4.17.2 Factory setting of the Windows Firewall on the Siemens PC system
The Windows Firewall settings on your Siemens PC system are appropriately configured by
the PCU-Basesoftware for the use of SINUMERIK software and systems. For security reasons,
the Windows Firewall is activated in the company network and expanded by additional rules.
The Windows Firewall is deactivated in the system network. The descriptions in this chapter
therefore largely relate to the adaptation of the firewall settings for the company network.

Automatic network release of USB data storage media results in activation of the file and printer

The automatic network release of USB data storage media is activated in the default setting
of the NCU-Basesoftware. The file and printer release is then activated by Windows when a
USB data storage medium is connected.
