Months later, with the system matured, the plant ran like a team moving with purpose. A line change that used to require half a day and two technicians now took minutes: engineers edited a ROS 2 behavior tree, CODESYS loaded the motion parameters, and the translator negotiated the transition. Mobile robots, once cautious, now flowed through aisles with CODESYS-supervised maneuvers and ROS 2-aware intentions—human workers felt safer, and throughput rose.
To appreciate the value of their integration, it is essential to understand the distinct strengths each platform brings to industrial environments. CODESYS (PLC) ROS2 (Robotics Framework) Deterministic machine control, safety, I/O handling Advanced robotics, navigation, computer vision Execution Real-time, cyclic, predictable ( Asynchronous, event-driven, pub/sub architecture Programming IEC 61131-3 (ST, LD, CFC, FBD, IL) C++ and Python Hardware Industrial PLCs, IPCs, embedded controllers Edge computers, GPUs, single-board computers Why Integrate CODESYS with ROS2?
A bridge node written in Python or C++ subscribes to /cmd_vel and packs these floats into a raw UDP packet or an OPC UA write request. Step 2: The CODESYS Side (The Actuator) codesys ros2
This integration allows you to keep (e-stop, light curtains, over-torque protection) while keeping Navigation and Vision in ROS 2 . The safety PLC can monitor and override the ROS 2 commands without a single line of unsafe code in your Python/C++ nodes.
ROBIN supports a wide range of IEC 61131‑3 data types—BOOL, integers of various widths, REAL, LREAL, STRING, as well as arrays and custom structures—and has predefined message definitions for common ROS types. The bridge can be largely automated: the developer defines variables in the CODESYS project, then runs an updater tool that generates the necessary ROS mapping. Months later, with the system matured, the plant
CoDeSys (Controller Development System) is a popular software development environment for industrial automation. It provides a comprehensive set of tools for creating, testing, and deploying control applications on a wide range of industrial controllers. CoDeSys is widely used in various industries, including manufacturing, process control, and building automation.
Bridging the Gap: Integrating CODESYS with ROS 2 for Advanced Industrial Robotics To appreciate the value of their integration, it
. While CODESYS excels at deterministic, real-time control (PLC), ROS 2 provides the "brains" for complex tasks like navigation, computer vision, and AI.
For simpler applications, standard industrial protocols supported by both CODESYS and ROS 2 offer the easiest path.
ROS 2 provides access to millions of lines of open-source code for complex tasks like SLAM (Simultaneous Localization and Mapping) and computer vision.
