4.1 Access protection using password and keylock switch
Access levels for enabling data areas are implemented in the SINUMERIK 840D sl.
These are subdivided into:
• 4 password levels for Siemens, machine manufacturer and end user.
• 4 keyswitch positions for end user.
This provides a multilevel safety concept for controlling access rights.
Access rights
• 0 to 3 are locked by means of a password and
• 4 to 7 by means of keyswitch positions.
Table 4-1 Protection level concept

Access features
• Protection level 0 provides the greatest number of access rights,
protection level 7 the least.
• If certain access rights are granted to a protection level, these protection
rights automatically apply to any higher protection levels.
• Conversely, protection rights for a certain protection level can only be
altered from a higher protection level.
• Access rights on protection levels 0 to 3 are set as Siemens defaults.
• Access rights can be set by querying the current keyswitch positions and
comparing the passwords entered. When a password is entered it
overwrites the access rights of the keyswitch position.
• Options can be protected on each protection level. However, option data
can only be entered in protection levels 0 and 1.
