Overview
The MGate MB3180 is the simplest way to put a serial Modbus device — a power meter, a flow computer, an old PLC — onto a Modbus TCP network. It converts transparently between Modbus TCP and RTU/ASCII, supports up to 31 serial slaves with automatic unit-ID routing, and accepts up to 16 TCP master connections. Configuration takes minutes through a web browser or the MGate Manager utility. Wide-temperature (-T) version available.
