	write channel properties specifies whether to write the channel properties when the VI runs. You can set this input to TRUE the first time the VI runs, and thereafter set it to FALSE to speed up the VI. The default is TRUE.
	tdms file is a refnum to the .tdms file to perform the operation on. Use the TDMS Open function to open the refnum.
	group name in specifies the channel group to perform the operation on.
	channel names in specifies the channels to perform the operation on.
	even-angle signals specifies an array of data resampled at even-angle intervals. even-angle signals are synchronous to the rotational speed with a constant number of samples per revolution. r0 specifies the start of the revolution index. dr specifies the revolution interval between two sequential samples. Y specifies the values of even-angle spaced samples in a scaled engineering unit.
	error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function 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 exception control to treat what is normally an error as no error or to treat a warning as an error. 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 VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function 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 VI or function that produced the error or warning. The default is an empty string.
	even-angle channel info contains information that you can pass from another VI about the measurement configuration for even-angle signals. Do not change the values in even-angle channel info. If you want to view the information, you can create a custom probe.
	even-angle position info specifies the position information of even-angle signals. positions [s] specifies the locations of the samples in seconds. samples/rev specifies the number of samples per revolution.
	tdms file out generates a tdms file reference to the .tdms file you performed the operation on.
	group name out returns the name of the channel group you performed the operation on.
	channel names out returns the names of the channels you performed the operation on.
	error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function 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 VI or function that produced the error or warning.

SV TDMS Write Order Track (1 Ch)

	write mode specifies how LabVIEW writes data to an existing file. For continuous data, select Append to append the streaming data to the existing group and channel(s). For block-based data, such as a spectrum, select New group to create a new group of data in the existing file. This VI does not support overwriting existing channels of data. To edit the data of an existing channel, you can read the data and then write modified data to a new file, group, or channel.
	tdms file is a refnum to the .tdms file to perform the operation on. Use the TDMS Open function to open the refnum.
	group name in specifies the channel group to perform the operation on.
	channel name in specifies the channel to perform the operation on.
	order component specifies the order component. X specifies the speed, time, or revolutions of the order components. Y specifies the data values of the order components.

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 VI or function that produced the error or warning. The default is an empty string.
	component specifies the spectrum component. The valid values are Magnitude, Phase, Real, Imaginary, Coherence, and Unknown.
	spectrum info contains information about the spectrum that you can pass from another VI. Do not change the values in spectrum info. If you want to view the information, you can right-click the spectrum info wire and select Custom Probe»Spectrum Info or Custom Probe»Power Spectrum Info from the shortcut menu.
