Minimum retrieval - initial and final values

For analog tags, the minimum value of the tag in the cycle leading up to the query start time is returned with its timestamp changed to the query start time. If there is no point exactly at the "phantom" cycle start time, the point leading up to the phantom cycle is also considered for the minimum calculation.(No adjustments are made to the quality of the initial point even though the timestamp may have been altered.) Apart from the initial value, all points returned are delta points. (For more information on initial values, see Delta retrieval - initial values.)
If a point occurs exactly on the query end time, that point will be returned with the partial cycle bit, 4096, set in quality detail. If there is more than one such point, only the first point will be returned.
