5.12.7.4 Temporary Unlock of File Password

To work with a password-protected file on GX Works2 for the following operations, temporarily unlock the file password. The
temporary unlock of a file password is achieved by inputting the registered file password for verification and temporarily
disable unlock for file operation. If the password verification fails, you cannot operate the file.
For instance, when read-protecting a program file with password on a certain session of GX Works2, and then reading from
PLC on another session of GX Works2, temporarily unlock the file password by verifying it.
Temporary password unlock is valid only in the GX Works2 program on which the file password is unlocked. To work with a
file on a separately started session of GX Works2, temporarily unlock the file password again.
Temporary password unlock is valid until the GX Works2 program in which the file password was unlocked is ended.
