2.6.1 Mapping the HART variables
Mapping HART variables using the Field Communicator
The "Variable Mapping" menu displays the sequence of the process variables. Select the
sequence below to change this configuration. The transmitter single sensor input
configuration screens allow selection of the primary variable (PV) and the secondary
variable (SV). When the Select PV screen appears, Snsr 1 must be selected.
The transmitter dual-sensor option configuration screens allow selection of the Primary
Variable (PV), Secondary Variable (SV), Tertiary Variable (TV), and Quaternary Variable
(QV). Variable choices are Sensor 1, Sensor 2, Differential Temperature, Average
Temperature, Terminal Temperature, and Not Used. The 4–20 mA analog signal
represents the Primary Variable.
From the HOME screen, enter the Fast Key sequence.
