What Is HART Communication?

n
HART Communication superimposes specific waveforms called HART Communication
waveforms on the 4–20 mA analog signal from a FLXA202/FLXA21 to enable remote
intercommunication between the online FLXA202/FLXA21 and a setup tool (*).
*: FieldMate, Plant Resource Manager (PRM), or a handheld HART communicator such as the 375 Field Communicator may be
used as the setup tool.
Note: When using FieldMate or a 375 Field Communicator, make sure you use the following versions or later:
FieldMate:
FieldMate R2.02.00 + Device Files R3.01.01

n Downloading and installing DD files
To enable HART communication between a FLXA202/FLXA21 and setup tool, the device
description (DD) file of the FLXA202/FLXA21 needs to be installed in the setup tool. The DD file
contains the HART communication details and menu configurations specific to the FLXA202/
FLXA21.
FieldMate contains the latest versions of DD files at the time when sold. When using FieldMate,
the latest DD files updated since you purchased the product can be downloaded from the
following sites (*):
