Servicing PLC with 5/04 processor. It was displaying BATT error and program was gone. I replaced battery, reloaded program put it in Run mode.
Everything was fine until power got interrupted. After restoring power Fault alarm has been displayed and program gone. Connected to processor and reloaded program back. Everything got back on track, no alarms or faults.
Processor was in run mode and communication was fine in both channels (RH+ and serial). To test what happened I intentionally turned power off.
Same thing happened. Fault alarm and program gone. I’ve connected to processor over RS232 and check errors status. In error description window it says “Unexpected hardware watchdog timeout or an ASIC reset occurred.”
Battery Low S:5/11 is set at “0”.
“Clear Major Error” reseted all and I was able to dawnload program again but if I take power off it will do the same.
So I don’t know if it’s problem with ASIC (I am not familiar with this) or processor is bad.
I tried two new batteries so that isn’t problem.
Will appreciate your support and suggestions.
