Description
Backup communication is communication between the primary and backup processors. Without backup communication, the backup processor receives only input and peer-to-peer data.
Since the primary and backup processors may have started at different times and are not synchronized, the data table values may be different in each processor. You can reduce these differences by transferring internal storage points via backup communication.
