MODBUS Communication 2
TI 12A01F01-62EN
This document describes MODBUS communication by the FLXA402 4-Wire Converter.
Before communicating using the MODBUS protocol, refer to the User’s Manual of the FLXA402
4-Wire Converter (IM 12A01F031-03EN Operation of converter) for details of the parameters.
For latest User’s Manual, download it from our website or scan QR code.
http://www.yokogawa.com/an/xa402/download/
1. General
FLXA402 configures or obtains process data by using MODBUS/TCP protocol on physical
application: Ethernet, RS485.
MODBUS RTU is supported but not ASII.
1.1 MODBUS setup
lEthernet
FLXA402 uses Modbus/TCP, connection port 502.
For MODBUS/TCP, IP address, subnet mask, default gateway or DHCP should be set in
advance from HMI device.
The Ethernet conguration is reected onto the system, after FLXA402 reboots.
lRS485
FLXA402 communicates via RS485 MODBUS.
The following list shows the required setting by HMI to establish communication between a
master device and FLXA402 via RS485 MODBUS.
Converter address: 1 to 247 (initial value 1)
Transmission speed: 9600[bps], 38400[bps], 115200[bps]
Parity : Even, Odd, None
When Parity is Even or Odd, Stop bit is 1bit, when None, Stop bit is 2 bit.
Even or Odd is recommended for Parity.
Stop bit: 1 bit
Parity: Even
Mode: RTU

1.2 MODBUS master
lMaintenance
YOKOGAWA FieldMate is recommended for FLXA402 conguration via MODBUS.
FieldMate allows
• easy calibration by handheld FieldMate
• help function to setup temperature comp. table etc.
• remote control via Ethernet
• wide panel operation, larger than FLXA402
lData memory
YOKOGAWA GX series with RS485 MODBUS are recommended for process data saving.
MODBUS communication enables to store larger amount of process data than FLXA402 mA
output.

Exception responses
Exception Code Name Meaning
0x01 Illegal Function The Function Code received in the query is not an
allowable action for the server or slave.
0x02 Illegal Data Address The data address received in the query is not an
allowable address for the server or slave.
0x03 Illegal Data Values The value contained in the query data eld is not an
allowable value for the server or slave.
If parameter setting fails because the setting is out of the range, Exception code 0x03 is replied
indicating a fail setting. When multiple parameters are to be set, even a single forbidden setting
makes all the other parameter setting fail.

1.4 MODBUS communication
The following must be cared when master devices other than FieldMate are used.
lMODBUS response timing
IR (Input Register) response to IR Read request within 50 ms after FLXA402 receives the
message. To the other request, FLXA402 replies within 100 ms after it receives the request.
Another request must be sent at least 100 ms after the last response was received from
FLXA402.
<50ms >100ms <100ms
User
FLXA402
HR RequestIR Request
IR： Input Register
HR： Holding Register
HR ResponseIR Response
lInput Register renewal cycle
Process value sent in Input Register is renewed every 500 ms. It is better to Read the process
value every 500 ms.
lHow to change the setting
• Turn ON Coil register 31 to grant access authority
• Change the Coil/Holding register
• Turn OFF the coil to restrict the access again after the renewal completes.
NOTE
Even if you have no access authority, you can register WASH Start/Stop, WASH Recovery stop.
For other parameters, follow the procedure above. If you try to write the parameters without
access, an error response (Error code 03) is replied.
NOTE
When FLXA402 has access to measured data, you cannot set devices by using HMI or other
devices on the network. Even after FLXA402 loses access, this situation remains unchanged for
3 seconds.
NOTE
When no message comes for 30 seconds from MODBUS master which has access, the access
turns OFF automatically.

MODBUS Communication 5
TI 12A01F01-62EN
1.5 MODBUS password
Entering password on “MODBUS password” protects parameter setting and prohibits data input
except for “cancel MODBUS password” and “gain access authority.”
To be allowed to input data, go to password setting mode. Enter the password you created for
“cancel MODBUS password” then you are allowed to input.
1.6 How to change SENCOM SA address
SENCOM SA*sensor address are all 1 at the time of purchase. If you try to connect multiple
SENCOM SA before you change the address, the communication fails. When you change
SENCOM SA sensor, you have to connect the SENCOM SA one by one and change the
address.
*: SENCOM SA refers to SA11, some sensors connected to SA11.
SA11 is used when -S5 (SENCOM SA) is specied for FLXA402 1st/2nd input.
1.7 Connection
lEthernet
On the FLXA402 network, Ethernet MODBUS allows 2 sessions.
First session provides communication to Read process value periodically by connecting
constantly.
Second session is for maintenance only when maintenance is required. FieldMate is
recommended for 2nd session.

lRS485
FLXA402 communicates with one MODBUS master via RS485 MODBUS. RS485 is connected
constantly and provides communication for reading process value.

NOTE
Although connections other than these mentioned above are available, they might disable
obtaining process value, if Read and setting change are implemented in a single session/
communication.

MODBUS address are assigned to designated sensor connection number to input sensor
measured value. Other address, which are not assigned to the sensor connection, shows “0”.
<Example>
When:
Sensor1: PH sensor module, Sensor2: SC sensor module
Sensor connection number 1-1 is PH, Sensor connection number 2-1 is SC.
This time,
Modbus address 1000 to 1023 are assigned to input of measured value from Sensor1 PH sensor
module.
Modbus address 1400 to 1425 are assigned to input of measured value from Sensor2 SC sensor
module.
“0” is read on other address : 1024-1063, 1100-1163, 1200-1263, 1300-1363, 1426-1463, 1500-

For further information, see section 4.7 “Error settings” in the User’s Manual IM 12A01F01-03EN
Operation of Converter.
nError settings
See Chapter 3 for bit assignment.
Register (by bit) 4 alarm types :
Measurement alarm, I/O alarm, Maintenance status, Setting error,
according to NE107 :
Failure (F), Function check (S), Out of specication (C), Maintenance required (M), and (O󰀨), (N).
If you assign bit “0” to an alarm , the alarm reads “O󰀨”.
If you assign a bit number to multiple alarms simultaneously, priority in the validity goes
F>S>C>M.
CAUTION
When you want to revise an alarm priority from high to low, rst provide bit “0” with the lower one,
then give “1” to the higher one.
