Abstract :
This paper mainly introduces the communication between computer and S7-200PLC of Siemens, in which host computer (PC) adopts MSComm control in VB6.0, a visual programming language, to implement the data communication between console computer (S7-200 PLC) and computer, based on free port communication protocol. Communication protocol format is user-defined in this paper, so huge data communication in real time can be implemented conveniently, and the demand for the amount of data in a practical system can be met.
