A
CPU module data backup/restoration function
The following is the list of special relay areas relating to the CPU module data backup/restoration function.
*1 The CPU module where this function can be used supports these special relay areas.
iQ Sensor Solution data backup/restoration function
The following is the list of special relay areas relating to the iQ Sensor Solution data backup/restoration function.
No. Name Data stored Details Set by (setting timing) CPU
SM1350 CPU module data backup
status flag
Off: Not being executed
On: Being executed
This relay turns on during the backup of the
CPU module.
S (Status change) Rn
*1
SM1351 CPU module data backup
execution request
OffOn:Backup requested
OnOff:Backup completed
• At the timing when this relay turns from off
to on, the backup of the CPU module is
executed.
• This relay turns off at the completion of
the backup of the CPU module.
S (Status change)/U Rn
*1
SM1353 CPU module data
restoration status flag
Off: Not being executed
On: Being executed
This relay turns on during the restoration of
the CPU module.
S (Status change) Rn
*1
SM1354 CPU module data
restoration execution
request
OffOn:Restoration
requested
OnOff:Restoration
completed
• At the timing when this relay turns from off
to on during STOP, the restoration of the
CPU module is executed.
• This relay turns off at the completion of
the restoration of the CPU module.
S (Status change)/U Rn
*1
SM1356 Retry status flag for CPU
module data automatic
backup
Off: Not being executed
On: Being executed
This relay turns on during the retry of the
automatic backup of the CPU module.
S (Status change) Rn
*1
No. Name Data stored Details Set by (setting timing) CPU
SM1360 Right-to-use request for iQ
Sensor Solution data
backup
OffOn:Right to use
requested
OnOff:Right to use
acquired/released
• This relay requests acquiring or releasing
the right to use of the data backup/
restoration of iQ Sensor Solution.
• At the timing when this relay turns from off
to on, the relay requests the right to use
with the value specified in SD1360.
• This relay turns off when the right to use
has been acquired or released.
S (Status change)/U Rn
*1
SM1361 iQ Sensor Solution backup
request
OffOn:Backup requested
OnOff:Backup completed
• This relay requests the data backup of iQ
Sensor Solution.
• At the timing when this relay turns from off
to on, the backup of the set device(s) is
executed.
• This relay turns off at the completion of
the data backup of iQ Sensor Solution.
• This relay turns from on to off when the
right to use is acquired.
S (Status change)/U Rn
*1
SM1362 iQ Sensor Solution backup
normal completion
Off: Other than normal
completion
On: Completed normally
• This relay turns on when the iQ Sensor
Solution data backup is completed
normally.
• When the iQ Sensor Solution data backup
is completed with an error, SM1363 turns
on and this relay remains off.
• This relay turns from on to off when the
right to use is acquired or the backup is
requested.
S (Status change) Rn
*1
SM1363 iQ Sensor Solution backup
error completion
Off: Other than error
completion
On: Completed with an
error
• This relay turns on when the iQ Sensor
Solution data backup is competed with an
error. The error code is stored into
SD1376 or SD1377.
• When the iQ Sensor Solution data backup
is competed normally, SM1362 turns on
and this relay remains off.
• This relay turns from on to off when the
right to use is acquired or the backup is
requested.
S (Status change) Rn
