Parameter data records

B.1

Parameter assignment and structure of the parameter data records

The data records of the module have an identical structure, regardless of whether you
configure the module with PROFIBUS DP or PROFINET IO.
Dependencies for configuration with GSD file
When a GSD file is used to configure a module, dependencies can arise when "assigning the
parameters".
There are no dependencies for this module. You can assign the individual parameters in any
combination.
Parameter assignment in the user program
You have the option of reassigning the module parameters in RUN (e.g., the reaction of the
individual channels to CPU STOP can be changed in RUN without affecting the other
channels)
Parameter assignment in RUN
The WRREC instruction is used to transfer the parameters to the module using data records
64 to 95. The parameters set in STEP 7 do not change in the CPU, which means the
parameters set in STEP 7 are still valid after a restart.
The parameters are only checked for plausibility by the module after the transfer.
Output parameter STATUS
The module ignores errors that occurred during the transfer of parameters with the WRREC
instruction and continues operation with the previous parameter assignment. However, a
corresponding error code is written to the STATUS output parameter.
The description of the WRREC instruction and the error codes is available in the STEP 7
online help.
