The MB3170-G2 variant features a single software-selectable serial port (RS-232/422/485) and two 10/100Base-T(X) ports, providing flexibility for various network topologies. Use transparent conversion for simple pass-through, or switch to agent mode so the gateway polls your Modbus RTU/ASCII devices and serves cached values to SCADA—cutting wait times and improving determinism. The unit supports up to 32 Modbus TCP clients and 32 server connections, ensuring smooth multi-HMI or historian access. Web-based configuration over HTTPS, discovery tools and built-in Modbus diagnostics reduce commissioning time and speed fault-finding. Security features include TLS 1.2 and SNMPv3, with development aligned to IEC 62443-4-1.

Industrial design touches—dual 12–48 VDC inputs, a relay output and IP30 metal housing—enhance resilience in control panels. The operating range is -10 to +60°C, making it ideal for most indoor cabinets and sheltered field locations. If you later need fibre or isolation, the family offers pin-compatible options with 100Base-FX or SFP uplinks and 2 kV serial isolation. See page 6 for model specifics and page 1 for core features.

Specify MB3170-G2 today and we’ll help map your serial devices and optimise agent-mode polling for fast SCADA reads.
