This read-write property determines the current tag’s value deadband for Delta 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.CurrentTagValueDeadband = real;

Result = aaHistClientTrend.CurrentTagValueDeadband;

Remarks

The deadband is a percentage of the full scale in Engineering Units. Valid values are 0 (no deadband) to 100. This property is only relevant for Delta retrieval mode. For more information on how this setting works, see Value Deadband (wwValueDeadband).

The default value is 0 (no deadband).
