Ring/Network Coupling
Figure 26: One-Switch coupling: Selecting the redundancy mode
With the "Redundant Ring/Network Coupling" setting, either the
main line or the redundant line is active. The lines are never both active
at the same time.
With the "Extended Redundancy" setting, the main line and the
redundant line are simultaneously active if the connection line between
the devices in the connected (i.e., remote) network becomes inoperable
(see figure 27). During the reconfiguration period, packet duplications
may occur. Therefore, select this setting only if your application detects
package duplications.
