Centering on the THSMS-C type network programmable controller in the Experimental Center of school of automation,this paper realized the communication between Siemens S7-200 PLC and the host computer based on VB6 . 0 . The objectives are to enhance the real-time monitoring function and to improve the experimental performance of PLC control system. On the one hand,the controlled interface of man-machine is designed by VB6. 0,which can in-put parameters in need and display real-time output results. And the serial communication ActiveX controller MSComm is provided by VB6 . 0 ,using the free port communication protocol to achieve communications between PLC and PC,then PC stores and processes the experiment data timely. This paper applies experiments to prove the correct-ness of the study. The results show that the design will get good monitoring and control function,which has advantages such as economy,reliability,flexibility,real-time performance and so on.
