摘要
本文以某配餐公司自动化立体仓库系统为例,系统采用西门子公司提供的PRODAVE数据链接库接口技术,用VB编写了客户端通信程序,实现了上位机与西门子S7-300PLC之间的以太网数据通信。实际应用表明,使用西门子PRODAVE数据链接库技术实现PC机对PLC数据的读写操作,不但数据传输速度快,而且实现起来简单方便。
The paper,taking the automated strorage of the certain meals company for example,used the technology of the PRODAVE data link library,and compiled the client communication program with VB,implemented the ethernet communication between the upper monitor and S7-300PLC.Passing through the actual operation,the System carried out to read and write operation for PLC date from PC computor with PRODAVE data link library simply and conveniently,and the speed of data transmission was quickly.
