OPC UA 節點定義：
1 public interface INode 2 { 3 /// <summary> 4 /// The node identifier. 5 /// </summary> 6 /// <value>The node identifier.</value> 7 ExpandedNodeId NodeId 8 { 9 get; 10 } 11 /// <summary> 12 /// The node class. 13 /// </summary> 14 /// <value>The node class.</value> 15 NodeClass NodeClass 16 { 17 get; 18 } 19 /// <summary> 20 /// The locale independent browse name. 21 /// </summary> 22 /// <value>The name of the browse.</value> 23 QualifiedName BrowseName 24 { 25 get; 26 } 27 /// <summary> 28 /// The localized display name. 29 /// </summary> 30 /// <value>The display name.</value> 31 LocalizedText DisplayName 32 { 33 get; 34 } 35 /// <summary> 36 /// The identifier for the TypeDefinition node. 37 /// </summary> 38 /// <value>The type definition identifier.</value> 39 ExpandedNodeId TypeDefinitionId 40 { 41 get; 42 } 43 }
NodeId 是節點的唯一編號，NodeClass 是節點類型，BrowseName用於瀏覽，DisplayName 是節點的名稱，TypeDefinitionId是類型定義的唯一編號。
