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

Introduction
Make the redundancy connections (fiber-optic cables) 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 are allowed.
• The maximum length of the redundancy connections is 10 m / 10 km / 40 km.
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
– Up to 40 km: Sync module 1 GB FO 40 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 497).
– For sync module 1 GB FO 10 m: 1 m, 2 m, 10 m
– For sync module 1 GB FO 10 km: Additional information on fiber-optic cables in longer
– For sync module 1 GB FO 40 km: Additional information on fiber-optic cables in longer
Note
If you use the synchronization modules Sync Module 1 GB FO 40 km (6ES7960-1FE00-0AA5)
in the CPUs 1517H-3 PN or 1518HF-4 PN, then the following maximum ambient
temperatures apply:
• Horizontal mounting position up to 55 °C
• Vertical mounting position up to 35 °C
