter weighs 5.8 lbs (2,6 kg) without
additional options. Optional mounting brackets available with the
Model 3051 allow mounting to a panel, wall, or 2-inch pipe. The B4
Bracket Option for use with the Coplanar flange and the Model 3051T
is 316 SST with 316 SST bolts. Figures 2-8 and 2-9 on pages 2-12 and
2-13 show bracket dimensions and mounting configurations for the
B4 Option.
Bracket options B1, B2, B3, B7, B8, and B9 are sturdy polyurethane
painted carbon steel brackets designed for use in pipe or panel
mounting the traditional flange (H2, H3, H4, or H7 option). The B1–B3
brackets have carbon steel bolts, while the B7–B9 brackets have
stainless steel bolts. Bracket options BA and BC are stainless steel with
stainless steel bolts. Dimensionally, these brackets are identical to the
B1–B3 brackets used with the Rosemount Model 1151 Pressure
Transmitter except for the length of the bolts used to mount the
transmitter to the bracket. When installing the transmitter to one of
the mounting brackets, torque the bolts to 125 inch-pounds.
2-7
Rosemount Model 3051 Transmitter with FOUNDATIONTM fieldbus
NOTE
The transmitter is calibrated in an upright position at the factory. If
you mount the transmitter in any other position, the zero point will
shift by an amount equivalent to the liquid head caused by the varied
mounting position. Execute a zero sensor trim to compensate for
mounting position effects, see page D-2.
Mounting Requirements
Refer to Figure 2-7 for examples of the following mounting
configurations:
Liquid Flow Measurement
• Place taps to the side of the line to prevent sediment deposits on
the transmitter’s process isolators.
• Mount the transmitter beside or below the taps so gases can vent
into the process line.
• Mount drain/vent valve upward to allow gases to vent.
Gas Flow Measurement
• Place taps in the top or side of the line.
• Mount the transmitter beside or above the taps so liquid will
drain into the process line.
Steam Flow Measurement
• Place taps to the side of the line.
• Mount the transmitter below the taps to ensure that the impulse
piping will stay filled with condensate.
• Fill impulse lines with water to prevent the steam from
contacting the transmitter directly and to ensure accurate
measurement at start-up.
NOTE
In steam or other elevated temperature services, it is important that
temperatures at the coplanar process flanges not exceed 250 °F (121 °C)
for transmitters with silicone fill or 185 °F (85 °C) for inert fill. In
vacuum service, these temperature limits are reduced to 220 °F
(104 °C) for silicone fill and 160 °F (71 °C) for inert fill. Models 3051L,
and the traditional flange allow higher temperatures.

Flow
Flow
Impulse Piping
3051-3031A03A, B03A, C03A
Flow
The piping between the process and the transmitter must accurately
transfer the pressure to obtain accurate measurements. There are five
possible sources of error: pressure transfer, leaks, friction loss
(particularly if purging is used), trapped gas in a liquid line, liquid in a
gas line, and density variations between the legs.
The best location for the transmitter in relation to the process pipe
depends on the process itself. Use the following guidelines to determine
transmitter location and placement of impulse piping:
• Keep impulse piping as short as possible.
• For liquid service, slope the impulse piping at least 1 inch per foot
(8 cm per m) upward from the transmitter toward the
process connection.
• For gas service, slope the impulse piping at least 1 inch per foot
(8 cm per m) downward from the transmitter toward the
process connection.
• Avoid high points in liquid lines and low points in gas lines.
• Make sure both impulse legs are the same temperature.
• Use impulse piping large enough to avoid friction effects
and blockage.
• Vent all gas from liquid piping legs.
• When measuring a fluid, fill both piping legs to the same level.
• When purging, make the purge connection close to the process
taps and purge through equal lengths of the same size pipe.
Avoid purging through the transmitter.
• Keep corrosive or hot (above 250 °F [121 °C]) process material out
of direct contact with the sensor module and flanges.
• Prevent sediment deposits in the impulse piping.
• Keep the liquid head balanced on both legs of the impulse piping.
• Avoid conditions that might allow process fluid to freeze within
the process flange.

Rosemount Model 3051 Transmitter with FOUNDATIONTM fieldbus
Process Connections
Model 3051 process connections on the transmitter flange are
1
/4-18 NPT. Flange adapter unions with 1/2–14 NPT connections are
supplied as standard. The threads are Class 2; use your plant-approved
lubricant or sealant when making the process connections. The process
connections on the transmitter flange are on 21/8-inch (54 mm) centers
to allow direct mounting to a three-valve or five-valve manifold. Rotate
one or both of the flange adapters to attain connection centers of
2 inches (51 mm), 21/8 inches (54 mm), or 21/4 inches (57 mm). See
page 2-10 for information on the Model 3051T process connection.
Install and tighten all four flange bolts before applying pressure, or
process leakage will result. When properly installed, the flange bolts
will protrude through the top of the module housing. Do not attempt to
loosen or remove the flange bolts while the transmitter is in service.
To install adapters to a Coplanar flange, perform the following
procedure:
1. Remove the flange bolts.
2. Leaving the flange in place, move the adapters into position with
the O-ring installed.
3. Clamp the adapters and the Coplanar flange to the transmitter
module using the larger of the bolts supplied.
4. Tighten the bolts. Refer to “Mounting Bolts” on page 2-15 for
torque specifications.
Failure to install proper flange adapter O-rings can cause process leaks, which can
result in death or serious injury.
Each style of Rosemount flange adapters requires a unique O-ring, as shown below.
Flange adapters are distinguished by their unique grooves.

See “Safety Messages” on page 2-1 for complete warning information.
2-10
Installation
When compressed, Teflon® O-rings tend to cold flow, which aids in their
sealing capabilities. Whenever you remove flanges or adapters, visually
inspect the Teflon O-rings. Replace them if there are any signs of
damage, such as nicks or cuts. If they are undamaged, you may reuse
them. If you replace the O-rings, retorque the flange bolts after
installation to compensate for cold flow. Refer to the process sensor body
reassembly procedure in Section 7: Maintenance.

Housing Rotation
3051-3051TF6D
Do not apply torque directly to the sensor module. Rotation between the sensor module
and the process connection can damage the electronics. To avoid damage, apply torque
only to the hex-shaped process connection.
The electronics housing can be rotated up to 180 degrees (left or right)
to improve field access or to better view the optional LCD meter. To
rotate the housing, perform the following procedure:
1. Loosen the housing rotation set screw using a 9/64-in. hex wrench.
NOTE
Do not rotate the housing more than 180 degrees without first
performing a disassembly procedure (see “Disassembly Procedures” on
page 7-2). Over-rotation will sever the electrical connection between the
sensor module and the electronics module.
2. Turn the housing up to 180 degrees to the left or right of its
original (as shipped) position.
3. Retighten the housing rotation set screw.

