6 Maintenance and Troubleshooting

The difference between User permissions and User levels
User levels: there is a difference between high-level users and low-level users - high-level users
can access low-level windows, while low-level users can not access high-level windows. Whole
windows can be encrypted based on user levels.
User permissions: user permissions are not restricted by user levels. As long as the user's
name and password are input correctly, the component which is set limited for access to it can
be operated. With the user permission, user accounts can be added or deleted. User
permissions only work on components, and have nothing to do with the window password.

What if the uploading password or the online change password of the HMI is lost
If the uploading password of HMI 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 simulation
Offline simulation uses the PC's clock, therefore the time cannot be changed. It can only be
changed when downloaded to the HMI.

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