代码：

    objects = server.get_objects_node()

    # populating our address space
    sensor1 = objects.add_object('ns=2;s="sens1"', "Sensor 1")
    sens1_current = sensor1.add_variable('ns=2;s="sens1_current"', 'Sensor 1 current', 10)
    sens1_current.set_writable()  # Set MyVariable to be writable by clients
    sens1_status = sensor1.add_variable('ns=2;s="sens1_status"', 'Sensor 1 status', SensorStatusType.Stopped)
    sens1_status.set_writable()

    myobj = objects.add_object(idx, "MyObject")
    myvar = myobj.add_variable(idx, "MyVariable", 6.7)
    myvar.set_writable()  # Set MyVariable to be writable by clients
