Codesys Ros2 Jun 2026

ROS 2 is an open-source software framework developed by the Open Source Robotics Foundation (OSRF). It is designed to simplify the development of complex robot applications by providing a flexible and scalable architecture. ROS 2 offers a wide range of features, including:

More integrated systems where the PLC needs to be a "first-class citizen" in the ROS graph. 3. Shared Memory (The High-Performance Route)

: ROS 2 provides ready-to-use libraries for SLAM, navigation, and computer vision that are not natively available in traditional PLC environments. Developer Accessibility

OPC UA is the industrial standard for data exchange and is highly supported by CODESYS. CODESYS side OPC UA Server directly on the PLC. ROS 2 side : Write a ROS 2 node that acts as an OPC UA client. library for Python nodes or for C++ nodes. 3. Shared Memory (Highest Speed) codesys ros2

The synergy between CODESYS and ROS2 bridges the gap between high-level autonomous decision-making and low-level deterministic hardware execution. While ROS2 excels at complex perception and path planning, CODESYS provides a stable environment for managing industrial fieldbuses like with real-time reliability. 2. Technical Architectures for Integration

Program the control logic in structured text (ST) to handle the incoming/outgoing data 0.5.7 . 4. Example Use Case: Automated Guided Vehicle (AGV) Imagine an AGV in a warehouse.

Integrating with ROS 2 (Robot Operating System 2) represents a powerful convergence of high-speed industrial control and advanced robotic intelligence. While CODESYS provides the deterministic real-time execution required for hardware safety and motion control, ROS 2 offers a vast ecosystem of open-source algorithms for navigation, vision processing, and fleet management. Why Combine CODESYS and ROS 2? ROS 2 is an open-source software framework developed

Using advanced integration methods, such as the CODESYS Communication Packages or containerized microservices, the PLC runtime directly participates in the DDS global data space.

While this method is simple to implement, it does not provide the same level of integration as a dedicated bridge. It works best for non‑real‑time status monitoring or for low‑frequency command signals.

The integration of CoDeSys and ROS 2 can be applied to various industries and applications, including: CODESYS side OPC UA Server directly on the PLC

// Shutdown ROS 2 rclcpp::shutdown();

ROS 2 uses Unix epoch time, whereas PLCs use internal system ticks. If your application relies on precise timestamping (e.g., matching a sensor reading to an exact motor position), implement a time synchronization protocol like PTP (IEEE 1588).

Integrating CODESYS with ROS 2: Bridging Industrial Automation and Robotics

: It allows automation technicians skilled in IEC 61131-3 to manage robot functions without needing deep knowledge of C++ or Python. Comparison: ROS 2 vs. CODESYS Getting Started with ROS 2
