This property is updated when performing a new valid reading from a device using its configuration, but this variable's data type (integer, floating point, or text) depends on the OPC UA Driver to which it is linked and on its configuration. This property is only updated this way if the AllowRead property is set to True and when there are no communication errors (in this case only the Quality and TimeStamp properties are updated), but according to the scan time defined in the OPC UA Subscription to which this OPC UA Tag belongs. Another way to use this property is by writing values to a device. Set a new value to the Value property or to any bits Bit00 to Bit31, as long as the AllowWrite property is set to True. This property is also the default property of an OPC UA Tag object. Therefore, a reference by value to an OPC UA Tag does not need to explicit the Value property to access this value. Default value of this property is empty.
