Parameter data record

A.1

Parameter assignment and structure of parameter data record

The data record of the module has an identical structure, regardless of whether you
configure the module with PROFIBUS DP or PROFINET IO. With data record 128, you can
reconfigure the module in your user program regardless of your programming. This means
that you can use all the functions of the module even if you configured it via PROFIBUS-
GSD.
Parameter assignment in the user program
The module parameters can be re-assigned in RUN (for example, the input delay 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 in STEP 7 are not changed in the CPU, which means the
parameters set in STEP 7 will be valid again after a restart.
STATUS output parameter
The module ignores errors that occur during the transfer of parameters with the "WRREC"
instruction and continues operation with the previous parameter assignment. The STATUS
output parameter contains a corresponding error code.
The description of the "WRREC" instruction and the error codes is available in the STEP 7
online help.
