i.e,I need to increment the 1st loop say 50 times and i need to increment the 2nd loop say 100 times.
Task is, 1st loop needs to increment once and needs to wait until the 2nd loop increments to 100. once the 2nd loop increments to 100 it needs to reset to zero and the 1st loop increments once again and goes into the 2nd loop and it continues until the 1st loop no of iteration is finished.
Your question is very basic. You should spend some time with some of the learning resources. To learn more about LabVIEW it is recommended that you go through the tutorial(s) and look over the material in the NI Developer Zone's Learning Center which provides links to other materials and other tutorials. You can also take the online courses for free.
