Hi All,
Was called to a Siemens S7 PLC today in stop mode.
Both Profibus & Ethernet module showing BF.
Run to Stop to Start didn't restart the CPU.
I took a CPU diagnostics dump.
Powered off and back on all came up running fine.
Looking at the diagnostics you run by incomming event time rather than event.
Events run 1-100
Time from 07:46 - 09:13
I have added some comments in Red and think it might be caused by the CP343-1 card but am open to suggestions from the more experienced.
Many Thanks in advance.
