Five standardized programming languages:sequential function chart(SFC),ladder diagram(LD),function block diagram(FBD)three graphical languages and instruction list(IL),structured text(ST)two text languages.

Sequential function diagram is a flow chart of structural block control program.Ladder diagram and function block diagram are graphical languages.Instruction list and structured text are two text languages.The application of ladder diagram is intuitive and can be converted to instruction list.

五种标准化编程语言：顺序功能图（SFC）、梯形图（LD）、功能模块图（FBD）三种图形化语言和指令表（IL）、结构文本（ST）两种文本语言。

顺序功能图是一种结构块控制程序流程图，梯形图和功能模块图是图形化语言，指令表、结构文本两种文本语言，梯形图的应用直观，与指令表可以相互转换。
