Data stored Details
Off: Not being executed This relay turns on during the backup of the
On: Being executed CPU module.
OffOn:Backup requested • At the timing when this relay turns from off
OnOff:Backup completed to on, the backup of the CPU module is
executed.
• This relay turns off at the completion of
the backup of the CPU module.
Off: Not being executed This relay turns on during the restoration of
On: Being executed the CPU module.
OffOn:Restoration • At the timing when this relay turns from off
requested to on during STOP, the restoration of the
OnOff:Restoration CPU module is executed.
completed • This relay turns off at the completion of
the restoration of the CPU module.
Off: Not being executed This relay turns on during the retry of the
On: Being executed automatic backup of the CPU module.
Data stored Details
OffOn:Right to use • This relay requests acquiring or releasing
requested the right to use of the data backup/
OnOff:Right to use restoration of iQ Sensor Solution.
acquired/released • 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.
OffOn:Backup requested • This relay requests the data backup of iQ
OnOff:Backup completed 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.
Off: Other than normal • This relay turns on when the iQ Sensor
completion Solution data backup is completed
On: Completed normally 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.
Off: Other than error • This relay turns on when the iQ Sensor
completion Solution data backup is competed with an
On: Completed with an error. The error code is stored into
error 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.
