MODBUS I/O ASSIGNMENT■ MODBUS NODE ADDRESS 255
By sending Modbus query of node address 255 from Modbus/TCP master device connected to the unit, it is possible to perform
I/O operations for the unit’s lamps and buzzers. The unit sends a response to Modbus/TCP master device that sent the query.

■ MODBUS NODE ADDRESSES 1 – 247
When Modbus query of Modbus node address 1 to 247 is sent from Modbus/TCP master device connected to the unit, it is transferred to a wireless device (child) that is connected to the unit via 900 MHz band wireless communication, then a response fromthe wireless device (child) is sent to Modbus/TCP master device that sent the query.
