Timed structures are a new feature in LabVIEW 8. Two new timed structures are introduced, the Timed Sequence and the Timed Loop With Frames。 They help facilitate precise timing of operations in LabVIEW. Additionally, they enable the ability to have parallel loops running at different rates and ...
The timed loop is a little different in that it has more options under programmatic control. Besides adjusting the timing, the timed loop can run on a specific processor with a set priority. One approach for a processor with multiple cores is to group time-sensitive operations into one timed ...
如果您正在使用while loop進行讀取或寫入並且Clear Task在while loop後執行,請不要使用abort按鈕中止執行。改用連接到conditional terminal的停止按鈕。 情況2:使用已從被其他task預留的計數器對於需要兩個計數器的任何task,第二個計數器是根據連接到create channel vi的計數器保留的。計數器總是與相鄰的計數器配對,因此...
Thiscomponent of code shows how to use a sawtooth to generate a PWM signal. The example compares a sinewave to a trianglewaveform. The PWM signal generated isthe output of the comparator. Description This codehas been designed to run in a single-cycle timed loop, but also contains aclock ...

22、ata rapidly and the other loop processes the data at a much slower rate. implementing such a paradigm in other languages requires triggering an independent function thread for each process and developing logic to manage synchronization. through timed while loops, multiple independent while loops ...
回答= 在Timed Loop的Loop Configuration对话框中,对Timing Source选择use terminal,从All Functions-NI Measurement-DAQmx_-DAQmx Real-Time-DAQmax Timed Loop中选择DAQmx Create Timing Source.vi,设定要作为Timing Source的Counter和Frequency,然后把输出端timing source out连接到Timed Loop的source输入端,这样即可以...

Through timed While Loops, multiple independent While Loops can be easily synchronized to process at a desired period and phase relative to one another. LabVIEW allows invoking multiple instances of the same function with each maintaining its own data space. For instance, we could drag many ...
