Industrial Protocol Gateways

Industrial Protocol Gateways From ManuAuto,Β 
the Reliable Supply Choice for Canada and North America

Protocol converters, industrial communication gateways, and fieldbus gateways for Modbus, PROFINET, EtherNet/IP, IEC 61850, and DNP3, featuring Moxa β€” in stock and ready to ship across Canada, the United States, and worldwide through ManuAuto.

Industrial facilities rarely run on a single communication protocol. An industrial protocol gateway, also known as a protocol converter, industrial communication gateway, serial-to-Ethernet gateway, or fieldbus gateway, translates data between incompatible standards, connecting existing assets to modern networks instead of replacing equipment that still works.

Solving Protocol Incompatibility in Industrial Networks

Protocol incompatibility isn't a rare edge case β€” it's the default condition of most industrial networks, and it stalls integration projects across manufacturing and factory automation, energy and power systems, oil, gas, and mining, transportation (rail, traffic, and EV infrastructure), water and wastewater management, marine and port infrastructure, and smart city and industrial IoT projects.

What This Looks Like in Practice

Legacy System Communication Issues

Equipment installed decades ago that can't natively reach a modern SCADA platform.

Multi-protocol Integration Problems

Modbus, PROFINET, and EtherNet/IP devices that all need to share the same data.

Industrial Network Communication Gaps

Field devices and monitoring platforms that were never designed to talk to each other.

Inefficient Data Transmission

Serial-only equipment bottlenecking data that modern networks need in real time.

Lack of System Interoperability

Isolated data that never reaches the SCADA or monitoring system that needs it.

How Industrial Protocol Translation Works

A protocol gateway sits between two communication systems, receives data in one protocol, maps it internally, and re-presents it in the protocol the destination system understands β€” a legacy Modbus RTU device, for example, can be converted to Modbus TCP so a modern SCADA platform can read it, without rewiring or controller replacement. This same mechanism underlies most network compatibility work in industrial systems today: protocol conversion, legacy system integration, SCADA communication bridging, and industrial IoT connectivity.

Moxa, a Protocol Gateway Brand ManuAuto Stocks in Depth

Several manufacturers build industrial protocol gateways. Among the brands ManuAuto carries, Moxa stands out for its MGate lineup, which covers one of the widest ranges of industrial communication standards in a single, purpose-built, industrial-grade product family β€” which is why ManuAuto keeps a deeper inventory of Moxa gateways than any other brand in this category.
