第2章 程序结构图2-1 While循环的位置第2章 程序结构建立While循环的方法是,在函数模板中的Structures子模板中选择While循环对象,把鼠标移动到框图上,鼠标指针变成缩小的While循环的样子,按下左键拖拽出虚线框,松开鼠标左键后,While循环放置完毕。While循环有两个固定的数据端子,分别是重复端子(Loop Iteration)和条件...
LabVIEW While Loop flowchart Unlike a For Loop, While Loop execution does not depend on iteration count; thus, a While Loop executes indefinitely if the condition never occurs. For more information on what a While Loop is, including its components and configuration options, look into While Loops...
Normally when a loop, such as a while loop, finishes executing one iteration, it immediately begins running the next. However, it is often beneficial to control how often a loop executes as this will allow the processor to complete other tasks such as up

While循环有两个固定的数据端子,分别是重复端子(LoopIteration)和条件端子(LoopCondition)。重复端子表示当前循环的次数,初始值是0。条件端子连接一个布尔型变量,指示循环退出或循环继续的条件。具体的循环继续的条件有两种,即StopifTrue和ContinueifTrue,具体采用哪种方式可在条件端子上弹出的快捷菜单里指定,也可以...
