11.5 Overriding Password
Commands can be entered on the command line by double-clicking on System
Signals in the Setup folder in the Project Manager. By entering the command
PSxxxxxxxx, where xxxxxxxx represents the password, this password can be used to
override all other password levels, and the user gains access to everything in the
operator panel. This can be useful, for example, in performing support and mainte-
nance. Only capital letters can be used on the command line.
11.6 Changing Password in the Operator Panel
The password can be changed in the operator panel with the function Change login
password for function or touch keys. When a function or touch key linked to
Change login password is pressed a dialog box is shown, where the passwords for se-
curity levels below or at the same level as the in-logged person can be changed. See
the chapter Function Keys for further information.
11.7 Password Handling via USB Flash Drive
In some situations it can be convenient to use a USB Flash drive to handle a pass-
word. Not available for E1012 and E1022. This is possible by using the PWDF com-
mand under Setup/Commands.
Password levels are set in the configuration tool in the regular way. Then a USB Flash
drive is prepared with a file named “password.txt” that contains the password for the
desired security level. When the USB Flash drive is connected to the operator panel,
the panel searches for the password on the USB Flash drive and logs in to the correct
security level. When the USB Flash drive is disconnected, the security level is reset to
the default level.
Normally, a question about creating a backup file structure is displayed when a USB
Flash drive is connected. To deactivate this question, the DBAF command is entered
under Setup/Commands.
Note:
The PS password does not override the PD password.
Note:
It is not possible to select a security level on block 0.
Note:
After logging out, the [PREV] key and the function Return to previous block for
function and touch keys are ignored, to prevent unauthorized persons from accessing
blocks protected by passwords.
