Owning Palette: Tachometer Processing VIs

Installed With: Sound and Vibration Measurement Suite

Buffers the input signals and returns them in first-in first-out (FIFO) mode. The data type you wire to the XY signal input determines the polymorphic instance to use.

Use the pull-down menu to select an instance of this VI.

	reset? specifies the initialization of the internal states. The first time this VI runs, or when reset? is TRUE, the internal states initialize to zero. If reset? is FALSE, this VI sets the internal states to the final states from the previous call to the VI. The default is FALSE.
	XY signal specifies the XY signal to put into the buffer. X specifies the x-axis value of XY signal. Y specifies the y-axis value of XY signal.
	position info specifies the position information of XY signals. positions [s] specifies the locations of the samples, in seconds. samples/rev specifies the number of samples in one revolution.
	error in describes error conditions that occur before this node runs. The default is no error. If an error occurred before this node runs, the node passes the error in value to error out. This node runs normally only if no error occurred before this node runs. If an error occurs while this node runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node. status is TRUE (X) if an error occurred before this node ran or FALSE (checkmark) to indicate a warning or that no error occurred before this node ran. The default is FALSE. code is the error or warning code. The default is 0. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source specifies the origin of the error or warning and is, in most cases, the name of the node that produced the error or warning. The default is an empty string.
	buffer settings specifies the size and units of the buffer. buffer size specifies the size of the FIFO buffer. This buffer specifies the signal in FIFO mode. buffer unit specifies the buffer unit. 0 s—(Default) Specifies that the buffer unit is seconds. 1 revolution—Specifies that the buffer unit is revolutions. 2 # of samples—Specifies that the buffer unit is number of samples.
	buffered XY signal returns the XY signal this VI buffers. X returns the x-axis value of buffered XY signal. Y returns the y-axis value of buffered XY signal.
	error out contains error information. If error in indicates that an error occurred before this node ran, error out contains the same error information. Otherwise, it describes the error status that this node produces. Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error. status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source describes the origin of the error or warning and is, in most cases, the name of the node that produced the error or warning.
