Restoration for the CPU module change function

This function restores data backed up in a memory card or SD memory card to a replaced CPU module.
(1) Restoration using a programming tool
Data restoration using a programming tool can be performed on the "Restoration execution from backup data"
window.
[Online]
Click "Execute" to start restoration, select "Yes" in the screen appears, and power off and on or reset the CPU
module. The restored data becomes valid. For details, refer to the following.
Operating manual for the programming tool used
(2) Automatic restoration
Check the "Auto restore at turn OFF  ON or reset" checkbox in the PLC Module Change Setting window,
opened by clicking the button in the PLC system tab of the PLC parameter dialog box. (
3.31.1 (1) (b)) After data are backed up and the CPU module is powered off and then on or is reset, restoration
automatically starts. Optional items listed in the following table can be set at the same time.
Option setting item
Restore for the first time only
Restore every time
*1 This setting is valid only when backup data are stored in the ATA card or SRAM card.
Note if the write protect switch of the SRAM card is set to be valid (write protection), the setting does not become valid
and the data are restored even after the first time. ("RESTORE ERROR" (error code: 2226) occurs.)
*2 When using the FLASH card, restoration can be performed even after the first time.
*3 Data are restored using a programming tool for the second time and later.
Data are restored during initial processing after the CPU module is powered off and then on or is reset. After the
data are restored, the operating status of the CPU module shifts to the one set with the RUN/STOP/RESET
switch. Therefore, powering off and then on or resetting the CPU module again is not required.
If a memory card or SD memory card needs to be changed after restoration, turn on SM609 (Memory card
remove/insert enable flag), check that SM600 (Memory card usable flags) turns off, and then change the card.
