Password Protection
Preventing
To prevent unauthorized operation of the OP, there is the possibility of pro-
unauthorized tecting access by means of passwords and password levels. This is possible
operation
for the call of functions and inputs.
6.1 Password Levels and Access
Password
When you are configuring, you assign ascending password levels from 0 to 9
hierarchy for functions called on the OP by function keys, soft keys and input fields.
The password levels assigned to standard screens are listed in Appendix A.
Issue of a password to an operator means that permission is granted simulta-
neously to execute functions at a specific password level.
Password level 0
At this level, the lowest in the hierarchy, functions are assigned which, when
executed, have no or little effect on the course of the process; these are nor-
mally calls of functions not having input options – for example, viewing mes-
sage buffers.
A password is not required to call functions of password level 0.
If an operator calls a function of a level other than 0, he is prompted on the
display to enter a suitable password.
Password levels 1
Levels 0 to 8 are assigned to functions of ascending importance.
to 8
A password level is assigned to a password by the superuser as part of his
password management responsibilities.
Password level 9
Permission to execute functions of password level 9 is the sole responsibility
of the superuser, who has access to all OP functions. Only the superuser is
allowed to perform password management.
The password for level 9 functions is created at the time of configuration.
Synonymous with password level 9 is use of the authorization input.
If an operator logs in with the password of a specific password level on the
display, he is authorized to execute functions of this and lower levels.
