Owning Palette: Interrupt VIs

Requires: myRIO Toolkit, roboRIO Toolkit, or NI ELVIS RIO Control Toolkit

Registers analog input interrupts.


Hysteresis specifies in volts a window above or below Threshold. This VI uses hysteresis to prevent from false interrupt registration. The default is 0.02. Valid values are within the range [0, 1]. You do not need to change the value for this input unless you notice a false interrupt registration.
Allow Overwrite Operation? specifies whether to allow registering the specified interrupt more than once. The default is FASLE.
IRQ Number specifies the identifier of the interrupt to register. The default is 0. Valid values are within the range [0, 7]. You cannot register an I/O interrupt with the same IRQ Number as a registered I/O interrupt. However, after you unregister the existing interrupt, you can use the IRQ Number to register another interrupt.
Channel Name specifies the name of the analog input channel to open a reference. You must open a reference before this VI registers interrupts in an analog input channel.
Analog Interrupt Type specifies when to register the interrupt based on the analog input signal.

0Analog falling edge (default)—Specifies to register an interrupt on the falling edge of the analog input signal.
1Analog rising edge—Specifies to register an interrupt on the rising edge of the analog input signal.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
Threshold specifies the value in volts that the analog input signal must cross for this VI to register an interrupt.
Callback VI Reference specifies the reference to a callback VI. You must wire the vi reference output of the Callback VI Reference to this input.
error out contains error information. This output provides standard error out functionality.
