The MGate MB3170-G2, MB3270-G2, and MB3470-G2 are new-generationModbus gateways that convert between Modbus TCP, RTU, ASCII, and evenproprietary or extended Modbus serial protocols. These MGate gatewaystransparently convert protocols, actively poll connected devices,and cache data in memory. These capabilities make it possible forSCADA systems to retrieve Modbus data directly from the gateway insteadof waiting for all Modbus devices to respond, greatly increasing communicationperformance.
Moxa has developedthe MGate Series using the IEC 62443-4-1 secure development life-cycleprocess ensuring secure connections and management of these gatewayswithin industrial networks.
In addition, the user experience is enhanced by versatileinstallation options that accommodate diverse mounting and wiringrequirements, a rugged design suitable for harsh environments, andeasy-to-use configuration and troubleshooting tools for quick maintenance.
MGate MB3170-G2/MB3270-G2/MB3470-G2 gateways operatein either transparent (direct protocol conversion) or agent (pollingand caching) mode. Transparent mode converts protocols on a per-requestbasis. But for larger Modbus systems or when lower latency is needed,agent mode greatly enhances SCADA communication by directly accessingthe gateway’s cache.
Supporting dual subnet network configuration, the MGateseamlessly integrates Modbus TCP with Modbus RTU/ASCII without disruptingexisting systems. With multiple serial port models, the MGate simultaneouslyconverts between Modbus serial and Modbus TCP, as well as serial-to-serialand TCP-to-TCP. Even with legacy serial, or COM port-based software,the MGate’s Real COM mode enables communication through Ethernet TCPwith 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 equipmentand ensuring near-universal Modbus system compatibility. The MGate-G2is capable of simultaneous conversion from proprietary serial andModbus serial to Modbus TCP.
Downtime during maintenance can be costly. System alertsoften require contacting vendors, prolonging troubleshooting due toinformation gathering and consultations. MGate-G2 gateways streamlinethis process by providing comprehensive troubleshooting informationfor rapid issue identification. One-click diagnostics gather all necessarydata for technical support, empowering users to efficiently resolveissues and drastically reduce downtime.
