22 DATA BACKUP/RESTORATION FUNCTION
22.2 Restoration Function
Restoration processing triggered by turning on SM1354
Backup data is restored at a desired timing. When restoration is requested, the CPU module backup data based on the
following files in the designated folders are restored.
• System file for backing up CPU module data
• Backup data file for backing up CPU module data
• Device/label data file for backing up CPU module data
Restoration, triggered by turning on SM1354, should be used to check the backup data or to check the
operation before running the main one. To start main working operation of the system with the backup data,
use automatic restoration using SD955 or restoration with CPU module auto exchange.
The restoration processing triggered by turning on SM1354 (Data restoration execution request) can be
executed only when the CPU module is the STOP state.
Operating procedure
1. Set restoration target data with SD954 (restoration target data setting).
* 1
2. Set restoration target folders with SD956 (Restoration target date folder setting) to SD958 (Restoration target number
folder setting). (However, this is not required when SD955 (restoration function setting) b13 (restoration target folder) is
turned ON in step 3.)
3. Set each setting with the b13 to 15
*2
of SD955.
4. Set the CPU module to the STOP state.
5. Turn on SM1354 (Data restoration execution request).
*1 Only 1 (only device/label data) is valid with firmware version of FX5U/FX5UC CPU module earlier than "1.050".
*2 The b15 (operation after restoration setting) setting is required when the firmware version is "1.050" or later for the FX5U/FX5UC CPU
modules.
If the restoration processing is completed with an error and SM959 (Data restoration error check flag) turns on, check SD959
(Restoration error cause), take actions, and then restore the data again as required.
The execution status of the restoration processing can be checked with SD1350 (Number of uncompleted
folders/files of CPU module data backup/restoration) and SD1351 (Progression status of CPU module data
backup/restoration). (Page 211 Progress of the backup/restoration processing)
(1) Turn on SM1354.
(2) The system turns on SM1353 (Data restoration status flag).
(3) The system turns off SM1354 after the restoration processing is
completed.
(4) The system turns off SM1353.
