abstract:Parallel Redundancy Protocol (PRP) is a data communication network standardized by the International Electrotechnical Commission as IEC 62439-3 Clause 4. It allows systems to overcome any single network failure without affecting the data transmission.
Tomeet the requirementofswitch-based transmission network for communicationreliability, IEC62439protocol is introduced and PRP (Parallel Redundancy protocol) is adopted.
