CurrentTagUseResolution

  • Last UpdatedNov 17, 2021
  • 1 minute read

This read-write property controls the current tag’s behavior for determining the number of cycles in cycle-based data retrieval. This setting overrides the default setting specified at the application level if the CurrentTagRetrievalStyle property is set to an option other than Style selected at option level.

Syntax

aaHistClientTrend.CurrentTagUseResolution = discrete;

Result = aaHistClientTrend.CurrentTagUseResolution;

Remarks

This property is only relevant if the CurrentTagUseAutoCycles property is set to False.

If this property is set to False, the aaHistClientTrend control uses a fixed number of cycles when retrieving data using cycle-based retrieval modes. To specify the number of cycles, use the CurrentTagCycleCount property.

If it is set to True, the aaHistClientTrend control calculates the number of cycles based on the query duration and a time interval. To specify this interval, use the CurrentTagResolution property.

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

The default value is False.
