Connecting redundancy connections (fiber-optic cables) to S7-1500H

Introduction
The redundancy connections (fiber-optic cables) are connected between the two H-CPUs
using the sockets on the synchronization modules. You need two synchronization modules
per CPU. Connect the synchronization modules in pairs to the fiber-optic cables.
Requirements
● The redundancy connections (fiber-optic cables) must not include any additional media
converters, IO devices or switches. Distribution boxes (Page 124) are allowed.
● The redundancy connections can be a maximum of 10 m/10 km long.
Accessories required
● 4 synchronization modules 2 synchronization modules for each H-CPU
– Up to 10 m: Sync module 1 GB FO 10 m
– Up to 10 km: Sync module 1 GB FO 10 km
● 2 redundancy connections sync cable FO. The redundancy connections can be ordered
in the following lengths. You can find the article numbers in the appendix
Accessories/spare parts (Page 305).
– For sync module 1 GB FO 10 m: 1 m, 2 m, 10 m
– For sync module 1 GB FO 10 km: On request
