AirGate-Modbus
NOVUS AUTOMATION 7/22
LONG REACH APPLICATION
In seeking to expand the network, in order to obtain a greater distance, it is possible to assemble a tree shaped topology.
As exemplified in Fig. 8, to expand the network, an AirGate-Modbus configured as a RS485-SLAVES (Firmware >
1.23) was inserted with the same PAN ID (5670). In another segment, two AirGates were assembled using the RS485
interfaces, an AirGate-Modbus operating the RS485-SLAVES mode, and an AirGate-Modbus operating in RS485-
MASTER mode. In this segment a new PAN ID (5671) was created, starting a new star network.
