ger ▁D DC ▁controllers ▁provide ▁network ▁communic ations ▁for ▁these ▁dedicated ▁controllers . ▁There ▁are ▁many ▁well ▁established ▁binary ▁protocol s ▁( B AC net , ▁L on T alk , ▁Mod bus , ▁D AL I ) ▁that ▁are ▁used ▁on ▁these ▁dedicated ▁networks ▁in ▁addition ▁to ▁numerous ▁propriet ary ▁protocol s . ▁While ▁these ▁binary ▁protocol s ▁can ▁be ▁used ▁over ▁TCP / IP ▁networks ▁- ▁they ▁have ▁challeng es ▁with ▁rou ters , ▁fire w alls , ▁security , ▁and ▁compatibility ▁with ▁other ▁network ▁applications . ▁There ▁is ▁an ▁added ▁challenge ▁in ▁that ▁the ▁industry ▁is ▁split ▁between ▁several ▁largely ▁in compatible ▁protocol s . ▁ ▁Because ▁o B IX ▁integr ates ▁with ▁the ▁enter prise , ▁it ▁enables ▁mechanical ▁and ▁elect rical ▁control ▁systems ▁to ▁provide ▁continuous ▁visibility ▁of ▁oper ational ▁status ▁and ▁performance . ▁By ▁expos ing ▁these ▁operations ▁using ▁web ▁services , ▁it ▁enables ▁own ers ▁and ▁ten ants ▁to ▁use ▁the ▁full ▁array ▁of ▁standard ▁databases ▁and ▁O L AP ▁tools ▁to ▁analy se ▁their ▁performance . ▁o B IX ▁enables ▁facilities ▁operators , ▁own ers ▁and ▁ten ants ▁to ▁make ▁dec isions ▁based ▁on ▁a ▁fully ▁integrated ▁consideration ▁of ▁all ▁life - cycle , ▁environmental , ▁cost , ▁and ▁performance ▁factors . ▁ ▁S cope ▁▁ ▁o B IX ▁provides ▁a ▁public ly ▁available ▁web ▁services ▁interface ▁specification ▁that ▁can ▁be ▁used ▁to ▁obtain ▁data ▁in ▁a ▁simple ▁and ▁secure ▁manner ▁from ▁H V AC , ▁access ▁control , ▁util ities , ▁and ▁other ▁building