Model 305 Installation Procedure
To install a Model 305 Integral mainfold to a Model 3051 transmitter
follow the procedure below.
1. Inspect the Teflon (PTFE) sensor module O-rings. If the O-rings
are undamaged, reusing them is recommended. If the O-rings
have nicks, cuts, or other damage, replace them with new
O-rings.
IMPORTANT
Do not scratch or deface the O-ring grooves or the surface of the
isolating diaphragm while you remove the O-rings.
2. Install the integral manifold on the sensor module:
a. Align the manifold and sensor module by inserting and
finger-tightening the four 2.25-inch (57 mm) manifold bolts.
b. Tighten the bolts incrementally in a cross-pattern until each of
them reaches the initial torque value (See Table 2-2,
depending upon the bolt material).
c. Tighten the bolts incrementally again until each of them
reaches the final torque value (See Table 2-2, depending upon
the bolt material).
3. If the Teflon (PTFE) sensor module O-rings have been replaced,
the flange bolts should be re-tightened after installation to
compensate for cold flow of the O-rings.
4. Install the drain/vent valves:
a. Apply two complete turns of sealing tape to the valve body
threads (with the open end of the threads pointing toward you,
wrap the tape clockwise beginning at the edge closest to you).
b. Tighten the the valve body into the manifold to 250 in-lb
(28,3 N-m).
c. Orient the opening of the valve so that once the transmitter is
installed the valve opening will point to the ground and away
from personnel when the valve is opened.
d. Tighten the valve bonnet and stem onto the valve body to
70 ± 10 in-lb (7,9 ± 1,1 N-m).
e. Repeat a-d for each drain/vent valve.
NOTE
Perform a zero trim on the transmitter/manifold assembly after you
combine them to eliminate any mounting effects.
See “Safety Messages” on page 2-1 for complete warning information.

Model 306 Integral
Manifolds
The Model 306 integral manifold is for use only with a Model
3051T transmitter.
Model 306 Installation
To install a Model 306 Integral mainfold to a Model 3051 transmitter
follow the procedure below.
1. Apply two complete turns of sealing tape to the manifold threads
(with the open end of the threads pointing toward you, wrap the
tape clockwise beginning at the edge closest to you).
2. Turn the manfiold threads into the sensor module to leak tight.
Tagging
Commissioning (Paper) Tag
When commissioning more than one device on a fieldbus segment, it
can be difficult to identify which device is at a particular location. A
removable tag provided with the transmitter can aid in this process by
linking the Device ID and a physical location. TheDevice ID is a unique
code that identifies a particular device in the absence of a device tag.
The device tag is used by the customer as an operational identification
for the device and is usually defined by the Piping and Instrumentation
Diagram (P & ID).
The installer should note the physical location in both places on the
removable commissioning tag and tear off the bottom portion. This
should be done for each device on the segment. The bottom portion of
the tags can be used for commissioning the segment in the control
system, providing a direct link between the Device ID and the tag
location.

ELECTRICAL
CONSIDERATIONS
Proper electrical installation is necessary to prevent errors due to
grounding and electrical noise. Shielded, twisted pair cable should be
used for best results in electrically noisy environments.
Power Supply
The transmitter requires between 9 and 32 V dc to operate and provide
complete functionality. The dc power supply should provide power with
less than 2% ripple.
Power Conditioner
A fieldbus segment requires a power conditioner to isolate the power
supply filter and decouple the segment from other segments attached to
the same power supply.
Field Wiring
All power to the transmitter is supplied over the signal wiring. Signal
wiring should be shielded, twisted pair for best results. Do not run
unshielded signal wiring in conduit or open trays with power wiring or
near heavy electrical equipment. Do not remove the transmitter cover
in explosive atmospheres when the circuit is alive.
NOTE
Do not apply high voltage (e.g. ac line voltage) to the transmitter
terminals. Abnormally high voltage can damage the unit. (Transmitter
power terminals are rated to 32 V dc.)
Hazardous Locations
The Model 3051 has an explosionproof housing and circuitry suitable
for intrinsically safe and non-incendive operation. Individual
transmitters are clearly marked with a tag indicating the certifications
they carry. See Section 6 Specifications and Reference Data for specific
approval categories, and see Section 8 Approval Drawings for
installation drawings.
NOTE
Once a device labeled with multiple approval types is installed, it
should not be reinstalled using any of the other labeled approval types.
To ensure this, the approval label should be permanently marked to
distinguish the used from the unused approval type(s).
Power Connections
2-22
Use ordinary copper wire of sufficient size to ensure that the voltage
across the transmitter power terminals does not go below 9 V dc. To
power the transmitter, connect the power leads to the terminals marked
“FIELDBUS WIRING” as shown in Figure 2-17. The power terminals
are polarity insensitive, which means the electrical polarity of the
power leads does not matter when connecting to the power terminals.
When wiring to screw terminals, the use of crimped lugs is
recommended. Tighten the terminal screws to ensure adequate contact.

Rosemount Model 3051 Transmitter with FOUNDATIONTM fieldbus
Grounding
Neither conductor of the fieldbus segment can be grounded. Grounding
out one of the signal wires will shut down the entire fieldbus segment.
Shielded Wire
Recommended grounding techniques for shielded wire usually call for a
single grounding point for each shielded wire to avoid creating a ground
loop. The ground point is typically at the power supply.
Grounding the
Transmitter Housing
The transmitter housing should always be grounded in accordance with
national and local electrical codes. The most effective transmitter case
grounding method is direct connection to earth ground with minimal
impedance. Methods for grounding the transmitter case include:
• Internal Ground Connection: The Internal Ground
Connection screw is inside the FIELD TERMINALS side of the
electronics housing. This screw is identified by a ground symbol
( ), and is standard on all Model 3051 transmitters.
• External Ground Assembly: This assembly is included with
the optional transient protection terminal block (Option Code
T1), and it is included with CESI/CENELEC Flameproof
Certification (Option Code E8), BASEEFA/CENELEC Intrinsic
Safety Certification (Option Code I1), and BASEEFA/CENELEC
Type N Certification (Option Code N1). The External Ground
Assembly can also be ordered with the transmitter (Option Code
V5), or as a spare part (03031-0398-0001).
NOTE
Grounding the transmitter case using the threaded conduit connection
may not provide a sufficient ground. The transient protection terminal
block (Option Code T1) does not provide transient protection unless the
transmitter case is properly grounded. Use the above guidelines to
ground the transmitter case. Do not run the transient protection
ground wire with signal wiring as the ground wire may carry excessive
current if a lightning strike occurs.
Surges/Transients
The transmitter will withstand electrical transients of the energy level
usually encountered in static discharges or induced switching
transients. However, high-energy transients, such as those induced in
wiring from nearby lightning strikes, can damage the transmitter.
Optional Transient
Protection Terminal Block
The transient protection terminal block can be ordered as an installed
option (Option Code T1 in the transmitter model number) or as a spare
part to retrofit existing Model 3051 transmitters in the field. The spare
part number is 03031-0332-2002. The symbol shown in Figure 2-18
identifies the transient protection terminal block.
NOTE
The fieldbus physical layer specification requires transmitter
communication during extreme operating conditions of 250 Vrms
common mode signal. The transient terminal block was designed to
limit common mode voltages to 90 V and cannot be used in these
extreme operating conditions.
2-24
Installation
Figure 2-18. Transient Protection
Terminal Block.
Transient Protection Symbol
Installation
When the transient protection terminal block is ordered as a spare part,
it must be installed in place of the standard terminal block inside the
transmitter housing. See “Remove the Terminal Block” on page 7-2.
NOTE
The transient protection terminal block provides transient protection
only if the transmitter housing is properly grounded. See “Grounding
the Transmitter Housing” on page 2-24.
Performance
The transient protection terminal block increases the ability of the
Model 3051 transmitter to withstand electrical transients induced by
lightning, welding, or heavy electrical equipment. With the transient
protection block installed, the Model 3051 transmitter meets the
standard performance specifications as outlined in this product
manual. In addition, the transient protection circuitry meets IEEE
Standard 587, Category B and IEEE Standard 472, Surge Withstand
Capability.
Jumpers
Security
After you configure the transmitter, you may want to protect the
configuration data from unwarranted changes. Each transmitter is
equipped with a security jumper that can be positioned “ON” to prevent
the accidental or deliberate change of configuration data. The jumper is
located on the front side of the electronics module and is labeled
SECURITY (see Figure 2-19).
Simulate
The simulate jumper is used in conjunction with the Analog Input (AI)
function block. This switch is used to simulate the measurement and is
used as a lock-out feature for the AI function block. To enable the
simulate feature, insert the jumper across “ENABLE” (see Figure 2-19)
while the transmitter is powered.
NOTE
When power is cycled to the transmitter, simulate is automatically
disabled regardless of the position of the jumper. This prevents the
transmitter from being accidentally left in simulate mode. Therefore, to
enable the simulate feature, the jumper must be inserted after power is
applied to the transmitter.

