Please help

[gregoryg]

Make a change in DX0 (for test purposes), set system stop if ADF occurs and try to analyze I stack and B stack. To keep CPU running you can use OB25.
ADF sometimes happens if during cold restart of CPU one of the modules did not respond correcly or ... maybe there is an error in changed blocks? (Nobody is perfect).

I Have download the OB25 CPU is running but ADF is blinking.I will try to change the DX0 as you suggest.
Thanks for great help

In your original DX0 stop caused by ADF is disabled. If you eneble it you will require OB25 to keep CPU running. Till now it's not needed.

[gregoryg]

FB174 accesses input words from IW0 to IW10 (bytes 0-11). Check existence of all input modules inside this range. (I Stack shows error during access to IW4).
