Editing Interfaces

Editing Interface Elements

When the Interface item of the navigation window is selected, you can use popup dialogs and mouse gestures to edit the interface elements of function block, device, and resource types.

Adding Elements

Elements can added to the interface using the New option of the popup menu which appears by clicking in the body of the interface drawing.

Adapter instances (Plugs and Sockets) can only be added when editing the FB network of a composite FB type.

Editing Elements

An interface element can be edited by double-clicking on its type name, e.g., EVENT or REAL, or via the Edit item of the corresponding pop-up menu.

Adapter instances (Plugs and Sockets) can only be edited in the FB network of a composite FB type.

Moving Elements

An interface element can be moved up or down in its list of elements via the

Up/Down buttons on the toolbar.

Associating Elements

An event can be associated with a variable by using the Alt+Drag gesture between the event's type name, e.g. EVENT, and the variable's type name, e.g., BOOL. Using this gesture where an association already exists will delete the association.

Deleting Elements

An interface element can be deleted by using the Delete item of the pop-up menu obtained by right-clicking on the element's type name. If the element is in use, e.g., in an ECC transition or a function block diagram in the body of a function block, it cannot be deleted.

Adapter instances (Plugs and Sockets) can only be deleted when editing the FB network of a composite FB type.
