5Design and principle of operation

2 Design and principle of operation
The electropneumatic Ex d positioner is mounted on pneumatic control valves and is used toassign the valve position (controlled variable x) to the control signal (set point w). The
positioner compares the electric control signal of a control system to the travel or rotational
angle of the control valve and issues a signal pressure (output variable y) for the pneumatic
actuator.
The positioner consists of an electric travel sensor system (2), an analog i/p converter (6)with a downstream air capacity booster (7) and the electronics with microcontroller (5).
When a set point deviation occurs, the actuator is either vented or filled with air. The signal
pressure supplied to the actuator can be limited by software or on site to 1.4, 2.4 or 3.7 bar.

The fixed flow regulator (9) ensures a constant air flow to the atmosphere, which is used toflush the inside of the positioner housing and to optimize the air capacity booster (7). The i/p
converter (6) is supplied with a constant upstream pressure by the pressure regulator (8) tocompensate for any fluctuations in the supply pressure.

Design and principle of operation

All parts are enclosed in an Ex d housing. The electrical connection is established over a separate terminal compartment also with Ex d protection.
The standard EXPERT valve diagnostics are integrated into the positioner. They provide information on the positioner and generate diagnostic and status messages, which allow faults tobe pinpointed quickly.

2.1 Application typeThe application types 'Control valve' and 'On/off valve' are available. The manual mode
(MAN) and the automatic mode (AUTO) can be selected with both application types.
Depending on the application type selected, the positioner responds differently in automatic
mode (AUTO) .
Control over FOUNDATION™ fieldbus is performed over the AO Function Block (control valve)and over the DO1 Function Block (on/off valve). The application type can be entered in the
Resource Block over the SELECT_DO_1 parameter or at the positioner using Code 49 - h0.
Control valve

On/off valve

AUTO mode

The positioner uses the set point toposition the valve. The valve position(current position) appears in % on thedisplay.

Discrete analysis of the set point The
valve position (current position) in %and O/C (Open/Close) appear inalternating sequence on the display.

MAN mode

The positioner follows the set point given over local operation.

Note− Depending on the application type, certain diagnostic functions cannot be performed oranalyzed (u EB 8389 on EXPERTplus valve diagnostics).
− In manual mode, an on/off valve can be moved past 100 % of the nominal range (with theclosed position for AIR TO OPEN) or below 0 % of the nominal range (with the closed position for AIR TO CLOSE).

KH 8387-5 EN

7Design and principle of operation

2.2 Additional equipment
Binary input
Positioners can be optionally fitted with a binary input.
− Connection to terminals A-B:
The binary input for DC voltage signals allows process information to be exchanged overthe FOUNDATION™ fieldbus network.
− Connection to terminals B-C:
Input to connect a floating contact powered by the positioner. The switching state of thebinary input can be indicated over the FOUNDATION™ fieldbus network.
Note
The binary input is configured in the DI Function Block.
Forced venting
The i/p converter is de-energized when no operating voltage is applied to the corresponding
terminals. The positioner can no longer operate and the control valve moves to the fail-safe
position determined by the actuator, regardless of the set point.

2.3 Configuration using TROVIS-VIEW
The positioner can be configured with SAMSON's TROVIS-VIEW Software.
The positioner has for this purpose a serial interface to allow the RS-232 or USB port of acomputer to be connected to it using an adapter cable.
The TROVIS-VIEW software enables the user to easily configure the positioner as well as viewprocess parameters online.

2.4 Communication
The positioner is controlled completely by digital signal transmission according to FOUNDATION™ fieldbus specification.
Data are transmitted over the bus using digital, bit-synchronous Manchester coding at a
Baud rate of 31.25 kbit/s over twisted-pair wires according to IEC 61158-2.

KH 8387-5 ENFOUNDATION™ fieldbus block model

Note
If complex functions are started in the positioner, which require a long calculation time orlead to a large quantity of data being saved in the volatile memory of the positioner, the alert'busy' is issued over the DD. This alert is not an error message and can be simply confirmed.

3 FOUNDATION™ fieldbus block modelAll the functions and data of the device are assigned to various block types in FOUNDATION™ fieldbus. Each block type covers a different range of tasks. In the SAMSONType 3731-5 Positioner, the following block types are implemented:
Resource Block (RES)The Resource Block (RES) describes characteristics of the fieldbus device, such as the device
name, manufacturer number and serial number. There is only one Resource Block in a device.
Function Blocks (FB)
Function Blocks are responsible for the way a FOUNDATION™ fieldbus device works. A FOUNDATION™ fieldbus application can be configured by linking the input and output parametersof Function Blocks.
The Type 3731-5 Positioner includes the following Function Blocks:− 1x Analog Output Function Blocks (AO FB); execution time: 30 ms− 1x Analog Input Function Blocks (AI FB); execution time: 30 ms− 2x Discrete Output Function Blocks (DO FB); execution time: 30 ms− 2x Discrete Input Function Blocks (DI FB); execution time: 20 ms− 1x Proportional Integral Derivative Function Block (PID); execution time: 40 ms

Instructions u EB 8387-5.

