Codesys 2.3.9 Download Access

  • Allow device driver installation – When prompted, accept the installation of the “CODESYS Gateway” (a service that connects the IDE to runtimes).
  • Finish and restart – Reboot to ensure the Gateway service starts properly.

    • Because V2.3.9 predates Windows 10/11, you may encounter problems. Here are proven solutions:

    | Problem | Solution | |---------|----------| | Installer crashes on Windows 10/11 | Run in compatibility mode: Right-click setup → Properties → Compatibility → Windows 7. | | Gateway service fails to start | Open Services.msc → Find “CODESYS Gateway” → Set to Automatic → Start manually. | | Cannot find target device | Download the specific “.TRG” (target file) from your PLC manufacturer’s site and place it in \CODESYS V2.3\Targets. | | Visualization flickers | Disable hardware acceleration in the IDE settings. | | License lost after reboot | Run as Administrator once to register license dongle emulation (if using demo mode). |

    Pro tip: Many engineers install CODESYS 2.3.9 inside a Windows 7 virtual machine (VMware or VirtualBox). This isolates it from modern OS conflicts and preserves settings for years.

    Crucial Note: As of the last decade, the official CODESYS Store (store.codesys.com) has largely archived or removed public direct links for 2.3.9 in favor of the modern 3.5 releases. Furthermore, Beckhoff (who used TwinCAT 2.x, which is binary compatible) has shifted entirely to TwinCAT 3.

    If you require 2.3.9, you generally have two legitimate sources:

    Because 2.3.9 was often embedded, your PLC manufacturer (e.g., WAGO, Turck, IFM) likely included a branded copy on the original Software CD/DVD that shipped with the controller. These versions are locked to that specific hardware runtime but function identically to the standard IDE.
