Re: What are the rest doing?
@keithpeter - When I worked at Hein-Werner - we kept the entire plant off line because we knew it was hopeless to protect the network. At least managment was smart enough to realize that. You could only download a program for a CNC by manual switching and only for the seconds it took to load each program. then switch off. This network was completely isolated - everything else was 'sneaker net'. One good thing about it was, you never had to worry about a patch blowing up your programming; so it was darn well worth it, in my best estimation.
Of course there was no Windows involved just G code and some paper tape conversions.
