Hi raja8989!

• The Tick Count (ms) Function is a free running counter with 2^32 range, you can use it to benchmark parts of you code.
• The Tick Count Express VI allows you to configure ticks, milliseconds or microseconds - it ships with the FPGA, RT, or DSP modules.

Does that help?

can u please clearly explain with help of a example . i am not able to get a perfet clarity on this please

Thanks for getting back to me.  The following example shows the functionality of the function:

If you run the VI you will see the current value of the free running timer, and this will update every 100 milliseconds due to the "Wait on Next ms Multiple".

Another example can be found by following these steps; press Ctrl+H to display Context Help, mouse over the Tick Count (ms) function, select Detailed Help and navigate to Open Example.  This example gives a common use case for Tick Count (ms); timing how long some code takes to execute.

thanks a lot sir

now i came know what is tick count now exactly 

but when i runned ur code at first count this is displaying the value 24651619 .  why doesnt this start from zero ?

Per Help:

The base reference time (millisecond zero) is undefined. That is, you cannot convert millisecond timer value to a real-world time or date. Be careful when you use this function in comparisons because the value of the millisecond timer wraps from (2^32)–1 to 0.

I believe the initial zero occurs when the computer is powered up or rebooted. Give it a try.
