Password Protection
Password protection can be configured for function keys/soft keys and input
fields in order to permit only authorized persons to work with the OP .
6.1 Password Levels and Access
When configuring with ProT ool, the function keys/soft keys and input fields
are assigned hierarchically ordered password levels from 0 to 9, 0 being the
lowest and 9 the highest level in the hierarchy . The password levels of the
standard screens are listed in Appendix A.
At the same time as you assign a password to an operator or to an entire
group of operators, you also assign them authorization to execute functions of
a certain password level.
When you log in with the OP under a password of a certain password level,
you are given the authority to execute functions of this password level and
functions from lower levels.
At this level, the lowest in the hierarchy , functions are assigned which, when
executed, have no or little ef fect on the course of the process; these are nor -
mally calls of functions not having input options – for example, viewing mes -
sage buf fers.
Y
ou do not have to enter a password to call a function of password level 0. If
you call a function that is assigned a higher level, the OP prompts you to en -
ter a password.
Levels 0 to 8 are assigned to functions of ascending importance. A password
level is assigned to a password by the superuser as part of his password ma -
nagement responsibilities.
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.
