I changed the output also to ao and same situation

if i leave the counter as PFI8 and put the ouptut to AO it counts the single pulses but gives the same error for 2

I think you missed the main point of my first answer back in msg #2.  Your device uses up *both* counters when you configure one to generate a finite pulse train.  So you can't do both that *and* have another edge counting task.

The suggestions about using a dummy finite AI or AO task are to demonstrate that a *different* way to generate a finite set of pulses.  You would need to use one of those *instead* of a finite pulse train counter task, not in addition to.

The only other thing you'll need to add is the DAQmx Export Signal function (or property node) to export the AI or AO sample clock out to a particular PFI pin.

sorry my current labview level is not where it needs to be to understand your comments, to me it sounds like - "in order to fly a plane, you get in it and fly it"

i would need to see an example block diagram 

it that is beyond the scope of this post, i can just mark it as complete or delete it (not sure the general advice of -just use ai ao will help others)

You need to stop trying to generate a finite pulse train with a counter task because that will use up both counters on your device and you won't have one available for doing edge counting.  Go back to my answer in msg #7 and run *only* the 2 examples I mentioned.  Don't also try to run a finite pulse train with a counter. 

That pair of examples illustrates that an AI task can be used to generate a specific finite # of sample clock pulses.  Insert the following call to DAQmx Export Signal before you start the AI task to put the sample clock pulses out on PFI0.  That makes it available to physically wire to any external device that needs to receive your finite pulses.

you dont reference any examples by name, only "shipping examples" but my labveiw version doesnt show any

Since this thread is peppered with examples that you previously found without noted difficulty, I'm tentatively interpreting the last message as sarcastic and trolling and am thus bowing out.

Mea culpa, I was overly hasty to suspect being trolled, the OP remains sincere in trying to get things working.  This was cleared up in a PM (and thanks for reaching out).   One key bit of new info:

I found another NI device with a counter and think I can wire the 2 devices together and output pulses from the one device and count from another and hopefully wont get the error.

Yes, that should work.  I'd recommend you also run a wire to connect the Digital Grounds on the two devices.  There will be a lot of DGND terminals to choose from and it shouldn't really matter which one you use.  I typically just choose one near my signal wire.
