Abstract :
The IEC62439-3 defines two ways to obtain a high availability automation network: Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy (HSR). In order to do that, those methods include different paths to send information frames from source to destination and add a redundancy field to the frames. Nodes in the network must remember arrived frames so as to manage the duplicated information. In this paper the requirements of memory needed for a hardware implementation are analyzed.