ENVIRONMENTAL
CONSIDERATIONS
The Model 3051 can tolerate a wide range of applications. To optimize
performance, mount the transmitter to minimize ambient temperature
changes, to avoid vibration and mechanical shock, and to avoid external
contact with corrosive materials. Section 6: Specifications and
Reference Data lists the transmitter temperature operating limits.
Access Requirements
When choosing an installation location and position, take into account
the need for access to the transmitter.
Process Flange Orientation
Mount the process flanges with sufficient clearance for process
connections. For safety reasons, place the drain/vent valves so the
process fluid is directed away from technicians when the vents are
used. In addition, consider the possible need for a testing or calibration
input.
Housing Rotation
See “Housing Rotation” on page 2-11.
Terminal Side of
Electronics Housing
Mount the transmitter so that the terminal side is accessible. A
0.75-inch (19 mm) clearance is required for cover removal. Install the
provided conduit plug on the unused side of the conduit opening.
Circuit Side of
Electronics Housing
Provide 3 inches (76.2 mm) clearance for cover removal. Three inches of
clearance is required for cover removal if a meter is installed.
Cover Installation
Always install the electronics housing covers metal-to-metal to ensure a
proper seal.

Overview
Each FOUNDATION fieldbus configuration tool or host device has a
different way of displaying and performing configurations. Some will
use Device Descriptions (DD) and DD Methods to make configuration
and displaying of data consistent across host platforms. Since there is
no requirement that a configuration tool or host support these features,
this section will describe how to reconfigure the device manually.
Appendix D: Operation with Fisher-Rosemount® DeltaV™ shows the
Delta V implementation of these common functions.
(1)
The Device Revision number can be found in the Resource Block
parameter “DEV_REV.”

Rosemount Model 3051 Transmitter with FOUNDATIONTM fieldbus
Assigning Device Tag and
Node Address
The transmitter is shipped with a blank tag and a temporary address
(unless specifically ordered with both) to allow a host to automatically
assign an address and a tag. If the tag or address needs to be changed,
use the features of the configuration tool. The tools basically do the
following:
1. Change tag to new value.(1)
2. Change address to new address.
When the device is at a temporary address, only the tag and address
can be changed or written to. The resource, transducer, and function
blocks are all disabled.
Pressure Specific Block
Configuration
AI Block
NOTE
As a general convention, parameters within blocks are referred to in the
following manner: <block ID>.<parameter>, where <block ID> is the
default name of the block (such as TB for transducer block), and
<parameter> is the block parameter (such as CAS_IN).
For example AI1.OUT_D refers to the OUT_D parameter of Analog
Input block number 1.
Unless otherwise specified, the block referred to is that of the Model
3051 transmitter rather than a block in another instrument.
The Analog Input (AI) function block provides the primary interface of
the measurement to the control and/or monitoring systems. The
interface between the AI block and the Transducer Block (TB) is
basically through 3 parameters. The CHANNEL parameter defines
which transducer block measurement is used by the AI block. The
preconfigured values are AI1.CHANNEL = 1 (P) and AI2.CHANNEL =
2 (ST). The second parameter is the XD_SCALE.UNITS_INDEX. The
configuration is set at the factory per user calibration units.
Finally, since the measurement from the transducer block is in the
correct units, L_TYPE is configured as Direct. Please note the that
these parameters must be changed in the following order:
1. Set MODE_BLK.TARGET to OOS
2. CHANNEL
3. XD_SCALE.UNITS_INDEX
4. L_TYPE
5. Set MODE_BLK.TARGET to AUTO
NOTE
Please refer to Appendix B: Analog Input (AI) Function Block for more
details on configuring and troubleshooting the AI block.

For your convenience, the transmitter has been supplied with a removable tag to aid in
the commissioning process of multiple devices (see Tagging on page 2-21).
Operation
General Block
Configuration
In general, only the Transducer (TB) and Analog Input (AI) blocks have
configurations for pressure-specific parameters. All other function
blocks are configured by linking the AI block to other blocks to be used
for control and/or monitoring applications. See the appropriate function
block Appendix for specific application examples.
Configuring Links and
Scheduling Block
Execution
Without configuring the links between blocks and scheduling the blocks
to execute in proper order, the application will not work correctly. Most
hosts and/or configuration tools make this task a simple matter by
using a Graphical User Interface (GUI).
Measurement Application:
When using the Model 3051 transmitter, configure the setup and
links/schedules according to Figure 3-2.

The transducer block supports two modes of operation as defined by the
MODE_BLK Parameter:
Automatic (Auto)—The channel outputs reflect the analog
input measurement.
Out of Service (OOS)—Channel outputs status is set to Bad: Out of
Service for each channel. The BLOCK_ERR parameter shows Out of
Service. In this mode, you can make changes to all configurable
parameters. The target mode of a block may be restricted to one or more
of the supported modes.

Rosemount Model 3051 Transmitter with FOUNDATIONTM fieldbus
Alarm Detection
Alarms are not generated by the transducer block. By correctly
handling the status of the channel values, the down stream block (AI)
will generate the necessary alarms for the measurement. The error that
generated this alarm can be determined by looking at BLOCK_ERR
and XD_ERROR and TB_DETAILED_STATUS.
Status Handling
Normally, the status of the output channels reflects the status of the
measurement value, the operating condition of the measurement
electronics, and any active alarm condition.
In Auto mode, PRIMARY_VALUE reflects the value and status quality
of the output channels.
Methods
Sensor Calibration
In order to calibrate the sensor, the following steps are performed by
the user calibration method:
1. Set MODE_BLK.TARGET = OOS.
2. Apply desired pressure (low pressure); allow to stabilize.
Pressure applied must be between range limits defined in
PRIMARY_VALUE_RANGE.
3. Set CAL_POINT_LO to applied pressure.
4. Apply desired pressure (high pressure); allow to stabilize.
Pressure applied must be between range limits defined in
PRIMARY_VALUE_RANGE and greater than CAL_POINT_LO
+ CAL_MIN_SPAN.
5. Set CAL_POINT_HI to applied pressure.
6. Set SENSOR_CAL_DATE to current date.
7. Set SENSOR_CAL_WHO to person responsible for calibration.
8. Set SENSOR_CAL_LOC to calibration location.
9. Set MODE_BLK.TARGET = AUTO.

