Ports
Ports define connection points that enable interaction between parts. You can specify the flow direction in the properties to determine the flow of the port. You can create ports from System Structure Diagram or from the context menu.
Creating a Port
To create a port:
1. On the System Structure Diagram toolbar, click the Port button.
2. On the diagram, click on the symbol border to add the new port to the symbol.
3. To change or set the direction of the port, in the Properties section, in the Port tab, change the value of Direction to in, out or inout.
The arrow in the Port element set by its Direction property determines the direction of the flow.
When the value is none, the port element has no arrows.
When the value is in, the arrow points inside the element.
When the value is out, the arrow points outside the element.
When the value is inout, a bidirectional arrow is displayed.
