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
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.
