Example of MODBUS addressing
If you want to assign SENCOM SA - MODBUS address 8 to mA2,
first assign MODBUS address 8 to Address CH1-3. Next if you want to assign Sensor 1-3 to
mA2, go to “Converter menu” > mA output > mA2 > Process parameter slot, and select.

MODBUS - Converter
FLXA402 as slave communicates with HOST devices, via MODBUS RS-485, Bluetooth, or
Ethernet (Modbus TCP/IP). Select a network system according to the hardware architecture you
use.
For further technical information on MODBUS, read
First of all, before Bluetooth paring with devices, you need to create Bluetooth device name with
up to 12 characters. The default is serial number of the device.
On each device of the network, “FLXA402- [Bluetooth device name]” is diaplayed.
[Bluetooth device name] is loaded on to the system display after the FLXA402 reboots.

HART setting
Configure HART setting. Select (PV), SV, TV, QV Device variables. PV is not displayed on HMI panel.
NOTE
PV is in conjunction with “Process parameter slot” “Process parameter” (see 4.3.1
Output )
selected at mA output mA1. If you change PV here, change the setting of mA output.
l
Loop Current Mode
For Point-to-Point, stay on the default “Enable”.
For Multi-drop-4 mA (fix), set “Disable”
“Enable”
mA1 output normal Loop current
“Disable”
mA1 output fixed 4mA, for Multi-drop
l
Network address
Point-to-Point stay on the default “0”.
Multi-drop
“1 to 63”, each devices should have different address each other.
mA output is fixed 4 mA.
