Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, solutions, machines, equipment and/or networks. They are
important components in a holistic industrial security concept. With this in mind, Siemens'
products and solutions undergo continuous development. Siemens recommends strongly
that you regularly check for product updates.
For the secure operation of Siemens products and solutions, it is necessary to take suitable
preventive action (e.g. cell protection concept) and integrate each component into a holistic,
state-of-the-art industrial security concept. Third-party products that may be in use should
also be considered. You can find more information about industrial security on the Internet
(http://www.siemens.com/industrialsecurity).
To stay informed about product updates as they occur, sign up for a product-specific
newsletter. You can find more information on the Internet
