<p>PURPOSE:To attain the shared management of NC programs for respective numerical controller by providing each of plural numerical controllers with a communication control means and an NC program area and mutually connecting these controllers through a communication line. CONSTITUTION:The numerical controller 100 is connected to the communication line 900 by a bus format in order to execute communication control between respective numerical controllers through a communication control means 160. An NC program or the like is stored in a memory 110 and a memory buffer for temporarily storing data or the like is built in the memory 110. The means 160 always monitors the line 900 and transmits/receives data to/from the other numerical controller based upon commands outputted from a display control means 130, an editing means 140 and an execution means 150. In order to suppress the occupied time of the line 900, the commands and transmitted/received data are temporarily stored in a buffer 161. Consequently, the NC program areas of plural numerical controllers requiring no host CPU can be managed.</p> |
