Image Acquisition on cRIO

[timjm]

Dear Community:

We are trying to conduct image acuqisition on the cRIO and are running into in the process of debugging our program on the CompactRiO. We keep finding that connectivity is lost at the same point. Our program involves multiple routines where the frame grabber snaps an image for further analysis.

When running our program, we find that the first snap routine executes normally. However, when the program gets to the second snap routine, we find that we get an error message when it tries to snap again.

I was wondering if you had any knowledge as to what the cause is and  why we obtain a connectivity error upon execution of the second Snap VI.

Thanks.

Hi Tim,

Could you be a bit more specific about what kind of hardware you are using?  Are you using a GigE or IP camera off the cRIO port or do you have a cRIO module acting as a framegrabber?  Which cRIO controller?  Backplane?  Second, what about a grab?  (and was there any reason behind doing a snap in the first place?  There is added overhead with a snap versus a grab that may or may not be ideal for your acquisition)

Also, this question may be better suited on one of our other discussion forums (try the Vision board for example): http://forums.ni.com/t5/Machine-Vision/bd-p/200
