In the “Redundancy Mode” frame, select (see fig. 18)
– “Redundant Ring/Network Coupling” or
– “Extended Redundancy”.
Figure 18: 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 redun-
dant line are simultaneously active if the connection line between the
devices in the connected network fails
(see fig. 12) .
During the reconfiguration period, there may be package duplications.
Therefore, only select this setting if your application detects package
duplications.
