Need some help and ideas

ondrovic

I was told that I need to develop something that will do the following:

1.> If a clients system is inactive for 24 hours. It will need to turn off all the audio zones, and turn off all the source equipment.

2.> If any push from any device is recieved it will reset the timer.

3.> The code needs to be independent ( module maybe ) so we can add it to other programs we have done in the past.


I am thinking that the easiest way would be to create a timeline event but I haven't ever done this before, so I am looking for suggestions.

Thanks

A re-triggering timeline would work great.

If you have your system off in a sub routine it would be minimal amount of code, a module would be overkill.

This should get you headed in the right direction.

DEFINE_DEVICE

dvTP1	= 10001:1:0
dvTP2	= 10002:1:0

DEFINE_CONSTANT

nResetTL	= 1 //reset timeline id

DEFINE_VARIABLE

DEV	dvTPs[]	= {dvTP1,dvTP2} //array of all the TPs

LONG	lResetT[] = {86400000}	//24 hours in milliseconds

DEFINE_FUNCTION fnSystemOff () {
   //do whatever
}

DEFINE_FUNCTION fnResetTimer () {

   //kill the timeline if it is active
   IF(TIMELINE_ACTIVE(nResetTL)) TIMELINE_KILL(nResetTL)
   //and then create a fresh one
   TIMELINE_CREATE (nResetTL,lResetT,1,TIMELINE_ABSOLUTE,TIMELINE_ONCE)
}

DEFINE_EVENT

//trap all button events for all TPs
BUTTON_EVENT[dvTPs,0] {

   PUSH: {
      //if any button is pushed reset the timer
      fnResetTimer()
   }
}

TIMELINE_EVENT[nResetTL] {

   //time is up - let's turn everything off
   fnSystemOff()

}

Thanks guys I will give it a try and see where this takes me.

Joe,

Thanks it does exactly what I was looking for. I have one more question. Is there a way to get a realtime update of the amount of time that is left in the timeline? If there is whats the best way to do that?

Thanks again

LONG TIMELINE_GET (LONG Id)

ie,
TimeLeft = TIMELINE_GET(nResetTL)

returns the number of milliseconds elapsed since the start of the timer. Make sure you know about Help/NetLinx Keywords in Studio -- it's very helpful as a quick reference. Just searching the index for "timeline" yields a lot of useful info.
