S7-1500H configuration with S2 devices and backbone ring
① CPU 1
② CPU 2
③ Two fiber-optic cables (redundancy connections)
④ Switch
⑤ Backbone ring (existing combined topology)
⑥ IO device ET 200SP (with system redundancy S2)

5.3.3.9 Configuration of combined topology with R1 devices
Introduction
The section below shows you the configuration of the S7-1500H redundant system with R1
devices in a combined topology.
Advantages/benefits
•
Within the combined topology, any topology is allowed:
–
Ring topology
–
Line topology
–
Star topology
•
The combined topologies can be extended by additional R1 devices.
•
Two existing backbone rings can be connected to the S7-1500H redundant system as
separate networks. They connect backbone rings and other R1 devices via switches.
