Figure 6-20 Ring Redundancy WBM menu (if the device is operating as a ring client)
Enable ring redundancy
Here, you can choose whether or not the module is part of a ring.
Redundancy Mode
Here, you can choose the role of the module within a ring.
● Automatic Redundancy Detection
Select this setting to configure the redundant mode automatically.
In "Automatic Redundancy Detection" mode, the IE Switch X-200 automatically detects
whether or not there is a device with the role of "HSR Manager" in the ring. If this is the
case, the device adopts the role of "HSR Client".
If no HSR manager is found, all devices with the "Automatic Redundancy Detection"
setting negotiate among themselves to establish which device adopts the role of "MRP
Manager". The other device automatically set themselves to "MRP Client" mode.
● MRP Client
Here, you can select the "MRP Client" role.
In an MRP ring, at least one device must be set either to the mode "Automatic
Redundancy Detection" or to the mode "MRP Manager (Auto)/Client". You also have the
option of setting the "MRP Client" role for all other devices. If all except one device in the
ring is configured as "MRP Client", this 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.
