In the world of industrial automation, CODESYS (Controller Development System) stands as the de facto standard for IEC 61131-3 programming. However, moving from the free "demo" mode to a fully functional production environment requires navigating the CODESYS Licensing system. Unlike older software that relied on simple serial keys, modern CODESYS utilizes a container-based licensing model tied to hardware IDs.

Before you type in a single license key, you need to know where the license will live.
