This communication is configured by the GSD modules. GSD module is a set of data, which the ND800PA and DCS/PLC exchanges cyclically until the end of the world. The GSD modules are listed in the GSD file. The ND800PA GSD file name is Nel_052d.gsd. During the DCS/PLC configuration, the configuration software, such as Siemens Simatic Step 7, reads the Nel_052d.gsd file and asks user, which GSD module should be used. The ND800PA has following GSD modules; • SP • SP,READBACK, • SP,CHECKBACK • SP,READBACK, CHECKBACK • RCAS_IN,RCAS_OUT • RCAS_IN,RCAS_OUT.CHECKBACK • SP,RB,RC_I,RC_O, CB Abbreviations; RB=READBACK, RC_I=RCAS_IN, RC_O=RCAS_OUT, CB=CHECKBACK For compatibility reasons the modules are represented in both Identifier Byte format and in Extended Identifier Format. SP is the valve position setpoint in the AUTO mode. The ND800PA Analog Output Block default target mode is AUTO. The range is 0-100%. READBACK is the valve position measurement. The range is 0-100%. contains the limit switch information. The values are: 1 = closed 2 = opened 3 = intermediate If the limit switches are not installed, the value is determined from the position measurement sensor as follows: 1 = closed, Position <= 2% 2 = opened, Position >=98% 3 = intermediate, 2 < Position < 98 RCAS_IN is the valve position setpoint in the Remote Cascade mode. Before this setpoint is used, the Analog Output Block (AO) actual mode has to be the RCAS mode. This requires as follows; • AO block target mode must be RCAS. • The DCS/PLC has to go through the remote cascade initialization sequence with the ND800PA. This is done by using the STATUS bytes of the RCAS_IN and RCAS_OUT signals. RCAS_OUT feeds back the SP or RCAS_IN, depending on the mode. CHECKBACK is a diagnostic signal. All control systems has their ways to convert this standard bit-information to human readable alert messages. See table 1. 11(52) EFTA01216880 ND800PA GSD modules Table 1. CHECKBACK signal bit-enumeration. Byte Bit Description Indication Class 0 0 Field device in Fail safe active R 1 Request for local Operation R 2 Field device under local control.

A Indication. will be automatically reset after 10s. In addition to the actual value (IEEE-754 float), all GSD module signals (except CHECKBACK) have a status information (See table 2). The status tells the quality of the value. Example; READBACK status is bad, device failure, if the position measurement sensor is broken. Table 2. Status byte mapping.

These signals are not included in the GSD modules. DIAGNOSIS contains standard diagnostic information (See table 3). This parameter is available to DCS/PLC if it supports a DP service called ddlm_slave_diag. The idea here is that this parameter is not polled cyclically, but whenever new information is available, the ND800PA rises a diagnostic flag (in cyclic communication). When DCS/PLC sees that flag, it reads the DIAGNOSIS parameter by using the ddlm_slave_diag service. DIAGNOSIS EXTENSION is manufacturer specific extension to the DIAGNOSIS (See table 4). This parameter is included in the ddlm_slave_diag service only if the PROFIBUS Ident Number is selected to be Manufacturer specific. Table 3. Dia nosis Darameter bit-enumeration.

Position Sensor Rotation Defines relationship between the position sensor rotation and the valve action. If the position sensor rotates clockwise when the valve closes, set Standard: clockwise to close. With inverse rotation set Nonstandard: counter-clockwise to close. See /1/ for more information of operation directions and air connections. Options are • Standard : Clockwise to close • Non-standard : Counter clockwise to close Actuator type Actuator type selection. Options are • Undefined • Single acting actuator • Double acting actuator Valve Type Valve type selection. Options are • Linear moving valve, sliding valve • Rotary moving valve, part-turn Positioner Fail Action Configuration of the action taken during the LOSS OF SUPPLY POWER (supply pressure is available). This action takes place ALSO when the positioner software notices a fatal device failure. In these both cases the spool valve feeds C1 (pneumatic connector) and releases C2 pressure. See /1/ how to set this parameter. Options are • Close • Open Actuator Fail Action Actuator fail safe position during LOSS OF SUPPLY PRESSURE. This parameter is informational only. • Not initialised • Opening (100%) • Closing (0%) • None (Double acting actuator) Dead Angle Compensation This adjustment is used to change the valve travel from fully closed to a desired travel with a small change in input signal near the 0% value of the input signal range. This can be used to compensate dead angle in a ball or segment valve such that it is equal to the ao adjustment in conventional Neles positioners. The ac, adjustment is used especially with small ball valves which require a turn of several degrees from the closed position before any flow through the valve is perceptible. Suitable ac, values for Neles segment and ball valves can be found in /1/. See figure 13. Limit switches This parameter defines either the limit switches are installed or not. Options are; • Not installed (default) • Installed 5.2.2 Profibus Communication Fail Safe Action Fail Safe Mode Defines reaction of device if communication fault is still detected after fail safe time.

Fail Safe Default Value Default Value for the setpoint input if communication fault is detected. 5.2.3 Servo Controller Servo controller gain The servo controller gain value. This parameter is adjusted automatically during the Automatic Travel Calibration. After travel calibration the value is 1.0. For enhanced control use value 1.2. Servo controller parameter D Servo controller tuning parameter D. • 0.0 for double acting actuators (factory set) • 1.0 for single acting actuators (factory set) Servo controller parameter B Servo controller tuning parameter B. This parameter is adjusted automatically during the Automatic Travel Calibration. After travel calibration the value is 1.0. 5.2.4 Valve Diagnostics These settings are used to set limits for different diagnostics information to warn the user when the limits are exceeded. The limits should first be set to high values such that no unnecessary warnings are given. After gaining experience, the user can tune the limits to more accurate levels. When a particular limit is exceeded, it is reported in corresponding Diagnosis and Diagnosis extension status messages. Supply Pressure Set this parameter to the average value of the positioner supply pressure. Supply pressure is used to calculate the load factor. Travel Deviation Warning Limit Warning limit for the deviation between the setpoint and actual travel. Travel Deviation Alarm Limit Travel deviation alarm limit. Load Factor Warning Limit Load factor warning limit. In the case of a single acting actuator, the load factor shows the actuator load with respect to the present spring force, i.e., a load factor of 100% indicates that the actual load may exceed the spring force. For double acting actuators, the load factor shows the actuator load with respect to the user-given supply pressure level, i.e., a load factor of 100% indicates that the actual load may exceed maximum attainable pressure difference being equal to the supply pressure. A high load factor indicates the presence of high friction or an undersized actuator if the given supply pressure is equal to actual supply pressure level. Load Factor Alarm Limit Load factor alarm limit. Valve Full Strokes Warning Limit Warning limit for the distance the valve has traveled in full strokes. One full stroke means 18(52) EFTA01216887 Operation valve movement from 0 to 100%. E.g. if valve moves from 40% to 50% full strokes increases by 0.1. Valve Reversals Warning Limit Warning limit for the number of changes in valve movement direction. Actuator Full Strokes Warning Limit Warning limit for the distance the actuator has traveled in full strokes. Actuator Reversals Warning Limit Warning limit for the number of changes in actuator movement direction. 5.3 Input Group The input signal modifications accomplished using Dead Angle Compensation, Cut-Off and Limit functions are presented in figure 13. 100% OUTPUT Dead Angle Compensation INPUT 100% 14- Setpoint Cut-Off CLOSE Setpoint Cut-Off OPEN Lower Limit Valve Position Upper Limit Valve Position Figure 13.
