Redundancy Mode
In the "Redundancy Mode" drop-down list, choose how the role of a device will be specified
within the ring:
● Disabled
● Automatic Redundancy Detection (ARD)
Select this setting to configure the redundant mode automatically.
In "Automatic Redundancy Detection" mode, the IE Switch automatically detects whether
or not there is a device with the role of "HRP Manager" in the ring. If this is the case, the
device adopts the role of "HRP Client".
If no HRP manager is found, all devices with the "Automatic Redundancy Detection" or
"MRP Auto Manager" setting negotiate among themselves to establish which device
adopts the role of "MRP Manager". The device with the lowest MAC address will always
become "MRP Manager". The other device automatically set themselves to "MRP Client"
mode.
● MRP Auto Manager
Devices with the setting "Automatic Redundancy Manager" or "MRP Auto Manager"
negotiate among themselves which device will adopt the "MRP Manager" role. The
device with the lowest MAC address will always become "MRP Manager". In contrast to
the setting "Automatic Redundancy Detection", the devices are not capable of detecting
whether or not an HRP manager is in the ring. This means that they never adopt the role
of "HRP client".
● MRP Client
Here, you can select the "MRP Client" role.
In a ring in which the devices are configured with MRP, at least one device must be set to
one of the modes "Automatic Redundancy Detection" or "MRP Auto Manager". You also
have the option of setting the "MRP Client" role for all other devices. If all devices except
one are configured as "MRP Client", this one device automatically adopts the role of
"MRP Manager".
Select "MRP Client" mode if you want to operate the device along with components that
do not originate from Siemens in the ring.
● HRP Client
Here, you can select the role "HRP Client".
● HRP Manager
Here, you can select the role "HRP Manager". When you configure an HRP ring, one
device must be set as HRP manager. All other devices must be configured as HRP
clients.
