Rename a Tag

Before you begin

• You must be a member of the administrator's group with tag level security.
• If you want to rename a tag permanently, to avoid loss of data, stop the collector instance.

About this task

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.
• Rename permanently: In this case, the old name is no longer captured. Therefore, you can create another tag with this old name. You cannot store and forward data using the old name. This implies that data for the tag is collected separately for the new name.

Procedure

1. Access Historian Administrator.
2. Select Tags.
3. Select the tag that you want to rename.
4. Select Copy/Rename Tag .
   The Copy/RenameTag window appears.
5. If you want to rename the tag using an alias, select Rename (Alias). If you want to rename the tag permanently, select Permanent Rename.
6. Select OK.

What to do next

If you have renamed the tag permanently:

• If the tag is used as a trigger, reassign the trigger.
• Restart the collector instance.
