The PercentDeadBand property determines the minimum variation of a Tag's value (dead band), so that this value can be updated on E3. This value is specified as a percentage of the difference between DeviceHigh and DeviceLow properties. This property is only used if Tag's EnableDeadBand property is set to True. If Tag's PercentDeadBand property is set to 0 (zero), the Tag has no dead band, and any variation in its value is sent to E3. Otherwise, E3 only receives a new value whose difference, relative to E3's current value, is larger than dead band. Default value of this property is 0 (zero).
