Parameter assignment and structure of parameter data record

The data records of the module have an identical structure, regardless of whether you
configure the module with PROFIBUS DP or PROFINET IO.
Parameter assignment in the user program
The module parameter settings can be changed in RUN (for example, the voltage or current
values of selected channels can be edited in RUN without having an effect on the other
channels).
Changing parameters in RUN
The "WRREC" instruction is used to transfer the parameters to the module using data record
128. The parameters set with STEP 7 will not be changed on the CPU, which means that the
parameters set in STEP 7 will be valid again after a restart.
Output parameter STATUS
If errors occur when transferring parameters with the "WRREC" instruction, the module
continues operation with the previous parameter assignment. The STATUS output
parameter contains a corresponding error code.
You will find a description of the "WRREC" instruction and the error codes in the STEP 7
online help.
