4.1.5.2 Control Flow

Control elements (such as sensors) that monitor or control behaviour of flow elements (such as valves) use this relationship to indicate control flow logical behaviour.

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 table below shows a recommended list of general usage patterns that users may adopt.
