What Is an MGate (Protocol Gateway)?

MGate protocol gateways provide protocol translation between industrial devices operating on different communication standards. This helps improve interoperability while supporting more efficient data exchange within SCADA and OT environments. The latest MGate MB3x70-G2 Series further improves communication performance using Agent ModeActive Polling: Agent mode polls operational data in the background and serves cached information directly to SCADA systems, helping minimize latency compared with transparent gateway operation. and supports the integration of nonstandard serial equipment into Ethernet networks through built-in proprietary serialNo PLC Programming: Proprietary serial support simplifies integration by allowing custom serial equipment to connect to Ethernet networks without changing PLC programs. functionality.

This illustration shows how the MGate Series serves as a reliable link between serial field devices and Ethernet-based SCADA or HMI systems. By translating Protocol A used by field equipment into Protocol B required by supervisory platforms, the gateway enables stable, low-latency communication throughout industrial networks. This approach allows engineers and system integrators to connect a wide range of assets without making changes to existing PLC programs, helping improve operational efficiency while enhancing network interoperability.


The MGate product family offers a comprehensive portfolio of industrial connectivity solutions designed for engineers and system integrators. Whether the goal is to connect serial devices to Ethernet networks, enable seamless communication between different industrial protocols, or integrate USB-based equipment, MGate gateways simplify system integration, improve network reliability, and streamline data exchange across industrial automation environments. The portfolio includes serial device servers for Ethernet connectivity, MGate G2 protocol gateways for secure and efficient protocol conversion, and USB-to-serial converters that provide flexible support for a wide variety of devices.
