An “External File” is any file that you add to the project in the “POUs” view or “Devices” view. Click “Project Add Object” to open the “Add External File” dialog and define how the file belongs to the project.
An external file which was inserted in the “POUs” view is never downloaded to the controller.
An external file which was added in the “Devices” view is always downloaded to the controller when an online change or a download is performed due to an IEC code change.
When an external file is downloaded to the controller, it is not updated in the project.
