7 Security
The MCT security model provides an administrator with the tools to add up to 30 users to the system. Each
user must have a unique ID, full name and password. Four user levels are provided which include system,
user, supervisor and administrator levels. Specific access rights can be assigned to each user level and
password aging can be implemented. Verification is provided (if enabled) for any parameters that will change
a control parameter, which could upset the process (i.e. loop set point, start/stop automated ramp/soak
programs, etc.).
Verification requires that the logged in user must log in again before the process value (at the controller) will
actually be changed. This feature is provided for extra security. The following example will make re-
authentication clearer:
A supervisor logs on the system. The supervisor then steps away from the system to take a phone call but
does not log out before leaving. If another user tries to change the control set point on any loop, the system
will require another login (by an authorized user for that level) before the control set point is actually changed.
This provides an extra level of protection to make the system more “tamper proof”.
The Security menu is accessed from the home menu and provides access to the security section of the MCT.
The Security menu provides the following functions:
Configure
Provides access to security setup to add users, set rights and options.
Login
Log on a user if security is enabled.
Log Off
Log off a user if security is enabled.
Audit
Allows the user to view any of the saved audit trail files.
User
Shows the current user logged into the system.
Password
Allows the current user to change their password.
