PROFIBUS-DP
8 CONFIGURATION IN THE PROFIBUS-DP MASTER
User parameters (hexparameters) are not required.
8.1 Configuration of the Process Values
Firstly the PDI (Process Data Input) is input (from the positioner to the controller).
PDI: Process Data Input (from the positioner to the controller)
Name Description Identifier
PDI:POS
Actual position (position)
Actual value of position controller as ‰. Value range 0 – 1000.
Values < 0 or > 1000 are possible if e.g. Autotune has not run through
correctly.
GSD file: PDI:POS
Identifier (HEX): 41, 40, 00
PDI:CMD
Nominal position (command)
Set-point value of position controller as ‰. Value range 0 – 1000.
GSD file: PDI:CMD
Identifier (HEX): 41, 40, 01
PDI:PV
PDI:SP
Process actual value (process value)
Actual value of process controller in physical unit (as set in the menu
P.CO INP or P.CO SCAL), max. value range -999 – 9999, depending on
internal scaling
Process set-point value (setpoint)
Set-point value of process controller in physical unit (as set in the menu
P.CO INP or P.CO SCAL), max. value range -999 – 9999, depending on
internal scaling
GSD file: PDI:PV
Identifier (HEX): 41, 40, 02
GSD file: PDI:SP
Identifier (HEX): 41, 40, 03
PDI:TEMP
Device temperature (temperature)
Temperature of 0.1 °C is measured on the CPU board by the sensor,
Value range -550 (-55 °C) – +1250 (+125 °C)
GSD file: PDI:TEMP
Identifier (HEX): 41, 40, 04
PDI:MODE
Operating mode (operation mode)
Operating mode:
0: AUTO 10: P.TUNE
1: MANUAL 12: BUSSAFEPOS
2: XTUNE
9: P.QLIN
GSD file: PDI:MODE
Identifier (HEX): 41, 00, 05
PDI:ERR
Error
Indicates the number of the process value (output) which was not written.
The value is retained until it is deleted with PDO:ERR.
HEX
14 PDO:CMD / SP
16 PDO:MODE
GSD file: PDI:ERR
Identifier (HEX): 41, 00, 06
PDI:
PCONact
0: Position controller (8692)
1: Process controller (8693)
GSD file: PDI:PCONact
Identifier (HEX): 41, 00, 0A
PDI:PV and PDI:SP can be selected for Type 8693 (process controller) only and are beneficial only when process
controller activated.
PDI:PCONact can be selected for Type 8693 (process controller) only.
