With this command you can merge objects (POUs, data types, visualizations, and resources) as well as links to libraries from other projects into your project.
When the command has been given, first the standard dialog box for opening files appears. When you have chosen a file there, a dialog box appears in which you can choose the desired object. The selection takes place as described with 'Project' 'Document'.
If an object with the same name already exists in the project, then the name of the new object receives the addition of an underline and a digit ("_1", "_2" ...).
