Integrating with ROS 2 (Robot Operating System 2) creates a powerful bridge between traditional industrial automation and modern robotic intelligence . This combination allows engineers to leverage the determinism and safety of a PLC (Programmable Logic Controller) alongside the advanced perception, mapping, and navigation capabilities of ROS 2. 1.

This separation of concerns leads to a more robust, maintainable, and efficient system.
On your development computer running Ubuntu and ROS2 (e.g., Jazzy Jalisco or Humble), create a new workspace and package: trigger(CLK:= TRUE); IF trigger
Before any code is written, a common "language" must be defined. This data contract specifies what information will be shared, its format, and the direction of data flow. For example, a simple joint control system might define:
The CODESYS ROS 2 library supports:
A popular entry point for developers is running the runtime. This allows you to turn a standard Raspberry Pi into a PLC, which can then communicate with ROS 2 nodes running on the same board or over a local network.
