Metz Connect Modbus TCP Gateway

The MR-(F)-GW is a compact Modbus RTU / Modbus TCP gateway. It enables bidirectional data exchange between Modbus RTU field devices and a Modbus TCP master (client). The MR-(F)-GW can operate in two modes: either as a transparent gateway in Modbus RTU over TCP mode or as a protocol converter (Modbus TCP mode).

The MR-Gateway can be connected to METZ CONNECT Modbus RTU devices via two 4-pin terminal blocks on the front of the device and a bridge connector. An integrated web server is used for parameterization, management, and monitoring of the two interfaces (Ethernet / RS485). The web interface is also used for firmware updates.

The MR-Gateway is suitable for decentralized installation in electrical sub-distributors or in cabinets on TH35 mounting rails according to IEC 60715. It allows simultaneous access from 32 Modbus TCP clients and bidirectional data exchange between Modbus RTU slave devices and a Modbus TCP master (client).

Supported protocols include Modbus RTU over TCP (transparent gateway), Modbus TCP/IP v1.0b, and HTTP 1.0. The intuitive and software-independent configuration is done via the web interface. There is a simple device search for METZ CONNECT Modbus RTU devices on the RS485 bus and a quick connection of METZ CONNECT Modbus RTU devices using proven bridge connector technology.

The device offers galvanic 3-way isolation (RS485-Ethernet-Power supply) as well as status monitoring of TCP and RS485 communication.
