8.9.1 Connecting redundancy connections (fiber-optic cables)
8.9.1.1 Synchronization modules for S7-1500H
Introduction
You use the synchronization modules to create two redundancy connections between the
two H-CPUs. You need two identical synchronization modules per CPU which you connect
with fiber-optic cables.

In the S7-1500H redundant system, you need to use four synchronization modules of the
same type. You can order the following types of synchronization modules:
