I have a micrologix 1400 that will fault out on error code 71h every once in a while, I am talking months in between fault.
Now, sometimes I can clear the fault and the processor will come right back up working, no problem, and now other times, it will come back up but no I/O modules working. I shut it down again, wait a little while, start it back up, and low and behold everything works again.
it is frustrating that it is so intermittent. Is there a way I can detect or catch what is causing the issue because it happens so infrequently?
