Web6 mrt. 2024 · PRP main difference compared to HSR: No dependence on network topology (HSR uses a ring) DAN-P 1 DAN-P 2 . PRP frames . PRP does use standard Ethernet frames Each frame has an Redundancy Control Trailer (RCT): 16-bit sequence number 4-bit LAN identifier, 1010 (0xA) for LAN_A and 1011 (0xB) for LAN_B 12-bit frame size . WebHSR nodes have two ports and act as a switch (bridge), which allows arranging them into a ring or meshed structure without dedicated switches. This is in contrast to the companion standard Parallel Redundancy Protocol (IEC 62439-3 Clause 4), with which HSR shares the operating principle.
