The model of a restoration-target CPU module differs from that of a backup-source CPU module.
• Backup data files do not match.
• Reading backup data from a memory card or SD memory card did not complete normally.
Writing backup data to the restoration-target drive did not complete normally.
Restoration started while latch data were backed up to the standard ROM.
Restoration started while data were being written to the running CPU module (during online
change).
Restoration started while an external device (FTP client) is communicating with the CPU module
using the FTP.
Restoration started while another restoration was being executed.
• Restoration started without a memory card or SD memory card being inserted.
• Restoration started while use of the SD memory card is disabled with the SD memory card lock
switch.
• Restoration started while use of the SD memory card is disabled by SM606 (SD memory card
forced disable instruction).
Free space of the standard RAM in a restoration-target CPU module is not enough.
Restoration started while the data logging function was being executed.
Restoration started while the iQ Sensor Solution function (data backup/restoration) was being
executed.
Restoration started while the CPU module data backup/restoration function was being executed.
