5.4.6 Resetting the LioN-R modules to factory settings
The LioN-P /-R modules are reset to the factory settings in Step 7 via the
menu item
Target device > Edit accessible devices
. After you search
through the subscribers accessible online and select the LioN-P/-R module,
this module is reset to the factory settings by clicking the "Reset to factory
settings" button.
5.5 Media Redundancy Protocol (MRP)
Redundant PROFINET communication can be implemented with the LioN-P
modules via a ring topology without the use of additional switches. A MRP
redundancy manager terminates the ring, detects individual failures, and
transmits the data packets on the redundant path in case of error.
The following conditions must be met to use MRP:

All devices must support MRP.

MRP must be enabled on all devices.

Connections to the devices are only possible via the ring ports. A mesh
topology is not permissible.
