Port usage (ARINC for VxWorks code)
A Port Usage is not an ARINC item, but on the Configuration Diagram's toolbar there is a Port Usage button that creates a UML Association between an Application Part and a Port on a Configuration Diagram. When generated, a Port Usage results in an APEX queuing port or APEX sampling port being generated.
A Port Usage link between an Application Part and a Port results in that Port being generated in the Configuration XML and the application startup code that is generated for the Application Part. For information about how Queuing Ports and Sampling Ports are generated, see the related links below.
To define port usage on a Configuration Diagram: click the Port Usage toolbar button, and the click the following items:
• An Application Part, and then a Source Queuing Port or Source Sampling Port on the Application Part's parent Partition Part.
• A Destination Queuing Port or Destination Sampling Port on a Partition Part, and then an Application Part within that Partition Part.
When shown on a Configuration Diagram a Port Usage's (Association's) notation is as follows:
A Port Usage is a UML Association.
The following sections provide information about how a Port Usage is used in the model.