The resource block supports two modes of operation as defined by the
MODE_BLK parameter:
• Automatic (Auto) The block is processing its normal
background memory checks.
• Out of Service (OOS) The block is not processing its tasks.
When the resource block is in OOS, all blocks within the resource
(device) are forced into OOS. The BLOCK_ERR parameter shows
Out of Service. In this mode, you can make changes to all
configurable parameters. The target mode of a block may be
restricted to one or more of the supported modes.
Alarm Detection
A block alarm will be generated whenever the BLOCK_ERR has an
error bit set. The types of block error for the resource block are
defined above.
A write alarm is generated whenever the WRITE_LOCK parameter is
cleared. The priority of the write alarm is set in the WRITE_PRI
parameter:
Alarms are grouped into five levels of priority

When you buy a Rosemount® transmitter, you can be confident you are
getting a transmitter that not only meets, but most likely greatly exceeds,
the published specifications. Our advanced manufacturing techniques
and implementation of statistical process control provides specification
conformance to at least 3s(1).
Our commitment to continual improvement ensures that product
design, reliability and performance get better every year. By focusing on
our manufacturing process, we are able to reduce product variability,
and our specifications have improved accordingly. The Model 3051
specifications have improved every year since introduction in 1988.
While most of these changes do not affect its outward appearance, all
of the changes increase the value of each Model 3051 shipped. The
transmitters that Rosemount Inc. ships tomorrow will be even better than
units shipped today. The result: you always get the best possible
transmitter from Rosemount Inc.

Remove the Transmitter
from Service
NOTE
Once you have determined a transmitter to be inoperable, remove it
from service.
Be aware of the following:
3051-052AB
• Isolate and vent the process from the transmitter before
removing the transmitter from service.
• Remove all electrical leads and conduit. Avoid grounding out the
lead wires if other devices on the fieldbus segment
are operational.
• Detach the process flange by removing the four flange bolts and
the two alignment screws that secure it.
• Do not scratch, puncture, or depress the isolating diaphragms.
• Clean isolating diaphragms with a soft rag and a mild cleaning
solution, and rinse with clear water.
• Whenever you remove the process flange or flange adapters,
visually inspect the Teflon O-rings. Replace the O-rings if they
show any signs of damage, such as nicks or cuts. If they are
undamaged, you may reuse them.
The Model 3051C transmitter is attached to the process connection by
four bolts and two cap screws. Remove the four bolts and separate the
transmitter from the process connection manifold or flange. You can
leave the process connection in place and ready for re-installation.
The Model 3051T is attached to the process by a single hex nut
process connection. Loosen the hex nut to separate the transmitter
from the process.
Remove the Terminal Block
Electrical connections are located on the terminal block in the
compartment labelled “FIELD TERMINALS.”
Loosen the two small screws located at the 9 o'clock and 4 o'clock
positions, and pull the entire terminal block out to remove it.
Remove the
Electronics Board
The transmitter electronics board is located in the compartment
opposite the terminal side. To remove the electronics board perform the
following procedure:

housing. The electronics board is electrostatically sensitive;
observe handling precautions for static-sensitive components.
NOTE
If you are disassembling a transmitter with a LCD meter, loosen the
two captive screws that are visible on the right and left side of the
meter display. The two screws anchor the LCD meter to the electronics
board and the electronics board to the housing.
3051-055AB
3. Slowly pull the electronics board out of the housing. With the two
captive screws free of the transmitter housing, only the sensor
module ribbon cable holds the board to the housing.
3051-056AB
4. Disconnect the sensor module ribbon cable to release the
electroncis board from the transmitter.
Remove the Sensor
Module from the
Electronics Housing
3051-057AB
1. Carefully tuck the cable connector completely inside of the

internal shroud and cable through the housing and into the
external shroud.
4. Turn the housing clockwise the fasten it to the module.
7-4
Maintenance
IMPORTANT
To prevent damage to the cable connector, watch the cable and shroud
as you attach the housing to the module. Make sure the cable connector
does not slip out of the internal shroud and begin to rotate with the
housing. Reinsert the cable connector into the shroud if it escapes
before the housing is fully fastened.
5. Thread the housing completely onto the sensor module. The
housing must be no more than one full turn from flush with the
sensor module to comply with explosionproof requirements.
3051-059AB
6. Tighten the housing rotation set screw using a 9/64-inch
hex wrench.
Attach the

4. Replace the electronics housing cover. The transmitter covers
must be engaged metal-to-metal to ensure a proper seal and to
meet explosionproof requirements.
Reassemble the Process
Connection to the
Sensor Module
1. Visually inspect the Teflon (PTFE) sensor module O-rings. If the
O-rings are undamaged, you may reuse them. If the O-rings show
signs of damage, such as nicks or cuts, or if there is any doubt
about their ability to seal properly, replace them with
new O-rings.
NOTE
If you are replacing the O-rings, be careful not to scratch the O-ring
grooves or the surface of the isolating diaphragm when removing the
damaged O-rings.
2. Install the process flange on the sensor module. To hold the
process flange in place, install the two hex head alignment
screws. These screws are not pressure retaining and need only be
finger tight. Do not overtighten; this will affect the module/flange
alignment.
3. Install the appropriate flange bolts.
a. IF the installation requires a 1/4–18 NPT mounting, THEN use
four 1.75-inch flange bolts. Go to Step f.
b. IF the installation requires a 1/2–14 NPT mounting, THEN use
four 2.88-inch process flange/adapter bolts. EXCEPTION: For
gage pressure configurations, use two 2.88-inch bolts and two
1.75-inch bolts. Go to Step d.
c. IF the installation uses a three-valve manifold (differential
pressure applications only), THEN use four 2.25-inch manifold
flange bolts. Go to Step e.
d. Hold the flange adapters and adapter O-rings in place while
finger-tightening the bolts. Go to Step g.
e. Align the process flange with the three-valve manifold.
f. Finger tighten the bolts.
g. Tighten the bolts to the inital torque value using a crossed
pattern. See Table 7-1 for appropriate torque values.
h. Tighten the bolts to the final torque value using a crossed
pattern. See Table 7-1 for appropriate torque values. When
fully tightened, the bolts should extend through the top of the
module housing.
i. If the installation uses a three-valve manifold, then install
flange adapters on the process end of the manifold using the
1.75-inch flange bolts supplied with the transmitter.
See “Safety Messages” on page 7-1 for complete warning information.

FOUNDATION™ fieldbus
Technology and Fieldbus
Function Blocks
OVERVIEW
This section introduces fieldbus systems that are common to all
fieldbus devices.
INTRODUCTION
A fieldbus system is a distributed system composed of field devices and
control and monitoring equipment integrated into the physical
environment of a plant or factory. Fieldbus devices work together to
provide I/O and control for automated processes and operations. The
Fieldbus Foundation provides a framework for describing these systems
as a collection of physical devices interconnected by a fieldbus network.
One of the ways that the physical devices are used is to perform their
portion of the total system operation by implementing one or more
function blocks.
Function Blocks
Function blocks within the fieldbus device perform the various
functions required for process control. Because each system is different,
the mix and configuration of functions are different. Therefore, the
Fieldbus FOUNDATION has designed a range of function blocks, each
addressing a different need.
Function blocks perform process control functions, such as analog input
(AI) and analog output (AO) functions as well as
proportional-integral-derivative (PID) functions. The standard function
blocks provide a common structure for defining function block inputs,
outputs, control parameters, events, alarms, and modes, and combining
them into a process that can be implemented within a single device or
over the fieldbus network. This simplifies the identification of
characteristics that are common to function blocks.
The Fieldbus FOUNDATION has established the function blocks by
defining a small set of parameters used in all function blocks called
universal parameters. The FOUNDATION has also defined a standard set
of function block classes, such as input, output, control, and calculation
blocks. Each of these classes also has a small set of parameters
established for it. They have also published definitions for transducer
blocks commonly used with standard function blocks. Examples include
temperature, pressure, level, and flow transducer blocks.
The FOUNDATION specifications and definitions allow vendors to add
their own parameters by importing and subclassing specified classes.
This approach permits extending function block definitions as new
requirements are discovered and as technology advances.
A-1
Rosemount Model 3051 Transmitter with FOUNDATIONTM fieldbus
Figure A-1 illustrates the internal structure of a function block. When
execution begins, input parameter values from other blocks are
snapped-in by the block. The input snap process ensures that these
values do not change during the block execution. New values received
for these parameters do not affect the snapped values and will not be
used by the function block during the current execution.

