PrecautiononDDlerevisionanddevicerevision
When using HART communication of a FLXA202/FLXA21, it is necessary to use the DD le
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 le revision
DD les are stored with lenames beginning with a four-digit number such as 0102.xxxdd.
The rst 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 le that matches the device revision.
l ConnectingSetupTool
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.
n FunctionsAvailableviaHARTCommunication
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.
