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 window, thus enhancing
the security of the project significantly.
When setting Window Attribute, we can see one column of "Security Level". That's to say, we can
specify the Security Level for any window, as shown below:
The Security Level is only valid for the Basic Window instead of the other windows. One project
has 3 Security Levels, i.e. High (2), Common (1) and Low (0). The default security level is Low when
creating a new window. You can set different passwords for each security level in the [HMI Attribute].
The user with higher security level can access the window with the lower security level, while
the user with the lower security level can't access the window 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 window with the higher security level, so the user can't access them after they enter
this window, 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 HMI in the
Project structure window, then set The number of Security Levels to 3 and 0-level Password to NULL, 1-
level Password to 1111 and 2-level Password to 888888 in Security Levels Setting tab of HMI Attribute
dialog box, as shown below:
