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.
|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.|
