RetrievalOptionsCycleCount

  • Last UpdatedNov 17, 2021
  • 1 minute read

This read-write property controls the aaHistClientTrend control’s default number of cycles for 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.RetrievalOptionsCycleCount = integer;

Result = aaHistClientTrend.RetrievalOptionsCycleCount;

Remarks

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

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 100.
