Rename tags

The Historian Tag Rename Utility lets you rename tags in AVEVA Historian while preserving the historical data associated with those tags. At rename, the old tag’s data history is linked to the new tag name that you specify.

Note: For classic history blocks, use the earlier version of the Tag Rename utility. In this case, be sure to run the earlier version before you run the new Historian Tag Rename Utility.

Historian tags, along with other tags, are stored in the Runtime database in the Tag, AnalogTag, DiscreteTag, and StringTag tables. You can view these tags in the Operations Control Management Console. These tags cannot be renamed from the Historian Configuration Editor.

To view Historian tags in the Runtime database

• In the Operations Control Management Console, expand Historian, expand Historian Group, expand Configuration Editor, expand System Configuration, and then expand Tag Configuration.

The Historian also stores tag meta data, including information about tag name and tag version, in history blocks.
