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 .
