Parameter assignment and structure of parameter data record

Parameter assignment in the user program
You can change the parameters of the module in RUN.
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 are valid again after a restart.
STATUS output parameter
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.
