<p>PURPOSE:To shorten input and output time of the data and to decrease a load of the host computer by dividing plural NC devices and connecting them to one host computer, which stores many NC programs, for every group. CONSTITUTION:Plural NC devices 201 are connected to a host computer 101 composed of processors 101a, ROM101b, RAM101c, etc. At this time, the plural NC devices 201 form one group GA-GC by some NC devices and are connected through an adapter 301 composed of a microcomputer installed for every respective group to the host computer 101 respectively. The adapter 301 is equipped with a buffer part BFR to store NC data and a control part CNT to monitor an effective NC data quantity stored in this, and monitors, etc. Thus, when the effective NC data quantity becomes a constant value or below, the control part CNT requires the NC data of the NC devices 201 corresponding to the buffer part BFR, to the host computer 101.</p> |
