Uthungelwano lonxibelelwano lwemizi-mveliso luyintsika yeefektri zale mihla kunye namashishini enkqubo, adlala indima ebalulekileyo ekusebenzeni nasekusebenzeni kwawo. Ukusuka kwizityalo zokuvelisa iimoto ukuya kwiindawo ezintsonkothileyo zeekhemikhali kunye neelebhu zerobhothi eziphambili, ukukhethwa kweentambo zenethiwekhi kunokuchaphazela kakhulu ukusebenza kunye nokusebenza konxibelelwano lomatshini. Inethiwekhi eyilwe kakuhle iqinisekisa ukuba idatha ihanjiswa ngokuthembekileyo kwaye ngokukhawuleza, okuyimfuneko kwiindawo ezifuna ukubeka iliso kunye nokulawula ixesha langempela. Eli nqaku liza kugxila kwindlela yokukhetha phakathi kwe-PROFIBUS kunye ne-PROFINETiintambo.
1. Yintoni iPROFIBUS?
I-PROFIBUS ngumgangatho ovuthiweyo webhasi oqaliswe ngasekupheleni kweminyaka yoo-1980. Ngokuyintloko yenza unxibelelwano phakathi kwabalawuli abazenzekelayo kunye nezixhobo zentsimi ezinjengezoluvo, iivalve, kunye needrive. Iyaziwa ngokomelela kwayo kunye nokuthembeka, okuqhelekileyo kusetyenziswa kwimveliso kunye nenkqubo yokuzenzekelayo.
I-PROFIBUS isebenzisa unxibelelwano olulandelelanayo olusekwe kwi-RS-485 umaleko womzimba. Ixhasa iireyithi zedatha ukuya kwi-12 Mbps kwaye ifanelekile kumgca okanye i-topology yebhasi. Ifaneleke ngokukodwa iindawo ezifuna unxibelelwano oluqinisekileyo.
2. Yintoni iPROFINET?
I-PROFINET yiprotocol yonxibelelwano esekelwe kwi-Ethernet eyenziwe yi-PROFIBUS kunye ne-PROFINET International (PI). Yenzelwe ngokukodwa utshintshiselwano lwedatha olukhawulezayo, lwexesha lokwenyani kuthungelwano lwemizi-mveliso yanamhlanje, exhasa imisebenzi enzima yokuzenzekela.
I-PROFINET isekelwe kubuchwepheshe obuqhelekileyo be-Ethernet kwaye ixhasa amaxabiso edatha ukusuka kwi-100 Mbps ukuya kwisantya seGigabit. I-topology yayo yenethiwekhi eguquguqukayo ibandakanya inkwenkwezi, umgca, umsesane, okanye izakhiwo zomthi. Ifanelekile kwi-automation ephezulu yokusebenza, iirobhothi, kunye nolawulo lwentshukumo.
3. Iintambo zePROFIBUS
Kuba i-PROFIBUS ixhomekeke kwisignali ye-serial eyahlukileyo, ukufakwa kwentambo kufuneka kunciphise ukuphazamiseka kwe-electromagnetic (EMI) kunye nokugcina intembeko yesiginali. Inkcazo yentambo ye-PROFIBUS eqhelekileyo ibandakanyaisibini esijijekileyo esikhuselekileyo (STP) or iperi ejijekileyo engakhuselekanga (UTP)kunye ne-impedance ye-100-120 ohms. Iintambo ezikhuselweyo ziyacetyiswa kwiindawo zoshishino ezine-EMI ephezulu. Ngamazinga asezantsi e-baud, ubude bekhebula bunokufikelela kwi-1200 yeemitha. Izihlanganisi kufuneka zibe yi-M12, M8, okanye iintlobo ze-screw-terminal.
Sebenzisa i-PROFIBUS-certified cables ukuqinisekisa ukuhambelana, izikhuselo eziphantsi ngokufanelekileyo ukunciphisa ingxolo, kunye nokugcina umzila ofanelekileyo wekhebula ukuphepha ukuphazamiseka.
4. Iintambo zePROFINET
I-PROFINET isebenzisa i-Ethernet cabling eqhelekileyo, isebenzise iintambo zenethiwekhi yorhwebo. Ukukhethwa kwekhebula ngokufanelekileyo kuqinisekisa unxibelelwano olukhawulezayo, oluthembekileyo, ngokukodwa kwiindawo ezinzima zoshishino.
Imilinganiselo yentambo ye-PROFINET yi-Cat5e, i-Cat6, okanye ngaphezulu (ikukhethwa ukuba i-industrial-grade shielded). Ukukhusela, sebenzisa i-shielded twisted pair (STP okanye i-S/FTP) kwiindawo ezinengxolo. Izixhumi ezicetyiswayo ziyi-industrial-standard RJ45 Ethernet. Icandelo ngalinye lekhebula akufanele lidlule i-100 yeemitha; imigama emide ifuna utshintsho okanye abaphindayo.
PROFINET Iindlela ezigqwesileyo:Sebenzisa iintambo ze-Ethernet ezikwi-industrial-grade eyenzelwe iindawo ezinzima; qinisekisa umgangatho ofanelekileyo kunye nokukhusela; sebenzisa iiswitshi zothungelwano lwamashishini ukwandisa okanye ukwahlula inethiwekhi.
