    Dialog: Properties: Link To File

    Function: The dialog defines the link of an external file with the contents of the global variable list (GVL). You can either export the GVL to an external file or import it from an external file.

    Call: View → Properties command; context menu of a Global Variable List object

    File name

    Input field of the file path

    Export before compile

    standard icon: Before each compile of the project (for example, with F11), CODESYS saves a file with the gvl extension in the path, which is specified in the File name field.

    Import before compile

    standard icon: The export file which is specified in the File name field is read automatically before each project compile. As a result, you can import a GVL which was exported from another project, for example to set up a communication by means of network variables.
