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)
