HART® commissioning
3.8.4 HART output
The HART Output command allows the user to make changes to the multidrop address, initiate
burst mode, or make changes to the burst options.
3.8.5 LCD display options
The LCD Display Option command sets the meter options, including engineering units and
decimal point. Change the LCD display settings to reflect necessary configuration parameters
when adding a LCD display or reconfiguring the transmitter. Transmitters without LCD displays
are shipped with the meter configuration set to “Not Used.”
3.9 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.
3.9.1 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.
3.9.2 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 8 characters in traditional Tag.
