Amanethiwekhi okuxhumana ezimboni awumgogodla wezimboni zesimanje kanye nezimboni zezinqubo, ezidlala indima ebalulekile ekusebenzeni nasekusebenzeni kwazo. Ukusuka ezitshalweni zokukhiqiza izimoto kuya ezikhungweni zamakhemikhali eziyinkimbinkimbi kanye namalebhu athuthukile wamarobhothi, ukukhethwa kwezintambo zenethiwekhi kungathinta kakhulu ukusebenza kahle nokusebenza kokuxhumana komshini. Inethiwekhi eklanywe kahle iqinisekisa ukuthi idatha idluliselwa ngokwethembeka nangokushesha, okubalulekile ezindaweni ezidinga ukuqapha nokulawula kwesikhathi sangempela. Lesi sihloko sizogxila endleleni yokukhetha phakathi kwe-PROFIBUS ne-PROFINETizintambo.
1. Iyini i-PROFIBUS?
I-PROFIBUS iyindinganiso ye-fieldbus evuthiwe eyethulwa ngasekupheleni kwawo-1980. Inika amandla ngokuyinhloko ukuxhumana phakathi kwezilawuli ezizenzakalelayo namadivayisi enkundla njengezinzwa, ama-valve, namadrayivu. Idume ngokuqina nokuthembeka kwayo, okuvamise ukusetshenziswa ekukhiqizeni nasekucubunguleni i-automation.
I-PROFIBUS isebenzisa ukuxhumana kwe-serial okusekelwe kungqimba olubonakalayo lwe-RS-485. Isekela amanani edatha afika ku-12 Mbps futhi ifanele ulayini noma webhasi topology. Ifaneleka kakhulu ezindaweni ezidinga ukuxhumana okunqunyiwe.
2. Yini i-PROFINET?
I-PROFINET iyiphrothokholi yokuxhumana esekwe ku-Ethernet eyakhiwe ngabakwa-PROFIBUS kanye ne-PROFINET International (PI). Idizayinelwe ngokuqondile ukushintshaniswa kwedatha yejubane eliphezulu, yesikhathi sangempela kumanethiwekhi ezimboni zanamuhla, esekela imisebenzi eyinkimbinkimbi ezenzakalelayo.
I-PROFINET isekelwe kubuchwepheshe obujwayelekile be-Ethernet futhi isekela amanani edatha ukusuka ku-100 Mbps ukuya kuzivinini ze-Gigabit. I-topology yayo yenethiwekhi eguquguqukayo ihlanganisa inkanyezi, umugqa, indandatho, noma izakhiwo zesihlahla. Ilungele ukusebenza okuzenzakalelayo okuphezulu, amarobhothi, nokulawula ukunyakaza.
3. PROFIBUS Cables
Njengoba i-PROFIBUS incike ekusayineni okuhlukile kwe-serial, ukufakwa kwekhebula kufanele kunciphise ukuphazamiseka kwe-electromagnetic (EMI) futhi kugcine ubuqotho besignali. Izicaciso ezijwayelekile zekhebula le-PROFIBUS zifaka phakathiipheya elisontiwe elivikelekile (STP) or ipheya esontekile engavikelekile (UTP)nge-impedance ye-100-120 ohms. Izintambo ezivikelekile ziyanconywa ezindaweni zezimboni ezine-EMI ephezulu. Ngamazinga aphansi e-baud, ubude bekhebula bungafinyelela kumamitha angu-1200. Izixhumi kufanele zibe yizinhlobo ze-M12, M8, noma i-screw-terminal.
Sebenzisa izintambo ezinezitifiketi ze-PROFIBUS ukuze uqinisekise ukuhambisana, izihlangu eziphansi ngokufanelekile ukuze unciphise umsindo, nokugcina umzila ofanele wekhebula ukuze ugweme ukuphazamiseka.
4. PROFINET Cables
I-PROFINET isebenzisa ikhebula ye-Ethernet evamile, izintambo zenethiwekhi yezohwebo ezisetshenziswayo. Ukukhethwa kwekhebula ngendlela efanele kuqinisekisa ukuxhumana okushesha, okuthembekile, ikakhulukazi ezindaweni eziqinile zezimboni.
