IEC TR 61850-7-500:2017（E）描述了IEC 61850设备和功能的信息模型在变电站自动化系统中的应用，但它也可以用作任何其他应用领域建模的信息输入。特别是，它描述了在智能电子设备（IED）之间使用兼容的逻辑节点名称和数据对象名称进行通信的用例。这包括给定用例的逻辑节点和数据对象之间的关系。如果需要了解用例，还将以信息的方式描述服务的应用。如果不能排除不同的选项，也会提到它们。

IEC TR 61850-7-500:2017(E) describes the use of the information model for devices and functions of IEC 61850 in applications in substation automation systems, but it may also be used as informative input for the modeling of any other application domain. In particular, it describes the use of compatible logical node names and data objects names for communication between Intelligent Electronic Devices (IED) for use cases. This includes the relationship between Logical Nodes and Data Objects for the given use cases. If needed for the understanding of the use cases, the application of services is also described informatively. If different options cannot be excluded they are also mentioned.
