6.2 Login/Logout on OP (LOGIN/LOGOUT)
You can log in on the OP in different ways:
by means of the standard screen Password
→
Login,
if a function call is made on the OP for which the current password level
is too low, you are automatically prompted on the display to enter the cor-
responding password,
by means of the authorization input (in special cases – for example, dur-
ing the commissioning phase) corresponding to password level 9.
1. From the standard screen, choose Password
→
Login.
The password input screen is shown on the display. This screen is similar-
ly 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 on the system keyboard and terminate by pressing
ENTER .
The cursor jumps automatically to the next field every time a character is
entered. The input of every character is represented by an asterisk (*) in
the input area. The cursor is no longer visible after the last character has
been typed.
If the password is valid, the corresponding password level is shown on the
display.
3. Exit from the standard screen – for example, by pressing the ESCAPE
key.
If a function requires a higher password level than the current one, you are
automatically requested to enter a suitable password when the function is
called. After entering the password, you return to the calling function by
pressing ESCAPE.
During commissioning, it may be useful to avoid repeated logins on the OP
as the superuser. This is possible if the authorization input is connected on
the terminal strip of the OP to the authorization output by means of a lock
switch or a bridge or if a dc voltage (+ 15 to 30 V) is applied to the autho-
rization input. The OP then automatically assumes password level 9, i.e. wi-
thout requesting a password.
Choose the standard screen Password
→
Logout.
Upon selection of the standard screen, the OP switches from the current pass-
word level to the lowest password level, level 0, and branches to the message
level.
