Parameter assignment and structure of parameter data set
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.
The following figures describe the structure of data record 128 as of firmware version V1.0.
Configuration in the user program
You can configure the modules in runtime.
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 are not changed in the CPU by this action.
This means the parameters set in STEP 7 are still valid after a restart.
Output parameter STATUS
If errors occur when transmitting 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.
Error message
The module always checks all the values of the transferred data record. Only if all the values
were transferred without errors does the module apply the values from the data record.
The instruction WRREC for writing data records returns corresponding error codes when
errors occur in the parameter STATUS.
The following table shows the module-specific error codes and their meaning for the
parameter data record 128:
