5.3.3.8 Configuration of combined topology with S2 devices
Introduction
The section below shows you the configuration of the S7-1500H redundant system with S2
devices in a combined topology.
Advantages/benefits
•
Within the combined topology, any topology is allowed:
–
Ring topology
–
Line topology
–
Star topology
•
The combined topology can be extended by additional S2 devices.
•
An existing backbone ring can be connected to the S7-1500H redundant system. They
connect the backbone ring and other S2 devices via switches.
Configuration of S7-1500H with S2devices in a combined topology
① CPU 1
② CPU 2
③ Two fiber-optic cables (redundancy connections)
④ Combined topology
⑤ IO device ET 200SP (with system redundancy S2)
