Within the CODESYS Development System, the next step is to implement the logic for receiving data from and sending data to ROS 2. In a CODESYS program, a programmer might create a reference to a publisher object and a Twist message object, which is then populated with data and published.

// Create a ROS 2 publisher auto publisher = node->create_publisher<std_msgs::msg::String>("co_de_sys_topic", 10);

Use CODESYS for safety-critical logic, I/O handling, and motion control, while using ROS2 for complex decision-making, mapping, navigation (SLAM), and computer vision.

Map IEC 61131 types (e.g., REAL , BOOL ) correctly to ROS2 message types (e.g., float32 , bool ) to avoid serialization errors. codesys ros2

In CODESYS, you set up a communication task to receive these velocity vectors. If using UDP, you can utilize the SysSocket or CAA Ethernet libraries to open a listening port.

The integration of (the industry-leading, hardware-independent PLC programming system) and ROS 2 (the modern standard for robotics) provides a powerful hybrid architecture. This article explores how to connect these two worlds, enabling robust, high-performance industrial robotics. 1. Why Integrate CODESYS and ROS 2?

provide a direct ROS node and CODESYS library to exchange data via shared memory. This is ideal for high-speed control (up to 1000 Hz) where both ROS 2 and the soft PLC run on the same embedded hardware, such as a Raspberry Pi ctrlX CORE Standard Industrial Protocols : You can connect them using common protocols like Modbus TCP EtherNet/IP

Highly secure, standard-compliant, easy to configure in CODESYS, and requires no custom PLC-side communication code. Within the CODESYS Development System, the next step

For years, these two ecosystems existed in isolation. Bridging them required complex, custom-built communication bridges that introduced latency and vulnerabilities. Today, integrating —the leading hardware-independent IEC 61131-3 development system—with ROS 2 has emerged as a premier architecture for next-generation smart factories. Why Connect CODESYS with ROS 2?

The integration of CODESYS and ROS 2 enables sophisticated automation systems across various industries. The table below outlines some key application areas.

Native integration, high performance, no intermediate bridging software required.

If you are running on the same industrial PC as your ROS2 Humble or Iron distribution, shared memory is the fastest route.

It natively supports industrial fieldbuses like EtherCAT, PROFINET, and EtherNet/IP to control motors, pneumatics, and I/O.
