4.6 Setting Up User Accounts
4.6.1 System Administration, Passwords, and Privilege Levels
In a plant with many users with various levels of training and responsibility, it is often
desirable to restrict certain users access to a limited range of functions. Starting the
ValveNavi program requires a valid account with a user name and a password for each
user. The privilege level associated with a ValveNavi account determines which functions
of the program the user is allowed to access.
The ValveNavi Administration program allows the administrator to perform all user account
administrative functions to run ValveNavi and to control access to the functionality of the
YVP positioner.
These administrative functions include:
• Adding new user accounts
• Deleting existing user accounts
• Changing existing user accounts
• Adjusting privilege levels
4.6.2 Start the Administration Program
After installation of ValveNavi, the ValveNavi administrator should change the default
passwords, set up the initial user accounts through the Admin program, and secure the
setup disk. Anyone with access to the setup disk could reload the software and thereby get
access to YVP devices.
To start ValveNavi Admininistration, select Start->Program->ValveNavi->ValveNavi
Admininistration. The administrative program prompts you for a logon name and password.
Log in for the first time with an administrator account. Enter the default logon name
(“Admin”) and leave password blank. (Note: The system is case sensitive, and you must
type the default names in correct case.) Then, clicking OK to open the VFAdmin dialog
(Figure 4.5).
