CONSOLE OUT Switch
With a serial-port terminal program, you can use the Console Out switch to
read the IP address and BIOS version of the controller. Connect the serial
port on the controller to a computer. Push the switch to the ON position.
Make sure that the serial-port terminal program is configured to the
following settings:
•
9,600 bits per second
•
Eight data bits
•
No parity
•
One stop bit
The serial-port terminal program displays the IP address and BIOS version.
Keep this switch in the OFF position during normal operation.
DISABLE VI Switch
The position of the DISABLE VI switch determines whether any VIs run
at startup. You can instruct the cFP-21
xx
controller to run a VI when it
starts up, but if this VI consumes all of the cFP-21
xx
CPU resources for any
reason, it can make the module inaccessible on the network. If you reboot
the cFP-21
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-21
xx
controller starts up in safe mode. Safe mode disables all LabVIEW
functions and communication with I/O modules. If the software or
configuration information on the controller becomes corrupt or cannot be
read correctly, the system may hang after being rebooted or become
inaccessible over the network. Safe mode enables you to reconfigure
network settings and reinstall software on the controller.
Reboot the controller with the SAFE MODE switch in the ON position and
reinstall software using MAX. Then reboot the controller with the SAFE
MODE switch in the OFF position.
If reinstalling software does not work and you still cannot communicate
with the controller over the network, use the Format Disk function in MAX
to reformat the controller. Then reconfigure the TCP/IP settings, download
new software to the controller using MAX, and reboot the cFP-21
xx
with
the SAFE MODE switch in the OFF position.
