Properties

DefaultTypeDefinitionId

protected · override

Gets the default identifier which identifies the node that defines the underlying node type from that this OpcInstanceNode has been created.

protected override OpcNodeId DefaultTypeDefinitionId { get; }

Protected Overrides ReadOnly Property DefaultTypeDefinitionId As OpcNodeId
