FUNCTIONS
• Connect GX Developer to the CPU module.
Write the set remote password to the CPU module.
When a multiple CPU system is configured, write the remote password to the
control CPU of the module to which the remote password is set.
Note6.61
Note63
• When the PLC is powered OFF and then ON or the CPU module is reset, the
remote password is made valid for the module.
POINT
1. After setting the remote password, store the parameters to the program
memory (Drive 0).
Note6.62 Note6.63
If the parameters are stored into other than the program memory (Drive 0),
the remote password function will not be performed normally.Note64Note65
2. When executing boot run, store the parameter file into the standard ROM or
memory card and make setting to transfer the parameter file to the program
memory in the boot file setting of GX Developer.
Note6.62 Note6.63
At this time, set the parameter-valid drive settings, i.e., DIP switches to the
standard ROM or memory card that stores the parameter file. (If the DIP
switches are set to the program memory, boot run will not be executed
normally.)
(b) Remote password change
• In the project data list of GX Developer, choose [Parameter] [Remote pass]
to display the Remote password setting screen.
• Change the password and write the new password to the CPU module.
(c) Remote password deletion
• In the project data list of GX Developer, choose [Parameter] [Remote pass]
to display the Remote password setting screen.
• Click the button to delete the set password.
• Write the remote password by GX Developer.

Basic
Since the Basic model QCPU always stores parameters to the program memory, it is not
necessary to be conscious of the description in POINT.
Basic
Note6.62
Since the remote password is valid with the Universal model QCPU as long as parameters are
stored in the valid drive, it is not necessary to be conscious of the description in POINT.
