    Segment

    Unit

    UNIT NUMBER

    Instrument Type

    INSTRUMENT TYPE

    Tag Number

    COMPONENT NUMBER

    Tag Number

    COMPONENT SUFFIX

  6. Enter separators before the second, third and fourth tag segments and modify the string lengths in the Length column as shown:

    • The Sample field shows the changes in the tag structure as you make your naming convention definitions.

    • The first segment in the sequence becomes the tag prefix. In the current naming convention, the unit number 101 will be the prefix of every instrument you create in the current unit.

    • You can only change the tag convention for a unit as long as no instruments are defined for the unit.
