7.32 MeasurementsType ObjectType Definition
The MeasurementsType provides Objects and Variables used for measurements performed at a Pump. It is illustrated in Figure 18 and formally defined in Table 73. For the generation of events, the MeasurementsType 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 72. 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 73 should be used. The values should be sensible to the use of the application.
