Now there is another problem. The problem is after runnunig the program , the upper big loop runs and update write to measure file after 8 seconds. But the read from measurement file only reads the updated file only once not always when I push the subvis button.
I want to read the new data every time as it has been updated every 8 sec.

I am pretty sure RavensFan already told you the problem.  Your read is only done once due to it being outside of a loop.

Instead of reading the file, why don't you use something like a Producer/Consumer setup.  The idea is that you use a queue to send the new data to another loop for processing.

Is there any simple solution crossrulz?

Search the forum for "producer/consumer".

Click on the New..... link under the file menu.  You'll see templates there for producer/consumer.

Please tell me how to give complete access to LabVIEW of port.
The data I am receiving through port is very fast say after 3 seconds. But in LabVIEW, when I plot the waveforms, the waveforms become disturb and not accurate. Problem is in updating the previous data of 3000 array elements of last iteration. As it is slow. Please suggest me something.. Useful
