9.3 PROFIBUS DP Txheej txheem cej luam PROFIBUS DP yog tus tswv / qhev, token dhau lub network, uas siv cov txheej txheem thov / teb. Kev sib pauv cov ntaub ntawv yooj yim ua kom ntseeg tau tias nyob rau ib ntus, tus tswv xa cov lus tawm mus rau txhua tus qhev, uas teb rau hauv lem nrog cov lus tawm tswv yim. PROFIBUS DP feem ntau yog siv los ua I/O network. Raws li piv rau ib txwm I / O network architecture uas yuav tsum muaj kev sib txuas ntawm txhua qhov I / O module thiab cov khoom siv, PROFIBUS muab qhov zoo dua ntawm ib lub network / tsheb npav uas tag nrho I / O peripheral li nyob. Fiber Optic Txij li thaum lub cev cuam tshuam rau Experion tam sim no ntiav kev sib txuas hluav taws xob, kev siv fiber ntau optic media yuav tsis tham hauv daim ntawv no. Txawm li cas los xij, nws xav tias ntau yam khoom lag luam muaj peev xwm siv tau nrog Experion system, uas yuav tso cai rau kev siv hluav taws xob, nrog rau fiber ntau optic media ntawm PROFIBUS DP network. Kev xaim tsheb npav (hluav taws xob) PROFIBUS DP siv lub tsheb npav "daisy-chain" topology, nrog ib qho PROFIBUS cable txuas los ntawm tus tswv mus rau thawj tus qhev thiab los ntawm txhua tus qhev hauv lub network. "Branches" tuaj yeem txhawb nqa los ntawm kev siv ntu, cais los ntawm cov neeg rov hais dua, uas tau piav qhia luv luv hauv qab no. Cov khoom siv hluav taws xob siv hluav taws xob siv rau PROFIBUS yog ib qho thaiv kev sib tw (2 tus neeg xyuas pib ntxiv rau daim ntaub thaiv). Cov kab tshwj xeeb uas ua tau raws li daim ntawv thov PROFIBUS yog muag. Cov connectors siv feem ntau yog 9 tus pin Sub-D connector, nrog pins 3 thiab 8 siv rau cov ntaub ntawv zoo / tsis zoo. Xa mus rau cov kab kos duab rau cov khoom siv rau cov lus qhia ntxiv. Cov khoom siv ntawm qhov kawg ntawm txhua ntu yuav tsum muaj kev txiav tawm, uas feem ntau tau teev nyob rau hauv perdevice. Xwb, PROFIBUS connectors nrog ib qho kev sib txuas txiav tawm Circuit Court muaj muag. Xa mus rau cov ntaub ntawv qhia txog kev siv cuab yeej rau cov ntsiab lus ntxiv ntawm kev xaim thiab kev txiav tawm. Device Profiles Vim tias tsis muaj kev txhais ntawm cov txheej txheem nthuav qhia, PROFIBUS Trade Organization (PTO) tau txhais cov txheej txheem ntawm cov cuab yeej siv uas muab qee cov txheej txheem rau qee yam khoom siv nyuaj. Cov profiles no tsis yog ib feem ntawm PROFIBUS raws tu qauv txhais, yog li lawv tsis suav tias yog ib feem ntawm PROFIBUS kev sib txuas lus qauv piav qhia saum toj no. Txawm li cas los xij, rau qee yam khoom siv cov cuab yeej siv no muab qee qhov kev cai ntawm cov txheej txheem tswj cov ntaub ntawv. Nco ntsoov tias cov neeg muag khoom tsis tas yuav siv cov ntaub ntawv no. Cov txheej txheem muaj xws li cov hauv qab no:  Profile rau kev sib txuas lus ntawm cov tswj  Profile rau cov txheej txheem tswj cov cuab yeej  Profile rau NC / RC controllers (robotics)  Profile rau kev sib txawv ceev tsav  Profile rau Encoders  Profile rau HMI systems  Profile rau kev nyab xeeb