Status
Once the inputs are snapped, the algorithm operates on them,
generating outputs as it progresses. Algorithm executions are
controlled through the setting of contained parameters. Contained
parameters are internal to function blocks and do not appear as normal
input and output parameters. However, they may be accessed and
modified remotely, as specified by the function block.
Input events may affect the operation of the algorithm. An execution
control function regulates the receipt of input events and the
generation of output events during execution of the algorithm. Upon
completion of the algorithm, the data internal to the block is saved for
use in the next execution, and the output data is snapped, releasing it
for use by other function blocks.
A block is a tagged logical processing unit. The tag is the name of the
block. System management services locate a block by its tag. Thus the
service personnel need only know the tag of the block to access or
change the appropriate block parameters.
Function blocks are also capable of performing short-term data
collection and storage for reviewing their behavior.
Device Descriptions
Device Descriptions are specified tool definitions that are associated
with the function blocks. Device descriptions provide for the definition
and description of the function blocks and their parameters.
To promote consistency of definition and understanding, descriptive
information, such as data type and length, is maintained in the device
description. Device Descriptions are written using an open language
called the Device Description Language (DDL). Parameter transfers
between function blocks can be easily verified because all parameters
are described using the same language. Once written, the device
description can be stored on an external medium, such as a CD-ROM or
diskette. Users can then read the device description from the external
medium. The use of an open language in the device description permits
A-2
FIELDBUS_0012
Figure A-1. Function Block
Internal Structure.
Foundation™ fieldbus Technology and Fieldbus Function Blocks
interoperability of function blocks within devices from various vendors.
Additionally, human interface devices, such as operator consoles and
computers, do not have to be programmed specifically for each type of
device on the bus. Instead their displays and interactions with devices
are driven from the device descriptions.
Device descriptions may also include a set of processing routines called
methods. Methods provide a procedure for accessing and manipulating
parameters within a device.
BLOCK OPERATION
In addition to function blocks, fieldbus devices contain two other block
types to support the function blocks. These are the resource block and
the transducer block. The resource block contains the hardware specific
characteristics associated with a device. Transducer blocks couple the
function blocks to local input/output functions.
Instrument-Specific
Function Blocks
Resource Blocks
Resource blocks contain the hardware specific characteristics
associated with a device; they have no input or output parameters. The
algorithm within a resource block monitors and controls the general
operation of the physical device hardware. The execution of this
algorithm is dependent on the characteristics of the physical device, as
defined by the manufacturer. As a result of this activity, the algorithm
may cause the generation of events. There is only one resource block
defined for a device. For example, when the mode of a resource block is
“out of service,” it impacts all of the other blocks.
Transducer Blocks
Transducer blocks connect function blocks to local input/output
functions. They read sensor hardware and write to effector (actuator)
hardware. This permits the transducer block to execute as frequently as
necessary to obtain good data from sensors and ensure proper writes to
the actuator without burdening the function blocks that use the data.
The transducer block also isolates the function block from the vendor
specific characteristics of the physical I/O.
Alerts
When an alert occurs, execution control sends an event notification and
waits a specified period of time for an acknowledgment to be received.
This occurs even if the condition that caused the alert no longer exists.
If the acknowledgment is not received within the pre-specified time-out
period, the event notification is retransmitted. This assures that alert
messages are not lost.
Two types of alerts are defined for the block, events and alarms. Events
are used to report a status change when a block leaves a particular
state, such as when a parameter crosses a threshold. Alarms not only
report a status change when a block leaves a particular state, but also
report when it returns back to that state.

LINK MASTER
BASIC DEVICES AND/OR
LINK MASTER DEVICES
LAS = Link Active Scheduler
Link Active Scheduler
(LAS)
All links have one and only one Link Active Scheduler (LAS). The LAS
operates as the bus arbiter for the link. The LAS does the following:
• recognizes and adds new devices to the link.
• removes non-responsive devices from the link.
• distributes Data Link (DL) and Link Scheduling (LS) time on the
link. Data Link Time is a network-wide time periodically
distributed by the LAS to synchronize all device clocks on the
bus. Link Scheduling time is a link-specific time represented as
an offset from Data Link Time. It is used to indicate when the
LAS on each link begins and repeats its schedule. It is used by
system management to synchronize function block execution
with the data transfers scheduled by the LAS.
• polls devices for process loop data at scheduled transmission
times.
• distributes a priority-driven token to devices between scheduled
transmissions.
Any device on the link may become the LAS, as long as it is capable.
The devices that are capable of becoming the LAS are called link
master devices. All other devices are referred to as basic devices. When
a segment first starts up, or upon failure of the existing LAS, the link
master devices on the segment bid to become the LAS. The link master
that wins the bid begins operating as the LAS immediately upon
completion of the bidding process. Link masters that do not become the
LAS act as basic devices. However, the link masters can act as LAS
backups by monitoring the link for failure of the LAS and then bidding
to become the LAS when a LAS failure is detected.
Only one device can communicate at a time. Permission to communicate
on the bus is controlled by a centralized token passed between devices
by the LAS. Only the device with the token can communicate. The LAS
maintains a list of all devices that need access to the bus. This list is
called the “Live List.”
Two types of tokens are used by the LAS. A time-critical token, compel
data (CD), is sent by the LAS according to a schedule. A non-time
critical token, pass token (PT), is sent by the LAS to each device in
ascending numerical order according to address.

Foundation™ fieldbus Technology and Fieldbus Function Blocks
Device Addressing
Fieldbus uses addresses between 0 and 255. Addresses 0 through 15 are
reserved for group addressing and for use by the data link layer. For all
Fisher-Rosemount fieldbus devices addresses 20 through 35 are
available to the device. If there are two or more devices with the same
address, the first device to start will use its programmed address. Each
of the other devices will be given one of four temporary addresses
between 248 and 251. If a temporary address is not available, the device
will be unavailable until a temporary address becomes available.
Scheduled Transfers
Information is transferred between devices over the fieldbus using
three different types of reporting.
• Publisher/Subscriber: This type of reporting is used to transfer
critical process loop data, such as the process variable. The data
producers (publishers) post the data in a buffer that is
transmitted to the subscriber (S), when the publisher receives the
Compel data. The buffer contains only one copy of the data. New
data completely overwrites previous data. Updates to published
data are transferred simultaneously to all subscribers in a single
broadcast. Transfers of this type can be scheduled on a precisely
periodic basis.
• Report Distribution: This type of reporting is used to broadcast
and multicast event and trend reports. The destination address
may be predefined so that all reports are sent to the same
address, or it may be provided separately with each report.
Transfers of this type are queued. They are delivered to the
receivers in the order transmitted, although there may be gaps
due to corrupted transfers. These transfers are unscheduled and
occur in between scheduled transfers at a given priority.
• Client/Server: This type of reporting is used for
request/response exchanges between pairs of devices. Like Report
Distribution reporting, the transfers are queued, unscheduled,
and prioritized. Queued means the messages are sent and
received in the order submitted for transmission, according to
their priority, without overwriting previous messages. However,
unlike Report Distribution, these transfers are flow controlled
and employ a retransmission procedure to recover from
corrupted transfers.
Figure A-3 on page -6 diagrams the method of scheduled data transfer.
Scheduled data transfers are typically used for the regular cyclic
transfer of process loop data between devices on the fieldbus. Scheduled
transfers use publisher/subscriber type of reporting for data transfer.
The Link Active Scheduler maintains a list of transmit times for all
publishers in all devices that need to be cyclically transmitted. When it
is time for a device to publish data, the LAS issues a Compel Data (CD)
message to the device. Upon receipt of the CD, the device broadcasts or
“publishes” the data to all devices on the fieldbus. Any device that is
configured to receive the data is called a “subscriber.”

are used for things like user-initiated changes, including set point
changes, mode changes, tuning changes, and upload/download.
Unscheduled transfers use either report distribution or client/server
type of reporting for transferring data.
All of the devices on the fieldbus are given a chance to send
unscheduled messages between transmissions of scheduled data. The
LAS grants permission to a device to use the fieldbus by issuing a pass
token (PT) message to the device. When the device receives the PT, it is
allowed to send messages until it has finished or until the “maximum
token hold time” has expired, whichever is the shorter time. The
message may be sent to a single destination or to multiple destinations.

