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?
We use mark 6e.
Yes we can in operator mode. Check with your I&C team, they can arrange for you. If I&C can not, check with GE vendor.
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.
