It is best to use a virtual machine with Windows 7 (32-bit) to ensure full stability.

CODESYS 2.3.9 is an older version of the popular IEC 61131-3 programming system for industrial controllers. This version was widely used with legacy PLCs from manufacturers like Wago, Beckhoff, Festo, and others.

The need for continues to be high for maintaining established industrial automation infrastructure. By sourcing the software from reputable manufacturers like ifm or Turck, you can ensure that you are working with a stable, functional version of this classic IDE, ensuring your legacy machines continue to run smoothly in 2026.
