(6) Functions that cannot be performed during restoration
Functions that cannot be performed during restoration are the same as the ones that cannot be performed during
backup. (
(7) Precautions
(a) Do not perform the following operations during restoration.
• Mounting/removal of a memory card
• Power-off of the CPU module
• Reset
(b) Even if mounting a memory card storing backup data file to the Universal model
QCPU having the serial number (first five digits) is "10101" or earlier and powering
off and then on the CPU module or reset the CPU module, the system ignores the
backup data file and starts operation (a diagnostic error is not detected).
(c) Do not use a memory card where the boot file setting parameter is stored. If used,
data in the memory card are overwritten by the boot file setting even restoration is
performed.
(d) If restoration is started from GX Developer, the following functions stop (do not
resume the operations even after the restoration).
• Refresh of network modules
• Data link transfer
• Auto refresh of intelligent function modules
• Auto refresh of CPU shared memory

Table6.60 Error when automatic restoration is not normally completedÅ@
The CPU module where data are restored is different model with the one where the backup
source data are stored.
• Backup data file is corrupt (The contents of backup data file do not match with the check
code).
• Reading of backup data from a memory card was not normally completed.
• The write protect switch of the SRAM card is valid (write protection), and therefore "Restore
for the first time only" cannot be set to valid.
Writing of backup data to the restoration destination drive was not normally completed.
