The Library is located on the Solution Explorer. This is where you place all of the Ladder Functions (UDFBs), C Functions, HMI screens, and Web Pages that you want to be available for use throughout all of your UniLogic Projects.

To place UDFBs and HMI screens in the Library, either right-click them in the Solution Explorer and add them to the Library, or place them in the appropriate Library folder, right-click Library, and select Refresh.
