WebApr 15, 2024 · LabVIEW功能全局变量功能全局变量（FGV）是一种常用的设计模式。FGV是一个非可重入VI，具有迭代一次的while循环，并具有未初始化的移位寄存器。此构造的目的是在对FGV的连续调用之间保留数据。可以使用FGV代替全局变量，主要有两个原因：更改存储值时，可以执行其他任务。 WebFeb 9, 2006 · One way is to detect the positive going zero crossings and count those. See the attached example in which I extracted your sine generator and added the counter. Note that it adds a cycle as soon as the zero crossing is detected (beginning of cycle), not when the cycle is completed. You can modify it to meet your needs. WebIf, when a cycle overflow occurs, you want to receive a warning rather than an error, set the DAQmx Real-Time»Convert Late Errors to Warnings property to True. Hardware-timed counter operations have no conversion period similar to that of multiplexed analog input.
