Multi-level security concept
A multi-level security concept to regulate access rights is available in the form of password
levels and keyswitch settings.
Protection level

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.
