To protect the system against virus attacs or other system failures, it is
recommended to take the following measures:
n Either work without the CNC without Internet connection or assure
it is connected via a managed firewall.
n Be sure that there is no virus software already behind the firewall
in your intranet. Only then, it is save to use the internal ethernet
connection for data transfer.
n Use only virus free and verified USB memory sticks for data
transfer to the CNC control. Don't allow users to transfer data with
unverified USB memory sticks. If you are not sure whether you can
guarantee this, please consider the usage of a USB-Guardian soft-
ware (see http://www.trinit-soft.de/usb-waechter/).
In Windows 7, the FBWF is already part of the system. There is no
special graphical user interface ( GUI ) necessary. The FBWF interface
can be started in the taskbar, see Fig. 1.

Click on the little lock and the FBWF interface shows up the folling
window (Fig. 2).
After delivery, the FBWF is in state " enabled ". You must put it into the
state " disabled " if you want to install further software on the system
partition, or if you need to do other modifications there.
