H. Operation

DIP Switches


30/43

30

H. Operation

Safe Mode Switch

Determines whether the embedded LabVIEW Real-Time engine

launches when the controller boots. Normal operation is the OFF position.

If ON only the essential services required for updatingconfiguration and installing software are loaded.

Use ON if the software on the controller is corrupted.

Automatic boot safe mode if there is no software on the controller

ON required to reformat the drive

Refer to MAX Help for more about installing software andreformatting the drive.


31/43

31

H. Operation

Console Out Switch

Read the IP address and BIOS version of the controller with a

serial-port terminal program. Serial-port Configuration:

9,600 bits per second

Eight data bits

No parity

One stop bit

No flow control

Keep the Console Out switch in the OFF position during normaloperation.


32/43

32

H. Operation

IP Reset Switch

ON position and reboot resets the IP address to 0.0.0.0. If on your local subnet and the IP Reset switch is ON,

the controller appears in MAX with IP address 0.0.0.0.

Configure a new IP address for the controller in MAX. ON unlocks a controller that was locked in MAX.

Keep the IP Reset switch in the OFF position during

normal operation.


33/43

33

H. Operation

Restore Defaults

If the controller is not able to communicate with the network

Changes the IP address, subnet mask, DNS address, andgateway to 0.0.0.0

Does not affect power-on defaults, watchdog settings, or VIs

To restore defaults: Move the IP Reset DIP switch to the ON position.

Push the Reset button to cycle power to the controller. The StatusLED flashes once, indicating that the controller IP address is

unconfigured. Move the IP Reset switch to the OFF position.


34/43

34

H. Operation

No App Switch

ON prevents a LabVIEW startup application fromrunning when the controller powers on.

To permanently disable the application from running at

power up, disable it in LabVIEW. To run an application when the controller powers on,

push the No App switch to the OFF position, and

configure the application in LabVIEW to launch whenthe controller powers on.

H. Operation

User1 Switch

Users define the behavior of the User1 switch with the

RT Read Switch VI in a LabVIEW Real-Time embedded

application.

H. Operation

9012 Controller LEDs


37/43

37

H. Operation

Power LED Lit indicates the power supply is

adequate, and the controller is supplying power to the

CompactRIO system.

FPGA LED Programmable for application debugging

or status. Refer to LabVIEW Help for information about

programming.

User1 LED Programmatically definable to meet the

needs of your application in the RT VI.


38/43

38

H. OperationStatus LED

Off during normal operation.

Indicates errors by flashing certain patterns: Slow, continuous flashing. The controller is unconfigured. Use MAX

to configure.

2 flashes Software error. Reinstall software. Use MAX Help.

3 flashes Safe Mode DIP switch is in the ON position. 4 flashes The controller software has crashed twice without

rebooting or cycling power between crashes. Controller may be outof memory. Review your RT VI.

Continuous flashing Unrecoverable error. Contact NI.

Continuously lit The flash memory card is corrupt. Reformat thehard drive on the controller. Refer to MAX Help.
