AlThePal (Customer) asked a question.
It's possible to view CPU error events remotely. You can also send a critical or non-critical error flag so this can be viewed in a SCADA system.
However, I can't find out a way of clearing the error history in code, so that once a user has seen an error they can clear it without having to connect to the PLC with Productivity Suite. Is this possible?
1.) It's possible to view CPU error events remotely?
Answer: Yes. You can use the web server or mobile function to view those tags remotely. See help topic P261 and/or P248.
2.) There are no system tags related to clearing error history. Below is list of system tags pertaining to critical and non-critical error logs:
>2) There are no system tags related to clearing error history.
Refresh Critical Error Log and Refresh Non-Critical Error Log seem work for their respective lists in 3.12.1.21.
@kewakl (Customer) You are correct. Just tested and each tag clears it's respective log.
No worries, I just discovered this feature today as I was looking at the image you posted -- as it has those tags listed.
I was attempting to do some unorthodox coding as described here.
Maybe we could have a blurb in the respective tag's description that indicates this 'clearing' feature.
+1 agreed. I will request to the Productivity team to get this updated to make it clearer.
