<p>PURPOSE:To supply working program data to an NC device without interruption, by providing a function for transmitting the working program data cyclically, and a function for storing the data as a file. CONSTITUTION:A main memory 2 which transmits the working program data cyclically by a ring type buffer, and an auxiliary memory 5 for storing the working program data as a file are provided, and those memories are switched effectively by an instruction from a host computer system 7 corresponding to the function of the NC device 9 to be connected and the execution speed of the working program data in the NC device 9, and the working program data from the host computer system 7 is supplied to the NC device 9. In such a way, it is possible to supply the working program data to the NC device without interruption for a PTR start up request from the NC device even when the number of NC devices to be connected is increased.</p> |
