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. For more information about industrial security, visit http://www.siemens.com/
