7.50 InletConnectionMeasurementsType ObjectType Definition

The InletConnectionMeasurementsType provides Variables used for measurements performed at a Pump inlet connection and is formally defined in Table 109. For the generation of events, the InletConnectionMeasurementsType has a reference to the 0:LimitAlarmType. The InputNode Property of the Alarm shall contain the NodeId of the Component. Measurements defined in this ObjectType have an additional Subcomponent with the TypeDefinition 0:PropertyType and the BrowseName KindOfQuantity defined in Table 110. In this Variables the measurements can be matched to a physical quantity. To comply with this Companion Specification, the default values for the Property 0:EngineeringUnits and the Property KindOfQuantity provided in Table 111 should be used. The values should be sensible to the use of the application.
