The Moxa MGate MB3170-G2 is a 1-port Modbus gateway with RS-232/422/485 serial and dual Ethernet ports, built to connect Modbus RTU/ASCII devices to Modbus TCP networks without changing existing control logic. It supports transparent conversion for straightforward integrations or agent mode, where the gateway polls and caches device data to reduce latency for SCADA reads.

This MB3170-G2 copper model suits control cabinets and factory networks where standard Ethernet is preferred and dual-port networking enables cascading or dual-subnet designs. It also includes practical commissioning and maintenance support through the web console and built-in diagnostics and monitoring tools, helping speed up troubleshooting in live environments. For secure management, it supports HTTPS (TLS 1.2) and SNMPv3.

Choose MB3170-G2 when you need a compact, general-purpose serial-to-Ethernet Modbus gateway with industrial power resilience and straightforward deployment in standard temperature environments.
