d_2014,

If you want to prevent the counter from being output, I think you have two choices.

1) Commit the counter task, and use an empty string for the OutputTerm.

2) Use the DAQmx Tristate Output Terminal.vi once the counter task is done.

It appears as though you have attempted option 1, however you'd need to use the DAQmx Control Task VI to commit this setting (I think). 

Hope that helps,

Dan

hie Mcdan...

i tried this but i think i am not using this in proper way. i tried empty string concept but it didnt give me result. if possible can u give me example vi which can be used in my above Vi.

thanks & Regards,

Attached is my example (it provides both methods discussed).  I used a text panel with the same device to count edges on PFI0.  Methodology:

1) Run Example and export to PFI0.

2) Stop Example

3) Change output terminal to PFI1

4) Run Example

Notes:

For Method 1, I would continue to see counts until I stopped and started the test panel.  Without digging it to deeply it appears as though the route is not released until the edge count timer is stopped.  Stopping and starting this counter stopped the counter from seeing edges on PFI0.

For Method 2, I stopped seeing edges immediately after stopping the CO Pulse Freq task.

Hope that helps,
Dan

Dear Mac,    

      I  ran your Vi Your Tri State method is working good but First method i.e Null string given to Property is not working on my system. I am observing output through CRO.

If you can do something post here for my knowledge otherwise i am happy with given solution.

can you explain it little more...

And i also have some dought, cann't we use DAQmx Disconnect Terminals (VI) and DAQmx Connect Terminals (VI) for these type of operations?

thanks and regards,
