4.5.2.2 Port Connectivity

Ports on distribution elements, such as ducts and airoutlets, or pipes and sanitary elements are connected with each other using the Port Connectivity. The port connection determines the direction of flow between the connected ports belonging to the distribution elements.

The following diagram shows the generic classes and relationships used when applying this concept. In addition, concepts may have particular importance to common or standardised industry practices and scenarios. For these specific usage scenarios, the tables below shows a recommended list of general usage patterns that users may adopt.
