Note on IT security
Siemens offers IT security mechanisms for its automation and drive product portfolio in order
to support the safe operation of the plant/machine. We recommend that you inform yourself
regularly on the IT security developments regarding your products. You can find information
on this on the Internet (http://support.automation.siemens.com).
You can register for a product-specific newsletter here.
For the safe operation of a plant/machine, however, it is also necessary to integrate the
automation components into an overall IT security concept for the entire plant/machine,
which corresponds to the state-of-the-art IT technology. You can find information on this on
the Internet (http://www.siemens.com/industrialsecurity).
Products used from other manufacturers should also be taken into account here.
