Using the Library Navigator

• A ">" prefix indicates that the element is located in the Web library; for example, the ASEL_UINT FB type in the figure below.
• A "+" prefix indicates that the element is located in the Web library and also has a copy (whose contents may be different from the Web library element) in the local file system; for example, the X2Y2 FB type in the figure below.
• An element name with no prefix exists only in the local file system; for example, the NewBasic FB type in the figure below.

Icon	Element Type
	Data Type
	FB (Function Block) Type
	Adapter Type
	IEC 61131-3 Function Type
	Resource Type
	Device Type
	(Network) Segment Type
	System Configuration

• Selection - i.e., clicking on an element, for instance, the X2Y2 FB type in the example below - will cause the selection of the corresponding tab (if it exists) in the Editor area to the right of the Library Navigator.
  • Selection of a tab in the Editor area will also select the corresponding element in the Library Navigator ("two-way synchronization") if an element with the tab name is currently in the library.
• Double-clicking an element in the Library Navigator will open it for editing in a tab of the Editor area.
  • If the element is already open in a tab, this will just select the existing tab.
• Deletion of an element in the local library can be done from its pop-up menu in the Library Navigator.
  • An element in the Web library cannot be deleted, but its local copy may. This will cause the element's prefix in the Library Navigator to change from "+" to ">"
  • The menu will not pop up unless the element is in the local library and is not open in a tab of the Editor area.
• Drag and Drop (DnD) can be used to add a graphical element to a diagram in the Editor area by dragging from its type element in the Library Navigator and dropping on the desired location in the diagram.
  • Dropping of a graphical element is only allowed when it is consistent with the IEC 61499 information model; for example, an instance of a Device type can be dropped into a System diagram, but not into a diagram of the contents of a Resource.
  • When feasible, dropping the element on the diagram will open a dialog in which you can specify a name and comment for the dropped element.
  • DnD can also be used to change the type of a graphical element by dropping on the instance name that appears above the block outline (the name acts as a "handle" for manipulating the block). This operation is only allowed when:
    • both the instance name and body of the element are the same (non-white) color, indicating that the element is editable; and
    • the new type is the same kind of Library Element as the old type, e.g., a Function Block type cannot be dropped on a Resource; and
    • the interface of the new type is a proper superset of the interface of the old type, i.e., it contains at least all of the interface declarations of the old type.
