Protection level concept
Protection levels
In SINUMERIK 840D there is a protection level concept to enable data areas.
Protection levels range from 0 to 7, 0 representing the highest and 7 the lowest
level.

Protection level 4 (key switch position 3) and higher is required to display
machine data.
The appropriate protection level must generally be enabled by means of pass-
word "EVENING" to start up the system.
Table 6-2
Protection levels
Protection levels 0 to 3 require a password to be entered. The password for
0–3
level 0 provides access to all data areas. For protection levels 1 to 3, default
passwords are defined when the system is powered up in start-up mode (NCK
start-up switch in position 1). To guarantee secure access, these default pass-
words MUST be changed once they have been activated. If, for example, the
passwords have been forgotten, then the system must be reinitialized (NCK
general reset). This resets all passwords to the standard of this software
version.
