▁autom ation ▁systems , ▁and ▁to ▁provide ▁data ▁exchange ▁between ▁facility ▁systems ▁and ▁enter prise ▁applications . ▁Release ▁ 1 ▁provides ▁a ▁normal ized ▁representation ▁for ▁three ▁of ▁elements ▁common ▁to ▁control ▁systems : ▁▁ ▁Point s : ▁representing ▁a ▁single ▁scalar ▁value ▁and ▁its ▁status ▁– ▁typically ▁these ▁map ▁to ▁sens ors , ▁actu ators , ▁or ▁configuration ▁variables ▁like ▁a ▁set point . ▁ ▁Al arm ing : ▁model ing , ▁routing , ▁and ▁acknowled gment ▁of ▁al ar ms . ▁ ▁Al ar ms ▁indicate ▁a ▁condition ▁which ▁requires ▁notification ▁of ▁either ▁a ▁user ▁or ▁another ▁application . ▁ ▁Histor ies : ▁model ing ▁and ▁query ing ▁of ▁time ▁sample d ▁point ▁data . ▁ ▁Typ ically ▁edge ▁devices ▁collect ▁a ▁time ▁stamp ed ▁history ▁of ▁point ▁values ▁which ▁can ▁be ▁fed ▁into ▁higher ▁level ▁applications ▁for ▁analysis . ▁ ▁o B IX ▁ 1 . 0 ▁provides ▁a ▁low ▁level ▁object ▁model ▁which ▁can ▁be ▁extended ▁during ▁implementation . ▁While ▁points ▁are ▁directly ▁address able ▁( and ▁thereby ▁set table ), ▁direct ▁interaction ▁with ▁the ▁points ▁requires ▁too ▁much ▁knowledge ▁of ▁the ▁underlying ▁control ▁system ▁for ▁the ▁enter prise ▁developer . ▁The ▁underlying ▁points ▁can ▁be ▁aggreg ated , ▁the ▁results ▁named , ▁alarm ▁levels ▁set , ▁and ▁histor ies ▁begun ▁using ▁the ▁o B IX ▁contract . ▁If ▁o B IX ▁ex poses ▁a ▁low ▁level ▁object ▁model ▁for ▁control ▁systems , ▁o B IX ▁contract s ▁create ▁the ▁higher ▁level ▁type ▁libraries ▁that ▁most ▁program mers ▁actually
