9-10 Backup Functions When CJ-series
Units Are Connected
Data in CJ-series Units is covered by the SD Memory Card backup functions and Sysmac Studio Con-
troller backup functions. This section provides precautions for connected CJ-series Units for the data
that is backed up, backup support according to Controller status, and restore conditions.
The present values in memory used for CJ-series Units and the parameters in the CJ-series Units are
backed up. Some of this data is in the CJ-series Unit and some are in the CPU Unit. You do not need to
be aware of where the data is located because the backup, restoration, and verification operations will
automatically process this data.
The following table shows when backup, restore, and verify operations can be performed for CJ-series
Units based on the Controller status.
*1 CJ-series Unit Backup Failed events are recorded in the event log.
*2 CJ-series Unit Restore Operation Failed events are recorded in the event log.
*3 The verification results will show differences.
The following conditions must be met before you can restore the backup data to the CJ-series Units.
• The backup files must contain the CJ-series Unit data.
• The Unit Configuration in the backup file must match the actual Unit Configuration where data is
being restored.
• Each CJ-series Unit must meet the conditions for that Unit. (Refer to the manuals for the CJ-series
Units for the specific conditions for each Unit.)
