Hi All, Just to discuss our setup, we have 1 redundant CPU and 7 RIOs (2 stations per RIO). We powered off 1 RIO (station 5 & 6) as we have to change a few internal wiring. I expected that nothing will go wrong as the 1xCPU and 7xRIO is in a ring (which is working). What happened based from the diagnostic buffer is that the PLC lost it's link to all 14stations for a brief period then return automatically - which seems connected to rebuilding the ring (please correct me as I'm still trying to find out what causes this) See attached diagnose file.
