WARNING
WARNING
• Confirm that stopping PLC operation will not create any problems before restoring data
during PLC operation. If the PLC stops at an unanticipated time, unexpected operation
may occur in the controlled system.
A Downloading Dialog Box will be displayed and the restore status will be displayed in the
7.
Log Display Area.
Note: If the read protection has been set for the connected PLC, the protection must be
cleared before the data can be restored.
Refer to Clearing UM and Task Read Protection, below, for details.
When restoration has been completed, the following Restoration Completed Dialog Box
8.
will be displayed.
• Always turn the power supply to the PLC OFF and then ON after restoring data. If the
power supply is not turned OFF and then ON, memory in the PLC may not be updated to
the restored data, which may cause unexpected operation of the controlled system.
• Forced status can be backed up, but it cannot be restored. If you restored data that
contained forced status, use the CX-Programmer after restoring the data to force-set or
force-reset bits as required. If required bits are not force-set or force-reset, differences
in the forced status in memory may cause unexpected operation of the controlled
system.
