Rename (Alias) Tags

About this task

You can rename tags through the Non-Web Historian Administrator, Excel Add-in, ihuAPI, and SDK. New tag names are called active tags and old tag names are called as aliases. Tag renaming will only update or modify tag names without modifying or changing the tag properties.

If you want to modify a renamed tag property, be aware that of all the alias' tag properties will also be updated. Whenever you rename a tag name, then the active tag name (that is, the new tag name) will be visible in the Tags list on Historian Administrator Tag Maintenance page. You can rename tags multiple times, but only the latest active tag name will be visible in the Tags list.

Procedure

Export Tags that you want to rename from the Historian Server. For more information, refer to the Exporting Tags.

Important: You must only include Tagname in the list of fields to export.
Insert a column to the right of the Tagname column.
Double-click the column heading, and then type “New Tagname”.
Select a cell in the New Tagname column, and then type a new tag name.

Important: You must specify a tag name in all the rows of the New Tagname column. Currently, If you do not want to rename any of those exported tags, then you must delete that row and rename the remaining tags.
From the Historian Menu, select Administration and then select Rename Tags.
The Historian Rename Tags window appears.
Select Yes. If successful, a window appears confirming completion of the rename function.
