Protect MySupervision Type Example

保护 MySupervision 类型示例

The following example will show the impact that the Hidden and Protected attributes may have on a self-defined type called MySupervision_type, which is part of the library MyTankLib.

下面的例子将展示一个叫做 MySupervision_type的自定义类型的隐藏和保护属性的效果，该类型是MyTankLib库一部分。

A Simplified Library Solution

简化库解决方案

The library MyTankLib contains three different types, MyMotor_type, MySupervision_type and MyTank_type. The Motor10 object is located inside MyTank_type, see Figure 59. As you can see, Motor10 has inherited its definition from the type MyMotor_type.

库 MyTankLib 包含三个不同的类型，MyMotor_type, MySupervision_type 和 MyTank_type. Motor 10对象位于 MyTank_type内部，见图59. 如你所见，Motor 10从MyMotor_type类型继承了其定义。

Protect MySupervision Using the Hidden Attribute

使用隐藏属性保护MySupervision

MyMotor_type contains a SpeedSupervision object (and a Feedback error object). The SpeedSupervision object is of the type MySupervision_type. Both MyMotor_type and the MyTank_type therefore depend on MySupervision_type. To hide the code inside the MySupervision_type, we must set the attribute Hidden on MySupervision_type, see Figure 60.

MyMotor_type包含SpeedSupervision 对象（和反馈错误对象）。SpeedSupervision 对象是MySupervision_type类型。MyMotor_type 和MyTank_type 依赖于MySupervision_type。也要隐藏MySupervision_type内部代码，必须设置MySupervision_type隐藏属性，见图60.

Figure 60. MySupervision_type is not shown in Plant Explorer after setting the hidden attribute. (Left) Project Explorer with SpeedSupervision still visible. (Right) Object Type Structure where both MySupervision_type and SpeedSupervision are hidden.

图 60. 设置隐藏属性后，在工厂浏览器中不显示MySupervision_type 。（左）项目视图中SpeedSupervision 依然显示。（右）对象类型结构中MySupervision_type 和 SpeedSupervision都隐藏。

After Hidden is set on the Supervision type, it disappears from both the Project Explorer and the Plant Explorer. However, MySupervision type can still be traced via calls from the SpeedSupervision object inside the motor type to our hidden supervision type in Project Explorer, see Figure 61.

在Supervision 设置隐藏之后，它从项目资源管理器和工厂资源管理器中消失了。然而，MySupervision 类型仍可以通过调用从 motor 类型内部的 SpeedSupervision 对象到 Project Explorer 中的隐藏监督类型来跟踪，参见图 61。

Figure 61. The hidden MySupervision type can still be traced via the SpeedSupervision object in both the motor type and the motor object.

图 61. 隐藏的 MySupervision 类型仍可通过电机类型和电机对象中的 SpeedSupervision 对象进行跟踪
