Intermittent memory hangup using Functional Global

[Ben]

One more thing...

You did not say if this 5 second delay was causing a problem. In most cases I will code expecting delays that large or larger if devloping in Windows.

hey guys,

I know this is kind of out of topic but i really really need help on this.

I am using EDC1000N camera from electrim and I cant save an image.  Can anybody help me on how to save an image using the provided software.


Thank you

Ben -

Thanks for your comments. The 5 second delay is abig deal to us, as each test sequence calls on the order of 500 VIs and takes approximately 2 seconds. When one of those VIs comsunes 5 seconds instead of 5 milliseconds, we notice. In previous versions of our application that did not use this kind of central LV2-style data management, we did not have this problem. Our application is used on the production line, where timing is critical.

I will try to put together a version of my LV2 global that you can hack around with. I'll need to slim it down quite a bit to simplify the problem, and then make sure that it's repeatable with that code.

On a side note: I did implement something like you described by changing the way the caller and the LV2 interact, with very good results. This will suffice as a workaround for now.

thanks again, Scott

Excellent!

Thank you very much for the update.

What version of LabVIEW are you using? I was having a mysterious freezing problem earlier this year and it turns out there is an issue with 8.21 and later that will cause LabVIEW to freeze for a period of time if there are certain Windows interrupts occuring. My problem happened when these hangups would hit when I was doing a long FFT and the FFT execution time would go from ~80 ms to up to 10 seconds. I switched to 8.2 and haven't had a single lock-up since. Might not be your issue, but we spent a month here on the forums trying to work it out.
