AC500 PLC goes to stop
I have one AC500 PLC with problemsCPU ABB: PM581-ETH C1, 256 Kb, Ethernet, 24 V DC, 2xSerial,FBP, Display, SD Slot
Control Builder : 188.8.131.52 Build 25 feb 2008
Serial: 0278 1S120 05 00000675
Error: E2 037
The cpu Is working normal, but without intervention it goes to stop.
We restart and it works again, but it has failed 3 or 4 more times in the same way.
Could you please recommend us what to check?
what could be the cause?
IMHO you have to check how you set the cycle time in your CPU because the error E2 - 037 identifies, according to the manual: - Cycle time is greater than the set watchdog time
The recommended solution is to perform a change task configuration, and verify how is set the watchdog time.
Hope this help you
