    Network topology with redundancy (PRP) Redundant Network Access (RNA) In Siemens Industry, Redundant Network Access (RNA) stands for devices and software that support the redundancy protocol "Parallel Redundancy Protocol" (PRP). RNA allows the connection of devices to redundant Ethernet network structures.
  • Page 14 Application and functions 1.3 Network topology with redundancy (PRP) Parallel Redundancy Protocol (PRP) The Parallel Redundancy Protocol (PRP) is a redundancy protocol for Ethernet networks. It is specified in IEC 62439-3. The areas of application of PRP are distributed applications with high reliability demands that depend on the high availability of the network.
  • Page 15 Application and functions 1.3 Network topology with redundancy (PRP) Connecting up and cabling Each frame duplicate sent using the PRP mechanisms is given in identifier that specifies whether it is sent via LAN A or LAN B. Note Cabling Make sure that all the PRP ports of the nodes and the SCALANCE X204RNA / RUGGEDCOM RS950G on LAN A and LAN B are connected correctly.
