Alternatively, you can add a functional block directly from the Program Interface pane following these
steps:

2. The Add Functional Block dialog opens.
3. In the Select Resource Type box, select whether the functional block you are adding is based on a
Standard or User-Defined profile. If you select a User-Defined profile, select the Scope of the
functional profile.
