Troubleshooting
The NI Smart Camera Restarts Unexpectedly
Possible causes and solutions:
•
The smart camera is configured to acquire an IP address from a DHCP server, but no DHCP
server is available on the network. When the smart camera is configured to acquire an IP
address from a DHCP server, it waits for up to 60 seconds for the IP address to be acquired
successfully. If the smart camera does not receive an IP address within 60 seconds, it
restarts and attempts to acquire an IP address again. After three unsuccessful attempts to
acquire an IP address from a DHCP server, the smart camera restarts and enters an
unconfigured state. In the unconfigured state, the smart camera has an IP address of
0.0.0.0
and only limited software loads.
In the unconfigured state, the smart camera has network connectivity. If the smart camera
is on the same subnet as the host computer, then refreshing the list of remote devices in
MAX or Vision Builder AI will cause the smart camera to appear with an IP address of
0.0.0.0
. Use MAX or Vision Builder AI to reconfigure the smart camera IP address, then
restart the smart camera.
Refer to the
, for more information about assigning an IP address to the smart camera.
•
The smart camera has detected an error in the software configuration and automatically
restarted into safe mode, independent of the state of the SAFE MODE DIP switch. This
usually occurs when an attempt to upgrade the software is interrupted or if system files are
deleted from the smart camera by the user. Reinstall software on the smart camera. Refer
to Chapter 2,
, for information about installing software on the smart
camera.
•
The smart camera experienced two consecutive software exceptions. The smart camera
automatically restarts after an exception. After the second exception, the smart camera
remains in the exception state, alerting you to resolve the problem. To correct this issue,
reinstall software on the smart camera. Refer to the Chapter 2,
, for
information about installing software on the smart camera or contact National Instruments
for assistance.
•
In the event that the Direct Drive lighting controller detects an abnormal load condition,
such as a short circuit on the LED+ output, the smart camera stops image acquisition and
returns an error. The Direct Drive stops providing current to the light, and the smart camera
may restart. Ensure that your lighting wire connections are correct and/or reconfigure your
lighting settings in MAX or Vision Builder AI.
•
The voltage drop of the light may have exceeded the maximum voltage or minimum
voltage requirements of the smart camera. The voltage drop of a light can vary significantly
with environmental conditions, such as temperature, current, and strobe time. Verify that
the voltage drop across the LED+ and LED- terminals is within the specified range of the
smart camera. Your light may need to be reconfigured by the manufacturer to bring the
voltage drop within the specified range of the smart camera. Refer to Appendix A,
, for more information.
