TagRatchet Function

Returns the largest instance of the selected MeterTagId over the specified DateRange or
time span and IntervalInMonths ending with the optional EndDate argument. The
EndDate argument is a String type. If the EndDate is not specified, the IntervalInMonths
ends on the current date and overlaps the specified DateRange or time span. Usage:

Result = TagRatchet(MeterTagId, [EndDate,] IntervalInMonths,
DateRange.enumValue)

Result = Tagratchet(MeterTagId, [EndDate,] IntervalInMonths,
months, days, hours, minutes)

TagLowest Function

Returns the smallest instance of the selected MeterTagId over the specified DateRange or
time span. Usage:

Result = TagLowest(MeterTagId, DateRange.enumValue)

Result = TagLowest(MeterTagId, months, days, hours, minutes)

TagNLowest Function

Returns a Double array of N elements containing the N smallest instances of the selected
MeterTagId over the specified DateRange or time span. Usage:

Result = TagNLowest(MeterTagId, N, DateRange.enumValue)

Result = TagNLowest(MeterTagId, N, months, days, hours, minutes)

TagLowestTimestamp Function

Returns a DateTime structure containing the UTC time stamp of the smallest instance of
the selected MeterTagId over the specified DateRange or time span. Usage:

Result = TagLowestTimestamp(MeterTagId, DateRange.enumValue)

Result = TagLowestTimestamp(MeterTagId, months, days, hours,
minutes)

TagNLowestTimestamps Function

Returns a DateTime array of N elements containing the UTC time stamps of the N
smallest instances of the selected MeterTagId over the specified DateRange or time span.
Usage:

Result = TagNLowestTimestamps(MeterTagId, DateRange.enumValue)

Result = TagNLowestTimestamps(MeterTagId, months, days, hours,
minutes)

TagSum Function

Returns the arithmetic sum of the selected MeterTagId over the specified DateRange or
time span. The TagSum function is usually used with non-consumption values such as
hourly production. Usage:

Result = TagSum(MeterTagId, DateRange.enumValue)

Result = TagSum(MeterTagId, months, days, hours, minutes)
