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, for the data backup, data that was backed up until the data backup
processing was interrupted retains in the SD memory card. As for the data restoration, data that was restored until the data
restoration was interrupted retains in the device supporting iQSS.
• If the memory size or the number of files exceeds the maximum storage capacity of an SD memory card during the data
backup, only the data that has been properly backed up will be stored in the SD memory card.
■Concurrent use of other functions
While any of the following operations or functions are being performed, backup/restoration cannot be performed.
Additionally, the following operations and functions cannot be performed during data backup/restoration.
Operation/Function name
Operation with an engineering tool
Operations with CPU Module Logging
Configuration Tool
Others
When data is backed up or restored during a data logging or the realtime monitor function, the performance of the data
logging or the data sampling for the realtime monitor will be reduced.
Therefore, sampled data may be partially missed and the data missing frequency may be increased.
