The information for Maintenance Forecast kept in the controller can be backed up and/or restored.
Caution
The backup and restore operations are performed when the
controller (CPU) is replaced.
When the controller (CPU) is replaced, perform both backup and restore operations in a batch
using the Backup/Restore tool. Also, be sure to back up the information for Maintenance Forecast
before replacement, and restore the backed-up information after replacement.
Perform Backup/Restore between controllers of the same version. If the version is different, an
error might occur.
After the controller (CPU) has been replaced, if the information for Maintenance Forecast is not
restored, or it is restored after a substantial time has elapsed since the time of backup, please note
that the reliability of Maintenance Forecast will be degraded.
