CODESYS software development suite

CODESYS is a leading industrial software suite used for developing controller applications according to the international industrial standard IEC 61131-3. Originally developed in Germany, it has become the global standard for PLC programming, used by hundreds of hardware manufacturers to power their automation devices.

The software is developed and maintained by the CODESYS Group, which remains an independent software company headquartered in Kempten, Germany. It provides a complete development environment, including editors for various programming languages, a fieldbus configurator, and a visualization tool, making it a cornerstone of modern Industry 4.0 and industrial IoT implementations.
