The Total Aggregate defined in Table 19 performs the following calculation for each interval:
Total = TimeAverage x ProcessingInterval (seconds)
where: TimeAverage is the result from the TimeAverage Aggregate, using the ProcessingInterval supplied to the Total call.
The resulting units would be normalized to seconds, i.e. [TimeAverage Units] x seconds.
The Aggregate StatusCode will be determined using the StatusCode Calculation (see 5.3).
Note that this calculation always uses a SlopedInterpolation between points; Total2 uses a Stepped Attribute or SlopedInterpolation depending on the value of the Stepped Attribute for the Variable.
