Standby - Siemens SCALANCE XB-200 Configuration Manual

Changing over the status of the ring ports with the redundancy manager (HRP)
If you configure a redundancy manager, set the status of the ring ports. The first ring port
changes to the "blocking" status and the second ring port to the "forwarding" status. As long
as ring redundancy is enabled, you cannot change the status of these ring ports.
Note
Make sure that you first open the ring so that there are no circulating frames.
Changing ring ports
To change the ring ports, follow the steps below:
1. Open the ring.
2. Select the new ring ports.
3. Change the cable connections.
4. Close the ring.

Standby

Redundant linking of rings
Standby redundancy allows the redundant linking of HRP rings.
To establish a standby connection, configure two neighboring devices within a ring as
standby master or standby slave. The standby master and the standby slave must be
connected via parallel cables to two devices in another ring.
In problem-free operation, messages are exchanged between the two rings via the master. If
the master's line is disturbed, the slave takes over the forwarding of messages between the
two rings.
Enable standby redundancy for both standby partners and select the ports via which the
device is connected to the rings you want to link to.
For the "Standby Connection Name", a name unique within the ring must be assigned for
both partners. This identifies the two modules that belong together as standby partners.
Note
To be able to use the function, HRP must be activated.
The standby manager always requires an activated HRP client or HRP manager.
