Redundant ring structure with SCALANCE XC100-4OBR with TAP function
By using the SCALANCE XC100-4OBR in MRP or HRP rings, ring nodes can be turned on
and off without the redundancy manager reacting to the topology change.
This, for example, allows maintenance to be performed without reconfiguration of the ring.
The communication of the ring nodes continues uninterrupted. This also avoids alarm storms
in the monitored network.
Due to the configurable startup time, end devices that have been turned off are returned to
the network when they are operational and have established the link to the neighboring
network components.
