5.3.3.10 Configuration without additional devices
Introduction
The section below shows you the configuration of the S7-1500H redundant system without
additional devices (IOdevices, switches, Y-link) at the PROFINET interface X1 P1R/X1 P2R of
the H-CPUs.
Advantages/benefits
The configuration is suitable for all applications that do not require any further devices at the
PROFINET interface X1 P1R/X1 P2R of the H-CPUs.
Example: In a plant, the S7-1500H redundant system communicates with third-party devices
