The Mapping Definition window shows the current mapping between attributes of the adjacent IN- and OUT-structures. To open the Mapping Definition window, right-click the connecting link and select Mappings from the pop-up menu. Selecting Display Structure and values from the list box in the toolbar displays the fields, as well as the current values.
This view shows the current content of the port connecting
to the link. If the port contains no data, only the port structure
is shown in this window. You can populate data in a port by stepping
through your project until you reach the port.
