The High-availability Seamless Redundancy protocol (HSR) was designed to meet the highest availability requirements of industrial applications (such as substation automation or motion control) with an Ethernet based communication infrastructure. IEC 61850-90-4 "Network Engineering Guidelines" recommends to use HSR for particular applications.
In the context of the project supported by the Swiss innovation promotion agency CTI, ZHAW is evaluating the feasibility of HSR. Project partners are ABB, Hirschmann, and Siemens. These companies have demonstrated the new solution during the recent Cigré Exhibition in Paris (end of August 2010).
