I wonder if there is a way to accomplish the following tasks using EF attribute templates:
- access the timestamp of a calculated maximum value (PI Point Data Reference, maximum), maybe assign it to an EF attribute
- use the timestamp of a calculated value (max) to find the value for another EF attribute (PI Point Data Reference)
I found a similar question in PI Square from 2013 mentioning custom AF data references - but no real solution.
After 3 years gone - is there a generic solution for this now?
