Force device to Standby Master
If you select this check box, the device is configured as a standby master regardless of its
MAC address.
– If this check box is not selected for either of the devices for which the standby master
is enabled, then assuming that no error has occurred, the device with the higher MAC
address adopts the role of standby master.
– If the option is selected for both devices or if the "Force device to Standby Master"
property is supported by only one device, the standby master is also selected based
on the MAC address.
This type of assignment is important in particular when a device is replaced. Depending
on the MAC addresses, the previous device with the slave function can take over the role
of the standby master.
Note
If two devices are linked by the standby function, the "Standby" function must be enabled
on
both devices.

Select the port to be standby port. The link to the other ring is via the standby port.
The standby port is involved in the redirection of data traffic. In there are no problems,
only the standby port of the master is enabled and handles the data traffic into the
connected HRP ring or HRP bus.
If the master or the Ethernet connection (link) of one of the standby ports of the master
fails, the standby port of the master will be disabled and the standby port of the slave
enabled. As a result, a functioning Ethernet connection to the connected network
segment (HRP ring or HRP linear bus) is restored.
