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.

| Parameter | Description | ||
|---|---|---|---|
| Counter Units | Unit of time the VI uses for the counter.

| 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. |
| Parameter | Description |
|---|---|
| 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. |
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. |
