Overview Of Synchronization Modes - Siemens SICAM AK Manual

Example for AU redundancy with SCA-RS with application-related voting:
Global redundancy switchover: all SEs of an AU are switched active/passive.
Line-by-line redundancy switchover: the SEs of an AU are switched active/passive selectively.
The FUD runs for instance on both C-CPUs of the two AUs. The synchronization mode is High
Speed Link (HSL), if CAEx plus is used on both redundancy BSEs.

Overview of Synchronization Modes

Please note, that the representations are merely examples.
The 3 modes defined apply both for CPU as well as AU redundancy.
