Hi,
In phoebus, when you click on the icon "open", you can open "Example Display", and there there is a ton of examples, including LED examples. You can probably find what you want here.

And to answer approximatively I think you can make some kind of widget rule with the intersection of your ALARM and a simulated PV:
PV.ALARM="MAJOR" and sim://ramp(0,1,1)  then background_color = green else darker_green

Sim://ramp(0,1,1) = ramp from 0 to 1 every 1 second 

Maybe there is a more direct way

Cheers

Objet : Including a blinking LED in my Phoebus CSS GUI

Hi,


I do have a LED in my Phoebus CSS GUI which shows the alarm status of a PV. I like to make this LED blinks when this PV at "MAJOR" alarm status and stops blinking when the severity is not at "MAJOR" alarms status.


I am wondering whether there is some procedure to accomplish this ?


Thanks
