Ma network olumikizirana ndi mafakitale ndi maziko a mafakitale amakono ndi mafakitale opangira zinthu, omwe amatenga gawo lofunikira kwambiri pakugwira ntchito kwawo komanso magwiridwe antchito awo. Kuyambira mafakitale opanga magalimoto mpaka malo ovuta opangira mankhwala ndi malo ophunzirira apamwamba a robotics, kusankha zingwe zamaukonde kungakhudze kwambiri magwiridwe antchito ndi magwiridwe antchito a kulumikizana kwa makina. Network yopangidwa bwino imatsimikizira kuti deta imatumizidwa mwachangu komanso modalirika, zomwe ndizofunikira m'malo omwe amafunika kuyang'aniridwa ndi kuwongolera nthawi yeniyeni. Nkhaniyi ifotokoza momwe mungasankhire pakati pa PROFIBUS ndi PROFINETzingwe.
1. Kodi PROFIBUS ndi chiyani?
PROFIBUS ndi muyezo wokhwima wa fieldbus womwe unayambitsidwa kumapeto kwa zaka za m'ma 1980. Umalola makamaka kulumikizana pakati pa owongolera odziyimira pawokha ndi zida zam'munda monga masensa, ma valve, ndi ma drive. Umadziwika chifukwa cha kulimba kwake komanso kudalirika kwake, komwe kumagwiritsidwa ntchito kwambiri popanga ndi kukonza makina odziyimira pawokha.
PROFIBUS imagwiritsa ntchito kulumikizana kwa serial kutengera gawo la RS-485. Imathandizira kuchuluka kwa deta mpaka 12 Mbps ndipo ndiyoyenera kugwiritsa ntchito ma line kapena mabasi. Ndi yoyenera kwambiri malo omwe amafunikira kulumikizana kotsimikizika.
2. Kodi PROFINET ndi chiyani?
PROFINET ndi njira yolumikizirana yochokera ku Ethernet yopangidwa ndi PROFIBUS ndi PROFINET International (PI). Yapangidwira makamaka kusinthana deta mwachangu komanso nthawi yeniyeni m'maukonde amakono amakampani, kuthandizira ntchito zovuta zodziyimira pawokha.
PROFINET imagwiritsa ntchito ukadaulo wa Ethernet wamba ndipo imathandizira kuchuluka kwa deta kuyambira 100 Mbps mpaka liwiro la Gigabit. Mapangidwe ake osinthika a netiweki amaphatikizapo nyenyezi, mzere, mphete, kapena kapangidwe ka mtengo. Ndi yoyenera kugwiritsa ntchito makina odziyimira pawokha, ma robotiki, ndi kuwongolera mayendedwe.
3. Zingwe za PROFIBUS
Popeza PROFIBUS imadalira chizindikiro chosiyana cha serial, kukhazikitsa chingwe kuyenera kuchepetsa kusokoneza kwa electromagnetic (EMI) ndikusunga umphumphu wa chizindikiro. Mafotokozedwe a chingwe cha PROFIBUS wamba ndi awa:awiri opindika otetezedwa (STP) or awiri opotoka osatetezedwa (UTP)ndi impedance ya 100–120 ohms. Zingwe zotetezedwa zimalimbikitsidwa m'malo opangira mafakitale okhala ndi EMI yapamwamba. Pa liwiro lotsika la baud, kutalika kwa zingwe kumatha kufika mamita 1200. Zolumikizira ziyenera kukhala zamtundu wa M12, M8, kapena screw-terminal.
Gwiritsani ntchito zingwe zovomerezeka ndi PROFIBUS kuti muwonetsetse kuti zikugwirizana, zotchingira bwino nthaka kuti muchepetse phokoso, komanso kusunga njira yoyenera yolumikizira zingwe kuti mupewe kusokoneza.
