3.10 Device information
Access the transmitter information variables online using the Field Communicator or other suitable
communications device. The following is a list of transmitter information variables, including device
identifiers, factory-set configuration variables, and other information. A description of each variable, the
corresponding fast key sequence, and a review are provided.
3.10.1 Tag
The Tag variable is the easiest way to identify and distinguish between transmitters in multi-transmitter
environments. It is used to label transmitters electronically according to the requirements of the
application. The defined tag is automatically displayed when a HART-based communicator establishes
contact with the transmitter at power-up. The tag may be up to eight characters long and has no impact
on the primary variable readings of the transmitter.
3.10.2 Long tag
Long Tag is similar to Tag. The long tag is different in that the Long tag can be up to 32 Characters
instead of the eight characters in traditional Tag.
3.10.3 Date
The Date command is a user-defined variable that provides a place to save the date of the last revision of
configuration information. It has no impact on the operation of the transmitter or the HART-based
communicator.
3.10.4 Descriptor
The Descriptor variable provides a longer user-defined electronic label to assist with more specific
transmitter identification than is available with tag. The descriptor may be up to 16 characters long and
has no impact on the operation of the transmitter or the HART-based communicator.
