IEC 62769-5:2023 is available as IEC 62769-5:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62769-5:2023 defines the FDI？[1] 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 some kind of 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.
