The difference between User permissions and User levels
User levels: There is a difference between high-level users and low-level users: the high-level
users can access to the screens which are set to the high-level, while the low-level users
cannot access to the screens which are set to the high-level. Each screen is encrypted based
on the user level.
User permissions: The permissions are not restricted for each user level. If user name and
password are entered correctly, the user can operate components which are restricted its
access. The user permissions allow the user to add or delete user accounts. The user
permissions can be set to the components, however, they are invalid to a password which is set
to the screen.

What if the uploading password or the online change password of the PT is lost
If the uploading password of PT is lost, data cannot be uploaded, and the only solution is to
download the project again to overwrite the original one.
Similarly, if the online change password is lost, it also requires to download the project again
and set a new password.
Thus, in order to guarantee the safety of users' projects, please back up the original projects,
for decryption is not within our service range.

Why cannot the system time be changed during offline test
Offline test uses the PC's clock, therefore the time cannot be changed. It can only be changed
when downloaded to the PT.

validate the operation, and at this time, the Confirm Operation function can fit well here. This
function can control components. For example, you can check the [Confirm Operation] on the
[Control Setting] attributes page of the bit status setting component, as shown below:
A dialog box as follows will pop up everytime you operate the components once this option is
checked:
