If you select [Overwrite], after updating the
passwords on the display unit, you can use the passwords in the
password setting only. If you select [Append], after updating the
passwords on the display unit, you can use both existing passwords
and the passwords in the password setting.
If you select the [After the password is
reflected, erase the CSV file] check box, the password setting data
saved on the external storage will be deleted after showing the
password on the display unit.
In order to edit the password again, you will need to prepare
password settings in CSV format.
Note that the password setting data is not deleted if you failed to
show the password.
