2.2. Standards for Digital Twin Interoperability

As digital twins become more integrated into various industries, the need for standardized communication, data exchange, and system interoperability grows exponentially. To address the challenges discussed in the previous section, several international bodies and organizations have been working on developing standards and protocols that facilitate interoperability between digital twins. In this section, we’ll dive into some of the most prominent standards—such as ISO 23247 and IEEE P2755—and explore how these initiatives are shaping the future of digital twin ecosystems.

2.2.1. ISO 23247: Digital Twin Framework for Manufacturing

ISO (International Organization for Standardization) has been a leading body in establishing global standards, and ISO 23247 specifically focuses on digital twin frameworks in manufacturing environments. The ISO 23247 standard provides guidelines and specifications to help organizations design, develop, and integrate digital twins into their manufacturing operations.

Key Objectives of ISO 23247:

Framework for Digital Twin Integration in Manufacturing

ISO 23247 defines a reference architecture for building digital twins in manufacturing environments. It provides a common framework for connecting digital twins with physical assets, enabling real-time data collection, processing, and analysis.

Standardized Data Exchange

One of the core components of ISO 23247 is the emphasis on standardized data exchange formats. By establishing common protocols for exchanging data between digital twins and other systems, the standard helps ensure that different digital twins in a manufacturing ecosystem can communicate effectively.

Cross-Platform Interoperability

ISO 23247 supports interoperability between digital twins from different vendors or platforms, making it easier for manufacturers to integrate third-party systems without worrying about compatibility issues.

Components of ISO 23247:

Modelling	Specifies how to model physical assets and their digital counterparts.
Communication	Defines communication protocols for connecting physical assets to their digital twins.
Data Management	Establishes best practices for managing, storing, and processing data between systems.
Applications	Provides guidelines for building applications that leverage digital twin data for decision-making, optimization, and monitoring.

2.2.2. IEEE P2755: Standard for Digital Twin Definition and Taxonomy

The Institute of Electrical and Electronics Engineers (IEEE) is another key player in the development of digital twin standards. The IEEE P2755 working group focuses on developing a standardized definition and taxonomy for digital twins. Its aim is to create a universal language that can be used across industries to describe digital twins and their components, thus enhancing interoperability and reducing confusion.

Key Objectives of IEEE P2755:

Unified Definition of Digital Twins

The main goal of IEEE P2755 is to provide a clear and concise definition of what constitutes a digital twin. This is essential, as many organizations and industries have different interpretations of what a digital twin is and how it should function.

Standardized Taxonomy

In addition to defining digital twins, IEEE P2755 aims to establish a standardized taxonomy that classifies different types of digital twins based on their use cases, components, and functions. This taxonomy can help organizations better understand how to design and implement digital twins for specific applications

Interoperability Through Consistency

By providing a consistent definition and classification system, IEEE P2755 enhances the interoperability of digital twins across different industries and platforms. When organizations adhere to the same taxonomy, it becomes easier to integrate digital twins into larger ecosystems.

Components of IEEE P2755:

Definition of Digital Twins	A clear, universally accepted definition of what a digital twin is and what it is not.
Taxonomy of Digital Twins	A classification system for digital twins based on their role (e.g., predictive, operational, or simulation).
Metadata Standards	Guidelines for metadata structures that describe the digital twin and its components, ensuring consistency across platforms.

2.2.3. Open Platform Communications Unified Architecture (OPC UA)

OPC UA is another critical standard that facilitates interoperability between digital twins, particularly in the industrial and manufacturing sectors. OPC UA is a machine-to-machine communication protocol that ensures secure and reliable data exchange between devices and digital twins, regardless of vendor or platform.

Key Objectives of OPC UA:

Unified Communication Protocol

OPC UA provides a standardized communication protocol that enables digital twins to communicate with physical devices, IoT sensors, and other systems, regardless of the vendor or platform.

Security and Scalability

OPC UA is designed with security in mind, ensuring that data exchanged between digital twins and physical systems is encrypted and authenticated. It also supports scalability, allowing systems to grow and incorporate additional devices without significant reconfiguration.

Platform Independence

One of the most important features of OPC UA is its platform independence, allowing it to work across different operating systems, architectures, and vendor ecosystems. This reduces the challenges associated with platform fragmentation.

Components of OPC UA:

Data Modelling	Defines how physical assets and their digital counterparts are modeled for data exchange.
Secure Communication	Provides encryption, authentication, and security protocols to protect data exchange between digital twins and physical devices.
Extensibility	Allows for easy expansion of the system, incorporating new devices and digital twins without requiring a complete overhaul of the existing infrastructure.

2.2.4. Other Emerging Standards and Protocols

While ISO 23247, IEEE P2755, and OPC UA are among the most prominent standards for digital twin interoperability, several other initiatives and protocols are emerging to address specific challenges in various industries.

Key Emerging Standards:

ISO/IEC 30141

This standard provides a reference architecture for IoT systems, which is directly applicable to digital twins that rely on IoT data for real-time monitoring and control.

Asset Administration Shell (AAS)

Developed by Plattform Industrie 4.0, AAS provides a framework for describing digital twins in manufacturing, focusing on asset management and lifecycle integration.

ISO/IEC 27000 Series

These standards focus on information security management and are particularly relevant for ensuring the cybersecurity of digital twins and their data.

2.2.5. The Role of Industry Consortia and Collaborations

In addition to formal standards bodies, several industry consortia and collaborations are playing an important role in shaping the future of digital twin standards and interoperability. These groups work to accelerate the development and adoption of standards across industries.

Key Industry Consortia:

Digital Twin Consortium

This global collaboration brings together industry, government, and academia to accelerate the adoption of digital twin technology and promote interoperability through open standards. The consortium is working to develop best practices, reference architectures, and case studies to help organizations build interoperable digital twins.

Industrial Internet Consortium (IIC)

IIC focuses on advancing the Industrial Internet of Things (IIoT) and has developed frameworks and reference architectures that can be applied to digital twins. The consortium collaborates with other standards bodies, such as ISO and IEEE, to ensure global alignment.
