Summary0005141: Wrong statusCode in Sample Historian_3 for TimeAverage
Description

Specification Part 13 - Annex A - A.4 TimeAverage:

Table for Historian_3:
12:01:30.000 90 UncertainDataSubNormal, Calculated, Partial
Think the statuscode is wrong, it should be UncertainDataSubNormal, Calculated, not includes the Partial bit

The last data point for Historian3 is at 1:30, with a value of 90, Good, which suggests that the interval is incomplete, and thus the partial bit should be set.

However, TimeAverage always uses sloped interpolation, and allows for sloped extrapolation, so an end bound value can be calculated.
Also, there is no special case for EndOfData, extrapolation is allowed.

The partial bit could be an interpretation of the spec. Does finding an endbound value mean that the interval is complete?

The original test tool, and the current test implementation both have a status of UncertainDataSubNormal, Calculated.

Fixed in 1.05.2. The last stored data point is the first and only data point in the second last interval therefor it has the partial bit set. The last interval is fully after the last data point and follows a partial interval meaning the final interval is set to Bad_NoData (see 5.3.3.2).

Agreed to changes in 1.05 Draft. Needs Errata for 1.04 and 1.03, but holding off until all Part 13 issues are fixed.

Agreed to 1.04.11 Errata, but still needs 1.03 Errata.
