Important information
Change firmware settings
The firmware settings are preset for working with the included software. You should only
change the default firmware settings if technical changes to your device require other
settings.
NOTICE
Malfunctions can occur with running software CPU
If a PC firmware/BIOS update is being performed while a SIMATIC software controller, such
as a SIMATIC WinAC, is running, the software CPU can malfunction, resulting in
communication interruptions or failures, among other things. Other actions that put a
heavy load on the PC hardware, for example, running hardware tests such as benchmarks,
can result in malfunctions of the software CPU.
Do not run a firmware/BIOS update or other actions that would put a heavy load on the
hardware during operation of a software CPU.
Switch the software CPU to "STOP" before you run a firmware/BIOS update or perform other
critical actions.
Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens' products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be connected
to an enterprise network or the internet if and to the extent such a connection is necessary
and only when appropriate security measures (e.g. firewalls and/or network segmentation)
are in place.
For additional information on industrial security measures that may be implemented, please
visit (http://www.siemens.com/industrialsecurity).
Siemens' products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends that product updates are applied as soon as they are
available and that the latest product versions are used. Use of product versions that are no
longer supported, and failure to apply the latest updates may increase customers' exposure to
cyber threats.
