description Raspberry Pi + CODESYS Overview

Combining a Raspberry Pi with CODESYS runtime software transforms the single-board computer into a software-based programmable logic controller (soft PLC). CODESYS is an IEC 61131-3 compliant development environment widely used in industrial automation, enabling users to program logic for machinery and processes. This setup allows the Raspberry Pi to interface with industrial sensors and actuators, providing a lower-cost alternative to traditional hardware PLCs. It is well-suited for educational purposes, hobbyists, and small-scale industrial automation testing.

help Raspberry Pi + CODESYS FAQ

What does Raspberry Pi plus CODESYS do?

The combination turns a Raspberry Pi into a software-based programmable logic controller by running the CODESYS runtime. CODESYS provides an IEC 61131-3 development environment for building industrial-control programs.

Can I program the Raspberry Pi CODESYS setup like a PLC?

Yes, CODESYS supports IEC 61131-3 languages commonly used in PLC programming, allowing the Raspberry Pi to run control logic. You still need suitable I/O hardware and a correctly licensed CODESYS Control runtime for the intended deployment.

What can the Raspberry Pi control with CODESYS?

With compatible I/O modules, it can handle tasks such as sensor reading, relay control, sequencing, and small automation systems. The Raspberry Pi's GPIO alone may not provide the isolation, connectors, or industrial robustness required for a production machine.

Is Raspberry Pi plus CODESYS suitable for safety-critical machinery?

A Raspberry Pi running CODESYS is not automatically a certified safety PLC just because it follows IEC 61131-3 programming conventions. Safety-critical equipment requires a validated safety architecture, certified components, and compliance with the applicable industrial standards.
