9.3 PROFIBUS DP Overview PROFIBUS DP ishe/muranda, tokeni inopfuura network, inoshandisa chikumbiro/mhinduro protocol. Masevhisi ekuchinjana data anovimbisa kuti nguva nenguva, tenzi anotumira meseji inobuda kumuranda wega wega, uyo anopindurawo neinopinza meseji. PROFIBUS DP inowanzo shandiswa seI/O network. Sezvichienzaniswa neyechinyakare I/O network architecture inoda yakatsaurirwa wiring pakati pega yega I/O module uye controller mudziyo, PROFIBUS inopa mukana wetiweki imwe chete / bhazi panogara zvese zveI / O zvepamhepo. Fiber Optic Sezvo chimiro chemuviri kuExperion pari kushandisa chinongedzo chemagetsi, kushandiswa kwefiber optic media hakuzokurukurwa mugwaro iri. Zvinotarisirwa zvakadaro kuti zvigadzirwa zvakasiyana-siyana zvinotengeswa zvinogona kushandiswa neExperion system, iyo inobvumira kushandiswa kwemagetsi, pamwe nefiber optic media pane PROFIBUS DP network. Bhazi Wiring (yemagetsi) PROFIBUS DP inoshandisa "daisy-chain" bhazi topology, ine imwechete PROFIBUS tambo yakadzikwa kubva kuna tenzi kuenda kumuranda wekutanga uye kuburikidza nemuranda wega wega mune network. "Mapazi" anogona kutsigirwa kuburikidza nekushandiswa kwezvikamu, zvakaparadzaniswa nevanodzokorora, izvo zvinotsanangurwa muchidimbu pasi apa. Iyo yemagetsi wiring media inoshandiswa kuPROFIBUS ndeye nhovo yakamonyoroka peya (2 conductor pamwe nenhoo). Yakasarudzika tambo inosangana nePROFIBUS application inowanikwa mune zvekutengesa. Zvibatanidza zvinoshandiswa zvinowanzoita 9 pini Sub-D yekubatanidza, ine mapini 3 uye 8 anoshandiswa kune yakanaka/negative data masaini. Tarisa kune madhayagiramu emawaya emidziyo iri kushandiswa kuti uwane rumwe ruzivo. Zvishandiso zviri kumagumo echikamu chega chega zvinoda kumisa kunoshanda, dunhu iro rinowanzo kutsanangurwa pane perdevice. Neimwe nzira, PROFIBUS majoini ane yakasanganiswa yekumisa wedunhu anowanikwa mune zvekutengesa. Tarisa kune mudziyo wehunyanzvi zvinyorwa kuti uwane rumwe ruzivo nezve wiring uye kumisa. Device Profiles Nekuda kwekushaikwa kwetsanangudzo padhizaini yekuratidzira, iyo PROFIBUS Trade Organisation (PTO) yakatsanangura seti yemaprofile emudziyo anopa imwe nhanho yekumisikidza kune mimwe michina yakaoma. Aya maprofiles haasi chikamu cheiyo PROFIBUS protocol tsananguro, saka haaonekwe sechikamu chePROFIBUS yekutaurirana modhi inoratidzwa pamusoro. Nekudaro, kune mamwe maturusi aya maprofile emudziyo anopa imwe dhigirii yekumisikidza pane data management layer. Ziva kuti vatengesi vemidziyo havafanirwe kushandisa aya maprofile. Seti yemaprofayiri aripo anosanganisira anotevera:  Mbiri yekutaurirana pakati pevanodzora  Mbiri yezvigadziriso zvekudzora midziyo  Mbiri yeNC/RC controllers (marobhoti)  Profile yezvinosiyana zvinomhanyisa madhiraivha  Profile yeEncoders  Profile yeHMI masisitimu  Profile yekuchengeteka.
