18.39a · Where the target SMETS1 ESME does not support RMSExtremeUnderVoltageThreshold, RMSExtremeOverVoltageThreshold, AverageRMSOverVoltageThreshold, AverageRMSUnderVoltageThreshold, RMSVoltageSagThreshold and RMSVoltageSwellThreshold (with their SMETS1 meaning) at a resolution greater than one Volt, the S1SP shall divide the values in each of the RMSExtremeUnderVoltageThreshold, RMSExtremeOverVoltageThreshold, AverageRMSOverVoltageThreshold, AverageRMSUnderVoltageThreshold, RMSVoltageSagThreshold and RMSVoltageSwellThreshold (with their Message Mapping Catalogue meaning) by 10, round down to the nearest whole number of volts and set the resulting value on the Device.

18.39b · Where the target SMETS1 ESME only supports 60, 300, 600, 900, 1800 and 3600 for AverageRMSVoltageMeasurementPeriod (with its DUIS meaning), the S1SP shall set the value of Average RMS Voltage Measurement Period (with its SMETS1 meaning) to the next greater available measurement period if for AverageRMSVoltageMeasurementPeriod (with its DUIS meaning) is not equal to a supported value or, if the specified period is larger than 3600, set it to 3600.

18.39c · Where the target SMETS1 ESME only supports the setting of AverageRMSOverVoltageThreshold, AverageRMSUnderVoltageThreshold, RMSExtremeOverVoltageThreshold, RMSExtremeUnderVoltageThreshold, RMSVoltageSagThreshold and RMSVoltageSwellThreshold (with their DUIS meanings) to a whole percentage of 230v, then the S1SP shall round down the value in each of the AverageRMSOverVoltageThreshold, AverageRMSUnderVoltageThreshold, RMSExtremeOverVoltageThreshold, RMSExtremeUnderVoltageThreshold, RMSVoltageSagThreshold and RMSVoltageSwellThreshold (with their DUIS meanings) to the nearest whole percentage of 230v and configure the ESME accordingly.

18.39d · Where the target SMETS1 ESME successfully processes the Instructions resulting from this Service Request the device will erase the data used to populate the AvgRMSVoltageProfileDataLog (with its MMC meaning).

18.39e · Where the target SMETS1 ESME only supports 60, 120, 180, 240, 300, 360, 600, 720, 900, 1200 and 1800 for AverageRMSVoltageMeasurementPeriod (with its DUIS meaning), the S1SP shall set the value of Average RMS Voltage Measurement Period (with its SMETS1 meaning) to the next greater available measurement period if for AverageRMSVoltageMeasurementPeriod (with its DUIS meaning) is not equal to a supported value or, if the specified period is larger than 1800, set it to 1800.

18.39f · Where the target SMETS1 ESME only supports the setting of AverageRMSVoltageMeasurementPeriod (with its DUIS meaning) in multiples of 10 seconds, the S1SP shall round up the value in AverageRMSVoltageMeasurementPeriod to the next 10 second increment and configure the ESME accordingly.

18.39g · Where the target SMETS1 ESME supports the setting of AverageRMSOverVoltageThreshold, AverageRMSUnderVoltageThreshold and AverageRMSVoltageMeasurementPeriod (with their DUIS meanings) but does not ever trigger the event when these conditions are detected, then the S1SP will never send the relevant SMETS1 Alert (0x8F40 or 0x8F41).
