Further information
The structure of parameter sets (data records 0, 1 and 128) is described in the system data
section of the appendix. You must be familiar with this structure if you want to modify module
parameters in the STEP 7 user program.
The structure of diagnostic data (data records 0 and 1) is described in the system data
section of the appendix. You must be familiar with this structure if you want to analyze
diagnostics data of the modules in the STEP 7 user program.
