Access authorization

Access authorization
Access to programs, data and functions is useroriented and controlled via eight hierarchical
protection levels. These are subdivided into:
● Four password levels for Siemens, machine manufacturer (2x) and end user
● Four protection levels for end users (interface signals V2600 0000.4 to .7)
This provides a multilevel safety concept for controlling access rights.
