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: Menu bar: “View Properties”; context menu of an object of type “Global Variable List”

“File name”	Input field of the file path
“Export before compile ”	: Before each compile of the project (for example with [F11]), CODESYS saves a file with the extension `‎gvl‎` in the path, which is specified in the “File name” field.
“Import before compile ”	: The export file which is specified in the “File name” field is read automatically before each project compile. Therefore you can import a GVL which was exported from another project, for example to set up a communication by means of network variables.
