• You can set a dedicated password. In the Security dialog box, on the Options tab, select the Use
Password to open a Project check box, and then set the password. The dedicated password is
applicable to the following operations:
- Opening projects
- Reusing screens
- Opening projects after uploading project data
• To password protect operations, the lowest level security group out of the security groups enabled with a
password must be assigned to a user account.
The security levels, from highest to lowest, are Administrator > Operator > Reader.
Example: To password protect the operation to display Device Monitor, assign the Operator security
group to a user account. If a user account assigned to the Operator security group does not
exist, the operation is not password protected.
• The commands that the USB Autorun function can execute vary based on the enabled security group. For
details, refer to Chapter 31 “2.4 USB Autorun Function Security” on page 31-34.
