Would you like guidance on migrating legacy projects to CODESYS V3 instead, or help finding official support channels for your specific hardware?

Select your . If you do not have hardware connected yet, choose 3S CODESYS SP PLCWinNT V2.4 (this acts as a software PLC on your PC) or choose None to use the internal simulator.

When attempting to go online with a controller, you may encounter communication loss.

| Problem | Likely solution | |--------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | “Installation cannot continue because of missing components” | Run the installer as administrator. Install the Microsoft Visual C++ redistributable packages (especially 2008/2010 versions) before retrying. | | CODESYS crashes when opening a project | Try the project on a clean Windows 7 virtual machine. In Windows 10, set the IDE’s executable to run in Windows 7 compatibility mode. | | The target I need does not appear in the target list | Verify that the TSP is installed correctly using the utility. Restart CODESYS after installing the TSP. | | The online connection to the PLC fails | Check that the communication driver (e.g. CAN driver DLL) is placed in the V2.3 installation directory: C:\Program Files (x86)\3S Software\CODESYS V2.3\ . | | Demo mode resets every hour | This is by design. For continuous operation, purchase a full license for the runtime components. | | Projects with many persistent variables cause timeouts | This is a known limitation in V2.3 (WAT10777). Reconnect several times until the download succeeds, or reduce the number of persistent variables. | Would you like guidance on migrating legacy projects

To download and install CODESYS 2.3.9, follow these steps:

Ensure CODESYS always runs with administrative privileges to read/write to the registry and system directories. Restart your computer to complete the installation of

While modern systems are object-oriented, CODESYS 2.3.9 is structured around traditional PLC programming paradigms.

Unlike open-source software, CODESYS is proprietary software owned by CODESYS Group. The distribution model has changed significantly over the last decade.

Running decade-old automation software on modern operating systems requires specific tweaks. Minimum Requirement Recommended for Windows 10/11 Windows XP / 7 Windows 10 (64-bit) in Compatibility Mode Processor 1 GHz Single-Core 2.4 GHz Multi-Core RAM 4 GB or more Storage 1 GB free space SSD with 5 GB free space Installation Best Practices

If you are planning to use CODESYS (e.g. learning the IEC languages without hardware), no TSP is required – you can simply choose None as the target and the IDE will run in simulation mode.
