5.12.6 File Password: Cautions on Setting

When you forgot the password
If a registered password is forgotten, file operation other than Format PLC Memory becomes impossible. Format PC memory
if the registered password is forgotten. Not only the password but all data will be cleared; recover data by opening deleted file
on GX Works2 and write it to PLC again.
When reading file
When password-protected files are read from the CNC controller to GX Works2, password information is not read. This
means that password is not set even if the read file is written to the CNC controller again.
Precaution for setting file password to simple project (with labels)
When at least one file password is registered to a sequence program which was written to a CNC from simple project,
programs with no password set also are required to input password to be read or written, not only the program protected by
the password.
When a sequence program is created by simple project, password registration only for the specific program cannot be
performed.
