| Abstract: | This paper introduces the serial communication protocol between PLC and the computer under free port mode of S7-200PLC. Firstly the format of computer sending and PLC feedback information is described, and then a part of program design of LabVIEW8.5 software platform and PLC we given. Finally an example of detection system, designed with a combination of LabVIEW8.5 and PLC is given. The experimental results show that the communication between the computer and PLC is good, and the detection function is achieved. |
