Property Value

The value of this property cannot be null (Nothing in Visual Basic).

Because the AENodeElement has an implicit conversion to OpcLabs.EasyOpc.AlarmsAndEvents.AENodeDescriptor, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned AENodeElement in any place where OpcLabs.EasyOpc.AlarmsAndEvents.AENodeDescriptor is expected as input, and the corresponding OPC A&E node descriptor will be constructed automatically from the OPC A&E node element. When the implicit conversion operators are not supported (such as with Python.NET), you can use the ToAENodeDescriptor static method instead.

Because the OpcLabs.EasyOpc.NodeElement has an implicit conversion to System.String, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned OpcLabs.EasyOpc.NodeElement in any place where System.String is expected as input, and the corresponding OPC node Id (NodeId) will be taken automatically from the OPC node element.
