how to make a flashing led stay triggered when case structure is true

[iAnwar98]

Hi, I'm trying to create an alarm system in  which the alarms are triggered by the voltage coming from a DAQ unit going above the threshold of 3 volts. When the alarm is primed, it will blink at a rate of 2000ms. When the alarm is triggered, it will blink at a rate of 250ms. however, I would like the alarm to remain on once it has been triggered, even if the voltage from the sensor goes below 3 volts. I want the user to have to press the reset button to set the alarm back to 2000ms timing.  I have the alarm triggering but it will not stay triggered.

I have looked around on the forums on this site to see if I could find a way to do it, but i'm struggling to find a way that works for my particular project. 

Any help would be much appreciated.

Hi iAnwar,

I have the alarm triggering but it will not stay triggered.

Please do the LabVIEW basics offered in the header of the LabVIEW board to learn about shift registers!

And please learn about array handling too, to get rid of those 6 parallel loops doing essentially the very same for each of your 6 signals…

Maybe that will help ?

But yes, as GerdW mentionned, you should learn LabVIEW basics concerning flow, shift registers withing loops, arrays and stuff. Here is a nice start : http://www.ni.com/academic/students/learn-labview/ or http://www.ni.com/pdf/manuals/373427j.pdf
