What is an MGate (Protocol Gateway)?

MGate protocol gateways act as translators between different industrial protocols. They enable seamless interoperability and optimize data traffic for better SCADA performance. The latest MGate MB3x70-G2 Series further speeds up system response times via Agent Mode and effortlessly connects nonstandard assets to Ethernet networks without complex coding through built-in proprietary serial support.
