The factory of the future is digital and networked. The Industrial Internet of Things (IIoT) and Industry 4.0 are a further optimization of processes and faster production cycles for production companies and critical infrastructures. Industry 4.0 refers to the current trend of automation and data communication in manufacturing technologies. It includes cyber-physical systems, the Internet of Things, cloud computing and cognitive computing. The basic principle of Industry 4.0 is that by connecting machines, work pieces and systems; businesses are creating intelligent networks along the entire value chain that can control each other autonomously. In an Industry 4.0 factory, components and systems are able to gain self-awareness and become self-predictive, which will provide management with more insight on the status of the factory.
