Waveform

This widget presents multiple waveforms taken over the dynamic points of the machine snapshots. It allows to visualize the waveforms captured online by the data acquisition hardware, as well as those stored in the database, providing a quick access to the capture history through its navigation tools.

Funcionality

Widget components and operation are described below.

Icon

Name

Description

Play/Pause

Play button allows to put the widget in online mode, automatically updating the last measurements taken by the acquisition hardware. Pause button stops the online mode, so the Widget will stop updating the values taken by the hardware.

Previous

Displays the measurement previous the widget visualization of those stored in the database.

Next

Displays the measurement after the widget visualization of those stored in the database.

Timeline

It displays the acquisition history timeline, which provides quick and easy access to the measurements recorded on a given date.

Information

Displays or hides the waveform information window. 

This window displays point, machine and waveform information.

  • Machine: name, status and alarm condition during capture, and its rotational speed.

  • Point: name, DC value provided by the sensor (bias).

  • Waveform: overall value, acquisition mode, number of points, acquisition time and date and time at which it was measured.

Cursors

Allows you to add up to 10 different cursors in the waveform. Each cursor will be assigned a different color by default.

Single Cursor

Selects the single cursor type.

Difference cursor

Selects the difference cursor type, which allows ti display equidistant time periods on both sides of a reference.

Double cursor

Selects the double cursor type, which allows to display equidistant time periods on both sides of a reference.

Cursors information

Displays or hides the cursor information window, which shows the data of the displayed cursors in the waveform (amplitude, frequency, units). For the difference and double cursors it also shows the distance to the main cursor in seconds, frequency and rotation commands.

Clear all

Removes cursors displayed on the waveform.

Spectrum

Displays the spectrum stored in the capture for the same point and spectrum acquisition mode.

Parameter Matrix

Displays the parameter matrix of the machine capture on which the waveform was measured, thus showing all the parameters of the dynamic points of the machine and the measurements of the static points.

Reset zoom

Resets the graph zoom.

Configuration

The widget, once created, must be configured to select the data source and display options. To do so, select the Configuration icon, located in the upper right corner.

The following window shows the configuration options:

The Widget allows multiple waveforms to be displayed on the same graph, in which case several data sources must be configured. For this purpose, the configuration window has a bar on which several data sources can be added and the one to be configured can be selected by means of the corresponding tabs.

 

To create a new data source, click on the following button:

 

This will create a new tab, automatically assigning a color to it and displaying the particular configuration options for this measurement.

To access the options for the other data sources just click on the corresponding tab.

The following table shows the general widget configuration options as well as the particular ones for each data source or measurement that the graph will show.

Field

Description

Nombre
(name)

Widget identifier. This text appears in the upper left part of the widget.

Máquina
(machine)

Selects the machine of the measurement displayed in the widget.

Visible

Defines if the corresponding waveform graph will be visible or hidden.

Color

Selects the color to be used in the waveform graph.

Punto dinámico
(Dynamic point)

Selects from a drop-down list the machine point and component to which the waveform measurement to be displayed belongs.

Modo de adquisición
(Acquisition mode)

Selects from a drop-down list the waveform acquisition mode to be displayed by the widget.

Anteriores y posteriores
(Previous and subsequent)

Selects desired waveform date, as well as the previous and next number of waveforms to be displayed.

Entre fechas
(between dates)

Selects the date range for displaying the waveform, as well as the maximum number of waveforms to be displayed.

Personalizado
(Customized)

Saves the selected dates in the timeline, allowing to delete them all.

Unidad de medida
(Unit of measurement)

Selects from a drop-down list the units of measurement in which the amplitude values of the waveform will be represented.

Actualizar espectro en
(Update spectrum in)

Selects from a drop-down field the linked widget in which the spectrum associated with the waveform will be presented. The drop-down presents the list of spectra widgets on the desktop.

Actualizar matriz de parámetros en
(Update parameter matrix in)

Selects from a drop-down field the linked widget in which the parameter matrix of the machine capture on which the waveform was taken will be updated. The drop-down presents the list of parameter matrix widgets on the desktop.

Grid line

Displays a grid over the graph.

Mostrar toolbar
(Show toolbar)

Displays the widget toolbar at all times. This toolbar is always displayed when maximized. When not maximized it will be displayed depending on what is selected in this option.