Foundation™ fieldbus Technology and Fieldbus Function Blocks
Figure A-5 shows an example of a link schedule. A single iteration of
the link-wide schedule is called the macrocycle. When the system is
configured and the function blocks are linked, a master link-wide
schedule is created for the LAS. Each device maintains its portion of the
link-wide schedule, known as the Function Block Schedule. The
Function Block Schedule indicates when the function blocks for the
device are to be executed. The scheduled execution time for each
function block is represented as an offset from the beginning of the
macrocycle start time.

Macrocycle
To support synchronization of schedules, periodically Link Scheduling
(LS) time is distributed. The beginning of the macrocycle represents a
common starting time for all Function Block schedules on a link and for
the LAS link-wide schedule. This permits function block executions and
their corresponding data transfers to be synchronized in time.

= The block output value and status
= Discrete output that signals a selected

The Analog Input (AI) function block processes field device
measurements and makes them available to other function blocks. The
output value from the AI block is in engineering units and contains a
status indicating the quality of the measurement. The measuring
device may have several measurements or derived values available in
different channels. Use the channel number to define the variable that
the AI block processes.
The AI block supports alarming, signal scaling, signal filtering, signal
status calculation, mode control, and simulation. In Automatic mode,
the block’s output parameter (OUT) reflects the process variable (PV)
value and status. In Manual mode, OUT may be set manually. The
Manual mode is reflected on the output status. A discrete output
(OUT_D) is provided to indicate whether a selected alarm condition is
active. Alarm detection is based on the OUT value and user specified
alarm limits. Figure B-1 on page -3 illustrates the internal components
of the AI function block, and Table B-1 lists the AI block parameters

The block alarm is used for all configuration, hardware, connection failure or system
problems in the block. The cause of the alert is entered in the subcode field. The first
alert to become active will set the Active status in the Status parameter. As soon as
the Unreported status is cleared by the alert reporting task, another block alert may
be reported without clearing the Active status, if the subcode has changed.
This parameter reflects the error status associated with the hardware or software
components associated with a block. It is a bit string, so that multiple errors may be
shown.
The CHANNEL value is used to select the measurement value. Refer to the
appropriate device manual for information about the specific channels available in
each device.
You must configure the CHANNEL parameter before you can configure the
XD_SCALE parameter.

Simulation
To support testing, you can either change the mode of the block to
manual and adjust the output value, or you can enable simulation
through the configuration tool and manually enter a value for the
measurement value and its status. In both cases, you must first set the
ENABLE jumper on the field device.
NOTE
All fieldbus instruments have a simulation jumper. As a safety
measure, the jumper has to be reset every time there is a power
interruption. This measure is to prevent devices that went through
simulation in the staging process from being installed with simulation
enabled.
With simulation enabled, the actual measurement value has no impact
on the OUT value or the status.

Filtering
The filtering feature changes the response time of the device to smooth
variations in output readings caused by rapid changes in input. You can
adjust the filter time constant (in seconds) using the PV_FTIME
parameter. Set the filter time constant to zero to disable the
filter feature.
Signal Conversion
You can set the signal conversion type with the Linearization Type
(L_TYPE) parameter. You can view the converted signal (in percent of
XD_SCALE) through the FIELD_VAL parameter.
100 × ( Channel Value – EU*@0% )
FIELD_VAL = -------------------------------------------------------------------------------------( EU*@100% – EU*@0% )

You can choose from direct, indirect, or indirect square root signal
conversion with the L_TYPE parameter.
Direct
Direct signal conversion allows the signal to pass through the accessed
channel input value (or the simulated value when simulation is enabled).
PV = Channel Value
Indirect
Indirect signal conversion converts the signal linearly to the accessed
channel input value (or the simulated value when simulation is
enabled) from its specified range (XD_SCALE) to the range and units of
the PV and OUT parameters (OUT_SCALE).

Analog Input (AI) Function Block
When the converted input value is below the limit specified by the
LOW_CUT parameter, and the Low Cutoff I/O option (IO_OPTS) is
enabled (True), a value of zero is used for the converted value (PV). This
option is useful to eliminate false readings when the differential
pressure measurement is close to zero, and it may also be useful with
zero-based measurement devices such as flowmeters.
NOTE
Low Cutoff is the only I/O option supported by the AI block. You can set
the I/O option in Manual or Out of Service mode only.

Out of Service: The actual mode is out of service.
The AI Function Block supports three modes of operation as defined by
the MODE_BLK parameter:
• Manual (Man) The block output (OUT) may be set manually
• Automatic (Auto) OUT reflects the analog input measurement
or the simulated value when simulation is enabled.
• Out of Service (O/S) The block is not processed. FIELD_VAL
and PV are not updated and the OUT status is set to Bad: Out of
Service. The BLOCK_ERR parameter shows Out of Service. In
this mode, you can make changes to all configurable parameters.
The target mode of a block may be restricted to one or more of the
supported modes.
Alarm Detection
A block alarm will be generated whenever the BLOCK_ERR has an
error bit set. The types of block error for the AI block are defined above.
Process Alarm detection is based on the OUT value. You can configure
the alarm limits of the following standard alarms:
• High (HI_LIM)
• High high (HI_HI_LIM)
• Low (LO_LIM)
B-5
Rosemount Model 3051 Transmitter with FOUNDATIONTM fieldbus
• Low low (LO_LO_LIM)
In order to avoid alarm chattering when the variable is oscillating
around the alarm limit, an alarm hysteresis in percent of the PV span
can be set using the ALARM_HYS parameter. The priority of each
alarm is set in the following parameters:
• HI_PRI
• HI_HI_PRI
• LO_PRI
• LO_LO_PRI
Alarms are grouped into five levels of priority:
Priority
Number
0
1
2
3-7

