摘要
以Python与Rslogix5000+PLC通讯为例,详细介绍了OPC通信和直接通信的方案设计、软硬件环境搭建及程序编写。同时对两种方案进行了比较,认为直接通讯方案更符合未来发展趋势。
Taking the communication between Python and rslogix5000+PLC as an example,this paper introduced the design of OPC communication and Direct communication,the construction of software and hardware environment and the programming.At the same time,the two schemes are compared,and the direct communication scheme is in accordance with the future development.