4. Zingwe za PROFINET
PROFINET imagwiritsa ntchito zingwe za Ethernet zokhazikika, pogwiritsa ntchito zingwe za netiweki yamalonda. Kusankha bwino zingwe kumatsimikizira kulumikizana mwachangu komanso kodalirika, makamaka m'malo ovuta kwambiri amakampani.
Mafotokozedwe a chingwe cha PROFINET ndi Cat5e, Cat6, kapena apamwamba (makamaka otetezedwa ndi mafakitale). Pakuteteza, gwiritsani ntchito zingwe zopindika zotetezedwa (STP kapena S/FTP) m'malo aphokoso. Zolumikizira zomwe zimalimbikitsidwa ndi RJ45 Ethernet yokhazikika ndi mafakitale. Gawo lililonse la chingwe siliyenera kupitirira mamita 100; mtunda wautali umafuna ma switch kapena ma repeater.
Njira Zabwino Kwambiri za PROFINET:Gwiritsani ntchito zingwe za Ethernet zapamwamba zamafakitale zomwe zimapangidwira malo ovuta; onetsetsani kuti malo ndi chitetezo zili bwino; gwiritsani ntchito ma switch a netiweki yamafakitale kuti muwonjezere kapena kugawa netiweki.
5. Ndi Chingwe Chiti Chomwe Muyenera Kusankha?
Gwiritsani ntchito zingwe za PROFIBUS:
-
Kwa machitidwe achikhalidwe kapena mapulogalamu olumikizirana otsatizana
-
M'malo omwe mulibe kusokoneza kwamagetsi kochepa
-
Ngati njira yolumikizirana yodalirika komanso yotsika mtengo imakhala yokwanira
-
Kuti zingwe zigwire ntchito mwachangu mkati mwa makina kapena makabati owongolera
Gwiritsani ntchito zingwe za PROFINET:
-
Kwa mapulogalamu othamanga kwambiri komanso othamanga kwambiri
-
M'malo okhala ndi EMI yambiri omwe amafunikira zingwe za Ethernet zotetezedwa
-
Kuti pakhale ma topology a netiweki osinthasintha komanso osinthika
-
Mukaphatikizana ndi zipangizo zamakono zochokera ku Ethernet ndikumanga machitidwe oteteza mtsogolo
6. Malangizo Okhazikitsa Kuti Mulankhule Modalirika
-
Chitetezo Choyenera:Gwiritsani ntchito zotetezedwazingwendikuonetsetsa kuti zishango zili pansi bwino.
-
Kutumiza kwa Chingwe:Sungani zingwe zolumikizirana kutali ndi zingwe zamagetsi ndi malo olepheretsa.
-
Zolumikizira ndi Ma Terminal:Gwiritsani ntchito zolumikizira zamagetsi ndipo onetsetsani kuti malo olumikizira magetsi ndi otetezeka.
-
Kugawa magawo:Pangani maukonde kuti muchepetse kutalika kwa magawo ndikupewa kuzungulira kosafunikira.
-
Zinthu Zofunika Kuganizira Pazachilengedwe:Sankhani zingwe zomwe zimayesedwa malinga ndi kutentha, kukhudzana ndi mankhwala, komanso kupsinjika kwa makina m'chilengedwe.
Zingwe zonse za PROFIBUS ndi PROFINET zimagwira ntchito zofunika kwambiri koma zimapangidwa kuti zigwirizane ndi ntchito zinazake. PROFIBUS imayimira njira yolumikizirana ndipo yakhala chisankho chodalirika, makamaka m'makampani achikhalidwe omwe amagwiritsa ntchito njira zomwe zimadalira kapangidwe kake kolimba. Malo amenewa nthawi zambiri amafuna kukhazikika komanso kusasinthasintha ndipo amapindula ndi luso la PROFIBUS losunga kulumikizana kodalirika patali komanso makonzedwe ovuta a netiweki.
Posankha, ganizirani za zomangamanga zanu, malo anu, ndi zolinga zanu zamtsogolo. Sankhani mayankho olimba, ogwira ntchito bwino, komanso odalirika ngakhale pakakhala zovuta kwambiri.
