while loop synchronous operation

[Nepla]

I have created a vi where it has to acqire data over ethernet parallely (using two while loop) and display those data . but i m unable to do so because both the loops are not running simultaneously . Somebody please help me out . VI is attached

Of course they don't run in parallel. You don't understand the basic paradigm of LabVIEW - dataflow. You've forced the top loop to execute after the bottom loop because you wired the controls in the bottom loop to the top loop.

Thanx a lot !  How to control both the loop with single control action (STOP Button )

[Dennis_Knutson]

An easy way is to simply use a local variable. The mechanical action cannot be latching though so you would use a another write after the loop finishes to set the value back to false. There are other, more sophisticated ways without using a local but this will get you going.
