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.

Maximum cable length (fiber-optic cable) between the two H-CPUs
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:
Maximum cable lengths between the two H-
CPUs
10 m
10 km (minimum length: 2 m)
40 km (minimum length: 8 km)

Selecting fiber-optic cables

Introduction
You can find an overview of fiber-optic cables, the necessary conditions and technical
specifications in the system manual Industrial Ethernet/PROFINET Passive network compon­
ents (https://support.industry.siemens.com/cs/ww/en/view/84922825).
