The Moxa MGate MB3180 is a 1-port Modbus gateway built to bridge Modbus serial devices into Modbus TCP systems. It’s the clean “single line” answer when you’ve got one Modbus RTU/ASCII segment to bring onto Ethernet without overbuying ports you won’t use.

Why We Love This Product

• Simple 1-port Modbus bridge for straightforward serial-to-Ethernet integrations
• Keeps proven Modbus field devices running while modernising the network layer
• Great value when you only have one Modbus serial segment to connect
• Reduces messy workarounds and makes future support far easier

How Our Customers Use It

• Connecting Modbus RTU meters, sensors, and drives into Modbus TCP SCADA systems
• Upgrading serial-only sites to allow remote access over IP networks
• Brownfield integrations where replacing Modbus devices isn’t justified
• Creating a cleaner architecture for monitoring and maintenance teams

Choosing Tips

• Choose MB3180 when you only need one Modbus serial port bridged into Modbus TCP
• If you have two serial segments now (or soon), MB3280 is the smarter pick to avoid adding a second gateway
• If you’re already managing multiple panels/segments, MB3480 reduces device sprawl with 4 ports
