(5) Functions that cannot be performed during backup
Table6.55 shows functions that cannot be performed during backup.
(6) Precautions
(a) Do not perform the following operations during backup.
• Mounting/removal of a memory card
• Power-off of the CPU module
• Reset
(b) Even if booting parameters backed up with contacts for the Universal model QCPU
having the serial number (first five digits) is "10101" or earlier, the system ignores
the parameters.
In this case, even if the backup start setup contact or backup start contact set by the
parameters is turned on, the operating status of the CPU module does not change (a
diagnostic error is not detected).
(c) After backup is ready to start, the following functions stop (do not resume the
operations even after the backup).
• Refresh of network modules
• Data link transfer
• Auto refresh of intelligent function modules
• Auto refresh of CPU shared memory
