Automation systems and integration — Digital twin framework for manufacturing — Part 5: Digital thread for digital twin

This international document establishes a structured framework for implementing digital thread capabilities within manufacturing digital twin environments. It specifically addresses the fifth component of the broader automation and integration series, focusing on the seamless connectivity and data flow required to maintain consistency across the product lifecycle. The content defines the necessary architecture for linking digital representations with physical assets through a unified data pathway. It outlines the technical requirements for data exchange, ensuring that information generated at design stages accurately reflects manufacturing operations and performance feedback. The guidance provided facilitates interoperability between diverse software systems and operational technology platforms. By defining the principles for maintaining data lineage, this specification enables stakeholders to trace information flow from initial concept through production and into service phases. The approach supports the integration of information models with real-time process data, allowing for continuous alignment between the virtual model and its physical counterpart. This specification serves as a technical reference for developing systems that require rigorous data management practices within complex industrial automation scenarios.
