PM 583 Ac 500 PLC changed to stop model suddenly from run mode during operation
Hi,
The PLC shown in the picture is connected with High Availability (redundancy).
During normal operation, it is suddenly shifting to Stop mode.
What are the reasons or causes triggering this scenario?

Hi
to obtain the error code you need to test with DIAG button the response of the CPU, or if you have the Automation Builder Tool and the source of SW try the Online diagnostics, to see the error registry.
Only when you know the error code can you make other assumptions. This is probably, as often happens, a false contact at the transmission bus level on the I / O peripherals. Especially because you said that the fault is random.
In the manual of the Automation Builder Suite you can find some instruction to test the error code of CPU
Hope this help you
