This appendix gives troubleshooting instructions for the cFP-21xx and
FieldPoint software. For more troubleshooting information, refer to the
Measurement & Automation Explorer Help for FieldPoint and the
Measurement & Automation Explorer Remote Systems Help.
If a runaway startup application causes the cFP-21xx to become
unresponsive, you must power down the cFP-21xx, 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-21xx in safe mode, and the embedded LabVIEW
Real-Time engine is not launched. Refer to the
Chapter 3, Feature Descriptions, for more information about these DIP
switches.
The cFP-21xx indicates specific error conditions by flashing the red
STATUS LED a specific number of times. Table A-1 describes the
STATUS LED flashing sequences and the corresponding error condition.
