Hi..

Could somebody explain about Industry 4.0 ? 

Hello Mazenjer;

1- A very general description from Wikipedia:

Industry 4.0 - Wikipedia

Industry 4.0is the current trend of automation and data exchange in manufacturing technologies. It includes cyber-physical systems, the Internet of things and cloud computing.

2- Presentation on Industry 4.0 from Siemens.

For more documentation from many sources, search on Google.

Hope this helps,
