摘要
对集装箱装卸桥仿真训练系统通信功能的实现方法进行了介绍。首先 ,采用VB6.0中的Winsock控件实现上位机之间的通信 ;再通过WindowsNT操作系统下的Cimplicity软件解决了上位机与PLC之间的通信问题 ;最后 ,采用DDE动态数据交换完成了VB和Cimplicity软件两种不同应用程序之间的数据传输。
In this paper, the communication function of simulation operating system for container crane is introduced. First, Winsock control of VB6.0 is used to conduct the communication between computers. Then, the communication between computer and PLC is realized by Cimplicity, which works under Windows NT operation system. Last, with the help of DDE (Dynamic Data Exchange), the data exchange between VB and Cimplicity is accomplished.
