The following schematic shows a possible topology for devices in a ring with MRP.
Figure 4-19 Example of a ring topology with the MRP media redundancy protocol
The following rules apply to a ring topology with media redundancy using MRP:
● All the devices connected within the ring topology are members of the same redundancy
domain.
● One device in the ring is acting as redundancy manager.
● All other devices in the ring are redundancy clients.
Non MRP-compliant devices can be connected to the ring via a SCALANCE X switch or via
a PC with a CP 1616.
If you configure MRP in a ring, you must not use the "prioritized startup" function in
PROFINET applications on the devices involved.
If you want to use the "prioritized startup" function, then disable MRP in the configuration.
