Codesys Ros2 Jun 2026

Integrating CODESYS and ROS 2 lets you combine robust industrial control with advanced robotics functionality. The right architecture depends on safety needs, timing constraints, and hardware capabilities — but common themes are clear separation of safety-critical PLC logic from ROS-based autonomy, robust bridging with heartbeats/watchdogs, and careful latency testing. Implement incrementally: begin with telemetry and monitoring, then add constrained command interfaces with strict fail-safes.

There are several ways to bridge CODESYS and ROS2, ranging from rudimentary to deeply integrated.

. While common, these often have higher latency compared to native shared memory implementations. Key Benefits Reliability codesys ros2

A popular entry point for developers is running the runtime. This allows you to turn a standard Raspberry Pi into a PLC, which can then communicate with ROS 2 nodes running on the same board or over a local network. There are several ways to bridge CODESYS and
