基于MCGS组态软件的通用DDE“软通道”的研究与实现

Study of a General DDE "Soft-channel" Based on MCGS Configuration Software

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。

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.
