Gateway/ Couplers

How to Choose an Industrial Communication Gateway

Selecting an industrial gateway or protocol converter depends on the devices that need to communicate, the networks involved and the data to be exchanged. Not all gateways perform the same functions, even when they support similar protocols.

Before selecting a gateway, identify the source and destination devices, their communication roles and the operating conditions of the installation.

Typical Applications of Industrial Gateways

• Communication between PLCs: exchanging data between control systems using different protocols.
• Machine integration: connecting machinery to an existing plant network.
• Industrial modernisation: integrating legacy equipment into new automation architectures.
• Instrumentation integration: connecting measurement devices, serial equipment, PLCs and supervisory systems.
• Data exchange between networks: transferring selected information between industrial systems.

Industrial Communication Solutions from Anybus, Helmholz and Red Lion

Anybus Communicator: Industrial Protocol Conversion

Anybus Communicator gateways from HMS Networks enable data exchange between devices using different industrial protocols. They are particularly relevant for machine builders and system integrators connecting different automation platforms. The supported protocols and device roles depend on the model.

Helmholz: Industrial Network Integration

Helmholz offers gateways and couplers for integrating industrial equipment and automation networks, including solutions for connecting CANopen devices to PROFINET control systems. Compatibility and configuration requirements must be checked for each reference.

Red Lion: Protocol Conversion and Data Integration

Red Lion solutions address industrial protocol conversion and data integration. Depending on the selected device, additional functions may include data acquisition, visualisation or communication with supervisory systems.

Protocol Conversion vs. OT Network Segmentation

A protocol gateway exchanges data between compatible systems. An industrial router connects IP networks, while a firewall provides specific functions for controlling authorised traffic between network zones.

Some gateways exchange configured data between separate interfaces without creating a transparent Ethernet bridge. However, protocol conversion alone does not provide a complete OT cybersecurity solution.

Planning for Future Network Expansion

Consider future machine additions, PLC upgrades, changes in process data requirements and maintenance needs. Selecting the appropriate gateway today can simplify subsequent modifications to the installation.
