difference in time to get time period

[aisyah]

hello,

how can i use Get Time/Date to get the period between two time? For example, when i run the vi and press a button, the time is (4:05s). when i press the button again, the time is (4:48s). Then i should get the period (4:48-4:05 is 43 seconds). how do i do that? im using case strucutre, an i can only get the time when i press the button bot not the difference. any help or suggestions?

regards. aisyah

You get the time difference with a shift register and the subtract function. You wire the current time to the shift register on the right side of your while loop and to the subtract function and wire the left side of the shift register to the other input of the subtract function.

This is pretty basic LabVIEW programming. You should look at the on-line learning resources available at http://www.ni.com/academic/lv_training/how_learn_lv.htm
