Hello everybody, we are from NR electric. We prefer to demonstrate PRP/HSR. Although it had been shown in Paris in 2012, but this time we care more about its usage in processing bus. IEC61850-90-4 has depicted more network technique in details, particularly for high reliable and time-critical usage. PTP over HSR/PRP maybe too early for mass protection. But the interoperability of processing bus maybe attractive.
