There is a PM864A thats shut down suddenly (like in the photo attached). I cant find anything in the redundant cpu log because it erases when the error occurs. Can somebody help me?

Thanks,

Joao Paulo.

Hello,

The picture of CPU shows no any LED lighting - may be there some problem in power supply. Please check +24VDC line and also external battery connection.

Is the CPU starts after restart, is the redundant CPU switch0over and take control after the fault?

Hello,

I already checked the power supply and it doesnt have any problems. The CPU starts normaly after a restart. The redundatn CPU take control after the fault. I already replaced the CPU and the problem persists.

Best regards.

If the CPU is OK, you can have many different issues it to go to fault status - here are some typical:
-both Ethernet connections to the CPU are disconnected
-the CPU loses connection to the I/O modules

From your pictures I can see there are not I/O, connected by FO to the CPU (direct) - may be you are using Profibus. Also I can see almost all CP's are connected to the first CPU - most probably Profibus is there. Please send a scatch of your system configuration

May be you need to have one CP854 to the first CPU and the second CP to the second CPU? I can see that you don't have BC810

Check the controller is getting 24VDC. If it is then the fuse in the controller base plate is gone...
