IEC 62439-3 Clause 4 (Parallel Redundancy Protocol, or PRP), and IEC 62439-3 Clause 5 (High-availability Seamless Redundancy, or HSR), are standardized redundancy protocols for industrial automation networks that require zero recovery time. PRP/HSR products are suitable for electrical substation automation and mission-critical applications that cannot tolerate any system downtime.
