Parallel redundancy protocol (PRP) solution
HSR applies the PRP principle of parallel operation to a single
ring. For each message sent, the node sends two frames, one
through each port. Both the frames circulate in opposite
directions over the ring. Every node forwards the frames it
receives from one port to another to reach the next node. When
the originating sender node receives the frame it sent, the
sender node discards the frame to avoid loops. The HSR ring
with 615 series relays supports the connection of up to 30
relays. If more than 30 relays are to be connected, it is
recommended to split the network into several rings to
guarantee the performance for real-time applications.
