The PercentDeadBand property determines a minimum variation (dead band) of a Block Element's value, so that this value is updated in E3. This value is specified as a percentage of the difference between DeviceHigh and DeviceLow properties. This property is only used if Block's EnableDeadBand property is set to True. If the PercentDeadBand property is equal to 0 (zero), the Block Element does not have a dead band, and any variation in its value is passed to E3. Otherwise, E3 receives a new value only if its difference, relative to the current value, is larger than the dead band. Default value of this property is 0 (zero).
