LED num

Number of the LED that the VI modifies. The LED number depends on the type of hardware. LED num is zero-indexed. You can specify LED num 0 to control the User1 LED for most LabVIEW Real-Time targets.

datatype_icon

state

State to assign to the LED.

Name Description
Off

Turns off the LED

Default Color 1

Sets the LED to the device default color 1

Default Color 2

Sets the LED to the device default color 2 (if available)

Toggle

Toggles between off and device default color 1

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

LED state

Boolean value that indicates whether the LED is on or off.

True The LED is on.
False The LED is off.
datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: none

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
