It is necessary to set up user accounts for all personnel who will access the
SCADA system. Each user is assigned a security level based on the level of
functionality that he/she needs to access. The user accounts are set up as follows
(refer to Fig. 2-5):
With Lookout launched, select Options >> User Manager. In the dialog box
select User >> New User. In the New Lookout User dialog box enter the
following information:
Username: Name that the user will log in with.
Full Name: Full name of the user.
Description: A description of the account.
Password: An Alphanumeric password (at least 5 elements long).
Security Level: Security level for the user per the above table
Click OK
.
Repeat above steps for each new user account that needs to be created.
Please note that Lookout security is capable of creating and using user groups.
Please refer to Chapter 6, Security of the Lookout Developer’s Manual.
To log into the system the user needs to click on login box located on the left side
of the task bar next to the date and time box. This box will display the user name
of the currently logged in user. If no user is logged in, the box will read
“nobody”. In the login dialog box, the user has the option of entering an Idle
time value which would be the time in minutes after which Lookout would log
the user out if there is no mouse or keyboard activity. The default value of zero
means that the automatic log off feature is disabled (refer Fig. 2-6).
