Hi to all

Is here some one who can tell me how i can make a buffered counting of the pulse count

This make sure i have a correct speed count/time

The problem also is that i also need to see on meter how fast the speed is i want to count as fast as possible ,but the meter must run at normal slow speed

Sorry guys i am new to labview to please do not be so hard on me ,

Any one who could help me?

Hi,

First of all, next time you should think about posting this into the hardware forums.

Buffered Counting is not possible with USB-6008!

Buffered operations for AI and AO, but not for counter operations.

Hi,

I agree, this is really strange!

Though I know that buffered operations are not possible with a USB-6008. It's a very simple counter just for edge counting and it can only be controlled per software, due to that you can only select "On Demand" Timing. And for bufferd operations you will need a hardware clock.

Let me check whats up with that manual or if I'm really wrong.

Hi,

As I said buffered counting is not supported with USB 6008. There is a mistake at the webpage.

However, could you explain a bit more in detail what you want to do, maybe we find another solution.

Hi Cristian

Well i count pulse´s to calc speed but i also need to display the speed at the same time,its already in a array but when i go slower as 1 sec in sampling data i get faults wrong speeds

if i want evry 0,1 the speed i get the error and since it has no sample i have no idea how to solve this

Christian,

Can you file a CAR for correcting the same?

@cees10: Please have a look at this thread: http://forums.ni.com/ni/board/message?board.id=250&message.id=49788&requireLogin=False

@muks: No, I didn't file a CAR, I reported it directly to the DAQ Marketing and they will correct it.

Hi Christian

what is the next device price wise that can handle then bufferd counting and pwm

Re: buffered counting 6008

It's the USB-6210. The pricing depends on the country you are, e.g. for Germany it would be EUR 579,-

I would suggest you to contact either your local NI Office or your NI Sales Representive about the pricing.

"Are there local office's in USA where i can buy NI products? "

Even when it's called "National Instruments" it's very international. NI was established in the US, in Texas in 1976 btw.
