A user can rename or move a point or accumulator in Geo SCADA Expert after HCAL creates the Wonderware Historian tag for it. In this situation, the tag name will not match the Geo SCADA Expert database item's current name unless you use the RenameTag method to realign the two names.
If the two names differ from each other, you can find the Geo SCADA Expert source point for a Wonderware Historian tag.
This is how. Tags have a description associated with them. Geo SCADA Expert sets this to the class name and object ID of the point or accumulator. This is so that you can match tags in Wonderware Historian with items in the Geo SCADA Expert database. You can read the tag description in Wonderware Historian (see the Wonderware Historian documentation). You can then search for the Object ID in the Geo SCADA Expert database (see Working with the Database Schema).
