cFP-20xx and cFP-BP-x User Manual
The position of the DISABLE VI switch determines whether any VIs run
at startup. You can instruct the cFP-20xx controller to run a VI when it
starts up, but if this VI consumes all of the cFP-20xx CPU resources for any
reason, it can make the module inaccessible on the network. If you reboot
the cFP-20xx with the DISABLE VI switch in the ON position, the module
does not run any VIs at startup.
The position of the SAFE MODE switch determines whether the cFP-20xx
controller starts up in safe mode. If the software or configuration
information on the module becomes corrupt or cannot be read correctly,
the system may hang after being rebooted or become inaccessible over the
network. All LabVIEW functions are disabled in safe mode, and I/O
module data is not accessible.
If you reboot the cFP-20xx with the SAFE MODE switch in the ON
position, the embedded LabVIEW RT engine does not start; the module
starts up in safe mode. Now you can reconfigure the TCP/IP settings,
download new software using MAX, and reboot the cFP-20xx with the
SAFE MODE switch in the OFF position.
The position of the RESET IP switch determines whether the IP settings of
the cFP-20xx controller are reset at startup. Reset the TCP/IP settings if you
are moving the module from one subnet to another or if you suspect that the
current TCP/IP settings are bad. Refer to the Measurement & Automation
Explorer Help for FieldPoint for more information about resetting the
cFP-20xx.
Refer to the cFP-20xx Compact FieldPoint Controller Overview
Chapter 1, Overview of Compact
controller. If you are not running an embedded application, you must target
the cFP-20xx in order to access the serial ports. Refer to the LabVIEW Help
for more information about targeting the cFP-20xx.
