Abstract:The trend of flexible manufacturing has led to the rapid development of distributed control system. And the importance of the control software of multiple nodes is increased prominently. The method that action sequence was separated from the programming of Graphical User Interface (GUI) was proposed. The text was used to describe the sequence of action, and edited and explained to create background action implementation program which was independent of the interface. Finally, by using the VI Scripting function of LabVIEW, the programming method is verified feasible through examples.
