| Abstract: | Lays special stress on the studying of application and implementation of free port communication in data transmission between PC and Siemens S7-200 PLC, and expounds the design ideas and implementation of PLC program and VB program in detail. According to comparing free port communication program with the similar software program of Siemens, the former increases highly the rate of data transmission between computer and S7-200 PLC, and running at a stable level. |
