Labview programming help - Deploy mode not working

Technical Programming

Hi there,

          I have a programming doubt.I deployed the simple motor program VI and it worked perfect in run or Live debugging mode. If I  try to deploy it from the project explorer window it deploys the  program successfully but I'm not getting the motor to run.I tried changing the value of the constant in VI to 0.1 but still it doesn't turn the motor anyways.Can you help me out with this?

Thanks and regards,
Murthy

I’m assuming you really mean the “Motor Control Example”?

I hope you set a default speed on the Front Panel before you built & deployed it. Depending on the motor 0.1 could possibly be too slow to actually cause some motors to move.
It really isn’t setup to run deployed, since it requires the front panel to actually control anything and the front panel doesn’t get included as part of a deployment, and isn’t active when the cRIO gets rebooted.

Did you make “Motor Control Example.vi” your Startup vi when you created your build specification?
You’ll find that under the Build Specification that you created -> Properties -> Source Files.

I still like to use “Run as startup” too, rather than “Deploy”, just in case the “Always run deployed code at startup” wasn’t checked when the cRIO was last flashed.

Hello Mark!
Thanks for help.I actually didn’t build the application in the first place.I’m using the simple motor control VI from Labview site.I tried building the stand-alone .exe and now when I deploy the application ,it works fine for me.

But still am quite unsure as of why the deploy from project explorer window didn’t work?

Thanks,
Murthy

The deploy menu item in the project is deceiving. It is there really more as a test mechanism. What you really need to do is open the VI and push the run button on the top left of the toolbar.
