5.17.2 Reactivate Password Protection
The access authorization for a mask or variable is reset when the fol-
lowing is carried out:
– The operating device is switched off and back on again.
– The wrong password is entered.
– A logical 1 is written to the PR bit of the Write coordination byte.
– The system variable MskchgResPasswd is activated.
– The option Reset Password is selected in the mask parameters of
the password-protected mask.
5.17.3 Password Mask and Password Functions
You can create a password query mask. This mask will then appear
when you try to go to a password-protected mask, and you have not
already entered a password with sufficient authorization.
As soon as you enter a password with sufficient authorization in the
password query mask, and select the Data Release key, the system
opens the mask previously selected. No restrictions apply to the other
content (for example, texts, other variables, and soft keys) in the mask.
For each mask of the user interface, you can specify whether password
protection will be activated after you exit the mask.
If the operator has not entered a valid password, it must be possible to
exit the mask. You can program the cursor key Home to do this, for
example.
If you do not create a password query mask, the operator must enter a
password in masks specifically provided for this purpose.
You can deactivate password protection entirely by writing the value 1
to the system variable PasswdInactive.
The operating device then behaves as if each mask were created with
an edit and view level of 0. The system variable is battery-backed, that
is, the deactivation still has an impact after you switch on the operating
device again.
5.18 Real Time Clock in the Operating Device
Each operating device has a real time clock. You set the parameters of
the real time clock in the system parameters. You use system variables
to set the time, date, and weekday in the operating device, and insert
