block-diagram language

基本解释

Aiming at standard IEC61131-3 Function Block Diagram (FBD) programming language, a modeling method of PLC program based on state space model is proposed in this paper.
IEC 61131-3是可编程序控制器（PLC）的编程语言的标准，功能块是该标准所规定的图形化编程语言功能块图的主要软件元素。
The block diagram of the system software that the soft start-up and the variable parameters PI control is realized with assemble language 80C196 according with sampling period is given out.
同时，给出了以80C196汇编语言实现的，根据采样周期进行软启动或变参数PI控制的软件程序框图。
The platform selects the function block diagram(FBD) language in IEC61131-3 as the programming language, adopts modularized design idea, and replaces symbolic language with principle chart to program.
该平台选用IEC61131-3 中的功能块图（FBD）语言作为平台的编程语言，采用模块化的设计思想，用原理图代替符号语言进行程序设计。
