6.2 Logging-in and logging-out on the OP (LOGIN/LOGOUT)
You can log into the OP
via the standard screen Password processing Login
by calling a function for which the current password level is too low.In
this case, the OP automatically prompts you to enter a password.
Step Procedure Result
1 Select the standard screen
Password processing
Login.
The password input screen is
shown on the display. This
screen is similarly displayed
when a function call is made
for which the current password
level is too low. The cursor is
located in the first field of the
input area.
2 Enter the password by means
of the system keyboard. The input begins left-aligned.
Each character entered is re-
presented by an asterisk (*).
3 Confirm your input
by pressing
or cancel the input
by pressing
ENTER
ESC
– If the password is valid, the
standard screen is exited.
– If the password is invalid,
you can either repeat your
input or cancel.
If a higher password level than the one currently valid is required for operat-
ing a function key/soft key or an input field, the OP automatically prompts
you to enter a suitable password beforehand.
If you do not make an input at the OP during a configured time period, the
current password level is automatically reset to zero and the OP branches to
the message level. This ensures that the OP cannot be operated by unautho-
rized persons.
You can also log out of the OP via the standard screen.
Select the standard screen Password processing Logout. The OP then
switches from the currently valid password level to the password level zero
and branches to the message level.
