18.25a · Where the target SMETS1 ESME does not support the Average RMS Over Voltage Counter or Average RMS Under Voltage Counter operational data items (with their SMETS meanings), the S1SP shall omit the AvgRMSOverVoltageCounter and AvgRMSUnderVoltageCounter elements in the SMETS1 Response (with its Message Mapping Catalogue meaning).

18.25b · Where the target SMETS1 GSME does not support the Network Data Log operational data item (with its SMETS meaning), the S1SP shall create a SMETS1 Response indicating failure.

18.25c · Where the target SMETS1 GSME requires an Instruction to begin logging in to the Network Data Log operational data item (with its SMETS meaning), the S1SP shall create a SMETS1 Response indicating failure, since the DCC do not support such Instructions.

18.25d · Where the target SMETS1 ESME does not support the Average RMS Voltage Profile Data Log (with its SMETS1 meaning) to have a period that is the same as the AverageRMSVoltageMeasurementPeriod (with its DUIS meaning) set for calculation of Average RMS Voltage (with its SMETS1 meaning) and the AverageRMSVoltageMeasurementPeriod has not been set to be the same as the Average RMS Voltage Profile Data Log period, the values returned in the Average RMS Voltage Profile Data Log shall be averages for the AverageRMSVoltageMeasurementPeriod calculated at the time of each log entry.

18.25e · Where the target SMETS1 ESME only supports the capture of voltages in the Average RMS Voltage Profile Data Log (with its SMETS1 meaning) with the same Average RMS Voltage Measurement Period (with its SMETS1 meaning), then any existing values, accessible via the AvgRMSVoltageProfileDataLog (with its MMC meaning), will be erased whenever Average RMS Voltage Measurement Period (with its SMETS1 meaning) is changed from its previous value.
