Configuration in WBM

Role
The choice of role depends on the following use cases:
● You want to use MRP in a ring topology only with Siemens devices:
– For at least one device in the ring select "Automatic Redundancy Detection" or "MRP
– For all other devices in the ring select "MRP Client" or "Automatic Redundancy
● You want to use MRP in a ring topology that also includes non-Siemens devices:
– For exactly one device in the ring select the role "MRP Auto Manager".
– For all other devices in the ring topology, select the role of "MRP client".
Note
The use of "Automatic Redundancy Detection" is not possible when using non-Siemens
devices.
● You configure the devices in an MRP ring topology partly with WBM and partly with STEP
7:
– With the devices you configure using WBM, select "MRP Client" for all devices.
– With the devices that you configure using STEP 7, select precisely one device as
Note
If a device is assigned the role of "Manager" with STEP 7, all other devices in the ring must
be assigned the "MRP Client" role. If there is a device with the "Manager" role and a device
with the "Manager (Auto)"/"MRP Auto-Manager" in a ring, this can lead to circulating frames
and therefore to failure of the network.
