Precaution on DD file revision and device revision
When using HART communication of a FLXA202/FLXA21, it is necessary to use the DD file
that matches the revision of the FLXA202/FLXA21 device used. Make sure to check they match
before use, as follows.
(1) Checking the FLXA202/FLXA21 device revision
Call up the detailed settings screen on the front display panel or access the Zoom display on
the setup tool.
Select “HOUSING ASSY”.
The device revision number will be displayed as Hart Device Revision.
(2) Checking the DD file revision
DD files are stored with filenames beginning with a four-digit number such as 0102.xxxdd.
The first two digits, 01 in the example above, indicate the device revision. The following two
digits, 02 in the example above, indicate the DD revision.
Use the latest revision of the DD file that matches the device revision.

Connecting Setup Tool
You can connect the setup tool to any interconnection terminals such as those in the central
control room, a converter’s junction box, or somewhere within the transmission loop as long as
the load resistance between the power supply and the terminals to which you want to connect the
setup tool is 250 ohms or larger. Connect the setup tool in parallel with the load resistance. It is
polarity-insensitive.

Functions Available via HART Communication
Almost all FLXA202/FLXA21 functions accessible via the front panel display of the FLXA202/
FLXA21 are available via HART communication. For details of the functions, see the descriptions
for panel display contents. Some functions, however, are not available via HART communication,
and some are available only via HART communication.
