This documentation only describes the functionality of the standard version. Extensions or
changes made by the machine tool manufacturer are documented by the machine tool

Other functions not described in this documentation might be executable in the controller. This
does not, however, represent an obligation to supply such functions with a new controller or
when servicing.
Further, for the sake of simplicity, this documentation does not contain all detailed information
about all types of the product and cannot cover every conceivable case of installation, operation
or maintenance.
Note regarding the General Data Protection Regulation
Siemens observes standard data protection principles, in particular the principle of privacy by
design. That means that
this product does not process / store any personal data, only technical functional data (e.g. time
stamps). If a user links this data with other data (e.g. a shift schedule) or stores personal data on
the same storage medium (e.g. hard drive) and thus establishes a link to a person or persons,
then the user is responsible for ensuring compliance with the relevant data protection
regulations.
