What is Industry 4.0?
Industry 4.0 refers to the fourth industrial revolution, in which production processes are digitalised and connected through smart technologies. The aim is to make factories more flexible, efficient, autonomous and data-driven.
The term was introduced in 2011 in Germany as part of a high-tech strategy for industry.
🔄 The four industrial revolutions in summary
| Phase | Characteristic |
|---|---|
| Industry 1.0 (c. 1780) | Mechanisation through steam power |
| Industry 2.0 (c. 1870) | Mass production via electricity and assembly lines |
| Industry 3.0 (c. 1970) | Automation with electronics, PLCs, IT |
| Industry 4.0 (from c. 2011) | Cyber-Physical Systems, IoT, data analytics and AI |
⚙️ Key technologies in Industry 4.0
- Industrial Internet of Things (Industrial Internet of Things): connected machines and Sensors
- Cyber-Physical Systems (CPS): physical systems with digital intelligence
- Big Data & analytics: collecting and interpreting real-time data
- Cloud computing: scalable data storage and processing power
- Artificial intelligence (AI): self-learning algorithms for optimisation
- Digital Twins: virtual replicas of physical processes or systems
- Additive Manufacturing (such as 3D printing)
- Augmented Reality (AR) for maintenance and training
🧱 Typical characteristics of an Industry 4.0 factory
- Self-directing: machines communicate and take decisions
- Real-time connected: continuous data exchange between systems
- Flexible: customised production and small-batch runs are possible
- Data-driven: decisions based on up-to-date information
🏭 Application examples
- Predictive Maintenance
- Smart production lines that automatically adjust to product variations
- Real-time quality control using Vision systems
- Full traceability via Sensors and MES/ERP integration
🔐 Linkage between IT and OT
Industry 4.0 requires close integration between:
- OT (Operational Technology): machines, Sensors, PLCs
- IT (Information Technology): databases, analytics, cloud platforms
Cybersecurity also plays a major role here (including via standards such as IEC 62443).
📌 In summary
Industry 4.0 is the digital transformation of production environments, where automation, data and smart technologies come together to make factories more intelligent and efficient.
