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 ProTool, 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 effect on the course of the process; these are nor-
mally calls of functions not having input options – for example, viewing mes-
sage buffers.
You 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.
