Ring/Network Coupling
The coupling between 2 networks is performed by the main line (solid blue
line). If the main line or one of the adjacent Switches becomes inoperable,
the redundant line (dashed black line) takes over coupling the 2 networks.
The coupling is performed by two Switches.
The Switches send their control packets over a control line (dotted line).
The Switch connected to the main line, and the Switch connected to the
redundant line are partners with regard to the coupling.
 Connect the two partners via their ring ports.
 Select the Redundancy:Ring/Network Coupling dialog.
 Select „Two-Switch coupling with control line" by means of the dialog
button with the same graphic as below

The following settings apply to the switch displayed in blue in the
selected graphic.
 Select the coupling port
With "Coupling port" you specify at which port you are connecting
the network segments:
You will find the port assignment for the redundant coupling in
table 10.
 For a device with DIP switches, you switch the stand-by switch to
OFF or deactivate the DIP switches. Connect the main line to the
coupling port.
