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
You have the option to re-configure the module in RUN (e.g. the response of selected
channels to the CPU-STOP state can be changed 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.
The module ignores errors that occur 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.
