All the DAQ and control processes are in a while loop frame designed in the block diagram panel, ... How do I stop a while loop with a wait ms timer before it is finished its cycle? Review an example of code using this function here: For better performance, consider using a Producer/Consumer architecture, QMH, or Dynamic Events. Controlling the time between loop iterations and being able to measure the time between events are both very important tasks in any data acquisition activity. Thus, a loop with that contains one on these VIs will not advance to the next iteration until this function finishes waiting for the specified time. These are specifically designed for timing tasks. Therefore, this function does not complete execution until the specified time has elapsed. In the example below, the CODE will execute in 5 ms, and the loop will not iterate until a multiple of 20 ms is reached on the system clock. Wait ms Timer Multiple returning inaccurate timer value, 4. What are Quick Drop Control-Key Shortcuts. When you use the Wait (ms) timing VI inside a While Loop, you allow the processor to execute other tasks in its queue, before coming back to check on your While Loop again.

How do I plot multiple signals on a waveform chart? Previous page. It can be inserted into an error wire to introduce a delay at a specific point in the data flow of a VI. Unlike a For Loop, While Loop execution does not depend on iteration count; thus, a While Loop executes indefinitely if the condition never occurs. This malleable VI, introduced in LabVIEW 2020, can be inserted into any wire to introduce a delay at a specific point in the data flow of the VI. Waits the specified number of milliseconds and returns the value of the millisecond timer. 06-02-2009 02:24 AM. Enter your email address to subscribe to this blog and receive notifications of new posts by email. Next page. However, because the while structure is do-while, the termination condition is checked after at least one iteration has been . You can specify a target time to wait and poll this VI to determine when the elapsed time has expired. How to use LabVIEW on WKU campus computers? When the VI runs, the code inside the While Loop executes, and then the terminal condition is evaluated. Returns the value of the millisecond timer. As you can see from this example, the loop period may be less than 20ms in the first iteration, but subsequent iterations will be the desired time. Collaborate with other users in our discussion forums. These loops are used to control repetitive operations.
