Line topology configuration with R1 devices and switches

Introduction
The section below shows you the configuration of the S7-1500H redundant system with R1
devices and switches in a line topology.
Advantages/benefits
• You can use switches to extend the line topology with lower-level R1 devices by two
PROFINET rings.
• In the configuration variant, one PROFINET ring is connected to each switch. Each
PROFINET ring is located in its own MRP domain.
• This configuration variant enables modular commissioning of the redundant system.
Example: Distributed I/O systems are already mounted and wired. The H-CPUs are each
connected to the distributed I/O systems via the PROFINET interface X1.
