ROS2, built on top of DDS (Data Distribution Service), is designed for high-throughput data flow. It creates a peer-to-peer network of nodes where a lidar sensor might publish a point cloud that is consumed by a navigation stack. It is highly flexible but introduces complexities regarding latency and determinism.
Some advanced implementations involve integrating a DDS client directly within the CODESYS environment, allowing the PLC to appear as a native participant in the ROS 2 network. 3. Key Use Cases codesys ros2
ROS 2 (Robot Operating System 2) is an open-source software framework for building robot applications. It provides a flexible and modular architecture for developing complex robot behaviors, allowing developers to focus on high-level tasks rather than low-level details. ROS 2 is designed to be highly scalable, secure, and reliable, making it suitable for a broad range of applications, from robotics and autonomous systems to industrial automation and IoT.

Developers can map IEC variables to MQTT or other standard protocols, which can then be ingested by a ROS2 node. This abstracts away the complex socket programming, allowing the PLC engineer to "tag" a variable in the development environment and have it instantly available to the network.
: Simple to implement using standard CODESYS libraries; works on almost any modern PLC.
