The IEC 61131-3 Development System CODESYS for programming intelligent automation devices is the heart of the engineering platform. The software offers a variety of user-friendly engineering functions to make your development process faster and more efficient.

Based on the  CODESYS Automation Platform, the integrated engineering functions of CODESYS can be seamlessly extended. Using a Software Development Kit (SDK), you can create your own plug-ins under Microsoft .NET and integrate them into the system.

The add-on tools included in the CODESYS Professional Developer Edition help you develop your IEC 61131-3 applications. These tools, which are directly integrated in the controller development system, provide functionalities well-known from high-level language programming.

The CODESYS Application Composer adds a user-friendly application layer to the IEC 61131-3 development system. Using ready made modules, you can compose complete machine or plant applications via drag and drop and then generate structured IEC 61131-3 program code in a click.

Machines and plants with strict redundancy requirements need a redundant controller architecture. With the CODESYS Redundancy Toolkit you can develop CODESYS controllers which run in parallel and supervise each other.
