| Abstract: | The design of a system that the visual editing of PLC ladder diagram and generating of instruct list is proposed,aiming at the limitation and lack of the algorithm of binary tree structure,a new algorithm to convert ladder diagram to instruction list is presented.Through an example describe the scanning process of ladder diagram convert to logic tree as well as traversal algorithm of logic tree,experimental result shows the feasibility of this algorithm. |
