I have had a customer PLC loose the date twice now on the same PLC. I ask if there have been any power outages and they say no.
Every time I go in to check the date/time it shows ??
If I look at wallclock year it shows 1969.
it has happened 4 months apart. month and day went to 4/22.
The PLC does not stop in operation but some numbers I am recording using hour/day/month get screwed up.
Anyone else see this behavior?
