Amanethiwekhi okuxhumana kwezimboni ayinsika yezimboni zanamuhla kanye nezimboni zezinqubo, edlala indima ebalulekile ekusebenzeni kwawo kanye nokusebenza kwawo. Kusukela ezitshalweni zokukhiqiza izimoto kuya ezindaweni zamakhemikhali eziyinkimbinkimbi kanye namalebhu e-robotics athuthukile, ukukhetha izintambo zenethiwekhi kungathinta kakhulu ukusebenza kahle kanye nokusebenza kahle kokuxhumana komshini. Inethiwekhi eklanywe kahle iqinisekisa ukuthi idatha idluliselwa ngokuthembekile nangokushesha, okuyinto ebalulekile ezindaweni ezidinga ukuqapha nokulawula ngesikhathi sangempela. Lesi sihloko sizogxila endleleni yokukhetha phakathi kwe-PROFIBUS ne-PROFINETizintambo.
1. Kuyini i-PROFIBUS?
I-PROFIBUS iyindinganiso ye-fieldbus evuthiwe eyethulwa ngasekupheleni kweminyaka yama-1980. Ngokuyinhloko ivumela ukuxhumana phakathi kwabalawuli be-automation namadivayisi asensimini afana nezinzwa, ama-valve, nama-drive. Iyaziwa ngokuqina kwayo nokuthembeka kwayo, evame ukusetshenziswa ekukhiqizeni nasekusebenzeni kwe-automation.
I-PROFIBUS isebenzisa ukuxhumana okulandelanayo okusekelwe kungqimba ebonakalayo ye-RS-485. Isekela amazinga edatha afinyelela ku-12 Mbps futhi ifanelekela i-topology yomugqa noma yebhasi. Ifaneleka kakhulu ezindaweni ezidinga ukuxhumana okuqondile.
2. Kuyini i-PROFINET?
I-PROFINET iyiphrothokholi yokuxhumana esekelwe ku-Ethernet eyakhiwe yi-PROFIBUS kanye ne-PROFINET International (PI). Yenzelwe ngqo ukushintshana kwedatha okusheshayo, ngesikhathi sangempela kumanethiwekhi ezimboni zanamuhla, isekela imisebenzi eyinkimbinkimbi yokwenza izinto ngokuzenzakalela.
I-PROFINET isekelwe kubuchwepheshe obujwayelekile be-Ethernet futhi isekela amazinga edatha kusukela ku-100 Mbps kuya ku-Gigabit speed. I-topologies yayo yenethiwekhi eguquguqukayo ifaka phakathi izinkanyezi, umugqa, indandatho, noma izakhiwo zesihlahla. Ifaneleka ukuzenzakalela okusebenza kahle kakhulu, amarobhothi, kanye nokulawula ukunyakaza.
3. Amakhebula e-PROFIBUS
Njengoba i-PROFIBUS ithembele ekusayineni kwe-differential serial, ukufakwa kwekhebula kumele kunciphise ukuphazamiseka kwe-electromagnetic (EMI) futhi kugcine ubuqotho besignali. Imininingwane ejwayelekile yekhebula le-PROFIBUS ifaka phakathii-pair ephikisiwe (i-STP) or i-UTP (i-UTP) engavikelwenge-impedance engu-100–120 ohms. Izintambo ezivikelwe ziyanconywa ezindaweni zezimboni ezine-EMI ephezulu. Ngamazinga aphansi e-baud, ubude bezintambo bungafinyelela kumamitha angu-1200. Izixhumi kufanele zibe yizinhlobo ze-M12, M8, noma ze-screw-terminal.
Sebenzisa izintambo eziqinisekiswe yi-PROFIBUS ukuqinisekisa ukuthi ziyahambisana, zivikele kahle phansi ukuze unciphise umsindo, futhi ugcine umzila wezintambo ufanelekile ukuze ugweme ukuphazamiseka.
4. Izintambo ze-PROFINET
I-PROFINET isebenzisa izintambo ze-Ethernet ezijwayelekile, isebenzisa izintambo zenethiwekhi yezentengiselwano. Ukukhetha izintambo ngendlela efanele kuqinisekisa ukuxhumana okusheshayo nokuthembekile, ikakhulukazi ezindaweni zezimboni ezinzima.
Imininingwane ejwayelekile yekhebula le-PROFINET yi-Cat5e, i-Cat6, noma ngaphezulu (kungcono ivikelwe ezingeni lezimboni). Ukuze uvikele, sebenzisa i-shielded twisted pair (STP noma i-S/FTP) ezindaweni ezinomsindo. Izixhumi ezinconywayo ziyi-RJ45 Ethernet ejwayelekile yezimboni. Ingxenye ngayinye yekhebula akufanele idlule amamitha ayi-100; amabanga amade adinga ukushintsha noma ukuphindaphinda.
Izindlela Ezinhle Kakhulu Ze-PROFINET:Sebenzisa izintambo ze-Ethernet zezinga lezimboni ezenzelwe izindawo ezinzima; qinisekisa ukuthi zibekwe phansi futhi zivikeleke kahle; sebenzisa izinkinobho zenethiwekhi yezimboni ukuze wandise noma uhlukanise inethiwekhi.
5. Yimuphi Umshini Okufanele Uwukhethe?
Sebenzisa izintambo ze-PROFIBUS:
-
Kwezinhlelo zendabuko noma izinhlelo zokuxhumana ezilandelanayo
-
Ezindaweni ezinokuphazamiseka okuncane kakhulu kwe-electromagnetic
-
Uma ukuxhumana okunezindleko eziphansi, okuthembekile kwanele
-
Ukuze ikhebula lisebenze kafushane ngaphakathi kwemishini noma amakhabethe okulawula

-
Ukuhlukaniswa:Yakha amanethiwekhi ukuze unciphise ubude bezingxenye futhi ugweme izihibe ezingadingekile.
-
Izinto Okucatshangelwayo Ngezemvelo:Khetha izintambo ezilinganiselwe izinga lokushisa, ukuchayeka kwamakhemikhali, kanye nokucindezeleka komshini endaweni ezungezile.
Zombili izintambo ze-PROFIBUS kanye ne-PROFINET zidlala indima ebalulekile kodwa zenzelwe izinhlelo zokusebenza ezithile. I-PROFIBUS imele i-process fieldbus futhi isibe ukukhetha okuthembekile, ikakhulukazi ezimbonini zenqubo zendabuko ezithembele ekwakhiweni kwayo okuqinile. Lezi zindawo zivame ukudinga ukuzinza kanye nokuvumelana futhi zizuza ekhonweni le-PROFIBUS lokugcina ukuxhumana okuthembekile emabangeni amade kanye nokucushwa kwenethiwekhi okuyinkimbinkimbi.
Uma ukhetha, cabanga ngengqalasizinda yakho, indawo ezungezile, kanye nemigomo yesikhathi esizayo. Khetha izixazululo ezihlala isikhathi eside, ezisebenza kahle kakhulu, futhi ezinokwethenjelwa ngisho nangaphansi kwezimo ezinzima kakhulu.
