Rename a Tag | Historian 2022 Documentation

Before you begin

To rename a tag, you must be a member of the administrator's group with tag-level security.

When you rename a tag, you can choose between the following options:

Rename using an alias: In this case, the old name is called the tag alias. You can retrieve tag data using the tag alias as well. When you copy a tag, the tag alias is captured as well to aid in an audit trail.
Note: If a tag name contains a comma or a semicolon, you cannot view the tag alias.
