Redundancy can be implemented at different levels of your system, depending on the reliability requirements of your project. The following types of redundancy are available:
Multiple data paths to a device can be configured within CitectSCADA. Therefore, if the primary path becomes unavailable, data can still be monitored over the secondary path.
Primary and Standby Alarms, Reports, and Trends Servers can be configured so that if a primary server becomes unavailable to process a client's request, the request can be channelled to a standby server for processing.
To avoid service interruptions when the primary network isn't operating, a redundant LAN can be implemented that will provide an alternative path to a server if necessary.
