Abstract: A high-speed multi-task system which configures with an industrial personal computer and a numerical controller. The industrial personal computer handles the human-machine interface, visual function and main process control, while the numerical controller controls the movements of hardware and input/output. Conventional serial communication port RS-232 is employed for data transmission between the two sub-systems. The high-speed multi-task system of the present invention is built to work in a real-time extension environment to optimize the control and efficiency of a wire bonding system.
