The fourth industrial revolution (Industry 4.0) demands that traditional PLC-based automation systems interact seamlessly with autonomous robotic systems. While PLCs offer deterministic microsecond-level control for actuators and sensors, robotic systems require advanced functionalities such as SLAM, path planning, and multi-agent coordination—domains where ROS2 has become the de facto standard.

Use the DDS (Data Distribution Service) backbone of ROS2 to create a unified communication layer across a factory floor. codesys ros2
Combining them tackles a common industrial pain point: low-level hardware integration. A system can be architected where:
As industrial automation continues its trend toward greater flexibility and intelligence, the connection between traditional control systems and robot operating systems will only grow. CODESYS and ROS 2 are at the forefront of this convergence, providing a complete toolchain for building the next generation of smart, connected, and highly capable automation systems.
, the de facto standard for flexible robotics middleware, allows systems to combine robust industrial hardware control with advanced robotic motion planning. 1. Executive Summary This public link is valid for 7 days
Despite the variety of integration methods, a generalized procedure can be applied to most approaches. This walkthrough provides a high-level roadmap for connecting CODESYS and ROS 2.
Step-by-Step Implementation: Building an OPC UA to ROS2 Bridge
By effectively distributing the workload—having CODESYS manage the deterministic, low-level hardware and ROS 2 handle the complex, high-level intelligence—you can build a more reliable, powerful, and efficient robotic system. Can’t copy the link right now
The convergence of Industrial Automation (Operational Technology, or OT) and advanced robotics (Information Technology, or IT) is redefining the manufacturing landscape. At the heart of this revolution is the integration of , the leading IEC 61131-3 development environment for programmable logic controllers (PLCs), with ROS2 (Robot Operating System 2) , the de facto standard framework for open-source robotics research and advanced autonomous systems.
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:
