High Performance HMI Alarm Indicator Border Styles

Ignition Exchange
1

This exchange resource is a really nice way to implement showing alarms, as it abstracts the visual components away from physical components you have to place yourself, and instead defines them all within CSS. So adding an alarm border and the alarm icon itself is simply a matter of adding the style class to the component.

My one comment for improvement however, would be to add Perspective Styles for each of the CSS selectors so that they can be selected from the style.classes dropdown.

(You simply need to add skeleton Perspective Styles for each of the selectors which the stylesheet would merge with, however it would be prudent to then also rename the selectors so that they are grouped in the Perspective Styles)

e.g.

A few other suggestions:

  1. Replace these sections in the stylesheet:
  counter-reset: alarm-content var(--alarm-priority-number, 4);
  content: counter(alarm-content);

with:

  content: var(--alarm-priority-content-p4);

and add the variable into a root selector at the top:

:root {
  --alarm-priority-content-p4: "4";
}

The counter isn't needed.

  1. Set the text colour of the priority numbers according to the colour lightness of the icon colour. E.g. white text on red and magenta icon, black on the lighter colours yellow and orange.
  2. Replace values like this:
    var(--alarm-priority-color, magenta); with
    var(--alarm-priority-colour-p4); and then define these in the root at the top e.g.
:root {
  --alarm-priority-colour-p4: magenta;
}
