View SourceParameters
- historianID Int32
- Historian identifier for which ArchiveDataPoints are to be retrieved.
- startTime DateTime
- Start DateTime (in UTC) for the ArchiveDataPoints to be retrieved.
- endTime DateTime
- End DateTime (in UTC) for the ArchiveDataPoints to be retrieved.
- timeSorted Boolean (Optional)
- Indicates whether the data retrieved from the archive should be time sorted.
Return Value
IEnumerableIDataPointIEnumerableT object containing zero or more
ArchiveDataPoints.

Data is always read from startTime to endTime. If startTime is
greater than endTime, query data will be read from the archive in reverse time order.
