TI 12A01F01-61EN Nov. 20, 2018-00
This document describes HART communication by FLXA402 4-Wire Converter.
Before communicating using the HART protocol, refer to the User’s Manual for the FLXA402
4-Wire Converter Operation of Converter IM 12A01A03-01EN for details of the parameters.
For latest User’s Manual, download it from our website or scan QR code.

1. General
HART Communication superimposes specic waveforms called HART Communication
waveforms on the 4–20 mA analog signal from a FLXA402 to enable remote intercommunication
between the online FLXA402 and a setup tool (*).
*: FieldMate, Plant Resource Manager (PRM), or a handheld HART communicator may be used as the setup tool.
Note: When using FieldMate or a 375 Field Communicator, make sure you use the following or greater version of the product.
FieldMate R3.04.00 + Device Files R3.09.00
HART is a registered trademark of FIELD COMM GROUP. https://www.eldcommgroup.org/
1.1 InstallingDDles
To enable HART communication between a FLXA402 and setup tool, the device description
(DD) le of the FLXA402 needs to be installed in the setup tool. The DD le contains the HART
communication details and menu congurations specic to the FLXA402.
FieldMate is provided with the latest versions of DD les at the time when sold. The current
version of DD les can be downloaded from the following site (*):
YOKOGAWA : http://www.yokogawa.com/an/download/an-dl-eldbus-001en.htm
(*): The URL s is subject to change without prior notice. If the URL cannot be accessed, consult your nearest sales o󰀩ce or the
agency from which you purchased the product.
nBefore using FieldMate
Before using FieldMate, check the revision of Device Files.

nInstalling DD File
For how to install the DD le, see the respective documentation for the setup tool you use.
For FieldMate R3.04.00+Device Files R3.09.00, installing DD File is not required.
nConnecting Setup Tool
Connect HART modem at the both ends of the load resistance which is 250 ohms or larger and is
installed between the setup tool terminals and mA1.
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.
1.2 Functions Available via HART
Communication
FLXA402 via Hart communication enables the following settings: Error settings (4.7), mA output
settings (4.3), Contact input settings (4.2), HART setting (4.6.2). Information on the sensor
settings or calibration are available as Read only. The numbers in the parentheses correspond
the section number in the User’s Manual IM 12A01F01-03EN.

1.2.1 Multi-drop mode
Multiple number of eld devices put in multi-drop mode can be connected in parallel on a single
cable. To enable the multi-drop mode, set the device address to a unique number from 1 to 63.
NOTE
Multi-drop mode communication requires the devices on the link to be given unique device
addresses for polling (polling addresses). If the same address is set in two or more devices,
correct communication is disabled.
Canceling multi-drop mode:
To release a device from the multi-drop mode, set the polling address to zero.
1.2.2 Write protection
Turning the slide switches ON disables the setting via HART communication (default: OFF).
If you create a password at "Setting" on the display, it protects HART setting, disabling writing
over HART parameters. See 1.3 in IM 12A01F01-03EN Operation of Converter

1.3 Precaution
lSetting on the FLXA402 and a setup tool
HART/MODBUS network/the panel operation, they cannot be established simultaneously to
change the setting of FLXA402.
During the panel operation or the setting via MODBUS network, establishing HART connection
issues a fail.
We recommend mA output to be on Manual Hold status while you are changing the setting.
(See 3.7 Hold operation (manual Hold) on IM 12A01F01-03EN Operation of Converter.
lAccess to parameters (Printout, Up/Download of parameters)
The large number of parameters are congured in FLXA402. Therefore, it may take several
minutes to carry our operation by using a lot of parameters.
lNote on Display
Update the menu display whenever the setting of FLXA402 is revised.
