Redundant controller state synchronization: SchneiderRecent Research Landscape

Latency in failover transitions risks system instability and data loss during hardware transitions. This control system synchronizes execution states and input data between primary and secondary units to ensure deterministic recovery.

What technical problems is Schneider addressing in Redundant controller state synchronization?

Redundant controller state divergence

(3)evidences

Inconsistent logic states and timing mismatches between main and standby CPUs during failover events. Eliminating these discrepancies ensures seamless industrial process continuity without operational errors.

Unsynchronized redundant controller states

(3)evidences

Inconsistent execution states between primary and secondary units during failover events. Eliminating data mismatch ensures continuous process stability and prevents system crashes during transitions.
