Dialog Box ‘Properties’ - ‘Link to File’

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

Call: Main menu View ‣ Properties, context menu of a GVL.

Import before compile	: With each compile of the project (for example with F11) CODESYS saves a file with extension gvl in the directory defined in Filename.
Export before compile	: An existing export file is read automatically with each project compile. Thus you can import a GVL exported from a different project, for example to setup a communication via network variables.
