Setting the operation setting when a data backup error occurs
Set the operation to be performed when the data backup fails on some devices while being processed to multiple devices
supporting iQSS to the lower 8 bits of SD1367 (iQ Sensor Solution data backup/restoration operation setting).
■ Performing a data backup
Turn ON SM1361 (iQ Sensor Solution backup request) to request a data backup.
Data is backed up after a data backup request.
SM1361 is turned OFF when a data backup is completed.
1.
Checking the execution status of a data backup
The execution status of a data backup can be checked with the following special registers.
*1 For an iQ Sensor Solution related error (error code: 4805H), the number of devices in which the processing has been abnormally
completed is not counted.
2.
Canceling a data backup
Turn ON SM1367 (iQ Sensor Solution backup/restoration cancellation request) to cancel a data backup.
A cancellation is performed for each device supporting iQSS, so it will be canceled when a data backup which is being
performed to a device supporting iQSS at the time a cancellation request is made is completed.
3.
Checking the completion of a data backup
When the data backup is completed, the backup completion status can be checked with the following special relays.
• Normally completed: SM1362 (iQ Sensor Solution backup normal completion) is turned ON.
• Abnormally completed: SM1363 (iQ Sensor Solution backup abnormal completion) is turned ON.
The number of the folder where backup data was saved at the completion of data backup is stored to SD1375 (iQ Sensor
Solution backup folder number).
4.
Checking a data backup error
Even if a data backup of a target device supporting iQSS is completed with an error, a diagnostic error will not be detected.
Check the errors with the following special registers.
• SD1376 (iQ Sensor Solution backup/restoration error cause in a module) stores the error code of an error occurred in a
MELSEC iQ-R CPU module. (

• SD1377 (iQ Sensor Solution backup/restoration error cause in a device) stores the error code of an error occurred in a
device supporting iQSS. (

• Check a module or device in which an error has occurred from SD1378 to SD1382. (

Releasing the right to use
Set SD1360 to '0000H' in order to turn SM1360 ON . The right to use is released and the next data backup is ready to be
performed.
SM1360 is turned OFF when the right to use is released.
If the right to use is released even though it has already been done, SM1360 remains ON because no processing is
performed. In that case, turn OFF SM1360.
Operation on error Description
0H: Continue Set this to continue a data backup even if it fails on some devices.
1H: Stop Set this to stop a data backup if it fails on some devices.
Special register Description
SD1371 This register stores the number of target devices for each execution unit when starting a data backup or
restoration.
SD1372 This register stores the number of devices in which the processing has normally be completed for each execution
unit. (The number is incremented every time the processing of one device is completed normally.)
SD1373 This register stores the number of devices in which the processing has abnormally be completed for each
execution unit.
*1
(The number is incremented every time the processing of one device is completed abnormally.)
SD1374 This register stores the progress of processing being executed for a device in percent, from 0 to 100.
Backup folder number Description
0 to 99: Folder number The number (0 to 99) of the folder in which backup data was saved is stored.
FFFFH: Backup data not saved Backup data has not been saved.
