delay loop problem

[KenLabView]

I have a small problem with adding a delay to a for loop.I didn attach the whole coding but just a simple example just so u guys can understand what i am asking here..as u see ive introduced a 2000 msec delay in for loop..but as soon as i click run in this case the tank value changes to 3 but i want the calue to show 3 only after 2sec(2000msec).. how do i achieve this?

Labview executes code in parallel. There is nothing to prevent the tank to be immediately updated.

[KenLabView]

is it possible to add a reset button so that tank can be set to zero b4 starting the program since the previouse value at stop of execution still shows.

Controlling when the indicator gets updated is just a matter of correct dataflow. Setting the indicator to a default value when the VI starts requires a local variable.

These are LabVIEW basics and you can use the resources at http://www.ni.com/academic/lv_training/how_learn_lv.htm to start.

You could also delay the start of the loop by 2000ms. There are many possibilities, here are two more. 🙂 The rest of the code will dictate the best way to do this.

The secret is in dataflow and data dependency. Use execution highlighting to get a better understanding of it all. 😄
