Hello, I'm having some troubles configuring a multi MRP network with S7-1500R/H CPUs. According to Chapter 9.4 of the S7-1500 manual (https://cache.industry.siemens.com/dl/files/833/109754833/att\_965668/v3/s71500rh\_manual\_en-US\_en-US.pdf), the CPUs must be configured as Manager (auto) within the ring where they are located (ports P1 and P2 of the Scalance switch). All other devices are configured as Clients. I observed that this configuration works properly (at least based on the settings). However, when I add a second ring (ports P3 and P4), the "Media Redundancy Role" of MRP instance 1 turns red and produces the error: The selected multiple MRP role "Client" in instance "1" from "SCALANCE interface_1" is not supported in multi-MRP operation. This contradicts what I read in the manual, and I also cannot set both CPUs as "Clients".
