ladder logic diagram

基本解释

The control software adopts 984 Ladder Diagram. Its complicated logic is difficult to understand, and it doesn't accord with IEC programming language.
空分装置控制系统采用非IEC标准的984梯形图编程，并且梯形图程序复杂，故障查找困难。
The programmable controller uses the ladder diagram and auxiliary identifier to realize control logic mainly, it reflects the flexible characteristic of PLC controll outstandingly .
可编程控制器主要应用梯形图与助记符语言实现控制逻辑，使PLC控制灵活的特点得到突出体现。
Transformation algorithm between the ladder diagram and the statement list based on the AOV diagraph and the cause and effect diagraph for programmable logic controller(PLC) systems is proposed.
结合AOV图与因果图提出了一种新的梯形图与语句表双向转换算法。
