HART® commissioning
3.7.1 Variable mapping
Field communicator
The Variable Mapping menu displays the sequence of the process variables. Select 5 Variable
Re-Map to change this configuration. The 3144P 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 or terminal temperature must be selected .
The 3144P 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, First-Good
Temperature, Terminal Temperature, and Not Used . The primary variable is the 4–20 mA analog
signal.
3.7.2 Sensor configuration
Field communicator
Sensor configuration contains information for updating the sensor type, connections, units, and
damping.
3.7.3 Change type and connections
The Connections command allows the user to select the sensor type and the number of sensor
wires to be connected from the following list:

2-, 3-, or 4-wire Pt 100, Pt 200, Pt 500, Pt 1000
