CODESYS and ROS 2: The Future of Industrial Automation and Mobile Robotics
The industry is seeing a massive shift toward "SoftPLCs" running on Linux. CODESYS has fully embraced this with its runtime for Linux ARM and x64 systems.

We will create a Function Block to handle the MQTT connection. codesys ros2
Which (like EtherCAT or PROFINET) are your motor drives using?
Inside your codesys_bridge package, create a node script ( bridge_node.py ) utilizing the asyncua library to fetch data from CODESYS and publish it onto a ROS2 topic.
There is no native "ROS 2 Driver" built into standard CODESYS. The industry-standard method is the approach. ROS 2 speaks MQTT natively, and CODESYS acts as a client. CODESYS and ROS 2: The Future of Industrial
The "CODESYS ROS 2" integration allows these two giants to communicate seamlessly. This article explores why, how, and where you should implement it.
The synergy between is revolutionizing industrial automation, offering a robust path from prototype to production. By using shared memory bridges, developers can bridge the gap between AI-driven intelligence and hardened, deterministic control.
The integration of CoDeSys and ROS 2 has numerous applications in industrial automation, including: Which (like EtherCAT or PROFINET) are your motor
The key to coupling these systems lies in mapping CODESYS variables to ROS2 topics, services, or actions. The primary mechanism for this is , which is the native middleware for ROS2. A. The CODESYS DDS Solution (Native)
Install the robin package on your Linux machine (Ubuntu/ROS 2).
Rather than writing custom ROS 2 drivers for every fieldbus protocol—CANopen, EtherCAT, Modbus, Ethernet/IP, and others—developers can let CODESYS handle the hardware layer and expose a clean, high‑level interface to ROS 2. This separation of concerns reduces complexity, speeds up development, and improves reliability. In a typical scenario, CODESYS manages all low‑level I/O and fieldbus communication, while ROS 2 focuses on higher‑level motion planning, perception, and overall system coordination.
