Full title and description

IEC 62541-100:2015 — OPC Unified Architecture - Part 100: Device Interface. This part of the OPC UA family defines the information model for devices and device integration, describing three layered models: the base Device Model (a unified view of devices), the Device Communication Model (adds Network and Connection elements to represent communication topologies) and the Device Integration Host Model (adds host-side elements and rules for managing device integration and reflecting automation-system topology).

Abstract

Specifies the information model associated with devices for OPC UA-based systems. The standard provides object and type definitions, topology and connection constructs, integration-host concepts and mappings/namespaces required for consistent representation of device capabilities and communication topologies in automation and integration platforms. It is intended to enable semantic, vendor-neutral device representations to support interoperability, asset management and system integration.

Scope

This part of IEC 62541 extends the OPC UA information model to cover devices and integration hosts. It defines a base Device Model that provides a uniform device view independent of underlying device protocols, a Device Communication Model to represent networks and connections so that communication topologies can be modeled, and a Device Integration Host Model to represent host-side integration concepts and rules required for managing devices within a system. The scope also includes namespace mappings, profiles and normative annexes that specify required structures for consistent implementation.

Key topics and requirements

• Device Model: standardized object/type definitions to represent devices and common device attributes.
• Device Communication Model: network, connection and topology elements to model communications between devices and hosts.
• Device Integration Host Model: host-side constructs, management elements and rules to support integration and lifecycle handling.
• Profiles and specialization: predefined profiles and guidance for specialized topology elements and AddIn capabilities.
• Namespace and mapping rules: normative annexes for namespace usage and mappings to ensure consistent information-model integration.
• Interoperability requirements: structures intended to support vendor-neutral device representation and system integration.

Typical use and users

Used by device vendors, control-system and automation-product manufacturers, system integrators, middleware and IoT platform developers, and organizations implementing OPC UA-based integration or Industrie 4.0/IoT solutions. Typical applications include representing device capabilities in asset management, modelling communication topologies for integration platforms, and enabling consistent device information exchange between hosts and controllers.

FAQ

Q: What is this standard?

A: IEC 62541-100:2015 is Part 100 of the IEC 62541 OPC Unified Architecture series and defines the Device Interface information model to represent devices, networks and host integration concepts in OPC UA-compliant systems.

Q: What does it cover?

A: It covers a layered device information model (Device Model, Device Communication Model, Device Integration Host Model), associated profiles, namespace/mapping rules and normative annexes needed to model devices and their communication topology for interoperable integration.

Q: Who typically uses it?

A: Device manufacturers, system integrators, automation vendors, OPC Foundation members and platform developers who need a vendor-neutral, semantically consistent device representation in OPC UA environments.

Q: Is it current or superseded?

A: The 2015 edition has been superseded — IEC records show a later edition (IEC 62541-100:2025) and the 2015 edition was scheduled for withdrawal on 17 December 2025. Users should reference the 2025 edition for the latest normative content.

Q: Is it part of a series?

A: Yes — it is part of the IEC 62541 (OPC Unified Architecture) series; implementers should use it together with core parts (Parts 1, 3–7, etc.) for full OPC UA interoperability.

Q: What are the key keywords?

A: OPC UA, Device Interface, Device Model, Communication Model, Integration Host, information model, profiles, namespace mapping, interoperability.
