e-matica, as a Select Partner and System Integrator of OSIsoft, provides services to design, implement and deliver custom widgets for the OSIsoft 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

Update calculation results according to new values into the attribute list. Interact with the TreeView widget to select a specific AF Element. Attribute categories are used to define inputs and outputs.

Radar Chart

Display multivariate data in the form of a two-dimensional chart. Variables are represented on circumferential axes.

Data Table

Display AF element attribute values at set intervals within a time range. Move or hide columns. Download table contents in xlsx format. Add customized intervals.

Alarm Table

Quickly display AF element alarms based on configurable attributes. Navigate hierarchy by item selection or with the TreView widget.

Event Table

Display events from Event Frames (EF) in a given time range. Interaction with TreeView widget to select the AF element. Interaction with the Event Insert widget to start and stop EFs. Open custom displays, with trend and data tables, by clicking the associated icon. Show or hide EF attributes.

Event Insert

Insert Event Frames associated to the AF element selected by Tree View. Interaction with Event Table to show created Event Frames. Configurable Event Frames offset limits.

Manual Data Entry

Change AF Element attribute values. For PI point data reference also the tag data is updated at specified timestamp. Works with Web Service to support Back Fill Analysis.

QR Code reader

Automatically select displays and AF assets by a QR code, using the camera of a common smartphone or tablet.

 

Augmented Reality viewer

Visualize data with augmented reality technologies: real time data, 3D dynamic objects and external URL links.

Functionalities are available using any Windows tablet with a webcam and an internet browser.

Link I-Frame

Simply display web applications, remote documents or other PI Vision Displays in the same page. HTTP address choice based on AF Element attribute or with Tree View widget.

Gantt

Display AF Event Frames in a Gantt chart, according to the displayed time range. Works in stand-alone mode or with TreeView widget. Interaction with Event Table, Data Table and Alarm Table widgets.

On line calculation

Allows input values to be entered to determine the result calculated on the basis of complex formulas, defined in the PI-AF system, without modifying the real-time values of the system itself.

Column Chart

Visualize data through a histogram chart and other data lines.

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

Visualize data on a polar diagram enlightening critical issues and drifts also due to the possibility to compare different events (Event Frames).

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

Visualize Bode diagrams (freq/RPM) of the turbine in different transient time intervals, which derive from the appropriate beginning/end start-up conditions.

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.
