RetrievalOptionsResolution

This read-write property controls the aaHistClientTrend control’s default time interval for calculating the number of cycles in cycle-based data retrieval. This setting applies to all tags in a trend whose retrieval style is set to Style selected at option level.

Syntax

aaHistClientTrend.RetrievalOptionsResolution = integer;

Result = aaHistClientTrend.RetrievalOptionsResolution;

Remarks

This property is only relevant if the RetrievalOptionsUseAutoCycles property is set to False, and the RetrievalOptionsUseResolution property is set to True. Also, it may be overridden by a retrieval style setting. For more information, see Working with Retrieval Styles.

The value of this property is a time interval in milliseconds. The aaHistClientTrend control divides the query duration by this interval and uses the result as the number of cycles for the query.

This property is relevant for all retrieval modes except the following: Delta, Full, and Slope.

Valid values: any positive integer or 0. If you specify 0, the cycle count is calculated automatically, just as if the RetrievalOptionsUseAutoCycles property were set to True. The default value is 1000.
