Creating Instances

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

Console.WriteLine("Loading the Controller Model.");
ImportUaNodeset(Assembly.GetEntryAssembly(), "buildingautomation.xml");

// New Code Begin
// 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
};
CreateObject(Server.DefaultRequestContext, settings);

// Create an Air Conditioner Controller
settings = new CreateObjectSettings()
{
    ParentNodeId = new NodeId("Controllers", InstanceNamespaceIndex),
    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 = new NodeId("Controllers", InstanceNamespaceIndex),
    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);
// New Code End

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