| Abstract: | In this paper, an embedded soft PLC development system has been designed and devel- oped based on VC ＋ ＋ development environment, focusing on completion of the key technologies of soft PLC development system： ladder editing and compiling. The ladder editor includes ladder diagram edi- ting, the establishment of the storage structure of the diagram＇s attribute and the storage of corresponding files. Based on the binary tree and forest data structure, stack data structure and XML, we developed a ladder program compiler to research and achieve the transformation method from ladder diagram logic solved results to the target machine codes. |
