Question

Problem #4 Below is a fairly common VI that can be utilized by many more complicated programs you could build in LabVIEW. The other case is Reset. You can assume that each time this VI runs, the State Variables out' from the previous iteration are passed to the 'State Variables in'. In your own words, what is occurring when this VI is run? What do you think is occurring in the 'Reset case? erence for Bundle by Name tate Variables out Elapsed Time lapsed Time 823 State Variables in Elapsed Time Command

Answer 1

For LabView, the given timing functions have the following meaning:

1) Time stamp: It is a data type which views, stores and uses high precision absolute time. It can store up to 18 digits in whole second and it can store up to 19 digits in fractions of a second.

2) Elapsed time: The time that has elapsed since the specified time.

3) Get Date/ Time in seconds: It converts time stamp value to the date and time string in the time zone for the particular computer’s time zone.

In the given VI:

1) When this VI is run: The block acts like an up-counter starting from zero (reset value). i.e., the block counts as 0 --> 1 --> 2 --> 3 --> and so on.

2) In the reset case: The up-counter is restarted, i.e. , the up-counter’s present state becomes zero. So when it starts counting again, it starts from the reset value (which in this case is zero).

Hope its helps. All the best.
