ROS 2 provides the "brains" for complex tasks, such as autonomous path planning using Navigation2 or robotic arm manipulation through MoveIt2 .

CODESYS Control Runtime follows a cyclic executive pattern:

Merging traditional assembly line control (PLC) with robotic vision systems to identify and sort parts on the fly. codesys ros2

Bridging Industrial Automation and Robotics: The Ultimate Guide to CODESYS and ROS2 Integration

No standard solution exists for bidirectional, low-latency communication between a CODESYS PLC and a ROS2 system. ROS 2 provides the "brains" for complex tasks,

A ROS 2 node can be developed as an OPC UA client (often using libraries like asyncua for Python or open62541 for C++) to read and write PLC data.

Before diving into the technical "how," let's establish the business and engineering "why." A ROS 2 node can be developed as

Both are industry standards. Using them together avoids "reinventing the wheel" with custom communication protocols. The Architecture: How It Works

ROS 2 allows your industrial machine to "see" using LiDAR, SLAM (Simultaneous Localization and Mapping), and Neural Networks. Standardization:

The integration is a mature, production-ready bridge that respects the strengths of both worlds. It does not ask a PLC to think like a robot, nor a robot to cycle like a PLC. Instead, it creates a high-bandwidth, low-latency neural link between deterministic control and cognitive autonomy.
