The data field displays the instrument tag name template that is based on the tag naming convention defined by the Domain Administrator for the current <unit>. In the alphanumeric and the numeric parts of the name, you can type any character (letters, digits, spaces, and so forth). You can customize the tag name template to set a default, but only the Domain Administrator can change the naming conventions. For more details see Customize Tag Name.
