Watchdog - no volt in DS

Technical Control System
1

Hello all,
We are trying to run our robot, with the new 2011 LabVIEW robot project framework and the new DS program. We have connection to the robot and the Axis cam image is displayed.

The problem is that the battery voltage is displayed as 00.00 although the AI breaker is powered (green light on) and the jumper is connected as it should be.
When we enable the robot the DS status text reads “Watchdog not fed”, which is weird as far as I know the WD was removed in the new 2011 project.
The DS error log shows error -63195 which is about the voltage input.

Thanks in advance, Shai, team 3083

Where is the cRIO module plugged in? In order for the voltage to be read, the NI 9201 analog input module must be in slot 1 of the cRIO.

If that’s where it is, check to make sure none of the DB15 pins are bent, and that there is no debris in the connector.

The module is well placed. We tried using an old LV version code and it works fine, but whatever we try to do in the new framework just fail to run, raising error 63195.
But know we also have camera problems (only with the new framework, in which it worked yesterday) the error code is 44003.

I am afraid we failed in running one of the updates or miss understanding something in the new 8.6.1 LV or in the 2011 Robot Project.

This is probably not a hardware problem.

I do not have the FRC tools installed on this computer, but if you go to the Help menu and select Explain Error…, you can type in those error codes and it will give you a better explanation as to what may be causing them.

In addition to the analog module installed in slot one, you must have the breakout card in place and the jumper on that device installed. The jumper puts battery voltage on the input to the analog module that is sampled and returned to the dashboard. This signal is also included in a packet that is read by the FMS during competition.
From Section 4
<R61> A National Instruments 9201 module must be installed in slot 1 of the cRIO-FRC . An analog breakout must be connected to this module. A jumper must be installed in the “Power” position (two outer pins) on the analog breakout. The analog breakout must be powered from the PD Panel. (Please refer to the 2011 FRC Control System Manual for details on these connections.)

What you describe suggests that the cRIO does not have the proper image installed. What cRIO image version does the Driver Station report?

Our cRIO image is V20 as much as I know.

I took a look in the code and saw that an error is provoked in the Get Refnam VI of our 4 motor drive. I don’t have the error number right now, but a search in Google showed that the error is probably caused by a difference between the computer version and the cRIO version.

I would appreciate a link to download a new cRIO image (if there is one) as well as help with updating our classmate (imaging card doesn’t work) and programing computer.

There’s your problem. The correct image at this time is v25.

Make sure you get all the Software Updates from the FIRST web site.

When you run the Utilities and LabVIEW updates, the latest image will be placed on your computer. Use the cRIO Imaging Tool to put it on the cRIO.

I don’t have enough information about your Classmate problem to give you any useful advice.

Thank you very much! Our robot works again. The problem was a failed LabVIEW update instlation, that failed to install V25 zip file.
