11. SYSTEM INFORMATION COLLECTION VIA MODBUS
11.1 MODBUS COMMUNICATION PORT SETPOINTS
Modbus communication port are integrated in control panel. This provides communication from the control panel
to a field Modbus bus network. When powered, the water system will be able to communicate via the secondary
terminals labeled XT20-1A, XT20-1B, and XT20-G as a slave device.
Recommended Modbus cable has twisted-pair wires having an aluminum/mylar foil shield with drain wire.
11.2 VIEWING/SETTING MODBUS SETPOINTS
Modbus ID address can be viewed and set from the LCD display in setups mode - SETUP 17: "System ID Num-
ber" (1-255). Control panel are shipped with set default address of 001.
Modbus Settings: 9600 bits/second baud rate, even parity, and 1 stop bit.
11.3 NETWORK COMMUNICATION PROTOCOL
Only the Modbus RTU communication mode is recognized by the Control panel. The Control Panel can support
65 registers (130 data bytes) only in a single Modbus transaction. The Control panel responds to a limited number
of Modbus function codes. These are function codes 03 (Read Holding Registers) and 06 (Write Holding Regis-
ters).
Reading is carried out by one sending of all registers from address 0000 to address 0064. Writing is carried
in register with address 0000, which is used to write Control Word.
