A UTag (short for Universal Tag Name) is comprised of a tag’s location, source, and name, like so: “LOCATION.SOURCE.TAGNAME”. See [Adding Tags to Displays](/v1/docs/adding-tags-to-displays) for details on using the tag field. ![](https://cdn.document360.io/59db2ca4-e512-446a-a143-a7c626447812/Images/Documentation/image030_001.jpg) **Read Only:** If checked, the tag field is not modifiable.
