Add library without placeholder resolution command
Function: The command opens the Find library dialog. In this dialog, you can add library references to the Library Manager in the form of a library and thus integrate them into your application.
Call: Context menu of the References object in the PLC project tree
Prerequisite: The library is installed on the local system in the Library Repository.
Placeholder vs. Library
Through the use of library placeholders the adaptation of the library versions used requires very little effort, thus making the process of engineering projects and libraries very flexible. When a library reference is integrated in a project or in a library project, it is advisable to use a placeholder instead of a library. This means that within the PLC project no specific library is integrated, but a placeholder. A "real" library is then assigned to the placeholder.
For more information see: Library placeholders.
Due to the advantages of a placeholder, the use of the Command Add library is recommended over the Add library without placeholder resolution command.

Find library dialog
The Add library without placeholder resolution command opens a dialog through which a library reference is included in the project as a library and not as a placeholder.
In the row above the library list, you can search for library names or library function blocks by typing a corresponding character string. By double-clicking on a search result or focusing on a search result + [OK], the library associated with the search result is included in the project or in the Library Manager. | |
