Model F-5500
COMMUNICATIONS
HART Protocol
Product Overview
HART communication is transmitted over the F-5500 4-20mA flow output signal
and can be monitored and configured using a HART master device or a hand-held
communicator.
Process Flow Rate 4-20mA Analog Output
The 4-20mA output of the F-5500 HART represents the process flow rate
measurement, linearized and scaled according to the configured range of the
instrument. This output corresponds to the Primary Variable. HART Communication is
supported on this loop.
The 4-20mA output of the F-5500 should be configured for flow rate when using
HART. If the 4-20mA output is set to report temperature, HART communication will
report the 4-20mA value for temperature rather than flow.
HART Indicators
LED indicator LP3 cycles on and off to indicate that the F-5500 is operating.
LED indicator LP2 blinks when HART signals are received and LP1 blinks when HART
signals are transmitted (if nothing is connected to the 4-20mA output, LP2 will be on
continuously).
F-5500 HART Communication Setup
HART communication must be selected in the F-5500 Serial Communication menu for
HART communication to operate. When this communication parameter is changed,
power to the F-5500 must be cycled for it to take effect.
Device Variables
This device does not expose any Device Variables.
Dynamic Variables
Four Dynamic Variables are implemented.
