MPN #: MGate 5135
You have machines that speak Modbus, but your plant runs on EtherNet/IP. The gap can cause lost data, extra wiring, and costly downtime. The Moxa MGate 5135 1-Port Modbus RTU/TCP to EtherNet/IP Gateway closes that gap. It converts Modbus RTU/TCP traffic into EtherNet/IP so you can keep legacy devices while moving to a modern network. If you need reliable, real-time data without replacing equipment, this gateway is the answer.
Many factories struggle with two different communication standards. The problem is that data cannot travel between the old Modbus devices and the new EtherNet/IP controllers, leading to manual data entry or expensive protocol converters. This matters because every minute of manual work adds risk and cost. The Moxa gateway solves the issue by acting as a bridge that speaks both languages. It lets you keep your existing sensors, PLCs, and meters while integrating them into a single Ethernet-based control system.

We are retiring PICOPC Products MNHO-073, MNHO-048 and MNHO-043 and they have reached EOL (End Of Life) as we are introducing new products with better technology. We would recommend you to look into MNHO-095. For Untangle, pfSense, OPNsense, Windows 11, Proxmox VE etc. we recommend MNHO-095 whereas for Sophos, Kerio Control and Endian, we would recommend MNHO-069. (A complete list of supported OS can be found in each product's listing)
