Field Communicator
7.1
Overview
The Field Communicator is a communication interface device. It supports HART
and F
field.
The Field Communicator includes an LCD with touch-screen display and keypad.
Use the touch-screen or keypad to enter data into the Field Communicator.
Three terminals for the lead are on the top of the Field Communicator. The lead
set and terminals let you connect the Field Communicator to a device. An access
door ensures only one pair of terminals can be used at any time. Several markings
indicate which pair of terminals is for which protocol. F indicates the F
Fieldbus protocol, while H indicates the HART protocol.
The infrared port (IrDA) lets the Field Communicator interface with the PC. IrDA is
a PC interface supported for transfer of device descriptions (DD), software
updates, configurations, and application licenses. IrDA communications can either
be built into the PC or provided through a USB to IrDA adapter. The PC application
can either be AMS Suite or Easy Upgrade Programming Utility. The Field
Communicator must be in the Listen for PC mode when communicating through
IrDA.
Refer to the Field Communicator User Manual for details.

Field Communicator connections
7.2.1
Connecting to a HART
Connect the Field Communicator with the supplied lead set in parallel with the
device or load resistor,
sensitive. A minimum 250 ohms resistance must be present in the HART loop for
the Field Communicator to function properly.
WARNING
EXPLOSION
Explosions can result in death or serious injury.
Do not make connections to the Field Communicator's serial port, digital signal
line, or NiCad recharger jack in an explosive atmosphere.
