How to add a Pause button in this counter

[farhad11]

Hi Everyone,

Below I have attached a Labview VI of a counter. I want to set a "Pause" button that will stop counting until I press it again to resume. Can anyone help me in this regard?

I would be highly grateful to you.

Thanks in advance

Where does the counting take place?  What if you enclosed a key element of the count in a Case statement and wired a Boolean ("Pause"?) to its "selector"?

The boolean is used as a signal when the counter exceeds the limit. My problem is setting a "Pause " button in this program to pause and resume it. Thanks 🙂

This seems like a trivial first-day homework problem. 

You did not specify the full requirements, for example you also have a decrement case. Do you want to be able to pause that too? Should it always count up and down between zero and the limit forever?

Some comments to your code:

• You are dealing with integers, so there should be no orange anywhere. DO you know about numeric representation?
• The terminal of Boolean should not be hidden inside a case structure. Do you even need it?

Thanks for your reply. Yes, I am new in LabView progarmmimg. 

my requirement is to make a counter which counts continuously and it should have start, pause and stop buttons to perform their functions. No I don't need the Boolean inside the case structure.

Why would you need a start button? Just start the program in pause mode, then un-pause to start. You still have not explained the "count up" "count down" part. Is the user allowed to change the limit during the run?

There is no specific reason to add a Start button, just I want to know how to add those buttons to run a program. the count_down part I added to see whether I can do it or not. and yes user is allowed to use the counting limit.

Here's a quick draft (just counting up) to get you started. Now add all the other features. 😄
