Only User Password Designated
You must enter the user password to gain access to the
program.
Only Master Password Designated
You do not have to enter the master password to gain
access to the program. A master password is used by itself
to allow access if a user password has been entered.
User Password and Master Password
Designated
You must enter either the user password or the master
password to gain access to the program.
Generally, if you are using a number of controllers, each controller is given a
different user password and a master password is applied to all of the
controllers. You can use the master password to change or remove any
password.
Important: There is no password override to defeat the protection. Contact
your Allen-Bradley representative if you are not able to locate
your password.
To enter a user password and/or master password:
1. Access the program configuration menu.
2. Arrow down to the option USER PASSWORD or MASTER PASSWORD and
select it.
