WebSep 1, 2024 · HSR is designed to work in a ring topology. The same standard defines PRP used in star topologies. HSR defines a ring with traffic in opposite directions. Port-A sends traffic counter clockwise in the ring and Port-B sends traffic clockwise in the ring. WebHigh-availability Seamless Redundancy ( HSR) is a network protocol for Ethernet that provides seamless failover against failure of any single network component. PRP and HSR are independent of the application-protocol and can be used by most Industrial Ethernet protocols in the IEC 61784 suite.

WebJul 17, 2024 · PRP Uses a Redundancy Control Trailer (RCT) the format of which is similar to HSR Tag. This is used for implementing redundancy. RCT consists of 6 bytes similar to HSR tag and contain following fields:- - 16-bit sequence number (SeqNr); - 4-bit LAN identifier (LanId); - 12 bit frame size (LSDUsize); - 16-bit suffix (PRPsuffix). WebThe major difference between HSR and PRP is that HSR networks are configured as a ring, then frames are sent both directions around the ring by all nodes.
