摘要
介绍了FX系列PLC与PC的通信,从软、硬件角度分别给出了不同的解决方案。指出了编程口通信与计算机链接通信在通信参数配置和通信帧格式上的不同以及软元件地址的计算方法,同时列举了一个完整的PC与PLC通信实例的程序代码。
A number of problems on the communication between PLC of FX series and PC are analyzed and solutions to the problems in software and hardware are given.The differences between the programming port communication and computer-linking communication in parameter configuration and frame format are pointed out,and the method to calculate addresses of software switches is put forward.Also,by taking VB6.0 as an example,acommunication program code for PC is given.
