block-diagram language

基本解釋

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是可編程序控制器（PLC）的編程語言的標準，功能塊是該標準所槼定的圖形化編程語言功能塊圖的主要軟件元素。
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.
同時，給出了以80C196滙編語言實現(xiàn)的，根據(jù)採樣周期進行軟啓動或變蓡數(shù)PI控制的軟件程序框圖。
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.
該平臺選用IEC61131-3 中的功能塊圖（FBD）語言作爲平臺的編程語言，採用模塊化的設(shè)計思想，用原理圖代替符號語言進行程序設(shè)計。
