Parallel Redundancy Protocol (PRP) is a network protocol standard for Ethernet that provides seamless failover against failure of any network component. This redundancy is invisible to the application. PRP nodes have two ports and are attached to two separated networks of …

High-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.

What are HSR&PRP? • High Availability Seamless Redundancy (HSR) standardized in IEC62439-3 Chapter 5 • Parallel Redundancy Protocol (PRP) standardized in IEC62439-3 Chapter 4 • Redundancy protocols for automation networks • They describe how network redundancy can be achieved and how the redundancy can be monitored

Aug 1, 2018 · If are looking into network technologies for power substations, or industrial automation you may run across HSR and/or PRP. So here is the five-minute version of what these things are.

ORing Industrial Networking has launched a new-generation HSR/PRP module that can be applied to existing rackmount modular Ethernet switches: the RGS-P9000/PR9000 Series, achieving zero packet loss and zero-time recovery.

HSR (IEC 62439-3 Clause 5) ap-plies the PRP principle to rings and to rings of rings to achieve cost-effective redundancy. To this effect, each device incorporates a switch element that for-wards frames from port to port.

Jan 18, 2025 · In this blog we will look at two industrial-ethernet protocols: PRP (Parallel Redundancy Protocol) and HSR (High-availability Seamless Redundancy). Specified in IEC 62439-3, PRP and HSR are designed to provide zero-recovery-time redundancy to prevent downtime in mission-critical networks.

HSR (High-availability Seamless Redundancy) and PRP (Parellel Redundancy Protocol) are protocols supporting redundant network connections defined by IEC 62439-3. Both operate by using two ethernet ports together, and duplicating every frame to be sent over both ports, so if one connection fails, the transmission succeeds.

HSR/PRP is Ethernet based communication technology commonly deployed in smart grid substation for low cost, easy to maintain and interoperable common network infrastructure with built-in redundancy. This application report presents the overview of HSR/PRP technology followed by HSR/PRP solutions on Sitara devices.

HSR (High-avail­abil­i­ty Seam­less Redun­dan­cy) is a redun­dan­cy pro­to­col for Eth­er­net net­works requir­ing short reac­tion times and high avail­abil­i­ty, as for exam­ple pro­tec­tion sys­tems at elec­tri­cal substations.
