Widget Factory
e-matica, as a Select Partner and System Integrator of AVEVA, provides services to design, implement and deliver custom widgets for the PI Vision environment, according to custom needs and its own experience.
A set of implemented widgets are available and ready to use for specific needs. More will be developed.
Tree view
Navigation Menu
The Navigation Menu widget allows to create a button with a list of items chosen by the user in the widget configuration or retrieved directly from the AF.
The links to be opened by clicking on the items can be PIVision displays or external links.
HTML editor
The HTML Editor widget allows to view a text document in PIVision and allows complete customization in terms of styles, settings and colors.
Radar Chart
The EW Radar Chart widget allows, through different modes, to use a radar graph in order to:
- Visualize the historical trend of a quantity associated with a tag. The data used are sampled at regular time intervals.
- Compare the same attribute common to several elements;
- View multiple attributes of a single element;
- Compare several common attributes of different elements.
Data Table
Display AF element attribute values at set intervals within a time range. Add customized intervals. Download table contents in xlsx/csv format.
AF Data Table
The AF Data Table widget allows to view an AF table into PIVision. It is possible to insert filters and to color the rows/cells of the table according to their content.
TreeMap
The TreeMap widget shows graphically (by the size of the rectangle) and numerically a hierarchy of AF elements, displaying the value of a chosen attribute. The view hierarchy can be navigated with a click.
Alarm Table
Quickly display AF element alarms based on configurable attributes. Navigate hierarchy by item selection or with the TreView widget.
Event Table
Event Insert
Multiple Manual Data Entry
Link I-Frame
Gantt
On line calculation
Column Chart
This widget allows the visualization of data points on the chart at regular and configurable time ranges. Time axes coincide with the display range.
The components are:
- chart,
- legend,
- lines to help the chart comprehension (e.g. threshold, linear and medium regression).
Polar Diagram
This widget allows the visualization of data points on the chart at regular and configurable time ranges. Time axes coincide with the displayed range.
There are:
- chart,
- legend,
- lines to help the chart comprehension (e.g. threshold, linear and medium regression).
Time Slider
It allows time scrolling using a bar directly inlaid in the PI Vision display. Sliding the bar all the widgets on the display are synchronized to visualize data at the same point in time.
Bode Diagram Turbine
Sankey Diagram
Sankey widget allows to represent aggregate or totalized data in an AF table through a particular flowchart, where the arrows width is proportional to the amount of flow.
Sankey diagrams (or alluvial diagrams) are often used to signal energy, material, costs, losses or data transfers/movements in a process. Sankey diagrams often show preserved quantities.
The visualization through Sankey widget enables to easily identify big transfers or flows inside a system: they are useful for detecting dominant contributions in an overall flow.
FFT (Fast Fourier Transform) Diagram
Maintenance Data Entry
The Maintenance Data Entry widget allows to valorize an attribute linked to a PI Point and visualize its historical values. Through the historical view, in addition to the input values it’s possible to see the corresponding authors.
Sound Alarm
Reference Plot XY
The Reference Plot XY widget allows to visualize through a bi-dimensional diagram the link between two attributes belonging to the same element. In addition, by the definition of one or more AF tables, it’s possible to visualize a comparison between the data coming from the field and those in the tables.
3D Plot
The 3D Plot widget allows to visualize, through a three-dimensional scatter diagram, the relationship between three different attributes belonging to the same AF element.
Spin Value
The Spin Value widget allows to modify an attribute value (usually a parameter) by setting the raise / decrease step of the value and it returns to the default value by the reset button.
All colors and labels are modifiable in configuration.
MADT – Multiple Asset Data Table
The Multi Asset Data Table widget allows to compare attributes of different assets in a table.
Operative procedure
The Operative Procedure widget displays an interactive operating procedure, divided into steps, and keeps track of the sequence of choices made by the user, reporting if successfully terminated.
Stacked Chart
The Stacked Chart widget displays the data in a diagram like the one shown in the figure below.
Pie Chart
Pie Chart widget allows the visualization of data in a pie chart. The widget automatically calculates the percentage of each attribute shown in the chart.
Long Text
The LongText widget allows to view strings within the PIVision. The strings can be of any length and the user can decide the size of the text box, the text size, the text alignment and the colors of the text and of the background.
Compared to the standard “Value” widget, this widget allows to view very long texts and to wrap when you want by configuring the size of the text box.
Box Plot
The Box Plot widget allows you to view the statistics of the distribution of values of a measure within a time interval.
Advanced Trend Chart
The Advanced Trend Chart widget allows you to view a highly customizable trend in terms of scale (linear, logarithmic, quadratic), line style, marker, averages and stepped averages.
Switch widget
Switch widgetThe Switch widget allows to change the value of a Boolean attribute directly from PIVision. It is also possible to insert a confirmation question before proceeding with the modification.
Waterfall Chart
The waterfall chart widget shows a running total as values are added or subtracted. It’s useful for understanding how an initial value is affected by a series of positive and negative values.
HeatMap
The HeatMap widget shows a time graph where each rectangle has a certain color depending on the value of a third variable.
Show Tooltip
With the Show Tooltip widget the user is able to customize a tooltip with a totally user-configurable text (also in html format). The widget is a transparent area that shows the tooltip on hover.
DGA Matrix
The DGA Matrix widget allows you to view the DGA (Dissolved Gas Analysis) matrix within a PIVision display after dragging the 7 attributes relating to the 7 different Gases. The correlation between the dragged attribute and the gas is managed in the widget settings.
Map Viewer
User can also use their own layer.
Label widget
Playback
Image
Playback
The Playback widget allows you to move through the time of a PIVision display using a time step defined in the widget configuration.
