Adapting Raspberry Pi to Miniaturized Safety Systems for Industry 4.0 Control Applications
Sebastian Domes, Johannes Klos, Ali I. Hayek, Josef Börcsök · 2018
The 4th industrial revolution enables through the networking of automated systems a realization of modular, flexible, economic and networking production processes. Machines and production plants are networked over various communication channels and they organize themselves in an intelligent way. Products are created in an automated way at the request of the customers and tailored to the customers specific needs. Highly networked system structures will evolve including the interference of humans as well as of machines. Apart from IT security functional safety plays an increasingly important role in the networking of humans and machines. In the future, safety functions shall not only control and monitor production processes but they shall be in a position to be maintained and configured in a flexible way by the user. In this paper, a possible implementation is introduced, which is able to connect the functional safety with a compact, cost-effective system that is widely used in industry.
