Foundation Fieldbus an instrument that is associated with a Foundation Fieldbus segment.

Tag number
Enables you to type the name of a new tag number. Use the Tab key or the left and right arrow keys to move the cursor to the next place. You can make your corrections or changes by overwriting the existing values. Alternatively, you can select the characters with the mouse pointer and then type the new content.
The data field displays the tag number name template which is based on the tag naming convention defined by the Domain Administrator for the current <unit>. For the alphanumeric part of the name, you can type any character (letters, digits, spaces, and so forth.). For the numeric part of the name, you can use only digits (0 to 9). You can customize the tag number name template to set a default, but only the Domain Administrator can change the naming conventions.
