Creating Instances

Finally, we are creating instances in Lesson1NodeManager::Startup() as shown in the following code snippet.

                // Create a Folder for Controllers
                CreateObjectSettings settings = new CreateObjectSettings()
                {
                    ParentNodeId = ObjectIds.ObjectsFolder,
                    ReferenceTypeId = ReferenceTypeIds.Organizes,
                    RequestedNodeId = new NodeId("Controllers", InstanceNamespaceIndex),
                    BrowseName = new QualifiedName("Controllers", InstanceNamespaceIndex),
                    TypeDefinitionId = ObjectTypeIds.FolderType
                };
                ObjectNode controllersNode = CreateObject(Server.DefaultRequestContext, settings);

                // Create an Air Conditioner Controller
                settings = new CreateObjectSettings()
                {
                    ParentNodeId = controllersNode.NodeId,
                    ReferenceTypeId = ReferenceTypeIds.Organizes,
                    RequestedNodeId = new NodeId("AirConditioner1", InstanceNamespaceIndex),
                    BrowseName = new QualifiedName("AirConditioner1", InstanceNamespaceIndex),
                    TypeDefinitionId = new NodeId(yourorganisation.BA.ObjectTypes.AirConditionerControllerType, TypeNamespaceIndex)
                };
                CreateObject(Server.DefaultRequestContext, settings);

                // Create a Furnace Controller
                settings = new CreateObjectSettings()
                {
                    ParentNodeId = controllersNode.NodeId,
                    ReferenceTypeId = ReferenceTypeIds.Organizes,
                    RequestedNodeId = new NodeId("Furnace1", InstanceNamespaceIndex),
                    BrowseName = new QualifiedName("Furnace1", InstanceNamespaceIndex),
                    TypeDefinitionId = new NodeId(yourorganisation.BA.ObjectTypes.FurnaceControllerType, TypeNamespaceIndex)
                };
                CreateObject(Server.DefaultRequestContext, settings);

The following figure shows the result in the server’s address space.
