In normal operation the ring connection is logically interrupted by monitoring device
(switch configured for Ring Master mode). In case of failure (broken connection or
switch damage) the logically interrupted connection is activated by Ring Master.
A big advantage of this solution is, that no additional central device is necessary for the
redundancy feature. Even if the ring master itself fails, the interruption of the ring
stays at this location.

Ring Mechanism
The from MICROSENS patented protection mechanism supports the fast
reconfiguration of the data transmission in case of failure of one fiber segment. This
function is a fixed feature of the industrial switch. During this operation one switch is
having the manager function, all other switches are normal ring switches.
Each switch is monitoring the status of the connected fiber segment. In case of failure
the connected switch forwards this information to the ring manager. The ring manager
terminates the interruption of the ring immediately. The data is transmitted in all
directions then. This fast signaling a fast failure detection within a few milliseconds
(depending on the ring size).
