Consider the following scenario.
I have 100 tags with alert enabled for all of them. (These tags are UDT instances)
The values of these 100 tags are being displayed using an LED object. I have created a template for the same.
Now, I would like to make the background of the LED object change its color based on the alert condition. Also when the acknowledge button is pressed the background should hold the color and not flash. (This is very similar to the manual reset sequence in the ISA S-18.1).
I could do the background flashing part, using an expression tag and then linking it to the background color. The Expression tag calculated the alarm state.
However I would like to link the alarm acknowledge button for a particular tag to the background color of an object.
How do i go about this?
Looking forward to your reply.
