| Abstract | This paper introduces Modbus-RTU Communication Protocol. Then, based on the analysis of the principle of communication and combining with an instance, the paper gives out a specific method to realize the serial port communication between computer and MCU C8051F020 in Kingview 6.55. Introduction With the continuous development of automation technology, the application of MCU has developed from independent single one to networking. And the distributed computer control system composed by PC and multiple MCUs is applied in many areas, which brings the advantage of MCU in actual time data processing and the advantage of PC in human-machine management and data management into full play. In the system like this, configuration software is often used to accomplish the development of PC monitoring program. Configuration software, which has the features of simple programming and short cycle time, solves the problem that control engineers lack the knowledge of computer while computer engineers lack the technology and experience of control and improve efficiency of automation engineering. MCU Hardware Circuit Design A. CPU Circuit Design C8051F020 is used as the micro-controller in slave computer, which is a fully integrated mixed-signal system-on-a-chip (SOC), with the MCS-51 instruction kernel, and has high speed pipeline structure. Fig. 1 is CPU circuit and P5.0 P5.3 connect 4 bit dip switch to set the device address, P5.4P5.7 connect 4 bit dip switch to choose the communication mode. Fig. 1 CPU Circuit TMS TCK TDI TDO /RST |
