IEC 62541-100:2025 (EN-FR)

IEC 62541-100:2025 defines the information model associated with Devices. This document describes three models which build upon each other as follows:
• The (base) Device Model is intended to provide a unified view of devices and their hardware and software parts irrespective of the underlying device protocols.
• The Device Communication Model adds Network and Connection information elements so that communication topologies can be created.
• The Device Integration Host Model finally adds additional elements and rules required for host systems to manage integration for a complete system. It enables reflecting the topology of the automation system with the devices as well as the connecting communication networks.
This document also defines AddIns that can be used for the models in this document but also for models in other information models. They are:
• Locking model – a generic AddIn to control concurrent access,
• Software update model – an AddIn to manage software in a Device.
This second edition cancels and replaces the first edition published in 2015. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a a ComponentType that can be used to model any HW or SW element of a device has been defined and a SoftwareType has been added as subtype of ComponentType;
b the new OPC UA interface concept and defined interfaces for Nameplate, DeviceHealth, and SupportInfo has been added.
c) a new model for Software Update (Firmware Update) has been added;
d) a new entry point for documents where each document is represented by a FileType instance has been specified;
e) a model that provides information about the lifetime, related limits and semantic of the lifetime of things like tools, material or machines has been added.
