| Abstract: | The serial communication mechanism and characteristic of OMRON C200HE PLC based on the development of the monitoring engineering project of PVC compounding are introduced. The method and some key program of realizing communication between the upper computer and PLC with Mscomm in Delphi are mainly analyzed. Practical application shows this scheme is simple and utility. Also, the reliable performance of communication accords with the field requirement and the scheme has a reference value to develop the same kind of the control system. |
