Trusted Platform Module (TPM)

Depending on the ordered configuration of your device, a Trusted Platform Module according
to Standard TPM V2.0 may be available. The Trusted Platform Module is a chip that
enhances your device with security functions. It provides an improved protection from
manipulation of the PC.
NOTICE
Import restrictions for the Trusted Platform Module
Use of the Trusted Platform Module is subject to legal restrictions in some countries and is
not permitted there.
• Be sure to observe the respective import restrictions of the country in which the device
Activate the Trusted Platform Module
You can find information on activating the Trusted Platform Module in the detailed
firmware/BIOS description, see "Important instructions and manuals for operating the device
(Page 11)".

Buffer memory NVRAM (optional)

For applications to store data following a power failure, motherboards feature battery-
buffered NVRAM. If the supply voltage fails for more than 20 ms for the AC power supply or
more than 5 ms for the DC power supply, then you will be informed about this situation by
the NAU signal.
At least 10 ms is available to copy the data to the buffered RAM. During this time, 128 KB
can be saved with a full load and even more with a smaller configuration, in other words, a
lesser load. A memory window with a maximum size of of 512 KB can be displayed by
means of a PCI address register. The base address is initialized by the BIOS.
A corresponding function is implemented there for using the NVRAM under Soft PLC.

The device can be operated without a monitor and keyboard. The device startup is
guaranteed without these peripherals. A USB keyboard and mouse and an analog CRT
monitor can be later connected for diagnostics.
