MR-GW
Modbus RTU / Modbus TCP Gateway
Description
MR-(F)-GW is a compact Modbus RTU / Modbus TCP Gateway. The MR-Gateway enables bidirectional data exchange between Modbus RTU fieldbus devices and a Modbus TCP master (client). The MR-(F)-GW can be operated 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-pole terminals on the front of the device and a jumper plug. An integrated web server is used for parameter settings, management and monitoring of the two interfaces (Ethernet / RS485). The web interface is also used to update the firmware. The MR-Gateway is suitable for decentralised mounting in electrical sub-distribution boards or in control cabinets on TH35 mounting rails in accordance with IEC 60715.
- Simultaneous access from 32 Modbus TCP clients
- Bidirectional exchange of data between Modbus RTU Slave devices and a Modbus TCP Master (client)
- Protocol: Modbus RTU over TCP (Transparent gateway), Modbus TCP/IP v1.0b, HTTP 1.0
- Integrated web server
- Intuitive and software-independent TCP configuration via web interface
- Simple device search of METZ CONNECT Modbus RTU devices on the RS485 bus
- Fast connection of METZ CONNECT Modbus RTU devices via proven jumper plug technology
- Galvanic 3-way isolation (RS485- Ethernet-power supply)
- Status monitoring of TCP and RS485 communication

FAQ's
Can other devices (not from Metz Connect) also be used with the MR-GW?
Yes, via the custom query.
Is the terminal block type 259 (110369) delivered with the MR-GW?
No, there are terminals on the device for this purpose (24V, GND, B+, A-).
Can the MR-GW be reset to factory settings?
Yes, via the web interface.
How many bus devices can I access with the MR-GW?
32, with 1 unit load per participant, most of our I/Os only have 0.125 load, which means that much more are possible depending on the conditions.
Can our Modbus I/Os also use the web interface (configuration tool) without the MR-GW?
No.
