When input PI Tags are referenced in PI Vision 2020+ calculations, they do not automatically detect PI Tag name changes. For users with a lot of calculations, this can be extremely problematic in the event of a PI Tag name change. In the event of a name change, the following error is produced: [-12301] Performance Equation parsing error. Possibly updating the PE scheduler to reference the PointID instead would be beneficial.
It seems like a small leap for tags on a vision display to update to tags in a calculation.
