摘要
介绍了一种利用Snap7的C++协议库编写以太网S7客户端的方法。首先介绍了Snap7客户端的建立、连接服务器及读写数据的方法,然后通过该方法编写了基于Qt及MFC的以太网客户端,并通过PLC现场项目测试验证了编程的正确性,具有一定的借鉴意义。
This paper introduces a method of using Snap7's C++ protocol library to write Ethernet S7 client. Firstly, the establishment of Snap7 client, the method of connecting server and reading and writing data are introduced. Then, the Ethernet client based on Qt and MFC is compiled by this method.
