IEC62439 PRP Driver - High Availability Industrial Ethernet
In automation networks, availability is a key requirement. Even a short outage can lead to disastrous consequences. The Parallel Redundancy Protocol (PRP) addresses this demanding requirement by communicating via two completely independent networks.
Ethernet gains momentum in the industry and conquers new markets such as automation systems, power plants, traffic infrastructure, and SCADA systems. This increases the requirements on the availability of the network. An industry standard that addresses these requirements is the Parallel Redudancy Protocol (PRP).
PRP is based on a completely redundant network. Devices provide two network interfaces, each connecting to a different network. Both networks are completely independent. This approach provides a bumpless redundancy with off-the shelf networking equipment.
In a PRP network, any single network component may fail without losing a single Ethernet packet!
