标准范围

IEC 62769-5:20 21作为IEC 62769-5:20 21 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 62769-5:20 21定义了FDI信息模型。信息模型的主要任务之一是反映自动化系统的拓扑结构。因此，它表示自动化系统的设备以及连接通信网络，包括它们的属性、关系和可以在它们上执行的操作。FDI服务器地址空间中的类型构成了一个目录，该目录是从FDI包构建的。FDI信息模型的基本类型在OPC UA for Devices（IEC 62541-100）中有很好的定义。FDI信息模型为一些特殊情况指定了扩展，并解释了如何使用这些类型以及如何从DevicePackages的元素构建内容。总体FDI架构如图1所示。本文档范围内的体系结构组件已在此图示中突出显示。

IEC 62769-5:2021 is available as IEC 62769-5:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62769-5:2021 defines the FDI Information Model. One of the main tasks of the Information Model is to reflect the topology of the automation system. Therefore, it represents the devices of the automation system as well as the connecting communication networks including their properties, relationships, and the operations that can be performed on them. The types in the AddressSpace of the FDI Server constitute a catalogue, which is built from FDI Packages. The fundamental types for the FDI Information Model are well defined in OPC UA for Devices (IEC 62541-100). The FDI Information Model specifies extensions for a few special cases and otherwise explains how these types are used and how the contents are built from elements of DevicePackages. The overall FDI architecture is illustrated in Figure 1. The architectural components that are within the scope of this document have been highlighted in this illustration.
