Ensure the OPC UA server is enabled in the PLC communication settings. Step 2: Create the ROS2 Bridge Node
Here is a practical workflow to establish communication between a CODESYS controller and a ROS2 node using OPC UA. Step 1: Configure the CODESYS OPC UA Server Open your CODESYS project. Add a object to your application tree. codesys ros2
Excels in deterministic, real-time control of I/O, safety, motion, and industrial protocols (EtherCAT, PROFINET). It is fast, robust, and reliable.

The convergence of industrial automation and advanced robotics is reshaping the manufacturing landscape. Historically, industrial automation relied on Programmable Logic Controllers (PLCs) executing deterministic, rigid logic via languages like IEC 61131-3. In contrast, advanced robotics evolved around the Robot Operating System (ROS and now ROS 2), an open-source framework designed for complex, non-deterministic tasks like computer vision, motion planning, and autonomous navigation. It is fast, robust, and reliable

This is the most performant method, typically used when the CODESYS SoftPLC (e.g., CODESYS Control for Linux ) and ROS2 run on the same hardware platform.
