The MGate MB3270-G2 series are Moxa's next-generation Modbus gateways that convert between Modbus TCP, RTU, ASCII and proprietary/extended Modbus serial protocols. These gateways transparently convert protocols, actively poll connected devices and cache data in memory. Enabling SCADA systems to retrieve Modbus data directly from the gateway instead of waiting for all Modbus devices to respond, greatly increasing communication performance.

Moxa has developed the MGate Series using the IEC 62443-4-1 secure development life-cycle process ensuring secure connections and management of these gateways within industrial networks.

MGate MB3270-G2 series offers versatile installation options for diverse mounting and wiring requirements. Its rugged design is suitable for harsh environments. Moxa MGate MB3270-G2 series includes configuration and troubleshooting tools to ease maintenance effort.

High Performance Modbus Conversion
Moxa MGate MB3170-G2 gateways operate in either transparent (direct protocol conversion) or agent (polling and caching) mode. Transparent mode converts protocols on a per-request basis. But for larger Modbus systems or when lower latency is needed, agent mode greatly enhances SCADA communication by directly accessing the gateway’s cache.

Flexible Modbus Conversion for Systems Integration
Supporting dual subnet network configuration, Moxa MGate seamlessly integrates Modbus TCP with Modbus RTU/ASCII without disrupting existing systems. 

With multiple serial port models, MGate simultaneously converts between Modbus serial and Modbus TCP, as well as serial-to-serial and TCP-to-TCP. Even with legacy serial, or COM port-based software, the MGate’s Real COM mode enables communication through Ethernet TCP with no software adjustments. 

Beyond standard Modbus RTU and ASCII, the MGate also converts proprietary and extended Modbus serial protocols, eliminating the need for custom development or additional equipment and ensuring near-universal Modbus system compatibility. The MGate-G2 is capable of simultaneous conversion from proprietary serial and Modbus serial to Modbus TCP.
