4.2 Synchronization modules for S7–400H
Function of the synchronization modules
Synchronization modules are used for communication between two redundant S7-400H CPUs.
You require two synchronization modules per CPU, connected in pairs by fiber-optic cable.
Note
You must use 4 synchronization modules of the same type in an H-system.
The system supports hot-swapping of synchronization modules, and so allows you to influence
the repair response of the fault-tolerant systems and to control the failure of the redundant
connection without stopping the plant.
