基于PLC实现对步进电机的远程控制

In this paper, it expounds how to achieve the remote control of step motor based on PLC by means of optical fiber transmission, and gives the design of hardware and software about that Industrial Personal Computer (IPC) sends the control commands to PLC for accomplishing position control, redirection control and speed control of the step motor. At the same time, the paper demonstrates the design is applied to the control system of continuously loading of metal coating specimens.
