Virus scanners

HEIDENHAIN found that virus scanners can negatively affect the

behavior of the NC control.

Possible negative effects are feed rate drops or system crashes,

for example. Such negative effects are unacceptable in numerical

controls for machine tools. HEIDENHAIN therefore does not offer a

virus scanner for the control and does not recommend using a virus

The control provides the following alternatives:

Locking from external access

Monitoring of TCP and UDP ports

If properly configured, these options ensure extremely effective

protection for the data of the control.

If you insist on using a virus scanner, you must operate the control

in a protected network (with a gateway and a virus scanner). The

subsequent installation of a virus scanner is not possible.
