MOXA MGate MB3270-G2 Industrial Ethernet Gateway

MOXA MGate MB3270-G2 INTRODUCTION

The MGate MB3170-G2, MB3270-G2, and MB3470-G2 are new-generation Modbus gateways that convert between Modbus TCP, RTU, ASCII, and even proprietary or extended Modbus serial protocols. These MGate gateways transparently convert protocols, actively poll connected devices, and cache data in memory. These capabilities make it possible for 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.

In addition, the user experience is enhanced by versatile installation options that accommodate diverse mounting and wiring requirements, a rugged design suitable for harsh environments, and easy-to-use configuration and troubleshooting tools for quick maintenance.

High-performance Modbus Conversion

MGate MB3170-G2/MB3270-G2/MB3470-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 Various Systems

Supporting dual subnet network configuration, the MGate seamlessly integrates Modbus TCP with Modbus RTU/ASCII without disrupting existing systems. With multiple serial port models, the 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.

Intuitive Configuration and Minimal Maintenance

Downtime during maintenance can be costly. System alerts often require contacting vendors, prolonging troubleshooting due to information gathering and consultations. MGate-G2 gateways streamline this process by providing comprehensive troubleshooting information for rapid issue identification. One-click diagnostics gather all necessary data for technical support, empowering users to efficiently resolve issues and drastically reduce downtime.
