Dear perumpadapu

Thank you for your post. Here is what I believe your problem to be; you run the code but when the true case is returned the second frame in the stacked sequence diagram does not execute properly.

I took a look at your code and the first thing I had to do was clean it up using the "Clean Up Diagram" button on your block diagram.  This made the data flow much easier to read so I was able to spot the problem in your code.  Because you used a stacked sequence (disabled) rather than a flat sequence (enabled) you hadn't wired the VISA resource name properly from the zeroth into the first frame.  Let me know if this code now works as you intend.

I also reccomend naming your controls and indicators either in the order in which they occur or in a more intuitive fashion - this makes it easier to debug.
