ValueDeadband

Description

The storage value deadband for the tag. The value deadband is the percentage of the difference between the minimum and maximum engineering units for the tag. Wonderware Historian will not store any tag values that change less than the specified deadband. The value deadband applies to Delta storage only. A value of 0 indicates that Wonderware Historian will not apply a value deadband. This property applies to analog tags. In ClearSCADA the TagStorageType is always set to Forced (never Delta), and therefore this property is not applicable.
