标准摘要
[中文适用范围]: “本国际标准定义了 GRAFCET1 规范语言,用于控制系统顺序部分行为的功能描述。本标准规定了该语言@的图形表示及其解释的符号和规则。本标准具有已为工业应用的自动化生产系统做好了准备。但是,不排除任何特定的应用领域。使用 GRAFCET 的规范开发方法超出了本标准的范围。一种方法是例如“SFC 语言” “在 IEC 61131-3@ 中指定,它定义了一组可编程控制器的编程语言。 注:有关 IEC 60848 与实现语言(例如 IEC 61131-3 的 SFC)之间关系的更多信息,请参阅附录 C。 1 GRAFCET:GRAphe Fonctionnel de Commande Etape 过渡。” [外文原描述]: IEC 60848:2013 defines the GRAFCET specification language for the functional description of the behaviour of the sequential part of a control system. It specifies the symbols and rules for the graphical representation of this language, as well as for its interpretation and has been prepared for automated production systems of industrial applications. This third edition cancels and replaces the second edition published in 2002 and constitutes a global technical revision with the extended definition of the concept of variables introducing: internal variable, input variable and output variable.