5 Resetting the positioner
The start-up and diagnostic data (in Code 36 Std) can be reset over the XD_COMMAND(41) parameter of the AO Transducer Block.
The device data are reset and the function blocks connected to the values given in the FOUNDATION™ fieldbus specification using the DEFAULTS value in the RESTART (16) parameter ofthe Resource Block (RES).
A warm start of the positioner is performed using the PROCESSOR value in the RESTART (16)parameter of the Resource Block (RES).
The entire diagnostic data as well as the individual messages and histograms are reset overthe RESET_STATUS_MESSAGE_DIAG (147) parameter of the AO Transducer Block.

Status classification and condensed state

6 Status classification and condensed state
All status messages are classified in the positioner to report an error that has occurred. The
status classification can be changed over the DIAG_CLS parameter.
To provide a better overview, the classified messages are summarized in a condensed state(CONDENSED_STATE (81) in the Resource Block). Besides the CONDENSED_STATE parameter, the condensed state can be issued to the discrete output OUT_D of the DI Function Blocks(DI1 + DI2).
Possible condensed states include:
0

Maintenance required

The positioner still performs its control task (with restrictions). A
maintenance demand or above average wear has been determined.
The wear tolerance will soon be exhausted or is reducing at a fasterrate than expected. Maintenance is necessary in the medium term.

2

Maintenancedemanded

The positioner still performs its control task (with restrictions). A
maintenance demand or above average wear has been determined.
The wear tolerance will soon be exhausted or is reducing at a fasterrate than expected. Maintenance is necessary in the short term.

3

Maintenance alarm

The positioner cannot perform its control task due to a functional fault
in the positioner itself or in one of its peripherals or an initialization has
not yet been successfully completed.

7

Function check

Test or calibration procedures are performed in the positioner. The
positioner is temporarily unable to perform its control task as long as
the procedure is taking place.

7 Block model
Several parameters can only be changed in certain modes (see Read/write capability in theparameter description). In this case, not the actual mode is decisive, but the target mode.

7.1 Resource Block (RES)The Resource Block contains all the data that identify the device. It is similar to an electronic
device tag. Resource Block parameters include device type, device name, manufacturer ID,
serial number as well as parameters that affect the behavior of all other blocks of the device.

Block model

See page 25 for parameter list
Note
All time specifications in the Resource Block are specified in the unit of 1/32 ms according to
the FOUNDATION™ fieldbus Specification Version 1.7.
In the Device Description Library supplied by Fieldbus FOUNDATION™ upon which the device
description of Type 3731-5 is also based, these parameters are incorrectly specified as theunit of ms. The specified values supplied by the device are, however, always to be interpreted
as the unit of 1/32 ms.

7.2 Transducer Blocks
Transducer Blocks link the function blocks to the input and output variables of a field device.
For example, the DI Function Blocks are linked to the physical binary input, the forced venting, the current valve position or the condensed state of the positioner. This link to the various
Transducer Blocks is made over the CHANNEL parameter of the individual function blocks.
The table below shows how CHANNEL is assigned to the function block:

7.3 Advanced Positioner Transducer Block (AO TRD)
The Advanced Positioner Transducer Block (AO TRD) contains an output value from an upstream Analog Output Function Block. This value is used to position a control valve. The blockcontains parameters to adapt the positioner to the actuator and valve as well as for valve
start-up and diagnostics.
Action on fault detection
The action on fault detection for the "Maintenance alarm" state in the condensed state can be
configured in the XD_FSTATE_OPT parameter as follows:− Hold last value− Move to fail-safe position− Move to fault state value XD_FSTATE_VAL
The action on fault detection to transfer to the O/S mode can be configured in the XD_OOS_
OPT parameter as follows:− Hold last value− Move to fail-safe position− Move to fault state value XD_FSTATE_VAL
The AO Transducer Block (AO TRD) can still set an output error in the AO Function Block. For
this purpose, the following events to activate an output error can be configured in the
ALARM_OPTION parameter.
− No (never)− Local Override (when the AO TRD is in the LOCAL OVERRIDE mode, i.e. the positioner is
set locally in the SAFE mode or the forced venting is activated)− MAN (when the AO TRD is in MAN mode)− Block alarm (when the AO TRD has a MAINTENANCE NOW block error)− AO TRD fault state (when the action on fault detection is active)− AO O/S set fault state (when the AO Function Block in the O/S mode, the valve is
moved to the FSTATE_VAL of the AO Function Block)14

Proportional Integral Derivative Function Block (PID)

A PID Function Block contains the input channel processing, the proportional-integral-derivative (PID) control loop and the analog output channel processing.
The configuration of the PID Block (PID controller) depends on the automation task. Simple
control loops, control loops with output value feedforwarding, cascade control and cascade
controls with limitation in combination with another controller function block can be implemented.
The following options are available for data processing within the PID Function Block (PID
controller): signal scaling and limiting, mode control, feedforward control, override tracking,alarm limit detection and signal status propagation.

