MON20/20 Software for Gas Chromatographs User Manual
SEPTEMBER 2010 3-9000-745
7-17
7.3 Managing users
Use the User
Administration
commands to create or
delete users, change
passwords, and to
monitor PC-to-GC
connections.
Login security is at the gas chromatograph level instead of at the
software level. This means that you no longer have to log in after starting
MON 20/20—but you do have to log in to the gas chromatograph to which
you are trying to connect. This also means that if you create a new user,
that user is only valid for the GC to which you are connected. You cannot
connect to any other GC unless you create the same user on it first.
MON 20/20 recognizes the following four user types, or roles, each with
an increasing level of access to functionality:
• Read-only - A read-only user has the lowest level of access and can
view data but cannot make any changes. A read-only user can change
his or her password only.
• Regular - A regular user has all of the privileges of a read-only user,
as well as the ability to acknowledge and clear alarms. A regular user
can also control the GC through MON 20/20’s Control menus. A
regular user can change his or her password only and cannot create or
delete other users.
• Super User - A super user has all of the privileges of a regular user,
as well as the ability to manage and control the GC through MON 20/
20’s Application and Hardware menus. A super user can change his or
her password only and cannot create or delete other users.
• Administrator - An administrator has complete access to all of MON
20/20’s commands and functions, as well as the ability to manage all
other users by creating or deleting user accounts, and changing
passwords.
