CODESYS GmbH

概要

CODESYS is the leading manufacturer-independent IEC 61131-3 programming system for industrial controllers. Used by hundred thousands of automation engineers worldwide, it provides a comprehensive development environment for programming PLCs, motion controllers, and embedded devices across all major hardware platforms.

The platform supports all IEC 61131-3 programming languages—Structured Text, Ladder Diagram, Function Block Diagram, and Sequential Function Chart—giving engineers the flexibility to choose the best approach for each application. Beyond standard PLC programming, CODESYS offers integrated solutions for motion control, visualization, fieldbus configuration, and safety applications.

With over 500 device manufacturers embedding CODESYS runtime systems in their hardware, engineers benefit from consistent programming across different vendors and devices. This hardware independence reduces training costs and enables code reuse across projects.

Recent innovations include a virtual PLC with safety certification according to IEC 61508 SIL3, and the CODESYS MCP Server, which enables AI assistants to directly interact with automation projects. These tools reflect the platform's evolution toward modern engineering workflows while maintaining the reliability industrial applications demand.
