(3) Procedure
For the execution procedure using a display unit, refer to  Page 281, Section 4.7.4.
For auto loading, set a desired folder number in SD909 (Auto loading target folder number).
To execute auto loading without specifying the folder number, set 0 (default) in SD909. (The load target folder
name is "AutoLoad".)
The auto loading procedures for each case are described below.
(a) When the folder number is not specified
1.
Save data into the SD memory card by the batch save function of a display unit or using GX
Works2.
2.
Change the name of the saved data folder to "AutoLoad" using a personal computer.
3.
Power off and on or reset the CPU module.
4.
Data in the "AutoLoad" folder are automatically loaded to the CPU module.
● Auto loading cannot be performed if the SD memory card is write-protected.
Remove write protection from the SD memory card, and execute auto loading.
● When the "AutoLoad" folder exists, data in the folder are automatically loaded whenever the CPU module is powered off
and on or is reset.
To prevent this, change the folder name.
● When 0 (default) is set in SD909 and no "AutoLoad" folder exists, an error does not occur. This is because the CPU
module determines that auto loading is disabled.
● If any folder or file (including read-only files) with the same name exists in the load-destination CPU module, data in the
corresponding folder or file will be overwritten.
(b) When the folder number is specified
1.
Save data into the SD memory card by the batch save function of a display unit or using GX
Works2.
2.
Change the name of the saved data folder to "AutoLoad**" using a personal computer.
Specify any number between 01 and 99 at "**".
3.
Set the number assigned in Step 2 in SD909.
For example, when the folder name is "AutoLoad01", set "1" in SD909.
4.
Power off and on or reset the CPU module.
5.
Data in the specified folder are automatically loaded to the CPU module.
● Auto loading cannot be performed if the SD memory card is write-protected.
Remove write protection from the SD memory card, and execute auto loading.
● The value in SD909 returns to 0 (default) upon completion of auto loading.
If the "AutoLoad" folder exists even after completion of auto loading, data in the folder will be automatically loaded again
when the CPU module is powered off and on or is reset next time.
● If any folder or file (including read-only files) with the same name exists in the load-destination CPU module, data in the
corresponding folder or file will be overwritten.
