Bridging Real-Time Control and Robotic Middleware: An Architectural Framework for CODESYS-ROS2 Integration

Abstract The convergence of classical Programmable Logic Controller (PLC) ecosystems and modern robotic software frameworks is a critical challenge in Industry 4.0. CODESYS, a dominant IEC 61131-3 development environment, excels at hard real-time control and fieldbus management (EtherCAT, CANopen). The Robot Operating System 2 (ROS2), built on Data Distribution Service (DDS), provides a flexible, distributed middleware for perception, planning, and collaboration. This paper proposes a formal architecture for integrating CODESYS runtime with ROS2. We analyze communication patterns, data representation mapping, real-time constraints, and security implications. A reference implementation using ROS2-native client libraries for CODESYS is presented, alongside performance benchmarks comparing native DDS versus OPC UA gateway approaches. codesys ros2

Traditionally, industrial automation and robotics operated in separate silos. Bridging them allows developers to leverage the best of both worlds: This paper proposes a formal architecture for integrating
