Troubleshooting
This appendix gives troubleshooting instructions for the cFP-21
xx
and
FieldPoint software. For more troubleshooting information, refer to the
Measurement & Automation Explorer Help for FieldPoint
and the
Measurement & Automation Explorer Remote Systems Help
.
Runaway Startup Application
If a runaway startup application causes the cFP-21
xx
to become
unresponsive, you must power down the cFP-21
xx
, then reboot it with
either the DISABLE VI switch or the SAFE MODE switch in the ON
position. Rebooting the controller with the DISABLE VI switch ON
prevents any VIs from running at startup. Rebooting with the SAFE MODE
switch ON starts the cFP-21
xx
in safe mode, and the embedded LabVIEW
Real-Time engine is not launched. Refer to the
section of
Chapter 3,
, for more information about these DIP
switches.
