The operator terminal will determine the user level from the entered password.
For instance, if the level of the password entered by the user is
1
, then the oper-
ator terminal will set the user level to1; if the level of the password entered by
the user is
2
, then the operator terminal will set the user level to 2.
User level 1
has the highest privilege and
User level 9
has the lowest.
Scenario 2: Re-entering a password
The object
Action Button
in CP400Soft also allows the designer to create a but-
ton which asks the user to re-enter a password.
In the example below, the
button is used to prompt a user to re-enter a
password. After entering the password, the operator terminal will update the
user level according to the most recent password which has been entered. There-
fore, this button can be applied to raise or drop one’s privileges while the oper-
ator terminal is in operation.
How to configure an
Action Button
is described in the CP400Soft User’s
Manual.
Scenario 3: Password-protecting a button in the operator terminal
The designer can create a button which is protected by a password for execution.
For example, a
Goto Screen
button can be designed with a high level of security;
which means that a password with a high level of privilege is required in order
to open the other screen. As the button is selected and the current user has a low-
er privilege than has been set for the button, the operator terminal will prompt
the user for a password. The user will need a password with at least the level of
privilege that has been set for the button. This function can restrict users to ac-
cess to certain parts of the application.
Note:
Only users of
User Level 1
has the right of access to the password table.
