Hi Claudia

Now again - as Novatron mentioned you have to change the loop condition. Now you have it "continue while true" which is why it is stopped immediately - the stop button is false. Change it to "stop if true" as you can see on the picture. Just right click on the condition and change it.

And then it should work - on my pc it worked after this modification.

Hope this helps.

I know, but this options aren't there by me. Is it possible, that Labview 5.1 doesn't have this opportunity?

Or do you know why I can't see it?????

[becktho]

Maybe LV5.1 doesn't have it. So the easiest thing you can do is to insert a logical "not" which you should find on the boolean palette.

In this case the false-value of the button will change to true which matches the condition to loop on.

Hope this helps.

Do you mean it this way?

this way it only change between 0 and 1 again.

[becktho]

Yes that's it.

But it works without any problem.

If you push switch (off -> on) the counter is increased. If you push it again (on -> off) nothing happens. Now it starts again (off -> on = +1, on-> off = nothing).

Just push switch several times.

It works!!!!!!!!! Thank you so much!!!!!!

Is there a opportunity to count all the events in an other counter and when you open the next time this programm somewhere this counter carry on with the last value.

You can use this vi as a sub-vi an pass the last value of the counter (just wire an indicator to the right shift register). The initial value of the left shift register should be replace with a control. So you can start the counter with another value.

I just started reading this thread.  The option to choose between the Continue While True and Stop When True in a while loop is not available in LV 5.1.  If you click on the continue icon, nothing will happen.  This option was introduced in LV6.  LV5.1 users have to invert the boolean wired to the continue terminal to stop the loop when true.  Sorry I didn't respond to this earlier, much too busy at work nowadays.

Hi again!

Is there any change to do the "stop" out of the loop?

Thank you!
