Field Communicator application

The Field Communicator application lets you configure HART and FOUNDATION fieldbus devices. (The fieldbus functionality requires a license.) You can do the following:

  • Power and connect to a HART transmitter, if the Trex unit has the Device Communicator Plus communication module. The Trex unit has an internal resistor, so you do not need to add a loop resistor.
  • Power and connect to a HART positioner, if the Trex unit has the Device Communicator Plus communication module.
  • Power and connect to the Smart Wireless THUMâ„¢ Adapter, if the Trex unit has the Device Communicator Plus communication module.
  • Power and connect to a FOUNDATION fieldbus device, if the Trex unit has the Device Communicator Plus communication module. The Trex unit provides power, power conditioning, and two terminators.
  • Connect to an externally-powered HART or FOUNDATION fieldbus device.
  • Use the internal resistors in the Trex unit when connecting to an externally-powered HART transmitter. The internal resistors in the Trex unit temporarily convert an externally-powered 4-20 mA current loop into a HART loop.
  • Save menu items from HART devices to a list of favorites for quick access.
  • Simulate a HART or FOUNDATION fieldbus device.
Note: The Field Communicator application can be used with the Device Communicator communication module or Device Communicator Plus communication module. However, the Trex unit cannot power a HART or FOUNDATION fieldbus device with the Device Communicator communication module.
