SCALANCE X-204RNA for HSR and PRP

HSR (High-availability Seamless Redundancy Protocol to IEC 62439‑3)

The SCALANCE X-200RNA (Redundant Network Access) managed Industrial Ethernet network access points with HSR functionality are used to connect up to two non-HSR-enabled terminal devices or network segments to a ring-shaped HSR network structure. They can also be used for simple and redundant transition from HSR to PRP (Parallel Redundancy Protocol) network structures.

• Media redundancy thanks to duplicate transmission of frames in ring-shaped networks
• High plant availability as frames are sent simultaneously over two routes in the ring
• No reconfiguration times of the ring-shaped network are required in the event of an error thanks to duplicate transmission of frames in the ring
• Simple and redundant connection of HSR and PRP network structures

PRP (Parallel Redundancy Protocol, to IEC 62439‑3)

The SCALANCE X-200RNA (Redundant Network Access) managed Industrial Ethernet network access points with PRP functionality are used to connect up to two non-PRP-enabled terminal devices or network segments to parallel networks.

• Media redundancy thanks to duplicate transmission of frames in two parallel, separate networks
• High system availability as frames are sent simultaneously over two separate networks
• Reconfiguration times in a subnetwork do not affect the propagation time because the frames are transmitted via two separate networks (bumpless redundancy)
