Overview
IEC PAS 63088:2017 - Smart manufacturing: Reference Architecture Model Industry 4.0 (RAMI4.0) defines a reference architecture for Industry 4.0 and smart manufacturing systems. Published by the IEC as a Publicly Available Specification, RAMI4.0 presents a three‑axis, cubic layer model that describes how physical assets and their virtual representations relate across layers, life cycle & value stream, and hierarchy. The document specifies the structure and function of Industry 4.0 components (including the administration shell) to enable asset description, identification, tracking over their entire life (“vita”), and secure, semantic information exchange.
Key Topics
- RAMI 4.0 cube model: a layered architecture showing technical objects (assets) across the Business, Functional, Information, Communication, Integration and Asset layers.
- Life cycle & value stream axis: describes asset states through types, instances and value‑stream phases (design, production, operation, maintenance, decommissioning).
- Hierarchy axis: aligns assets with organizational and technical hierarchies (field devices → station → enterprise).
- Assets and information world: representation of physical objects by information carriers and digital twins; concepts of unknown, anonymous and individually known assets.
- Industry 4.0 components: properties and requirements such as identifiability, nestability, encapsulability, secure communication, service interfaces and quality of service.
- Administration shell: fundamental structure for the virtual representation of assets, including DF header/body, partial models, views, and management requirements.
- Communication & semantics: secure, I4.0‑compliant communication and semantic information models for interoperability.
- Classification & lifecycle management: asset classification by presentation and communication capability and rules for managing state across the vita.
Applications & Users
Practical uses of IEC PAS 63088:2017 include:
- Designing interoperable digital twins and asset administration systems.
- Guiding manufacturers and system integrators in creating Industry 4.0‑compliant devices and services.
- Enabling software vendors to implement administration shells, semantic models and standard interfaces.
- Helping plant owners, automation engineers and IT architects to manage asset lifecycles, traceability and cross‑system integration.
- Providing a framework for vendors and integrators to ensure secure, standardized data exchange across OT/IT boundaries.
Who benefits: equipment manufacturers, industrial automation vendors, system integrators, enterprise architects, digitalization consultants and standards bodies.
Related standards
IEC PAS 63088:2017 is a pre‑standard PAS from the IEC and complements other IEC/ISO standards and Industry 4.0 initiatives. It serves as a baseline reference for implementing administration shells and interoperable Industry 4.0 components within broader smart manufacturing and automation standardization efforts.
