A CODESYS V2.3 Gateway Server project can be converted into a CODESYS V3 project only if the CODESYS V2.3 Converter package is installed in CODESYS V3. The package is available in the CODESYS Store.

Requirement: CODESYS is started (or a project is already open). You should be aware of the restrictions described below the following instructions.

  1. Click “File  Open Project”.

  2. In the “Open Project” dialog, click any CODESYS V2.3 Gateway Server project or project archive in the file system. For searching, you can set the file filter on the bottom right corner of the dialog.

    If another project is still open, CODESYS instructs you to close it accordingly. After that the CODESYS V2.3 Gateway Server converter starts automatically.

  3. The V2.3 converter checks that the project can be compiled without errors. If so, then it processes the project automatically.

  4. NOTE:

    If the project contains visualization objects with placeholder variables that the converter cannot resolve, the respective visualizations are shown as a group in place of the visualization references.

  5. Device conversion: When a device (target system) is referenced in the project to be opened and no conversion rules are defined for the device, then the “Device Conversion” dialog opens. Specify here whether and how the converter should replace the previous device reference with a current one.

    For replacement, the converter added the new device in the place of the old one in the device tree of the converted project.

  6. Library conversion: if a library, for which no conversion rule has so far been defined, is referenced in the project to be opened, then the “Conversion of Library Reference” dialog opens. Specify here whether and how the converter should replace the existing library reference with a current one.

    If you select a library for which the project information is missing, then the “Enter Project Information” dialog opens in order to specify this information.

    The converter loads the adapted project. Note: The recently defined library references can be found in the Global Library Manager located in the POUs view.
