I am trying to configure an AfAttribute which can give me the latest Event Time of a PI Tag i.e. instead of 'Value' I want 'Event Time' of the tag, not sure how to do it. Any help please.
As an option to display a time stamp can use the following option:
As far as i know, you can't use the PI Point DR to return the timestamp of a PI Point Event.
However, you can use e.g. Performance Equations or Abacus / Analytics to get the timestamp and store that in a separate PI Point & AF attribute. Look here for the function reference: https://livelibrary.osisoft.com/LiveLibrary/content/en/PIServer2014R2-v1/GUID-C5878E9B-2F10-4D58-ABAC-C62C2C271FC1
It's also on my whishlist to have a derative of the PI Point DR to do statistics on the time or quality of a PI Point (e.g. % good of last day, count of events of last day, etc.)
Hope this helps!
We can also create another PE Tag to archive the snapshot timestamps with this formula. Use natural triggering.
Then just use this PE Tag with the PIPoint DR.
