Codesys Ros2 !!link!! Info

Converting PLC data types (like REAL or INT ) into ROS2 messages ( sensor_msgs/LaserScan , etc.) requires careful serialization.

The divide between traditional industrial automation and high-level robotic intelligence is narrowing. For decades, has been the gold standard for IEC 61131-3 PLC programming, powering the world’s factories with deterministic, stable control. On the other side, the Robot Operating System 2 (ROS2) has emerged as the powerhouse for autonomous navigation, computer vision, and complex path planning. codesys ros2

In a warehouse AMR, CODESYS manages the battery management system (BMS), emergency stops, and low-level motor encoders. Meanwhile, ROS2 runs the navigation stack (Nav2), processing LiDAR data to find the best path around a pallet. Vision-Guided Pick and Place Converting PLC data types (like REAL or INT

Resource-constrained hardware where you want a native-ish ROS2 feel. 2. MQTT or OPC UA Bridges On the other side, the Robot Operating System

ROS2 (unless tuned specifically with a Real-Time Kernel) is not inherently deterministic. Developers must ensure that a delay in a ROS2 node doesn't cause a timeout in the CODESYS task.

Rapid prototyping and systems where millisecond latency isn't the primary concern. 3. Shared Memory (For Single-Platform Systems)

Historically, PLCs handled simple I/O and motion control, while a separate PC handled "smart" tasks like SLAM (Simultaneous Localization and Mapping). Integrating them directly offers several advantages:
