IEC 62439-3:2012 cancels and replaces the first edition published in2010. These standard versions are also referred to as IEC 62439-3Edition 1 and IEC 62439-3 Edition 2. The protection relay supportsIEC 62439-3:2012 and it is not compatible with IEC 62439-3:2010.PRPEach PRP node, called a doubly attached node with PRP (DAN), is attached to twoindependent LANs operated in parallel. These parallel networks in PRP are calledLAN A and LAN B. The networks are completely separated to ensure failureindependence, and they can have different topologies. Both networks operate inparallel, thus providing zero-time recovery and continuous checking of redundancy toavoid communication failures. Non-PRP nodes, called single attached nodes (SANs),are either attached to one network only (and can therefore communicate only withDANs and SANs attached to the same network), or are attached through a redundancybox, a device that behaves like a DAN.Ethernet switchIEC 61850 PRPEthernet switchREF615 REF620 RET620 REM620 REF615SCADACOM600GUID-334D26B1-C3BD-47B6-BD9D-2301190A5E9D V1 ENFigure 7: PRP solutionIn case a laptop or a PC workstation is connected as a non-PRP node to one of the PRPnetworks, LAN A or LAN B, it is recommended to use a redundancy box device or anEthernet switch with similar functionality between the PRP network and SAN toremove additional PRP information from the Ethernet frames. In some cases, defaultPC workstation adapters are not able to handle the maximum-length Ethernet frameswith the PRP trailer.There are different alternative ways to connect a laptop or a workstation as SAN to aPRP network.1MRS756378 S Section 2REF615 overviewREF615 33Application Manual
