Maukonde olumikizirana m'mafakitale ndiye msana wa mafakitale amakono ndi mafakitale amakono, omwe amagwira ntchito yofunika kwambiri pakugwira ntchito kwawo ndi magwiridwe antchito. Kuchokera ku mafakitale opanga magalimoto kupita ku malo opangira mankhwala ovuta komanso ma lab apamwamba a robotics, kusankha kwa zingwe zama netiweki kumatha kukhudza kwambiri magwiridwe antchito komanso mphamvu ya kulumikizana kwamakina. Maukonde opangidwa bwino amatsimikizira kuti deta imatumizidwa modalirika komanso mwachangu, zomwe ndizofunikira m'malo omwe amafunikira kuyang'anira ndi kuyang'anira nthawi yeniyeni. Nkhaniyi ifotokoza momwe mungasankhire pakati pa PROFIBUS ndi PROFINETzingwe.
1. Kodi PROFIBUS ndi chiyani?
PROFIBUS ndi mulingo wokhwima wamabasi womwe unayambitsidwa kumapeto kwa zaka za m'ma 1980. Imathandizira kulumikizana pakati pa zowongolera zokha ndi zida zakumunda monga masensa, ma valve, ndi ma drive. Ndiwodziwika chifukwa champhamvu komanso kudalirika, zomwe zimagwiritsidwa ntchito kwambiri popanga ndi kukonza makina.
PROFIBUS imagwiritsa ntchito kulumikizana kosalekeza kutengera gawo la RS-485. Imathandizira mitengo ya data mpaka 12 Mbps ndipo ndiyoyenera pamzere kapena ma topology a basi. Ndizoyenera makamaka kumadera omwe amafunikira kulumikizana kotsimikizika.
2. Kodi PROFINET ndi chiyani?
PROFINET ndi njira yolumikizirana yochokera pa Ethernet yopangidwa ndi PROFIBUS ndi PROFINET International (PI). Zimapangidwa makamaka kuti zikhale zothamanga kwambiri, zosinthana zenizeni zenizeni m'magulu amakono a mafakitale, kuthandizira ntchito zovuta zowonongeka.
PROFINET idakhazikitsidwa paukadaulo wa Efaneti wokhazikika ndipo imathandizira mitengo ya data kuchokera ku 100 Mbps mpaka kuthamanga kwa Gigabit. Maukonde ake osinthika amaphatikiza nyenyezi, mzere, mphete, kapena mitengo. Ndiwoyenera kuchita zinthu zodzichitira bwino kwambiri, ma robotiki, komanso kuwongolera koyenda.
3. Zingwe za PROFIBUS
Popeza PROFIBUS imadalira ma siginecha osiyanasiyana, kukhazikitsa chingwe kuyenera kuchepetsa kusokoneza kwa electromagnetic (EMI) ndikusunga kukhulupirika kwa ma sign. Zodziwika bwino za chingwe cha PROFIBUS zikuphatikizaawiri opotoka otetezedwa (STP) or opotoka awiri osatetezedwa (UTP)ndi impedance ya 100-120 ohms. Zingwe zotetezedwa zimalimbikitsidwa m'malo ogulitsa omwe ali ndi EMI yayikulu. Pamitengo yotsika ya baud, kutalika kwa chingwe kumatha kufika ku 1200 metres. Zolumikizira ziyenera kukhala M12, M8, kapena mitundu ya screw-terminal.
Gwiritsani ntchito zingwe zotsimikiziridwa ndi PROFIBUS kuti muwonetsetse kuti zimagwirizana, zishango zoyala pansi bwino kuti muchepetse phokoso, ndikuyendetsa njira yoyenera kuti musasokonezedwe.
4. Zingwe za PROFINET
PROFINET imagwiritsa ntchito chingwe cha Ethernet chokhazikika, kugwiritsa ntchito zingwe zamalonda zamalonda. Kusankhidwa koyenera kwa chingwe kumatsimikizira kulankhulana kofulumira, kodalirika, makamaka m'madera ovuta a mafakitale.
Zodziwika bwino za chingwe cha PROFINET ndi Cat5e, Cat6, kapena apamwamba (makamaka otetezedwa ndi mafakitale). Poteteza, gwiritsani ntchito zopotoka zotetezedwa (STP kapena S/FTP) pamalo aphokoso. Zolumikizira zovomerezeka ndi RJ45 Ethernet yamakampani. Chigawo chilichonse cha chingwe sichiyenera kupitirira mamita 100; mtunda wautali umafuna masiwichi kapena obwereza.
PROFINET Njira Zabwino Kwambiri:Gwiritsani ntchito zingwe za Efaneti zomwe zimapangidwira m'malo ovuta; kuonetsetsa kuti pansi ndi chitetezo chokwanira; gwiritsani ntchito ma switch a network network kuti muwonjezere kapena kugawa maukonde.
5. Kodi Muyenera Kusankha Chingwe Iti?
Gwiritsani ntchito zingwe za PROFIBUS:
-
Kwa machitidwe azikhalidwe kapena ma serial communication applications
-
M'malo okhala ndi kusokoneza kochepa kwa ma elekitiroma
-
Zikakhala zotsika mtengo, kulumikizana kodalirika kokhazikika ndikokwanira
-
Kwa chingwe chachifupi chimayenda mkati mwa makina kapena makabati owongolera
Gwiritsani ntchito zingwe za PROFINET:
-
Kwa ntchito zothamanga kwambiri, zothamanga kwambiri
-
M'malo a EMI apamwamba omwe amafunikira zingwe zotetezedwa za Ethernet
-
Kwa ma topology osinthika, osinthika
-
Mukaphatikizana ndi zida zamakono za Ethernet ndikumanga machitidwe amtsogolo
6. Kukhazikitsa Malangizo kwa Kuyankhulana Odalirika
-
Chitetezo Choyenera:Gwiritsani ntchito zotetezedwazingwendipo onetsetsani kuti zishango zakhazikika bwino.
-
Njira Yachingwe:Sungani zingwe zoyankhulirana kutali ndi zingwe zamagetsi ndi zosokoneza.
-
Zolumikizira ndi Ma terminal:Gwiritsani ntchito zolumikizira zamakampani ndikuwonetsetsa kuti ma terminal ndi otetezeka.
-
Gawo:Pangani maukonde kuti muchepetse kutalika kwa magawo ndikupewa malupu osafunikira.
-
Zolinga Zachilengedwe:Sankhani zingwe zovotera kutentha, kukhudzana ndi mankhwala, komanso kupsinjika kwamakina m'chilengedwe.
Zingwe zonse za PROFIBUS ndi PROFINET zimagwira ntchito zofunika kwambiri koma zimapangidwira ntchito zinazake. PROFIBUS imayimira njira ya fieldbus ndipo yakhala chisankho chodalirika, makamaka m'mafakitale achikhalidwe omwe amadalira mamangidwe ake olimba. Madera amenewa nthawi zambiri amafuna kukhazikika komanso kusasinthika ndikupindula ndi kuthekera kwa PROFIBUS kuti asunge kulumikizana kodalirika pamitali yayitali komanso masanjidwe ovuta a maukonde.
Posankha, ganizirani za zomangamanga, malo, ndi zolinga zamtsogolo. Sankhani njira zomwe zili zokhazikika, zogwira ntchito kwambiri, komanso zodalirika ngakhale pazovuta kwambiri.
