<p>This invention relates to a CNC provided with an autonomous function as one of the constituent elements of an FA system, etc., using a host computer as the primary constituent. A CNC system (2A) comprises a CNC board (21), a PMC board (22) and a communication board (24), and plays the role of a machining cell in the FA system inclusive of a machine tool (23). The PMC board (22) receives a request indicated by the FA computer through a LAN (11) and the communication board (24), and executes suitable processing for the machine tool (23). It sends the processing result back to the FA computer through the communication board (24). Further, the PMC board (22) is provided with instruction means (22A). The instruction means (22A) makes suitable judgement in accordance with the condition of the machine tool (23) on the basis of various data sent from the machine tool (23), and requests suitable processings required to the FA computer, the PLC and other CNC system. The instruction means also makes suitable judgement on the basis of data from units other than itself, and requests necessary processings to the FA computer, the PLC and other CNC system.</p> |
