Part 1: The Concept of Digital Twin

Concept and Core Elements of Digital Twins:
- A concept that encompasses PLM (Product Lifecycle Management) from product design through to operation and disposal.
- Digital twins include digital simulation and interact with the Digital Thread.
- Core components are services, data, and models.
- Various industries have attempted to apply this, and to prevent confusion, standards have emerged, such as ISO 62264.
- Once established, it provides explosive improvements in productivity, but because the initial costs for implementation are also very high, in Korea there's only been a tendency for adoption centred around large corporations.
- The conceptual aspects of digital twins explained in the book weren't much different from what I'd anticipated. Whilst digital twins can be applied to various industries, manufacturing is intuitive for understanding application examples, so this book's explanations are centred around manufacturing as well.

There was a lot to study today.
I gained a better understanding of the need for standards.
- If everyone develops software separately, you'd have to create new interfaces every time you want to connect different software together or modify them slightly for use, which would reduce reusability and productivity.
- So it makes sense that we need to establish unified rules.

1. Industrial Automation Communication and Connectivity Standards

Commonalities:

All provide physical communication layers for connecting factory floor equipment via networks

Differences

Vary in speed, complexity, and scope (AS-i for simple sensors, Profinet for complex control)

Core Purpose:

Standards / Protocols
