Communication networks for industrial applications, like the other ones, use less and less often point-to-point and circuit-commutation technologies, turning to packet commutation. The latter exploits better the bandwidth and reduces costs. However, industrial networks must operate in real time and feature the maximum safety, usually by means of physical redundancy. These requirements avoid using the most widespread packet-commutation, Ethernet, in its conventional version. In order to make Ethernet operate in real time and redundantly, PTP (Precision Time Protocol), PRP (Parallel Redundancy Protocol) and HSR (High-availability Seamless Redundancy) standards have been published. As a matter of fact, the latter has been included in the control and communication structure for supply and distribution grids. It is a key part, in order to provide autonomy for them (smart grids). Nevertheless, the electronic systems suited to these standards are already in the development stage, and not mature yet. SoCe (System-on-Chip engineering) company has designed some PTP, PRP and HSR modules. This project will contribute to implement a prototype and to perform the suitable tests to prove the compatibility among equipments and designs from SoCe and from other companies.
