Property Value

The value of this property can be null (Nothing in Visual Basic).

The default value of this property is null.

In order to obtain or modify this parameter, access the OpcLabs.EasyOpc.UA.OperationModel.UAMonitoredItemArguments.MonitoringParameters.

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.

Because the UADataChangeFilter has implicit conversions from System.Double and UADataChangeTrigger, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a double precision floating point number (representing the absolute deadband value), or one of UADataChangeTrigger enumeration members (representing the conditions under which a data change notification should be reported) in place of UADataChangeFilter value when setting this property, and the corresponding OPC UA data change filter will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the UADataChangeFilter Constructor(Double) or UADataChangeFilter Constructor(UADataChangeTrigger) constructor instead.
