Considerations for data backup/restoration
■Use of an SD memory card
• During a data backup or restoration, do not perform the following actions: turning OFF the power, resetting a module, and
inserting or removing an SD memory card.
Otherwise, the data backup or restoration will be interrupted and the data will not be backed up or restored properly.
• Normal backup data cannot be created if the memory size or the number of files exceeds the maximum storage capacity of
an SD memory card during a data backup.
■Operations with a display unit during data backup
If any of the following operations are performed with a display unit during data backup, the operation will be completed
abnormally and the error is displayed on the display unit.
Operation name
Project data batch save/load function
