Assigning synchronization modules to the H-CPUs
In STEP 7 synchronization modules for 10 m length are assigned to the H-CPUs (default
setting).
For the tunnel application, assign synchronization modules for cables up to 10 km in length
(6ES7960-1FB00-0AA5) to the H-CPUs as follows:
1. Change to the device view of an H-CPU.
2. From the hardware catalog, drag and drop the synchronization module with the article
number 6ES7960-1FB00-0AA5 to the interface for a synchronization module of the H-
CPU.
3. The "Replace device- Synchronization module" dialog opens. Confirm the replacement
with "OK".
Figure 2-4 Assigning a synchronization module to the H-CPU
Result: The four synchronization modules for cables up to 10 km in length have been
assigned to the H-CPUs of the redundant system.
