9.3 PROFIBUS DP Mwachidule PROFIBUS DP ndi mbuye/kapolo, wodutsa ma netiweki, omwe amagwiritsa ntchito njira yopempha/mayankhidwe. Ntchito zosinthira deta zoyambira zimatsimikizira kuti nthawi ndi nthawi, mbuyeyo amatumiza uthenga wotuluka kwa kapolo aliyense, womwe umayankhanso ndi uthenga wolowera. PROFIBUS DP imagwiritsidwa ntchito ngati netiweki ya I/O. Poyerekeza ndi mapangidwe amtundu wa I / O omwe amafunikira mawaya odzipereka pakati pa gawo lililonse la I / O ndi chipangizo chowongolera, PROFIBUS imapereka mwayi wa netiweki / basi imodzi yomwe zida zonse za I / O zotumphukira zimakhala. Fiber Optic Popeza mawonekedwe akuthupi ku Experion pakali pano amagwiritsa ntchito kulumikizana kwamagetsi, kugwiritsa ntchito fiber optic media sikudzakambidwa m'chikalatachi. Komabe, zikuyembekezeredwa kuti zinthu zosiyanasiyana zogulitsidwa zitha kugwiritsidwa ntchito ndi Experion system, yomwe ilola kugwiritsa ntchito magetsi, komanso fiber optic media pa netiweki ya PROFIBUS DP. Mawaya a Mabasi (zamagetsi) PROFIBUS DP amagwiritsa ntchito bus topology ya "daisy-chain", yokhala ndi chingwe chimodzi cha PROFIBUS cholumikizidwa kuchokera kwa mbuye kupita kwa kapolo woyamba komanso kudzera mwa kapolo aliyense pamaneti. "Nthambi" zitha kuthandizidwa pogwiritsa ntchito magawo, olekanitsidwa ndi obwerezabwereza, omwe akufotokozedwa mwachidule pansipa. Mawaya amagetsi omwe amagwiritsidwa ntchito pa PROFIBUS ndi awiri opotoka otetezedwa (2 ma conductor kuphatikiza ndi chishango). Chingwe chapadera chomwe chimakumana ndi pulogalamu ya PROFIBUS chilipo malonda. Zolumikizira zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala cholumikizira cha 9 pin Sub-D, chokhala ndi zikhomo 3 ndi 8 zomwe zimagwiritsidwa ntchito popanga ma data abwino/oipa. Onaninso zojambula zamawaya za zida zomwe zikugwiritsidwa ntchito kuti mumve zambiri. Zipangizo zomwe zili kumapeto kwa gawo lililonse zimafuna kuti zithetsedwe, zozungulira zomwe nthawi zambiri zimatchulidwa pa perdevice. Kapenanso, zolumikizira za PROFIBUS zokhala ndi gawo lophatikizika loyimitsa zimapezeka pamalonda. Onani zolemba zaukadaulo za chipangizochi kuti mumve zambiri za waya ndi kuyimitsa. Mbiri Zazida Chifukwa chosowa tanthauzo pagawo lowonetsera, bungwe la PROFIBUS Trade Organisation (PTO) lidatanthauzira mbiri yazida zomwe zimapereka mulingo wokhazikika pazida zina zovuta. Ma mbiri awa sali gawo la tanthauzo la protocol ya PROFIBUS, kotero samatengedwa ngati gawo la njira yolankhulirana ya PROFIBUS yomwe yawonetsedwa pamwambapa. Komabe, pazida zina ma profayilo a chipangizochi amapereka kukhazikika kwapanthawi yoyang'anira deta. Dziwani kuti ogulitsa zida sakufunika kugwiritsa ntchito mbiriyi. Mndandanda wa mbiri zomwe zilipo zikuphatikiza izi:  Mbiri ya kulumikizana pakati pa olamulira  Mbiri ya zida zowongolera njira  Mbiri ya olamulira a NC/RC (maroboti)  Mbiri yamagalimoto othamanga  Mbiri ya Encoder  Mbiri ya machitidwe a HMI  Mbiri yachitetezo
