SVX Shaft Centerline Plot VI

Owning Palette: Machine Vibration VIs

Installed With: Sound and Vibration Measurement Suite

Prepares shaft centerline plot data for displaying on a Shaft Centerline Plot. A shaft centerline plot displays the averaged positions of the shaft center.

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.
DC gaps specifies the DC gap of the proximity probes.
time/rev/RPM specifies the time, revolution, or speed at which you measured the DC gap value.
DC gap value specifies the DC gap value at the time/rev/RPM.
unit labels specifies the unit labels of the DC gaps.
x unit specifies the engineering unit for the time/rev/RPM.
DC gap unit out specifies the engineering unit for the DC gap.
gap position info specifies the position information of DC gaps.
positions [s] specifies the time, in seconds, at which you measured the DC gap value.
samples/rev specifies the number of samples per revolution.
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.
channel properties specifies the shaft rotation direction, angle value of the proximity probe, and pair information of each channel.
direction specifies the direction in which the shaft rotates.
0CCW—(Default) Counterclockwise.
1CW—Clockwise.
probe angle [deg] specifies the angle value of the proximity probe. The default is 0.
pair specifies the pair number of each channel. You must specify the same pair number for a pair of proximity probes.
shaft centerline returns the shaft centerline plot.
attribute returns additional information about the plots. LabVIEW uses this information to display the data properly and to perform extended measurements.
probe x returns the DC gap value of the probe x.
probe y returns the DC gap value of the probe y.
reference returns the DC gap reference.
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.
