Connect all Modbus devices over the Ethernet network…

Most host computers and newly developed PLCs support the Ethernet interface and run Modbus/TCP. NPort 6110 Modbus Gateway is needed to link discrete Serial Modbus Devices for data collection and control.

Each NPort 6110 supports Modbus/TCP over Ethernet, which allows up to 7 connections. The software configurable serial interface supports either RS-232 or RS-422/485. In RS-232/422 modes, NPort 6110 can be connected to 1 serial device. Under RS-485 mode, NPort 6110 supports up to 31 serial devices, which is the most popular application for factory floor applications.
