Currently, I am using SFC13 to get the diagnostic data for each drop from the CPU. So far I've only seen useful data in the first six (6) bytes. If I monitor Station Status 1, bit 0 I can see a fault if I unplug the Profibus connector. But I also want to know if a module failed within the ET200S rack. I don't want to monitor down to point level (bytes 15-34) if I don't have to, but I would like to recoginze a general module fault.
I have also tried to use data generated in OB82 and OB86, but I can't get the station ID, only reference to the data area in the CPU.
Has anyone done this or something similar?
