The Energy Measurement Objects provide access to the Energy Measurement values. For each Metering Point one EnergyMeasurementType Object shall exist.
The EnergyMeasurementType contains References to MeasurementValueType Objects.

The PeObjectNumber Variable shall contain the Object number of the related PROFIenergy measurement Object.
The MeasurementValue Variable contains one actual measurement value. For each measurement value of a Metering Point one MeasurementValueType Variable shall exist.
If one of the MeasurementValueType Variables is used as energy counter, the ResetEnergyCounter Method can be used to set the value of this Variable to 0. See section 9.1, ”MeasurementValueType” for further details.
A RepresentedBy Reference may connect the Object to the representing PROFIenergy service access point Object (see PeServiceAccessPointType). The BrowseName of the Reference shall be “PESAP”. If the PESAP is not part of the Information Model, the RepresentedBy Reference in the EnergyMeasurementType Object is omitted.

EnergyMeasurementType Objects should support Interfaces for standardized energy data profiles, so called EnergyProfiles. The supported measurement values demanded by an energy data profile are specified by Interfaces applied to instances of the EnergyMeasurementType.
Table 21 shows the definitions of the Interfaces for the standardized energy data profiles. The EnergyProfiles represent standard Energy Measurement use cases and are therefore the preferred way to represent Energy Measurement data. It is recommended to support at least one of the EnergyProfiles.
