Troubleshooting and

Common Questions

This appendix describes how to troubleshoot problems with the NI-DNET
software and answers some common questions.

Troubleshooting with the Measurement & Automation

Explorer (MAX)

MAX contains configuration information for all CAN (DeviceNet)
hardware installed on your system. To start MAX, double-click on the
Measurement & Automation icon on your desktop. Your CAN cards are
listed in the left pane (Configuration) under Devices and Interfaces.
You can test your CAN cards by choosing Tools»NI-CAN»Test all Local
NI-CAN Cards from the menu, or you can right-click on an CAN card and
choose Self Test. If the Self Test fails, refer to the Troubleshooting Self Test
Failures section of this appendix.
Missing CAN Card
If you have a CAN card installed, but no CAN card appears in the
configuration section of MAX under Devices and Interfaces, you need to
search for hardware changes by pressing <F5> or choosing the Refresh
option from the View menu in MAX.
If the CAN card still doesn’t show up, you may have a resource conflict in
the Windows Device Manager. Refer to the documentation for your
Windows operating system for instructions on how to resolve the problem
using the Device Manager.
