Structure of the S7-1500H redundant system

Configuration
The S7-1500H redundant system comprises the following components:
● Two H-CPUs
● Two SIMATIC memory cards
● Four synchronization modules (two synchronization modules in each H-CPU)
● Two redundancy connections (two duplex fiber-optic cables)
● IO devices
● Load power supply (optional)
● System power supply (optional)
The S7-1500H redundant system should be installed either on one shared mounting rail or
on two separate mounting rails. You connect the two CPUs with fiber-optic cables to two
synchronization modules in each CPU. You set up the PROFINET ring with the PROFINET
interfaces X1 P1 R and X1 P2 R of the CPUs.
