Hello dear colleagues, We have been reported by one of our clients that a PLC on their system has switched to STOP mode and could only be set to RUN mode manually by switching the power OFF and ON. We acquired the diagnostics history and noticed a strange series of events. I wanted to ask your opinions before we take any actions. First I want to give you a brief explanation of the system to answer some of the questions you might have when you take a look at the diagnostics file:
Now I will summarize the chain of events that is important to us, in chronological order, from the diagnostics poinf of view:
We suspected that maybe the client changed the selection of configuration during runtime and did not want to tell us they did that but it does not also make sense, because even if they change the configuration a "Startup OB" is required for the new configuration to be applied, but there is no sign of a startup of PLC before those errors occured.
