Configuration of HRP Rings with Standby Link
Fault tolerance is an important basic requirement for factory and process automation or for energy supply. To increase availability, industrial communication networks are designed with redundant physical connection paths between the network nodes.
One solution approach is the ring topology. It offers a number of advantages:
Fast detection of a network error and reconfiguration of the network.
Can be implemented for small and very large networks.
Cost-effective due to reduced wiring involved.
Clear and simply structured wiring.
Plant can be expanded during operation.
This application example shows the functioning of Siemens’ proprietary ring redundancy protocols called “High Speed Redundancy” (HRP) and “Standby Link”.
HRP is intended to increase the network availability in ring topologies and ensures loop-free communication.
The application example can be additionally expanded by a “Standby Link” intended for redundant linking of two HRP rings.
