Abstract
PURPOSE:To reduce the load of a microprocessor by connecting two numerical controllers to a communication adaptor of a cell-controller and outputted the NC data alternately from buffers of a shared memory via said communication adaptor so that those numerical controllers are controlled by the cell-controller. CONSTITUTION:The communication adaptors 17 and 18 are added to a circuit control type cell-controller 10 and four numerical controllers NC1-4 are con nected to both adaptors 17 and 18 via circuits CH1-4 respectively. The NC request signals received from controllers NC1-4 are sent to a main microprocessor MPU 11 via adaptors 17 and 18. The NC data stored in each buffer of a shared RAM 14 are read out alternately to adaptors 17 and 18 based on the program of a ROM 12. Then the adaptors 17 and 18 supply these NC data to controllers NC1-4 respectively. The cell-controller 10 controls the circuits CH1-4. Thus the load of the MPU 11 is reduced.
