Festo CPX Profibus Diagnostic Channel


We have discussed the use of Diagnostic Channels in this thread:


Siemens ET200S works fine as per KBA AUS1-131-000601153757. 

Does anyone have experience with Festo CPX-4AE-U-I? Which channel to configure?

  • So we found that it does work to some extent, but it has an issue: only the first faulty channel is reported. So if we have 4 AI channels and the first and second are both faulty, only the first is reported as faulty. This is also documented in the manual.