Izicaciso ezijwayelekile zekhebula le-PROFINET yi-Cat5e, i-Cat6, noma ngaphezulu (okungcono ivikelwe ngokwezinga lezimboni). Ukuze uvikeleke, sebenzisa ipheya esontekile evikelekile (STP noma i-S/FTP) ezindaweni ezinomsindo. Izixhumi ezinconyiwe ziyi-industrial-standard RJ45 Ethernet. Ingxenye yekhebula ngayinye akufanele idlule amamitha ayi-100; amabanga amade adinga amaswishi noma iziphindaphinda.
PROFINET Izindlela Ezinhle Kakhulu:Sebenzisa izintambo ze-Ethernet zezinga lezimboni eziklanyelwe izindawo ezinokhahlo; qinisekisa isisekelo esifanele nesivikelo; sebenzisa amaswishi enethiwekhi yezimboni ukuze unwebe noma uhlukanise inethiwekhi.
5. Iyiphi Ikhebula Okufanele Uyikhethe?
Sebenzisa izintambo ze-PROFIBUS:
-
Okwamasistimu endabuko noma izinhlelo zokusebenza zokuxhumana ze-serial
-
Ezimweni ezinokuphazamiseka okuncane kozibuthe
-
Lapho kubiza, ukuxhumana kwe-serial okuthembekile kwanele
-
Okwekhebula elifushane ligijima ngaphakathi kwemishini noma amakhabethe okulawula
Sebenzisa izintambo ze-PROFINET:
-
Ngezinhlelo zokusebenza ezinesivinini esikhulu, ezinomkhawulokudonsa ophezulu
-
Ezimweni ze-EMI ephezulu ezidinga amakhebuli e-Ethernet avikelwe
-
Ukuze uthole ama-topology enethiwekhi aguquguqukayo, angalawuleki
-
Lapho ihlanganisa namadivayisi esimanje asekelwe ku-Ethernet nokwakha amasistimu obufakazi besikhathi esizayo
6. Amathiphu Wokufaka Wokuxhumana Okuthembekile
-
Ukuvikela Okufanelekile:Sebenzisa okuvikelekileizintambofuthi uqinisekise ukuthi izihlangu zibekwe phansi ngendlela efanele.
-
Umzila wekhebula:Gcina izintambo zokuxhumana zikude nezintambo zikagesi nemithombo yokuphazamiseka.
-
Izixhumi namatheminali:Sebenzisa izixhumi zezinga lezimboni futhi uqinisekise ukuthi amatheminali avikelekile.
-
Ukuhlukaniswa:Dizayina amanethiwekhi ukuze unciphise ubude besegimenti futhi ugweme amalophu angadingekile.
-
Ukucatshangelwa kwemvelo:Khetha izintambo ezilinganiselwe izinga lokushisa, ukuchayeka kumakhemikhali, kanye nengcindezi yemishini endaweni.
Zombili izintambo ze-PROFIBUS ne-PROFINET zidlala izindima ezibucayi kodwa zenzelwe izinhlelo zokusebenza ezithile. I-PROFIBUS imele inqubo ye-fieldbus futhi isiphenduke into ethembekile, ikakhulukazi ezimbonini zezinqubo zendabuko ezithembele ekwakhiweni kwayo okuqinile. Lezi zindawo ngokuvamile zidinga ukuzinza nokuvumelana futhi zizuze ekhonweni le-PROFIBUS lokugcina ukuxhumana okuthembekile kumabanga amade kanye nokuhlelwa kwenethiwekhi okuyinkimbinkimbi.
Lapho ukhetha, cabangela ingqalasizinda yakho, indawo ezungezile, nezinjongo zesikhathi esizayo. Khetha izixazululo ezihlala isikhathi eside, ezisebenza kahle kakhulu, nezithembekile ngisho nangaphansi kwezimo ezinzima kakhulu.
