An embedded SoftPLC programming system using VC++ development tools in Windows operating environment accomplished.The data structure is used to describe the softPLC ladder-diagram components,and a proposal of storaging and interfacing ladder-diagram collections is presented based on the object-oriented design idea.According to VC++ document/view structure,the software architecture of SoftPLC programming system is designed,which is divided into editing model,compile model and simulation model.And the corresponding algorithm is combined with.The principle of editing and complier scanning is introduced.This realization for low cost and efficient embedded SoftPLC programming system solutions puts forward a new thinking of the software design for software developers.
