Overview
ISO/IEC 30162:2022 - "Internet of Things (IoT) - Compatibility requirements and model for devices within industrial IoT systems" defines a framework and network models to ensure compatibility and interoperability across Industrial IoT (IIoT) devices, networks and services. The standard addresses how IIoT entities interact across layers (from physical to application), provides guidance for connectivity modelling and testing, and offers best practices for deploying heterogeneous industrial devices and gateways.
Key topics and technical requirements
ISO/IEC 30162:2022 organizes compatibility into functional and non‑functional aspects and specifies requirements for each. Important topics include:
-
Connectivity functional aspects (compatibility requirements per layer):
- Physical, MAC, LLC (link layer)
- Network and transport layers
- Session and presentation layers
- Application layer, measuring & automation aspects
- Semantic interoperability (protocol identification, metadata and data conversion)
-
Connectivity non‑functional aspects:
- Version compatibility and lifecycle management
- Quality of Service (QoS) management and performance expectations
- Security and privacy requirements for IIoT communications
- Compliance and safety considerations
-
Network and device models:
- Direct device connectivity, connectivity through IIoT gateways, and through industrial control systems
- Network model for IIoT compatibility testing and test scenarios
-
Testing and guidance:
- Annexes include a compatibility checklist, load testing scenarios, and mapping of IIoT network structures (including examples such as Semantic Industrial Internet of Things Gateways - SIIG).
Keywords: ISO/IEC 30162:2022, IIoT compatibility, IIoT connectivity, semantic interoperability, IIoT gateways, network model, protocol conversion, QoS, security.
Applications and who uses it
ISO/IEC 30162:2022 is practical for organizations involved in designing, integrating, operating, and certifying industrial IoT systems:
- Device manufacturers - to design IIoT devices that meet compatibility and semantic requirements.
- System integrators and solution providers - to plan heterogeneous deployments, choose gateway architectures, and implement protocol conversion.
- Network architects and operations teams - to model IIoT connectivity, plan QoS, and perform compatibility testing.
- Test labs and certification bodies - to validate interoperability, load performance and compliance.
- Security and safety engineers - to apply the standard’s guidance on security, privacy and safety in IIoT communications.
Practical uses include integrating legacy field protocols (e.g., Modbus, IEC 61850, DNP3), designing gateway translation layers, implementing distributed data management, and executing compatibility test plans before field deployment.
Related standards
ISO/IEC 30162:2022 complements other IIoT and industrial automation standards (referenced within the document), and maps interoperability levels to existing industrial models (e.g., IEC 62264 / Purdue model) for practical deployment planning and testing.
