We are using PI system explorer 2017 R2.
We have gas well in which one attribute show 198 in txt file format symbol.
Please find pic. My question is what is it?
I believe that is an Annotation on that PI Point.
You can also annotate Elements, Event Frames and other things.
See Annotations in PI AF.
Andrew is correct. It indicates your PI point has an annotation. The value of the annotation appears to be a 192. You can use the PI System Management tool with the Archive Editor plug in (under Data in the tree) to get the current value and view the annotation.
