Silence HORN

Hi All,

I'm trying to get the incoming alarm parameter to check if the priority is Advisory.

I tried "THISUSER/ALARMS[1].F_PRI"... but won't work due to hierarchy.

is there any other way of doing this?. customer wants to silence the horn after 2 seconds if alarm priority is advisory.

Thanks,

Gelo

  i'm thinking of using alarm count[5,6,7] on data change then silence the horn after a time delay.
  
  is there a way to find out if 1 specific sound wave is playing? so then if an Advisory tone is playing i would then silence it after a time delay
  
  Thanks

  Just a note:
  Value is negative if this is the first read of the HORN.CV with a new value. Value is < -100 if the sound can’t be played because another application is using the sound driver.
  
  So you could also have -5/-6/-7 and -105/-106/-107 but the < -100 shouldn't be sounding the horn so you shouldn't have to worry about these with your requested need.
