Delays for a certain time interval before the output data dependence becomes valid. RT Module The Wait Express VI waits the specified count time and then returns the value of a free running counter.

If you do not have the FPGA, RT, or DSP modules, you can use the Wait (ms) function instead.

Note  RT Module, Windows When the Wait Express VI runs, it sleeps and blocks the execution of the thread of the calling VI. Any code running in parallel in the calling VI or any VIs running in the same execution system thread are unable to execute during the time that the Wait Express VI sleeps.

Parameter	Description
Counter Units	Unit of time the VI uses for the counter. Note  Windows The Windows operating system supports only millisecond resolution. If you select a µSec or Tick resolution under Windows, the VI does not provide exact timing and instead provides an approximation that averages to the requested time over the course of the timing interval. Windows does not support resolutions under one millisecond and rounds them up to one millisecond. Ticks—Sets the counter units to a single clock cycle, the length of which is determined by the clock rate for which the VI is compiled. µSec—Sets the counter units to microseconds. mSec—Sets the counter units to milliseconds.
Size of Internal Counter	Specifies the maximum time a timer can track. To save space on the FPGA, use the smallest Size of Internal Counter possible for the FPGA VI.

Count	The time spent in the component.

Parameter	Description
Tick Count	Returns the value of a free running counter at the time the VI wakes up. A free running counter rolls over when the counter reaches the maximum of Size of Internal Counter specified in the configuration dialog box.
