摘　　要：利用上位机来监控可编程控制器的通讯技术是现代工业控制中的常用技术。以PC机为上位机,PLC为下位机,针对三菱FX系列PLC与上位机之间的通讯协议,给出了利用VB6.0实现上位机与PLC串行通信的详细设计流程。试验结果表明,这种串行通信方法,传输数据准确、简单、移植性强。Serial communication between computer and PLC is often used in modem industrial control. Computer is the host, PI.,C is the slavery, specific to the communication protocol between Mitsubishi FX PLC and the host computer, the paper gives programming and process of serial communication between PLC and host computer by VB6.0. The result of test indicates that tiffs serial communication is accuracy for transferring data, simple and strong portability.
