| Component | Description | |---------------------------|-------------| | | The full programming system for PLCs. | | CoDeSys SP RTE | A soft‑PLC for Windows with hard real‑time properties (demo version runs 1 hour, restartable). | | CoDeSys HMI | A Windows runtime for visualizations created in CoDeSys (also 1‑hour demo mode). | | CoDeSys ENI Server | An engineering server supporting multi‑user operation and version control (limited to a local database in demo mode). | | CoDeSys SoftMotion | Integrated motion control libraries (fully functional for 30 days in demo mode). |
It is best to use a virtual machine with Windows 7 (32-bit) to ensure full stability.
CoDeSys relies heavily on external libraries for advanced tasks like Modbus communication, PID control, or string handling. When opening a legacy project from a backup, you will often see a "Missing Library" error. You must locate these .lib files from the original machine builder or the component vendor and place them into the CoDeSys Library directory on your hard drive.

Select the default, standard installation to ensure all necessary IEC libraries are included.
Generally stable. Most engineers run CoDeSys 2.3.9 on Windows 10 without major issues, though you may need to enable administrator privileges. | | CoDeSys ENI Server | An engineering
Whether you are maintaining a legacy plant, learning the ropes of IEC 61131-3, or working with specific hardware that hasn't made the jump to Version 3.5, CODESYS 2.3.x remains a cornerstone of the industry. Why the Demand for Version 2.3.9?
If you are programming a specific controller (such as a WAGO 750 series or an IFM mobile controller), it is often better to download the customized CODESYS 2.3.9 installer directly from that manufacturer's support portal. These OEM bundles come pre-packaged with the necessary Target Files (device descriptions) and libraries specific to their hardware lines.
