In Figure 5.1 : D-Cerno networka graphical
representation of a D-Cerno configuration is
depicted.
At the left side we see a branch configuration
connected to port 1.
At the right a closed loop configuration between port
3 and 4 is shown.
Figure 5.1 : D-Cerno network
Designing a system in a closed loop configuration
provides a redundant system and thus increases the
reliability of the system.
If for some reason a cable or unit gets defective the
system stays operational.
The units have the possibility to detect the flow of
the signal automatically providing a free port
selection. If at some point no signal is provided
anymore, automatically the signal flow will be
reversed. As a result the system configuration stays
operational.
