I have a project with a high ammount of profinet MRP capable devices. There is a real chance for more than 2 of these to fail at the same time. I'm interested in managing more than 1 ring with the same switch in order to save some cabinet space.

For this reason i would like to use only 1 or at least less than 3 switches to manage 6 rings.

I am unable to find clear information if this is possible or not, and which switch could do the job.

Thanks in advance, your help is much appreciated!
