Test machine 's card 8512 was change to PCI, the application still the same, but machine cycle time add 1 second. Could you please give us some advice why this happen? Thank you very much!
Since this issue is directly related to your 8512 cards, it'd probably be best to move this question from the LabVIEW forums to the Automotive and Embedded Networks forums .
You'll be able to find many more engineers who are knowledgeable on your product line there.
