描述使用MELSAP3功能用SFC程序给MELSEC-Q系列高性能型号QCPU（Q模式）(简称为高性能型号QCPU)和MELSEC-QnA系列CPU(简称为QnACPU)编程的规格、功能、指令和编程步骤。
“SFC”是“顺控功能图”的缩写，表示控制运行顺序分成一系列步的程序格式，能够清晰地表使用MELSEC-Q系列、MELSEC-L系列可编程控制器。ST语言是指，对于打开·控制中的逻辑表示方式所规定的国际标准IEC61131-3中定义的语言。 描述用于在QCPU(Q 模式)、QnACPU 和Q2AS(H)CPU(S1) 上进行编程的公共指令。公共指令是除了AJ71QC24 和AJ71PT32-S3 的特殊功能模块用指令、用于AD57 的指令、用于PID 控制指令、用于SFC 和ST 的指令之外的其它所有指令。
