Property Value

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

Remarks

In OPC UA, a Property is a type of Variable. Another type of Variable is DataVariable.

Browsing with the parameters returns nodes with OpcLabs.EasyOpc.UA.AddressSpace.UANodeClass.Variable node class, referenced by forward references with reference type Id OpcLabs.EasyOpc.UA.AddressSpace.Standard.UAReferenceTypeIds.HasProperty (i=46) or its subtype.

In OPC UA, references are used to relate nodes to each other. Each reference has a type, and the reference types form an inheritance hierarchy. Browsing and querying is used to retrieve the references from the address space. For visual illustration of the inheritance hierarchy of standard reference types, see Standard ReferenceType Hierarchy in the OPC UA specification (Part 3).

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