Hello!

I'm a bit confused by your question, but I'd say you can look into a couple different options: 

• If you don't want any other functions to run while the three second elapses, you can use the SyncWait or Delay function. The SyncWait is helpful if you're using it in a loop. The delay is helpful if you simply want to wait 3 seconds and move on. 
  SyncWait:: http://zone.ni.com/reference/en-XX/help/370051V-01/cvi/libref/cvisyncwait/
  Delay:: http://zone.ni.com/reference/en-XX/help/370051V-01/cvi/libref/cvidelay/
• If you need other code to operate during the three seconds, you can utilize timer event callbacks.

Hope this helps!

sory sir  yes my question was confusing. sir actualy i have a task in which i have to transmit some data to other source and in reply there will be response. after its response i will again transmit some data. one critical part of task is that if after 3 seconds if there is no reply from other end i have to stop transmit data. i m confused that how will i wait for 3 seconds and how would i know that there is no reply during 3 seconds

How are you transmitting your data and what are you sending it to? A lot of times there is timeout functionality built in to device communication APIs that we can use more easily!
