A user can rename or move a point or accumulator in ClearSCADA after HCAL creates the Wonderware Historian tag for it. In this situation, the tag name will not match the ClearSCADA database item's current name.
To find a tag name in ClearSCADA, view the Wonderware Historian Export status attribute in the Status display for the ClearSCADA point or accumulator. For more information, see Wonderware Historian Driver-Specific Status Display Attributes.
