Access protection
|
|
|
|
Function
- Access to programs, data and functions is protected in a user-oriented hierarchical system of 7 access levels.
- Protection level 1 has the highest, protection level 7 the lowest access rights. A higher protection level automatically includes all protection levels below it.
- Access rights for the protection levels 1 to 3 are set by Siemens by default. Entry of a password will overwrite the keyswitch setting.
