Program Security

You can set separate passwords for ladder programs and motion programs. A lock mark is dis-
played for each password-protected program. To edit a password-protected program, you
must first enter the password.
The purpose of this password is to control access for editing. It does not affect the manage-
ment of program files (copying, cutting, pasting, deleting, or enable/disable settings).
If you forget the password that you set, there is no way to recover it, and it will be impossible to
open the password-protected program.
Important
This section describes the security that is provided, using a ladder program as an example.
Setting the Password
1.
In the Ladder Pane, right-click on the program for which you want to set a password.
Select Set the Password from the pop-up menu.
The Program Password Dialog Box will be displayed.
2.
Enter 1 to 8 alphanumeric characters in the New Password Box. Enter the same pass-
word again in the Password (Confirm) Box, and then click the OK Button.
Note: 1. The OK Button will be enabled when one or more characters are entered in the Password (Con-
firm) Box.
2. The password is not case sensitive.
The Program Password Dialog Box will be closed, and a padlock icon will be displayed next to the
ladder program that was selected in Step 1. If the program was displayed in the main window, it will
be closed.
