3-13 Security Level
Security Level is used to set the access authority for different users to enhance the security of the
project. Only the user having the high-level password can access the high-level screen, thus enhancing
the security of the project significantly.
When setting Screen Property, we can see one column of “Security Level”. That’s to say, we can specify
the Security Level for any screen, as shown below:
The Security Level is only valid for the Base Screen. One project has 3 Security Levels, i.e. High (2),
Common (1) and Low (0) by default. The default security level is Low when creating a new screen. You
can set different passwords for each security level in the [PT Property].
The user with higher security
level can access the screen with the lower security level, while the user with the lower security
level can’t access the screen with the higher security level.
Such kind of method is helpful to the
security management. For example, we can place the important switches into the screen with the
higher security level, so the user can’t access them after they enter this screen, and the contents can
be accessed only after the password for the higher security level is input.
Here is an example about security level usage: Firstly, select [File] / [New], and double-click PT in the
Project Work Space, then set The number of Security Levels to 3, 1-level Password to 1111 and 2-level
Password to 888888 in Security Levels Setting tab of PT Property dialog box, as shown below:
