IMAQdx problem with FireWire camera

[Gum51]

Hi,

I have some problem with IMAQdx. To my app, I use a FireWire 1394 camera with LabVIEW 2012, NI MAX 5.5 and Win7.

I capture images to be analysed it. My problem is the following : the application runs without problems (Open imaqdx session, GetImage, Close session…) but completly random, the vision does not longer work and displays the error message « No acquisition in progress » while communication is always open. And without change anything in my vision configuration… After this error, I leave the app to display an image in NI MAX. But I can’t show my image because the acquisition speed is itself amended (400Mbp to 100 Mbp). I try to fix it with a property node, but is it no more editable. When I unplug the device and plug it back, it still ok. I have some images…

Have someone a solution to my problem ? I found on the net that is a 1394 driver problem with Windows, but I don’t have found THE solution…

I posted on the french forum without solution.

Thank you in advance.

Hi Gum51,

can you attach your VI to see how it is programmed?

You told "I found on the net that is a 1394 driver problem with Windows, but I don’t have found THE solution."

Which link is this information located?

You use a FireWire 1394 camera (which one?) with LabVIEW 2012, NI MAX 5.5 and Win7 (in 64- or 32-bits?).

Which IMAQdx version do you use?

Best regards

Hi Suse,

Thanks to your answer, but I can't post my VI... To explain, I have a Init Part at the begining of my program (cfg files, paths, com, etc...). And take an image with a syncronous loop. At the end, I close all the communications. In my operating part, I take an image with "IMAQdx GetImage.vi" and display it to the FP.

I use a ImageSourcing DMK31AF03, win 32. I don't found the IMAQdx version...

All that I have found on the net for this problem, is to update my camera driver. And all my drivers are updated...

Thanks a lot!

Best regards

Thank you Suse for your links!

I use some personal libraries (with ground IMAQdx functions) but they are compatible.

All my labview versions are compatible...

I have some pictures but sometimes (4-5 times during a day), I have this problem. With a incompatibility that should never operate... (?)

Best regards

What versions do you use? Can you create a MAX-report?

1. Start -> Programs -> National Instruments -> open Measurement & Automation
2. File -> create protocol -> choose technical support and my system -> next -> next -> choose path -> next -> finish.

Do you use the functions from ImageSourcing?:

http://www.theimagingsource.com/de_DE/products/cameras/firewire-ccd-mono/dmk31af03/

It's with IMAQdx too.

Best regards

No, I only use my own libraries.

You see in attachment my MAX-report.

Thanks

Maybe it's a Firewall issue:

Do you get an error message? Can you make a screenshot of it?
