Is it possible to change an Attribute's name, without breaking the links to its associated Vision displays?
I just tested this, and PI Vision display element did not pick up the name change automatically. The simple trend I utilized showed the data before the name change, and then displayed 'No Data' after the name change.
Depending on how important this is to your operation you could build a ProcessBook display and load that in your displays folder on your PI Vision server. ProcessBook easily picks up attribute name changes, and then when automatically converted for display in PI Vision the newly re-named attribute values show up without an issue.
We ended up using two SQL queries provided by OsiSoft's tech support. The queries modify the VISION-DB so it acknowledges:
1. AF Attribute's name change
2. AF Attribute's path change
If you ask for it, OsiSoft will do a Bomgar session and help you with that.
