IEC 62439 PRP & HSR functional and performance testing for ethernet switches and IEDs
IEC 62439 PRP & HSR functional and performance testing for ethernet switches and IEDS IEC 61850 introduced process bus-based substation communication that can be used for critical real time applications such as protection and circuit breaker tripping. These applications require 100% availability and seamless recovery of the local area network (LAN) even during a single fault! This can only be achieved using dedicated LAN redundancy technologies. The new PRP and HSR protocols (IEC 62439-3) fullfil these requirements.
