CODESYS: sovereignty score and 8 European alternatives

CODESYS is a software platform for programming industrial controllers. The CODESYS Development System is an engineering environment that implements the IEC 61131-3 programming languages, and the CODESYS Runtime executes the compiled application on the target device. The runtime is ported to different hardware, so one programming tool serves many controller platforms. Add-ons cover visualisation, motion control, fieldbus communication and safety. Machine builders and automation engineers use it to program PLCs and industrial edge devices.

CODESYS GmbH is headquartered in Kempten, Germany, and is part of the CODESYS Group. The company's own pages name its two founders as its owners and CEOs. The software is installed on engineering computers and on controllers in the customer's plant, so application code and process data stay under the operator's control. For a European organisation, the engineering tools and runtime come from a German company with German owners, while the licence terms determine how far the software can be inspected or modified.

Why digital sovereignty matters with CODESYS

CODESYS is headquartered in DE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

CODESYS runs on infrastructure you choose and control yourself. You decide where the data lives, including fully within the EU if you want — this is not a fixed hosting choice made by the vendor.

CODESYS is closed source, but you run the software yourself on your own infrastructure. The encryption keys and the runtime therefore stay under your own control, though you cannot audit or modify the source code. Ask about export options and open standards to limit software-level lock-in.

What this means for your organisation depends on your whole stack and context. The free assessment weighs CODESYS together with your other vendors and gives a total score, a heatmap and the main risk drivers.
