System Fault SF

This is a SF that I am getting on my processor. I'm not sure how to correct this fault. This processor is still working with no issues, but I can see the SF LED red light on.

Thanks

If a module with diagnostic capability for which you have enabled the diagnostic interrupt detects a change in its diagnostic status, it sends a diagnostic interrupt request to the CPU:

·There is a problem or a component requires maintenance or both (event entering state).

·There is no problem and no further components require maintenance (event exiting state).

The operating system then calls OB82.

The local variables of OB82 contain the logical base address as well as four bytes of diagnostic data of the defective module (see the following table).

If OB82 has not been programmed, the CPU changes to the STOP mode.

You can disable or delay and re-enable the diagnostic interrupt OB using SFCs 39 to 42.
