1.3 Functions
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 for protection levels 0 to 3 are permanently assigned by Siemens and cannot be altered
(default).
• 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.
• Access rights for protection levels 4 to 7 are only suggestions and can be altered by the machine tool
manufacturer or end user.

available on the operator panel front when defining the password. Where a password consists of less than eight
