HslDeviceAddressAttribute 类

应用于Hsl组件库读取的动态地址解析，具体用法为创建一个类，创建数据属性，如果这个属性需要绑定PLC的真实数据，就在属性的特性上应用本特性。
Applied to the dynamic address resolution read by the Hsl component library, the specific usage is to create a class and create data attributes. If this attribute needs to be bound to the real data of the PLC, this feature is applied to the characteristics of the attribute.
