The HostLink communication protocol of OMRON CS series PLC is introduced in this paper. The method for realizing the communication between PLC and the host computer is presented by means of c# and a control named SerialPort in Visual Studio 2005. The communacation procedure and program is also introduced in detail in the paper. This method ensures that the communica-tion is real-time and accurate. Through reading and writing of the host computer from or to the PLC, automatic collection of field data is realized, and the device can be monitored and controlled effectively. The serial communication software is proved to be reli-able and stable through the successful application in actual project.
