You have a greedy while loop.  There is nothing there throttling the speed of the loop.

Where are you getting a timeout error?  Using VISA writes should not give you a timeout error.

What are you really trying to do with your VI?

(PS, the word "I" is always capitalized)

When we pressed a switch on runtime at that time it can not display  on another PC,but it can display after time out error, and then it generate output,and after press on continu button,then and the only we able to get another out put,

we use usb to rs232 converter,is this causis by that?

What does "switch on runtime" mean?  Specifically what do you mean by the term "runtime"?

Where are you getting the timeout error?  You are now talking about another PC.  That is an important detail that you left out of your original story.  Is that where you are getting the timeout error?

Fill in the rest of the details.  That is why I asked "what are you really trying to do."

I don't like wasting time playing guessing games as we try to coax the details out of you.  The quicker you can give us the important details of your problem, the easier it is to help you solve the problem.

Hi pareshsabhad

                               I modified your VI with error out. Run this VI and let us know the error outs. 

You are new here as i can see through your number of posts. Lets make a practice of some tips before you post your problem (Not hard and fast rules).

1. Always upload your VI.

2. What input you are giving and what corresponsing output you are expecting.

3. Clarify the problem. if possible then use bold letters for that.

4. What error and where exactly you are getting that let us know.

5. Upload the image of that if possible

Dont worry we will deal with it.
