Industrial Protocol Gateways From ManuAuto 
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 — 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; 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 bottlenecks 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; 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.

Choosing the Right Protocol Gateway for Your Application

Not every gateway in this lineup does the same job. The right model depends on which two protocols need to talk to each other, how many devices sit on each side, and where the unit will physically live.

Modbus RTU/ASCII to Modbus TCP

The most common starting point for bringing legacy serial devices onto a modern Ethernet-based SCADA system. Models range from single-port units to gateways with up to 16 serial ports for larger device counts.

EtherNet/IP and multi-protocol Ethernet gateways

for factory floors running EtherNet/IP, PROFINET, and Modbus TCP side by side, where equipment from different controller vendors needs to share the same network.

Modbus to PROFINET

for connecting Modbus-based instrumentation and drives into a PROFINET-based automation cell without replacing the field devices.

CANopen/J1939 gateways

for mobile and off-highway equipment, gensets, and vehicle-bus systems that need to report into a Modbus TCP, EtherNet/IP, or PROFINET network.

Modbus to BACnet/IP

for tying industrial metering and monitoring equipment into a building automation system.

How do I know which one fits my application?

It comes down to the protocols on each side, the number of devices, the physical environment (temperature range, DIN rail vs panel mount), and how many ports the integration actually needs. ManuAuto's engineering team, working with brands like Moxa's MGate lineup, matches the model to the application before anything ships. So the gateway that arrives fits the job, not just the closest match on a spec sheet.
