Dialog: Properties: Link To File dl-permalink__symbolPermalink

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”

_cds_icon_option_activated_copy.png: 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”

_cds_icon_option_activated_copy.png: 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.
