Codesys Ros2 100%

For a standard configuration, developers often use OPC UA or Modbus TCP. Since CODESYS includes built-in OPC UA servers, a ROS 2 node running an OPC UA client wrapper can read and write PLC tags.

1. OPC UA (Open Platform Communications Unified Architecture)

To understand the value of this hybrid architecture, it is essential to look at what each platform does best. codesys ros2

Runs navigation algorithms (SLAM) to determine the best path, running on a ROS-enabled computer.

A shared memory area allows the PLC and ROS 2 to share a memory region at high speed. Advantage: Minimal latency for tight control loops. For a standard configuration, developers often use OPC

Success bred ambition. They taught ROS 2 to understand recipes: sequences that required sub-millimeter placement and human-safe approaches. ROS 2 planned a trajectory; CODESYS executed the motor profiles with hard real-time precision. For complex inspection runs, drones fed point clouds into ROS 2, which framed possible repairs and dispatched the nearest mobile platform. CODESYS ensured every actuator stayed inside certified constraints; ROS 2 negotiated exception cases and re-planned on the fly. Together, they became more resilient than either could be alone.

The lines between traditional industrial automation (Operational Technology) and advanced robotics (Information Technology) are blurring. For decades, Programmable Logic Controllers (PLCs) running CODESYS have mastered deterministic, real-time control of factory machines. Meanwhile, the Robot Operating System 2 (ROS2) has become the standard for intelligent, high-level robotic tasks, navigation, and perception. Advantage: Minimal latency for tight control loops

Micro-ROS allows ROS2 nodes to run on microcontrollers and RTOS-based systems. For CODESYS users, this often involves using a .

The worlds of industrial automation and advanced robotics are rapidly converging. Historically, industrial automation relied on Programmable Logic Controllers (PLCs) running deterministic, robust, and safe control loops. Meanwhile, advanced robotics—especially Autonomous Mobile Robots (AMRs) and Automated Guided Vehicles (AGVs)—developed within the open-source, highly flexible ecosystem of the Robot Operating System (ROS and now ROS 2).

There are several proven methods to bridge CODESYS and ROS 2. The choice depends on factors like performance needs, hardware constraints, and the nature of the project.
