Panel: Dynamic Image SVG

Overview

This dashboard panel allows signal values and status to be mapped to elements (Text, Basic Shapes, and Groups) within a SVG image. When signals are mapped to text, the Signal value will be displayed in that text field.

Images can be basic or very advanced for use cases such as:

  • Showing a dynamic version of asset / machine schematics
  • A dynamic view of a site layout
  • An HMI (Human Machine Interface) representation

Info

This panel is not enabled by default as using SVG images is an advanced use. Administrators with feature control access can enable this panel for use by users.

SVG Requirements / Formatting

Info

An SVG file is similar to HTML and CSS. The SVG specification was developed by the World Wide Web Consortium (W3C) and is an open standard. The ExoSense Dynamic Image panel uses this open standard and relies on the browser to display the file correctly.

SVG files can be loaded and displayed by a web browser by default. It's important to note that different browsers will handle the SVG slightly different. The more complex it is, including styles and fonts, the more likely it may look differently on two different browsers.

Those creating SVG images should test and verify on browses they expect to use.

Elements that will be used with signals in the panel must use an element id that begins with the prefix exo-. An example for a text element that will show a temperature signal value might be exo-temperature-value.

When loading the SVG, the panel will look for all elements that have this prefix and provide an option to use it in the panel.

Example of the Original SVG file

Here is a basic example of the SVG XML

Example SVG XML, note the`exo-` ids.

Configuration Options

  • Select signals
  • Upload the SVG
  • Turn on elements that you want to map to signals / signal status
  • For Each element
  • Pick a signal
  • Text Elements
    • Display the value or Interpret using a range
    • The color to use when interpreting
    • The text to show - default is the signal value but can be mapped to other text
  • Polygon / Shapes
    • Rule status or Interpret
    • Matches based on rule status or value matches
    • The color to use when interpreting

Here is the outcome and how signal values / status are used by elements in the SVG.

Info

If you make updates to your SVG source file and re-upload it, the panel will use any existing elements that have the same id as before.

Timeout Handling

When a signal has not reported in the expected timeout setting period, the Dynamic Image panel will show a grey value or a "--" when the 'Hide Value During Timeout' option is enabled.
