I need to know we need a read only user at toolbox without being able to made force, or any modify. Just read the logic and live data. Is this possible?
In Toolbox, you can set a password for Privilege Level 1 and above (change online values). Open your M6B file for a controller, and use the Options->Passwords menu option. Don't forget your password, I'd make a backup of your unprotected M6B in a safe place.
