| Abstract: | Assembly language is machine -oriented,and used todevelop high efficient device driver. The methods of cornmunication between PCs and industrial control computers,is discussed in this paper. In which physical connection and programming is stated in details. The communication program with assembly language is short executable code and high speed in running. It proves valuable in studying and developing the distributed control system. |
