Need help with Elapsed Time VI

[Alan Anderson]

I'm not entirely sure where and when you're trying to do this. I think you can make it do what you want by removing the while loops, deleting the Elapsed Time, replacing the watchdog feed inside the loops with watchdog "feed and delay", and using the error inputs and outputs of the various vi's to control the order of events. If you have last year's default LabVIEW code to look at, its Autonomous Independent shows how to do it.

I solved it this afternoon. I was over think the problem. You are right Alan, I don't need the loop and the elapse time vi, but I have to leave the watchdog feed tinggy( or else it will say watchdog not fed on the driver station). I just put a delay vi, set it to 4 sec and the set motor speed. Everything is working now. Thanks for helping me, both of you.

His point is that if you replace the Watchdog Feed with the Watchdog Delay and Feed, you don't need the while loop or a separate Delay.

The Watchdog Delay and Feed will feed the Watchdog periodically as it delays.

No, I'm talking about the time delay VI, not the watchdog delay vi.

Right... and what he is saying it to use the delay and feed VI instead of a delay and a feed separately.
