OPC UA for PROFIenergy (see [OPC PE) specifies the structure of energy data provided by a Server as shown in Figure 5. The SerializationScope shown in Figure 5 comprises all MeasurementValueType Variables which are components of the EnergyMeasurementType Objects organized in the “EnergyManagement” Folder Object. The SerializationScope is configured to exclude the constant metadata contained in the Properties belonging to each MeasurementValueType Variable.

Figure 5 – PROFIenergy measurement values

When accessing the Value of the SerializedData Variable, a Client obtains all measurement values of all subordinated “Metering Point” Objects in one single read operation. This supports time consistency of the collection of measurement values the Client gains access to at once.
