Figure 10: Selecting the redundancy mode
With the “Redundant Ring/Network Coupling” setting, either the main
line or the redundant line is active. Both lines are never active simulta-
neously.
With the “Extended Redundancy” setting, the main line and the
redundant line are simultaneously active if the connection line between
the Switches in the connected network fails (see fig. 11).
During the reconfiguration period, there may be package duplications.
Therefore, only select this setting if your application detects package
duplications.
