Precautions
The following describes the precautions for the restoration function.
Prohibited operation during execution of the restoration processing
Do not perform the following operations during execution of the restoration processing.
• Attaching or detaching the SD memory card
• Powering off or resetting the CPU module
The above mentioned operations leave the data in the CPU module in an incomplete state which is in the middle of the
restoration processing. Do not run the CPU module with this incomplete state. Doing so may cause an unintended operation.
Always execute restoration again.
Suspending the restoration processing
The following operation can suspend a restoration processing.
• Setting the SD memory card forced disable
Suspension during a restoration leaves the data in the CPU module in an incomplete state which is in the middle of the
restoration processing. Do not run the CPU module with this incomplete state. Doing so may cause an unintended operation.
Always execute restoration again.
Automatic restoration using SD955 and restoration using CPU module auto exchange cannot be suspended.
Types of CPU modules that execute restoration
Make sure CPU module model being restored is the same model as the backup source CPU module. Restoration of different
models is not possible.
When error is occurring in CPU module
Restoration may not be possible if a parameter error is occurring in the CPU module at the restoration destination.
Changing the operating status during execution of restoration
During execution of the restoration processing, the CPU module remains in the STOP state even if the RUN/STOP/RESET
switch is changed from the STOP to RUN position or the remote RUN or the remote PAUSE is executed. The following
operation will take place if the CPU module operation status is changed while executing restoration.
• If the restoration target data is all target data or all target data excluding device/label data, the specified operation status will
not be entered when restoration is completed.
• If performing restoration without parameter change (parameter of backup date and restoration destination CPU module are
same), the specified operation status will be entered.
• The specified operation status is entered after restoration is completed only when the restoration target data is device/label
data.
• If performing automatic restoration or restoration with CPU module auto exchange, the specified operation status will be
entered when restoration is completed.
