You can adjust the ring sizes in your design so long as no two nodes are more than 15 hops apart.

The TSN network can tolerate a maximum number of 15 hops between any two nodes in the network. When a cable or node fails within a ring, the remaining nodes in the ring reconfigure into two line topologies (daisy chains). In a worst case scenario, a ring of N nodes could reconfigure into a daisy chain of N nodes.
