在人机界面(HMI)的画面工程文件编制过程中离不开软件的修改和调试工作，一般情况下，带触摸功能的人机界面组态软件具有工程文件离线仿真功能， 不需要连接用户 PLC， 工程人员就可以比较方便的调试编制的 HMI 工程文件，直到工程文件满足设计要求。(In the man-machine interface (HMI) software to modify and debug the picture engineering documentation process, in general, with man-machine interface configuration software with touch function project file off-line simulation function, users do not need to connect PLC, HMI project file project staff can be more convenient for debugging, until the project meet the requirements of the design documents.)
