Energy Measurement functionality allows the retrieval of energy related measurement values. Possible Energy Measurement values offered are energy counters, current power consumption, active and reactive power, frequency, voltage, current, information about maximum and minimum values of the former, and more. Furthermore, the Energy Measurement is not limited to electrical energy. In addition, different Metering Points of a device can be distinguished.

In general, the number and type of Energy Measurement values provided are vendor specific. For simplification and standardization, specific EnergyProfile types are defined which comprise a predefined set of measurement values together with a guaranteed measurement accuracy. However, when proxying the PROFIenergy Profile, additional measurement values are already defined (See [PE CAP] for details).

Energy Measurement is made available for OPC UA Clients with the ObjectTypes defined in chapter 8.2Energy Measurement”.
