The Moxa MGate 5105-MB-EIP is a specialised gateway for bridging Modbus (RTU/ASCII/TCP) devices into EtherNet/IP environments, with MQTT support for modern data workflows. Rated for 0 to 60°C operation, it’s designed for industrial sites that need to connect legacy Modbus assets into EtherNet/IP systems without a full rip-and-replace.

Why We Love This Product

• Bridges Modbus RTU/ASCII/TCP into EtherNet/IP—ideal for mixed-protocol environments
• MQTT support helps enable more modern IIoT-style data publishing and integration
• 0 to 60°C operating range suits typical industrial cabinet deployments
• Purpose-built for “make Modbus talk to EtherNet/IP” projects with fewer compromises

How Our Customers Use It

• Integrating Modbus instruments and RTUs into EtherNet/IP PLC and control environments
• Linking legacy Modbus assets into modern OT networks and reporting layers
• Protocol bridging in brownfield plants where Modbus remains everywhere
• Creating a stepping stone toward IIoT data flows without replacing field devices

Choosing Tips

• Choose 5105-MB-EIP when the target system is EtherNet/IP (not just Modbus TCP)
• If you only need Modbus serial-to-Modbus TCP bridging, an MGate MB3xxx model is usually the simpler fit
• If you don’t need MQTT, choose based on protocol requirements first—MQTT is a bonus, not the core reason to buy
