Siemens provides automation and drive products with industrial security functions that 
support the secure operation of plants or machines. They are an important component in a 
holistic industrial security concept. With this in mind, our products undergo continuous 
development. We therefore recommend that you keep yourself informed with respect to our 
product updates. Please find further information and newsletters on this subject at:

To ensure the secure operation of a plant or machine it is also necessary to take suitable 
preventive action (e.g. cell protection concept) and to integrate the automation and drive 
components into a state-of-the-art holistic industrial security concept for the entire plant or 
machine. Any third-party products that may be in use must also be taken into account.
