Two Ignition Gateways can connect together in a fault-tolerant master/backup configuration, enabling redundancy that protects against server hardware failure. If the master gateway fails, the backup will take over and continue executing. All connected clients will be redirected to the backup machine automatically, and historical data logging will continue with minimal interruption.
After the master is restored, the switch back to the master can be configured to be automatic or require a manual command to be issued.