Status Handling
Priority Description
The priority of an alarm condition changes to 0 after the condition that caused the
alarm is corrected.
An alarm condition with a priority of 1 is recognized by the system, but is not
reported to the operator.
An alarm condition with a priority of 2 is reported to the operator, but does not
require operator attention (such as diagnostics and system alerts).
Alarm conditions of priority 3 to 7 are advisory alarms of increasing priority.
Alarm conditions of priority 8 to 15 are critical alarms of increasing priority.
Normally, the status of the PV reflects the status of the measurement
value, the operating condition of the I/O card, and any active alarm
condition. In Auto mode, OUT reflects the value and status quality of
the PV. In Man mode, the OUT status constant limit is set to indicate
that the value is a constant and the OUT status is Good.
The Uncertain - EU range violation status is always set, and the PV
status is set high- or low-limited if the sensor limits for conversion are
exceeded.
In the STATUS_OPTS parameter, you can select from the following
options to control the status handling:
BAD if Limited – sets the OUT status quality to Bad when the value
is higher or lower than the sensor limits.
Uncertain if Limited – sets the OUT status quality to Uncertain
when the value is higher or lower than the sensor limits.
Uncertain if in Manual mode – The status of the Output is set to
Uncertain when the mode is set to Manual
NOTES
1. The instrument must be in Manual or Out of Service mode to set the
status option.
2. The AI block only supports the BAD if Limited option. Unsupported
options are not grayed out; they appear on the screen in the same
manner as supported options.
Advanced Features
The AI function block provided with Fisher-Rosemount fieldbus devices
provides added capability through the addition of the following
parameters:
ALARM_TYPE – Allows one or more of the process alarm conditions
detected by the AI function block to be used in setting its OUT_D
parameter.
B-6
Analog Input (AI) Function Block
OUT_D – Discrete output of the AI function block based on the
detection of process alarm condition(s). This parameter may be linked
to other function blocks that require a discrete input based on the
detected alarm condition.
VAR_SCAN – Time period in seconds over which the variability index
(VAR_INDEX) is computed.
VAR_INDEX – Process variability index measured as the integral of
average absolute error between PV and its mean value over the
previous evaluation period. This index is calculated as a percent of OUT
span and is updated at the end of the time period defined by
VAR_SCAN.
Application Information
The configuration of the AI function block and its associated output
channels depends on the specific application. A typical configuration for
the AI block involves the following parameters:
CHANNEL
If the device supports more than one measurement,
verify that the selected channel contains the
appropriate measurement or derived value.
L_TYPE
Select Direct when the measurement is already in the
engineering units that you want for the block output.
Select Indirect when you want to convert the measured
variable into another, for example, pressure into level
or flow into energy.
Select Indirect Square Root when the block I/O
parameter value represents a flow measurement made
using differential pressure, and when square root
extraction is not performed by the transducer.
SCALING
XD_SCALE provides the range and units of the
measurement and OUT_SCALE provides the range
and engineering units of the output.

Setpoint Selection
and Limiting
The setpoint of the PID block is determined by the mode. You can
configure the SP_HI_LIM and SP_LO_LIM parameters to limit the
setpoint. In Cascade or RemoteCascade mode, the setpoint is adjusted
by another function block or by a host computer, and the output is
computed based on the setpoint.
In Automatic mode, the setpoint is entered manually by the operator,
and the output is computed based on the setpoint. In Auto mode, you
can also adjust the setpoint limit and the setpoint rate of change using
the SP_RATE_UP and SP_RATE_DN parameters.
In Manual mode the output is entered manually by the operator, and is
independent of the setpoint. In RemoteOutput mode, the output is
entered by a host computer, and is independent of the setpoint.
Figure C-2 illustrates the method for setpoint selection.

Setpoint Selection.
Filtering
The filtering feature changes the response time of the device to smooth
variations in output readings caused by rapid changes in input. You can
configure the filtering feature with the FILTER_TYPE parameter, and
you can adjust the filter time constant (in seconds) using the
PV_FTIME or SP_FTIME parameters. Set the filter time constant to
zero to disable the filter feature.
Feedforward Calculation
The feedforward value (FF_VAL) is scaled (FF_SCALE) to a common
range for compatibility with the output scale (OUT_SCALE). A gain
value (FF_GAIN) is applied to achieve the total
feedforward contribution.
Tracking
You enable the use of output tracking through the control options. You
can set control options in Manual or Out of Service mode only.
The Track Enable control option must be set to True for the track
function to operate. When the Track in Manual control option is set to
True, tracking can be activated and maintained only when the block is
in Manual mode. When Track in Manual is False, the operator can
override the tracking function when the block is in Manual mode.
Activating the track function causes the block’s actual mode to revert to
Local Override.
The TRK_VAL parameter specifies the value to be converted and
tracked into the output when the track function is operating. The
TRK_SCALE parameter specifies the range of TRK_VAL.
When the TRK_IN_D parameter is True and the Track Enable control
option is True, the TRK_VAL input is converted to the appropriate
value and output in units of OUT_SCALE.
Output Selection
and Limiting
Output selection is determined by the mode and the setpoint. In
Automatic, Cascade, or RemoteCascade mode, the output is computed
by the PID control equation. In Manual and RemoteOutput mode, the
output may be entered manually (see also Figure on page C-5). You can
limit the output by configuring the OUT_HI_LIM and OUT_LO_LIM
parameters.
Bumpless Transfer and
Setpoint Tracking
You can configure the method for tracking the setpoint by configuring
the following control options (CONTROL_OPTS):
SP-PV Track in Man — Permits the SP to track the PV when the
target mode of the block is Man.
C-6
PID Function Block
SP-PV Track in LO or IMan — Permits the SP to track the PV when
the actual mode of the block is Local Override (LO) or Initialization
Manual (IMan).
When one of these options is set, the SP value is set to the PV value
while in the specified mode.
You can select the value that a master controller uses for tracking by
configuring the Use PV for BKCAL_OUT control option. The
BKCAL_OUT value tracks the PV value. BKCAL_IN on a master
controller connected to BKCAL_OUT on the PID block in an open
cascade strategy forces its OUT to match BKCAL_IN, thus tracking the
PV from the slave PID block into its cascade input connection
(CAS_IN). If the Use PV for BKCAL_OUT option is not selected, the
working setpoint (SP_WRK) is used for BKCAL_OUT.
You can set control options in Manual or Out of Service mode only.
When the mode is set to Auto, the SP will remain at the last value (it
will no longer follow the PV.
PID Equation Structures
Configure the STRUCTURE parameter to select the PID equation
structure. You can select one of the following choices:
• PI Action on Error, D Action on PV
• PID Action on Error
• I Action on Error, PD Action on PV
Set RESET to zero to configure the PID block to perform integral only
control regardless of the STRUCTURE parameter selection. When
RESET equals zero, the equation reduces to an integrator equation
with a gain value applied to the error:
GAIN × e ( s )
------------------------------s
Where
GAIN:
e:
s:
Reverse and Direct Action

laplace operator
To configure the block output action, enable the Direct Acting control
option. This option defines the relationship between a change in PV and
the corresponding change in output. With Direct Acting enabled (True),
an increase in PV results in an increase in the output.
You can set control options in Manual or Out of Service mode only.
NOTE
Track Enable, Track in Manual, SP-PV Track in Man, SP-PV Track in LO
or IMan, Use PV for BKCAL_OUT, and Direct Acting are the only
control options supported by the PID function block. Unsupported
options are not grayed out; they appear on the screen in the same
manner as supported options.

The PID function block provides a modified version of feedback reset
limiting that prevents windup when output or input limits are
encountered, and provides the proper behavior in selector applications.

