Good work but Attachment not found in the post.

It's hard to say for sure, but based on the performance I'd say some DAQ work shouldn't be a problem.  I'd guess you'd see significant performance issues if you tried taking something like N channels N samples at a very high rate, and then try to post process the data.  But this might be fine for say a log to TDMS and then display a subset of data.  

 

A quad core atom isn't nothing to sneeze at.  In the past I actually deployed a test system that ran on a dual core atom, running Windows XP.  It had a couple ethernet based cDAQ systems performing a sequence of events for controlling solenoids, and measuring mass flow.  Ultimately it was used to measure the efficiency of semi-truck air dryers.  We went with this PC because it was pretty small.  It had room for one PCI slot and was passively cooled, it was just a big heat sink that we could put in the cabinet with all the equipment.  We just attached a monitor on an arm and didn't need the whole second cabinet we were replacing.

Thanks for the detailed reply.  We too have successfully used Industrial PCs having Single Core Atoms (D425) and Duel Core Atoms (D525) for our LabView Applications in the past even on Windows 7. We have used both PCI and USB Cards for the purpose as the need arises. We only faced problem once when we tried to use two PCI Cards Simultaneously using a PCI Raiser Card which resulted in a resource conflict.

My main concern was that if the Tablet PC will be able to drive the USB DAQ Card and keep up with the required data transfer rates of data acquisition as in the Industrial Atom PCs. If that is possible then it seems to be a Great idea for us and many more people like us especially as there seem to more such products coming soon like one given below :-

Seriously? You posted this on a Sunday and waited 12 hours. Please be patient next time.

I confirmed the behavior in 2014 SP1 and 2015. In the hanging example I needed to zoom in, and then try to scroll horizontally. Zooming alone wasn't enough. I'd say this is probably some kind of corrupted VI or control. In 2015 I forced a recompile by pressing CTRL+Shift and clicking the run button and the VI that did hang no longer hangs.

Dear Friend,

Yes, I was little impatient to get the solution, so sorry for that.

I will try to recompile my main VI and see the result. Infact I had deleted the control all togather and made a new one and tested that in my main VI (with the same hanging result) before asking the question. And also the corrupt VI does not seems to be the answer as when we copy paste control to new VI we get same result.

I do perform some settings on graph control (set no. of plots, set color, line type of plots, set scale for different plots etc.) before displaying the data but they have worked for a long time in previous versions of labviews.

Any suggestions Please.

Thanks for the nice information.

Any Idea, if we can we attach a 16 Bit, 16 Channel USB DAQ Card to it for Data Acquisition?

Dear Friends,

Please see the attached VIs. Both VIs are containing same graph. While one VI hangs on zooming certain portion of the graph (towards the centre and end) the other VI is functioning well. The VIs have been named as per their behaviour.

Can someone please explain this behaviour.

With regards

Thanks guys for all suggestions. They are very useful for me. As soon as I get to the coding again I will implement your suggestions.

Dear Jakub,

Did you ultimate came out with some better solution?

I too was finding myself in similar type of situation :-)

Dear jdunham,

Can you please provide a small working example of your suggested MVC model?

Dear Friends,

Is there a way to download old attachments, for example http://forums.lavag.org/index.php?act=attach&type=post&id=6630
