12 Access Protection via Password and Keyswitch<br />
12.1 General<br />
Access protection<br />
system<br />
12-162<br />
S Protection level 0 offers the highest access authorization and protection<br />
level 7 the lowest.<br />
12.01<br />
S If a particular access right is assigned to a protection level, then the same<br />
right will be automatically available on all higher protection levels.<br />
S By the same token, an access right for a particular protection level can only<br />
be changed from a higher protection level.<br />
S The access rights on protection levels 0 to 3 are set as Siemens defaults.<br />
S Access authorization is set through scanning of the current keyswitch<br />
position and a comparison of password entries. In this case, a password<br />
entry overwrites the access rights associated with the keyswitch position.<br />
S Options can be saved on all protection levels, but option data can only be<br />
input on protection levels 0 and 1.<br />
S The access rights for protection levels 4 to 7 are merely suggested settings<br />
and can be altered by the machine manufacturer or end user.<br />
