To rename a tag, you must be a member of the administrator's
group with tag-level security.
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.
Important: You must only include tag name in the list of fields to
export.
In the Excel worksheet, to the right of the Tagname
column, insert a column named New Tagname.
For each tag that you want to rename, enter the new name in the New
Tagname column.
Important: You must specify a tag name in all the rows of the
New Tagname column. If you do not want to rename
any of those exported tags, you must delete that row.
If you want to rename the tags permanently, to the right of the New
Tagname column, insert a column named Permanent
Rename.
For each tag that you want to rename permanently, enter
TRUE in the Permanent Rename
column. For the remaining tags, enter FALSE.
Select Historian > Administration > Rename Tags.
A message appears, asking you to confirm that you want to rename the tags.
