Once you have set the device to ring topology, the signals to the master are mirrored (echo). This behavior
can result in disturbances such as data collisions in the case of various devices or PC applications.

Off Cascading for star topology, RS232 = Off
Note: This interface remains RS232 = Off in this DIP switch position, even if
you connect a DIGSI cable to the X1 socket.
Signal delay = On (same time behavior as 7XV5450-0BA00/CC and /BB)

Cascading for ring topology, RS232 = On
Signal delay = On (same time behavior as 7XV5450-0BA00/CC and /BB)
Data transfer is the same in both cases (see
Transfer).
Off Cascading for ring topology, RS232 = Off
Note: This interface remains RS232 = Off in this DIP switch position, even if
you connect a DIGSI cable to the X1 socket.
Signal delay = On (same time behavior as 7XV5450-0BA00/CC and /BB)
When the ring topology is activated, the signals are mirrored from R1 to T1
(echo on the master connector).
On Cascading for ring topology, RS232 = Off
For instance, this mode is suitable for time synchronization from SIPROTEC
devices (see
Note: This interface remains RS232 = Off in this DIP switch position, even if
you connect a DIGSI cable.
Signal delay = Off (shorter signal runtime than in 7XV5450-0BA00/CC
and /BB)
When the ring topology is activated, the signals are mirrored from R1 to T1
(echo on the master connector).
