# User Access Standard Mode

In this mode, the user can define any number of users and assign each an access level from (1 - Operator to 5 - Administrator).

To log on, a User can use:

- $System.Users.Login(username, password): Attempt to log in with a specified user name/password.

Once a user is logged in, The Users.CurrentUsername and Users.CurrentAccessLevel tags are updated for the newly logged in user.

Users can be added and removed at runtime through these functions:

- $System.Users.AddUser(username,password,accesslevel): Add a new user
- $System.Users.DeleteUser(username): Remove a user
- $System.Users.UserExists(username): Check if a user exists.

Note: Users can also be setup through User Configuration, by double-clicking the Users node under System in the Project Explorer.
