【摘要】 阐述了DDE技术的特点以及在MCGS组态软件中的具体应用,说明了采用DDE“软通道”方式与挂接的设备进行通信来获取系统数据的方式,提出了一种通过给出相关参数设置窗口,建立通用DDE“软通道”的模式,使应用者免去编写DDE应用程序的重复环节,具有良好的实际应用意义。更多还原

【Abstract】 This paper described the characteristics of the DDE technology and its application in MCGS configuration software.Furthermore.It introduced the communicating way to collect data from the connecting device by DDE "Soft-channel".The model for constructing a general DDE "Soft-channel" was put forward through a configurable window,in which relevant parameters can be set and the repeated programming step was avoided.It is showed that the model has a good practical significance.更多还原
