Current integration methods focus on bridging data between the ROS2 DDS (Data Distribution Service) layer and the PLC runtime. A. Shared Memory Communication

For low-latency data exchange on a single hardware unit (like a Raspberry Pi running both CODESYS and ROS 2), developers often use shared memory interfaces or MQTT brokers to pass variables between the PLC runtime and ROS nodes.

The official CODESYS ROS 2 library is not the only path. Consider these alternatives for specific use cases: codesys ros2

This architecture represents an optimal separation of concerns: CODESYS manages the time-critical hardware interface, ROS 2 executes the complex processing stack, and the ROBIN bridge ensures efficient, low-latency communication between them.

We can expect to see more commercial off‑the‑shelf bridges, improved real‑time support in ROS 2’s DDS middleware (e.g., zero‑copy shared memory transports), and possibly a native CODESYS‑ROS2 communication library directly from CODESYS Group. Current integration methods focus on bridging data between

is arguably the most robust, open-source solution. Developed in an academic context and applied in industrial projects, ROBIN is an open-source middleware designed specifically for the purpose.

ROS 2 is fantastic for perception, but it is notoriously difficult to certify for functional safety (ISO 13849, IEC 61508). PLC code is not.

CODESYS ROS 2 allows industrial machine builders to finally adopt the rapid development cycle of the ROS ecosystem without sacrificing the deterministic control and safety features of a PLC.

CODESYS and ROS 2 each excel in their respective domains—deterministic control and intelligent robotics. Their integration is not just possible; it is a powerful strategy for building modern, flexible automation systems. Whether you choose a lightweight WebSocket bridge for prototyping, a robust OPC UA interface for IT‑compatible systems, or a high‑performance shared memory bridge like ROBIN for real‑time motion control, the tools are available and ready for industrial use.