Cascade (Cas)—The SP is calculated in another block and is provided
to the PID block through the CAS_IN connection.
RemoteCascade (RCas)—The SP is provided by a host computer that
writes to the RCAS_IN parameter.
RemoteOutput (Rout)—The OUT IS provided by a host computer that
writes to the ROUT_IN parameter
Local Override (LO)—The track function is active. OUT is set by
TRK_VAL. The BLOCK_ERR parameter shows Local override.
Initialization Manual (IMan)—The output path is not complete (for
example, the cascade-to-slave path might not be open). In IMan mode,
OUT tracks BKCAL_IN.
Out of Service (O/S)—The block is not processed. The OUT status is
set to Bad: Out of Service. The BLOCK_ERR parameter shows
Out of service.
You can configure the Man, Auto, Cas, and O/S modes as permitted
modes for operator entry.
Alarm Detection
C-8
A block alarm will be generated whenever the BLOCK_ERR has an
error bit set. The types of block error for the AI block are defined above.
PID Function Block
Process alarm detection is based on the PV value. You can configure the
alarm limits of the following standard alarms:
• High (HI_LIM)
• High high (HI_HI_LIM)
• Low (LO_LIM)
• Low low (LO_LO_LIM)
Additional process alarm detection is based on the difference between
SP and PV values and can be configured via the following parameters:
• Deviation high (DV_HI_LIM)
• Deviation low (DV_LO_LIM)
In order to avoid alarm chattering when the variable is oscillating
around the alarm limit, an alarm hysteresis in percent of the PV span
can be set using the ALARM_HYS parameter. The priority of each
alarm is set in the following parameters:
• HI_PRI
• HI_HI_PRI
• LO_PRI
• LO_LO_PRI
• DV_HI_PRI
• DV_LO_PRI
Alarms are grouped into five levels of priority:
Priority
Number
0

3-7
8-15
Status Handling
Priority Description
The priority of an alarm condition changes to 0 after the condition that
caused the alarm is corrected.
An alarm condition with a priority of 1 is recognized by the system, but is
not reported to the operator.
An alarm condition with a priority of 2 is reported to the operator, but does
not require operator attention (such as diagnostics and system alerts).
Alarm conditions of priority 3 to 7 are advisory alarms of increasing priority.
Alarm conditions of priority 8 to 15 are critical alarms of increasing priority.
If the input status on the PID block is Bad, the mode of the block
reverts to Manual. In addition, you can select the Target to Manual if
Bad IN status option to direct the target mode to revert to manual. You
can set the status option in Manual or Out of Service mode only.
NOTE
Target to Manual if Bad IN is the only status option supported by the
PID function block. Unsupported options are not grayed out; they
appear on the screen in the same manner as supported options.
Application Information
The PID function block is a powerful, flexible control algorithm that is
designed to work in a variety of control strategies. The PID block is
configured differently for different applications. The following examples
describe the use of the PID block for closed-loop control (basic PID loop),
feedforward control, cascade control with master and slave, and
complex cascade control with override.
C-9
Rosemount Model 3051 Transmitter with FOUNDATIONTM fieldbus
Closed Loop Control
To implement basic closed loop control, compute the error difference
between the process variable (PV) and setpoint (SP) values and
calculate a control output signal using a PID (Proportional Integral
Derivative) function block.
The proportional control function responds immediately and directly to
a change in the PV or SP. The proportional term GAIN applies a change
in the loop output based on the current magnitude of the error
multiplied by a gain value.
The integral control function reduces the process error by moving the
output in the appropriate direction. The integral term RESET applies a
correction based on the magnitude and duration of the error. Set the
RESET parameter to zero for integral-only control. To reduce reset
action, configure the RESET parameter to be a large value.
The derivative term RATE applies a correction based on the anticipated
change in error. Derivative control is typically used in temperature
control where large measurement lags exist.
The MODE parameter is a switch that indicates the target and actual
mode of operation. Mode selection has a large impact on the operation
of the PID block:
• Manual mode allows the operator to set the value of the loop
output signal directly.
• Automatic mode allows the operator to select a setpoint for
automatic correction of error using the GAIN, RESET, and RATE
tuning values.
• Cascade and Remote Cascade modes use a setpoint from
another block in a cascaded configuration.
• Remote Out mode is similar to Manual mode except that the
block output is supplied by an external program rather than by
the operator.
• Initialization Manual is a non-target mode used with cascade
configurations while transitioning from manual operation to
automatic operation.
• Local Override is a non-target mode that instructs the block to
revert to Local Override when the tracking or fail-safe control
options are activated.
• Out of Service mode disables the block for maintenance.
Abrupt changes in the quality of the input signal can result in
unexpected loop behavior. To prevent the output from changing
abruptly and upsetting the process, select the SP-PV Track in Man I/O
option. This option automatically sets the loop to Manual if a Bad input
status is detected. While in manual mode, the operator can manage
control manually until a Good input status is reestablished.

BKCAL_IN of the PID block communicate the status and quality of
information being passed between the blocks. The status indication
shows that communications is functioning and the I/O is working

Application Example:
Feedforward Control
Situation
In the previous example, control problems can arise because of a time
delay caused by thermal inertia between the two flow streams (TT100
and TT101). Variations in the inlet temperature (TT100) take an
excessive amount of time to be sensed in the outlet (TT101). This delay
causes the product to be out of the desired temperature range.
Solution
Feedforward control is added to improve the response time of the basic
PID control. The temperature of the inlet process fluid (TT100) is input
to an AI function block and is connected to the FF_VAL connector on
the PID block. Feedforward control is then enabled (FF_ENABLE), the
feedforward value is scaled (FF_SCALE), and a gain (FF_GAIN) is
determined. Figure C-5 illustrates the process instrumentation
diagram, and Figure C-6 illustrates the correct function block
configuration.

C-12
A slave loop is added to a basic PID control configuration to measure
and control steam flow to the steam heater. Variations in the steam
pressure cause the temperature in the heat exchanger to change. The
temperature variation will later be sensed by TT101. The temperature
controller will modify the valve position to compensate for the steam
pressure change. The process is slow and causes variations in the
product temperature. Figure C-7 illustrates the process
instrumentation diagram.

If the flow is controlled, steam pressure variations will be compensated

output from the master temperature loop is used as the setpoint for the
slave steam flow loop. The BKCAL_IN and BKCAL_OUT connections
on the PID blocks are used to prevent controller windup on the master
loop when the slave loop is in Manual or Automatic mode, or it has
reached an output constraint. Figure C-8 illustrates the correct

You can use the PID function block with other function blocks for
complex control strategies. Figure C-9 illustrates the function block
diagram for cascade control with override.
Application Example:
Cascade Control with Override
When configured for cascade control with override, if one of the PID
function blocks connected to the selector inputs is deselected, that PID
block filters the integral value to the selected value (the value at its
BKCAL_IN). The selected PID block behaves normally and the
deselected controller never winds up. At steady state, the deselected
PID block offsets its OUT value from the selected value by the
proportional term. When the selected block becomes output-limited, it
prevents the integral term from winding further into the limited region.
When the cascade between the slave PID block and the Control Selector
block is open, the open cascade status is passed to the Control Selector
block and through to the PID blocks supplying input to it. The Control
Selector block and the upstream (master) PID blocks have an actual
mode of IMan.
If the instrument connected to the AI block fails, you can place the AI
block in Manual mode and set the output to some nominal value for use
in the Integrator function block. In this case, IN at the slave PID block
is constant and prevents the integral term from increasing
or decreasing.

Operation with Fisher-Rosemount® DeltaV™
CONFIGURE THE
TRANSMITTER
To completely configure the transmitter for use in a Fieldbus segment,
you must perform the following procedures:
1. Create a device profile – A device profile is an electronic
representation of the transmitter that exists only in the DeltaV.
It is like a place-holder for a certain type of transmitter.
2. Define a control strategy – The control strategy is the
relationship between all of the function blocks on the Fieldbus
segment.
3. Commission the device – Commissioning the device involves
copying all applicable parameters from the device profile to the
physical device.
4. Set Transmitter Configuration Parameters – Setting
transmitter configuration parameters configures the device for
use in your specific application.
5. Download the control strategy to the device – Downloading
the control strategy to the device transfers the control strategy
from the DeltaV to the transmitter, where it governs the
relationship and operation of all function blocks.
Create a Device Profile
1. Select DeltaV > Engineering > DeltaV Explorer from the start
menu.
2. Navigate through the file structure to the listing of Fieldbus
ports (see Figure D-2).
