Error
Error Contents and Cause
Code
[RESTORE ERROR]
• The device information (number of points)
backed up by the device data backup function is
different from that configured in the PLC
Parameter dialog box.
Perform a restoration per power-on and reset until
the number of device points is identical to the
2220
value set in the PLC Parameter dialog box or until
the backup data are deleted.
■Collateral information
• Common information: File name/Drive name
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[RESTORE ERROR]
• The device information backuped by the device
data backup function is incomplete. (The power
may have been off or the CPU module may have
been reset during performing the backup.)
Do not return the data when this error occurs. Also,
2221
delete the incomplete device information at the
time of this error occurrence.
■Collateral information
• Common information: File name/Drive name
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[RESTORE ERROR]
The model name of the restoration destination
CPU module is different from the one of the
backup source CPU module.
2225
■Collateral information
• Common information:-
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[RESTORE ERROR]
• The backup data file is corrupted.(The backup
data file does not match the check code.)
• Reading the backup data from the SRAM card
did not end successfully.
• Since the write protect switch of the SRAM card
is set to on (write inhibited), the checked
"Restore for the first time only" setting cannot be
performed.
■Collateral information
• Common information:-
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
2226
[RESTORE ERROR]
• The backup data file is corrupted. (The backup
data file does not match the check code.)
• Reading the backup data from the SD memory
card did not end successfully.
• The "Restore for the first time only" setting
cannot be enabled because the write protect
switch of the SD memory card has been set to
on (write-prohibited).
■Collateral information
• Common information:-
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
12-34
Corrective Action
• Set the number of device points at the time of
backup to be identical to the device point value
set in the PLC Parameter dialog box. Then turn
on from off or reset the power supply.
• Delete the backed up data, turn the power
supply from off to on, and reset.
Reset the CPU module and run it again.
Execute a restore for the CPU module whose
name is same as the backup source CPU
module.
• Execute a restore of other backup data
because the backup data may be corrupted.
• Set the write protect switch of the SRAM card
to off (write enabled).
• Restore with any other backup data because
the backup data may have been corrupted.
• Set the write protect switch of the SD memory
card to off (write-enabled).
