One Ring Topology - ICPDAS RS Series User Manual

Industrial Redundant Ring Switch – RS Series User Manual

One Ring Topology

A ring topology ensures the network having one more chance to keep connection alive
when any connection between 2 switches (nodes) has been broken inside the ring.
When we have formed a ring network, the focal point (master) will choose any one and
only one path as Redundant Path. It is actually inactive when the ring network works
properly. At the moment of any connection failure, the focal point will activates the
Redundant Path and fire alarm to output relay.
