Elapsed Time

[inuyasha84]

Hi guys I'm using the Elapsed Time to set a wait and to have, at the same time, the chance to stop the waiting.

The problem is that if for example I set wait for 1 minute the first time everything works fine, but when I repeat the same operation (my VI is a state machine so I can put it in an idle state) something goes wrong...I tried to debug but I'm sure that the problem is the Elapsed Time for two reasons: the first is that I have replaced it with Wait (ms) Function and it works properly everytime I want, the second is that I put an indicator on the Elapsed time (s) and the first time I see that it count/wait from 0  to 1sec while the second time in automatic it goes to 5,46 without any countdown.

I hope you can help me because this thing is driving me crazy.

please post your VI and not a image of it.....the problem might be in how to reset the timer input to count properly or to hold it.

hi sorry for the delay... attached there is the VI..

the problem is in the Max Hold&Peak table as shown in the immage:

Hi inuyasha84,

I believe you need to reset the elapsed time express VI in order to make it start counting at 0 again.

If you hover the mouse over the VI, you can see that there is an input node for you to reset the function.

May i ask why you want to do this when you can use wait(ms) function or time delay function?

Hope this help

Best regards,

I tried already with the reset and the error is always there. When it iterates the second time it gives in exit a strange number... it doesn't count from 0 to the value that I set.

Bytheway I need to stop the VI because if for example I did an error in the setup and I have the wait (ms) function setted at 1h I must wait until it finishes (The idea is to do an .exe of this VI).

Hi inuyasha84,

May i know how you reset the express VI?

I attached here a simple VI to show how you can reset the elapsed time.

Hi Tuitui, could you do a print? because my labview version is the 2012 and it gives me an error.

Thank you

Hi,

I attached again the VI in 2012 version

I also attached the snapshot and the snippet in case you cannot open the VI

Best regards,

Hi again, I tried your method but it doesn't work. At this point I don't think that it is a problem of reset.  In the meanwhile I was waiting for your reply, I tried a new approach on the problem. I did a new VI with less function and now it works properly... so there should  be something in my main VI that creates problem....

attached there is the example I did... it is part of the code I use in the principal VI on which I'm working on.

I don't see where the error is....uff

Hi inuyasha84,

Atleast you know that the problem is not from the elapsed time.

I barely can help you in this case as this is more of logic wise and i hardly understand what you are trying to do.

If you could explain more on the whole application, i might be able to help you.

Hope you can find out where the problem is
