Exclude tags from the tag check

When you select Check all tags on the Tag Collection Editor or Check All on the main External Data Manager window, the software checks the tags to ensure they meet the following criteria:

• The tag exists on the server.

• The tag's data type corresponds to real values.

• The tag mapping is complete.

If a tag doesn't meet this criteria, warning or error badges appear on the tag and on the associated tag collection.

You may have tags in a tag collection that are placeholders and aren't completely configured. These tags can cause warnings to appear for the tag collections when you perform a tag check. You can avoid these warnings by excluding the tags from the tag check.

Excluded tags also do not participate in the following tag operations:

• Read

• Screen

• Set

• Update Last Good

• Get

• Write

Exclude a tag from the tag check

2. Select Define.

   The Tag Collection Editor appears.

3. In the Tags Configuration section, clear the checkbox for the tag that you want to exclude.

   The Status badge for the tag disappears, and the tag no longer participates in the tag check.