18

KH 8387-5 EN

Block model

The PID Block (PID controller) can be used for various automation strategies. The block has aflexible control algorithm that can be configured to match the application.
The PID Function Block receives its set point depending on the mode (MODE_BLK) from the
input variables CAS_IN, RCAS_IN or SP. An internal working set point is generated basedon PV_SCALE, SP_HI_LIM, SP_LO_LIM, SP_RATE_UP and SP_RATE_DN.
The block receives the process value over the IN input variable which is used to generate theprocess variable PV, taking into account the PV_SCALE and the filter of the first order PV_
FTIME.
These values are fed to the internal PID algorithm. This algorithm consists of a proportional,
an integral and a derivative component. The output value is calculated from the set point SP
and the process variable PV resulting from the set point deviation.
The single PID components are included in the calculation of the output variable as follows:− Proportional component:
The proportional component reacts immediately and directly when the set point SP or theprocess variable PV changes. The output variable is changed by the proportional factor
GAIN. This change corresponds to the set point deviation multiplied by the gain factor. If
a controller works only with a proportional component, the control loop has a steadystate error signal.
− Integral component:
The set point deviation resulting from the calculation of the output variable using the proportional component is integrated over the integral component of the controller until it isnegligible. The integral function corrects the output variable depending on the size andduration of the system deviation. If the value for the integration time RESET is set to zero,
the controller works as a P or PD controller. The influence of the integral component on
the control loop increases when the value of the integration time RESET is reduced.

KH 8387-5 EN

19

Block model− Derivative component:
In controlled systems with long delay times, e.g. in temperature control loops, it is better
to use the derivative component RATE of the controller. Using the derivative component
RATE, the output variable is calculated depending on the rate of change of the set point
deviation.
An OUT value is generated from the calculated output value based on the OUT_SCALE,
OUT_HI_LIM and OUT_LO_LIM parameters. It can be forwarded to a downstream function
block.
The status of the OUT value can be influenced by the STATUS_OPTS parameter dependingon the status of the input variables of the PID Function Block. As a result, the fault state of afollowing output block can be activated, for example.
The BYPASS parameter allows the internal set point to pass directly through to the out value.
The FF_VAL input value allows feedforward control, while TRK_IN_D and TRK_VAL allow thedirect tracking of the out value.

Discrete Input Function Block (DI1 FB + DI2 FB)

The DI Function Block processes single discrete signals and provides them to other function
blocks over the OUT_D parameter. The positioner has two DI Function Blocks which provide
the options listed in following. The application type is set over the SELECT_DI_1…2 parameters of the Resource Block.
− 5 – 30 VDC (DI1)
As a standard feature, the positioner comes with a contact input to analyze binary voltage signals (terminals 87 and 88). The DI1 Function Block analyzes the state of the contact and issues it over OUT_D.
− Floating contact (DI2)
The positioner can be fitted with an optional binary input to analyze a floating contact(terminals 85 and 86). The DI2 Function Block analyzes the state of the contact and issues
it over OUT_D.
− Int. solenoid valve (DI1, DI2)In this setting, the current switching state of the optional forced venting is analyzed andissued over OUT_D. '0' indicates an inactive forced venting and '1' an active forced venting.

Other parameters

The Stale Counter serves to judge the "quality" of a process variable received over a configured cyclic connection (publisher/subscriber connection).
These connections are used to transfer the process variable linked amongst the various function blocks. For this purpose, the upstream block (publisher) sends the process variable overthe bus at scheduled times. The downstream block(s) (subscriber) responds at the scheduled
times. The blocks that are to receive data monitor whether a valid value exists at the scheduled time. A value is valid if it exists with the status "Good" at the scheduled time.
The Stale Counter defines how many "Bad" (stale) values can be accepted in sequence before the Fault State of the block is activated.
This monitoring function is deactivated by setting the Stale Counter to zero.

8.1 Link Objects
Link Objects are used to link the inputs and outputs of the function blocks (configurable cyclicconnections).
A maximum of 22 Link Objects can be configured for each positioner.

8.2 LAS Functionality
The number of links and schedules that can be used is matched to the requirements of standard process control systems available on the market.
The positioner functioning as an LAS can support the following:− 2 schedules− 2 subschedules− 5 sequences per subschedule− 48 elements per sequence
In the delivered state, the device is configured as a basic device.
