AB PLC CPU Malfunction

Hi!

i have experienced a very strange thing.
When AB PLC CPU went into fault status, all digital ouputs became ON status.

is there anyone experienced similar phenomenon?

exact model is AB PLC5 L40E(1785 L40E)

reply please..

Check settings for your outputs. Probably some of them have a flag: goes to "1" if CPU faulted.

What is the error?

Check for a fault routine. Status S:29
