I am getting these kinds of errors when I enable on my driver station!


I would be very grateful if anyone can help me!!!

I also get these errrors:

FRC: The loop that contains RobotDrive is not running fast enough. This error can occur if the loop contains too much code, or if one or more other loops are starving the RobotDrive loop.

Don't worry about this one unless you get a lot of them. One is normal for changing robot modes: Disabled, Teleop, Autonomous

ERROR <Code> -44061
This means your Teleop loop might be running too slowly.
It means you aren't calling Arcade or Tank Drive quickly enough.

ERROR <Code> -44003
Is if the camera is not connected or if it's still booting when the cRIO tries to talk to it.

ERROR <Code> -44027
Means you used one of the DIO's twice.
Probably just left one of your Opens with the default DIO 1 and it conflicted with something else you Opened using that same DIO.

Re: Driver Station Errors
 

I believe these are common, we recieve these and received them last year and didn't have a problem.
Your Camera is timing out. If you are not using the camera, make sure the Enable Vision control is False (if using LV, don't about the other IDE's). If you are using the Camera, is the indicator ring on the front of the Camera green?

In your Begin.vi, check to make sure you are not opening 2 references with the same Digital Input

Re: Driver Station Errors
 

FRC: The DIO channel has already been allocated.

This means that you have assigned the same channel to multiple DIO's , this could be causing the loop to slow down and cause it to time out.

Re: Driver Station Errors
 

Here is my Digital Input part of the Begin.vi!



Uploaded with ImageShack.us

But I dont think I have assigned same channels to two or more than two DIO s!

Re: Driver Station Errors
 

Actually I am getting lots of those errors!

This is just the one fourth of the errors I am getting!!!

-
Check to make sure that you have initialized all of the DIOs that you are using. We found out recently that if you forget to initialize something in the Begin.vi it will try to use the default values for it. This could be trying to create a default one on your Slot 4 DIO 1 channel. Also while it is trying to figure out the default it will cause a delay that triggers the watchdog problems.

Re: Driver Station Errors
 

That usually means the communication between the laptop and robot is flakey. It's slowed way down.

I saw this on one team still using last year's Classmate setup (with updated 2011 Driver Station).
The Classmate turned out to be "stuttering." They had too much going on on their laptop and it couldn't keep up with the robot.
That can be double checked by trying a different laptop running the Driver Station application.

It can also occur due to a weak or subpar wireless connection.
Does it still give these errors when you connect your laptop directly to the DLink on the robot via Ethernet cable?

I can't see images from Imageshack, so I can't give advice there.

Re: Driver Station Errors
 

I am getting some other error after I deploy the code:

LabVIEW: Failed to load shared library FRC_UserProgram.out on RT target device.

Deployment completed with errors

Re: Driver Station Errors
 

i also get this multiple times. how do we fix it.

Re: Driver Station Errors
 

With regards to the camera call, you can either not open it in begin or plug your camera in so it runs. It's timing out because it expects the camera to talk on the ethernet port and it isn't.

With regards to the other problems (loop running slow) we nailed this one tonight after a lot of work. What clued us in to our errors was that it was still happening even when the robot is disabled. We checked the VI's that were running in disabled and found references to things that we had removed from begin. We also found a duplicated reference in begin. After fixing those our 'loop too slow' disappeared.

Re: Driver Station Errors
 

how do you find the errors and know what to delete.

Re: Driver Station Errors
 

On the driver station, click on the Diagnostics tab. The list will have error information that other posts are referring to.

This is the error I am getting and I couldnt manage to solve it!

Here is my Teleop.vi
