5.4.3.9 Total2
The Total2 Aggregate defined in Table 57 performs the following calculation for each interval:
Total2 = TimeAverage2 x ProcessingInterval of Good data (seconds)
where TimeAverage2 is the result from the TimeAverage2 Aggregate, using the ProcessingInterval supplied to the Total2 call.
The interval of Good data is the sum of all sub-intervals where non-Bad data exists; i.e. if a value was Bad for 1 minute in a 5-minute interval then the interval of Good data would be the 4-minute period.
The resulting units would be normalized to seconds, i.e. [TimeAverage2 Units] x seconds.
The Aggregate StatusCode will be determined using the StatusCode Calculation
(see 5.3).
