Serial master devices talk to multiple Ethernet slave devices

Link the Serial Master device with Ethernet Slave devices…

Many HMI (Human Machine Interface) systems use a serial interface and are required to access a discrete DCS (Data Control System). These days however, more and more DCSs support Ethernet and run under Modbus/TCP slave mode.

In this case, NPort 6110 Modbus Gateway is the ideal solution to link the HMI to distributed DCSs over an Ethernet network. Up to 4 Modbus/TCP slave devices are supported by each NPort 6110.
