Changing the access
authorization
The screen is not automatically updated after a change in access
authorization (e.g. when the keyswitch position is changed), but only
when the screen is next refreshed (e.g. on closing and opening a
directory).
The currently valid access authorization is checked every time a
function is executed.
If the PLC is in the stop state, the input image of the machine control
panel is not scanned. For this reason the keyswitch positions are not
evaluated during start-up.
Passwords As an additional option for setting access authorization, it is possible
to enter three passwords in the "Start-Up" operating area.
If the password is set, the keyswitch positions are irrelevant.
