Hello, I'm looking for the best way to retrieve data from a CNC to a PC (by data, I mean "is the machine tool working ?" and such simple things) in order to develop an application which would use it. I've already learned that in the most common cases there is first a converter, from the cnc protocol to a standard bus (that I don't know for the moment), and then, a second converter, from the bus to the PC. My questions are : - Is it correct ? If not, what are the other possibilities ? - What kind of bus should I use ?
