When automatic restoration did not complete normally, "RESTORE ERROR" (error code: 2228) occurs.

(7) Functions that cannot be executed during restoration
Functions that cannot be executed during restoration are the same as those cannot be executed during data
backup. (
(8) Precautions
• Do not perform the following operations during restoration.
• Insertion/removal of a memory card or SD memory card
• Power-off of the CPU module
• Reset
• Even when a memory card storing backup data files is inserted to the Universal model QCPU whose serial
number (first five digits) is "10101" or earlier, and the CPU module is powered off and on or is reset, the
system ignores the files. (No diagnostic error is detected.)
• Do not use a memory card or SD memory card where a parameter file with boot settings is stored. If used,
data are overwritten according to the boot settings even data are restored.
• If restoration is started using a programming tool, the CPU module stops the operations of the following
functions. The operations do not resume even after data are restored.
• Refresh of network modules
• Refresh of CC-Link IE Field Network Basic
• Data link transfer
• Auto refresh of intelligent function modules
• Auto refresh of CPU shared memory
• If the model of a restoration-target CPU module differs from that of a backup-source CPU module,
"RESTORE ERROR" (error code: 2225) occurs.
• Check that the free space of the standard RAM in a restoration-target CPU module is larger than backup
data. If a backup-source CPU module uses an extended SRAM cassette, "RESTORE ERROR" (error code:
2228) occurs in the following cases.
• Even though a backup-source CPU module uses an extended SRAM cassette, a restoration-target
CPU module is not using it.
• The size of the extended SRAM cassette used with a restoration-target CPU module is smaller than
that of the extended SRAM cassette used with a backup-source CPU module.
• If the restoration processing is performed while the CPU module is locked with a security key, an error
occurs.
272
The model of a restoration-target CPU module differs from that of a backup-source CPU module.
• Backup data file is corrupted. (The contents of backup data file do not match with the check code.)
• Reading backup data from a memory card or SD memory card did not complete normally.
• Since the write protect switch of an SRAM card or SD memory card is valid, the "Restore for the
first time only" parameter cannot be set.
Writing backup data to the restoration-target drive did not complete normally.
Free space of the standard RAM in a restoration-target CPU module is not enough.
