GE Fanuc CPU Failure
CPU Failure on GE Fanuc Series 90-70 PLC

I have a GE Fanuc Series 90-70 PLCs providing F&G coverage for a section of my plant. The CPU failure error comes up intermittently and sets-off a 7.5 Hr timer that trips the plant after timeout.

Does anyone have this experience or could point me to possible causes of this error?

I have very bad experience with this CPU. during any power jerk a internal IC burnt. After replacing more then three CPU. Then I change hardware with Siemens. Now I am happy.
