If this property is set to True, every time the value in the Value property changes, it updates all bits referring to the Bit00 to Bit31 properties. Likewise, it updates the value in the Value property every time any of the Bit00 to Bit31 properties change their values, and later send it to the device if the OPC Block's AllowWrite property is set to True. Otherwise, if this property is set to False, bits do not change nor lead to any modification. This property can be updated after starting communication. The default value of this property is False.
