MOXA MGate MB3170 Industrial Ethernet Gateway
The Moxa MGate MB3170 Connects Legacy Modbus Devices to Modern Ethernet Networks
Legacy equipment doesn't have to sit outside your network. The Moxa MGate MB3170 industrial Ethernet gateway connects a serial device to modern Ethernet systems, acting as a dependable Modbus TCP gateway between the two.
This MGate MB3170 gateway is trusted across marine, oil and gas, and factory automation applications, where real-time monitoring and precise control matter.
How the MGate MB3170 Bridges Legacy and Ethernet Networks
At its core, the MGate MB3170 works as a Modbus TCP to Modbus RTU converter. It functions as a Modbus protocol gateway, translating Modbus RTU/ASCII signals into Modbus TCP so older devices can join a modern network. As a serial-to-Ethernet gateway, it solves a common headache: legacy device integration, keeping older Modbus equipment operational without forcing a full hardware replacement.
This Modbus communication gateway handles protocol conversion automatically. Auto Device Routing maps the serial device to the Ethernet network without manual configuration, saving setup time and reducing the risk of configuration errors.
On the connectivity side, the gateway speaks the protocols that keep serial and Ethernet devices talking to each other. Modbus TCP Client/Server (Master/Slave) and Modbus RTU/ASCII Master/Slave modes cover both sides of the conversion. It includes 1 serial port with RS-232/422/485 support, runs on 12 to 48 VDC input power, and connects to up to 32 Modbus TCP clients/servers. SNMPv1/v2c/v3, HTTPS/TLS 1.2, and standard Modbus function codes round out its communication options. For facilities that need fiber connectivity or a wider temperature range, those variants are available elsewhere in the MGate MB3170 series.
