DISABLE VI Switch
The position of the DISABLE VI switch determines whether any VIs run
at startup. You can instruct the cFP-20
xx
controller to run a VI when it
starts up, but if this VI consumes all of the cFP-20
xx
CPU resources for any
reason, it can make the module inaccessible on the network. If you reboot
the cFP-20
xx
with the DISABLE VI switch in the ON position, the module
does not run any VIs at startup.
SAFE MODE Switch
The position of the SAFE MODE switch determines whether the cFP-20
xx
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-20
xx
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-20
xx
with the
SAFE MODE switch in the OFF position.
RESET IP Switch
The position of the RESET IP switch determines whether the IP settings of
the cFP-20
xx
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-20
xx
.
Serial Ports
Refer to the
cFP-20xx Compact FieldPoint Controller Overview
section of
Chapter 1,
Overview of Compact FieldPoint
, to find the serial ports on the
controller. If you are not running an embedded application, you must target
the cFP-20
xx
in order to access the serial ports. Refer to the
LabVIEW Help
for more information about targeting the cFP-20
xx
.
