I-MODBUS RTU manje iyahambisana nekuchumana kwe-Ethernet
Sendvulo: Sidzingo Se-Ethernet Yetimboni Esikhatsini Semboni 4.0
Imboni 4.0 sikhatsi sebuhlakani lesizuzwa ngekusebentisa tebuchwepheshe belwati. Emafemu lahlakaniphile ngulenye yetindzawo letiyinhloko tekusebenta teMboni 4.0, asebentisa tintfo letihlakaniphile kanye nebuchwepheshe belwati kute kuzuzwe kusebenta ngekuzenzakalela, kuhlakanipha, kanye nekugucugucuka etinchubeni tekukhicita nekulawula. Kuhlanganisa imishini leyehlukahlukene yekukhicita, plcs, tinzwa, tintfo tekusebenta, emarobhothi etimboni, emathuluzi emishini ye-CNC, kanye naletinye tintfo ngaphakatsi kwefemu lehlakaniphile kute kuzuzwe inethiwekhi yetintfo tekusebenta kanye nekwabelana ngemininingwane, ngaleyo ndlela kuzuzwe umsebenti wekubambisana kanye nekulawula lokulungisiwe, kusita kwenta ncono kusebenta kahle kwekukhicita, kunciphisa tindleko tekukhicita, kanye nekutfutfukisa lizinga lemkhicito.
Indlela yekufeza kuhlanganiswa kwetimboni kanye nekuniketa i-MODBUS RTU emandla ekukhulumisana ngemachweba enethiwekhi?
Yini iModbus RTU ?
Modbus RTU yindlela yekuchumana lelandzelanako lesetjentiselwa kuxhumanisa tintfo te-elekthronikhi tetimboni letifana nebalawuli be-logic labahlelekako (ema-PLC), tinzwa, ema-actuators, njll. Timphawu letiyinhloko te-Modbus RTU protocol tifaka ekhatsi:
· ·Kukhulumisana ngekulandzelana: Kutsatsa indlela yekuchumana ngekulandzelana futsi kulungele kukhulumisana emkhatsini wetintfo ngekuxhumana lokubonakalako njenge-RS-232, RS-485, njll.
· ·Imodi yesigcili lesikhulu: Kukhulumisana kususelwa ekwakhiweni kwesigcili lesikhulu, lapho khona intfo yinye isebenta njengenkhosi futsi inesibopho sekucala ticelo tekuchumana, kantsi letinye tintfo tisebenta njengetigcili futsi tiphendvula ticelo tenkhosi. .
· ·Isakhiwo semlayeto: sichaza sakhiwo semlayeto, kufaka ekhatsi likheli ledivayisi, ikhodi yemsebenti, idatha, kanye nekuhlola emaphutsa, kucinisekisa kudluliselwa lokufanele kanye nekucubungula lwati. .
· ·Kuhambisana lokubanti: I-Modbus RTU protocol isetjentiswa kakhulu etinhlelo letehlukene tekusebenta ngekuzenzakalela kwetimboni ngenca yekuvuleka kwayo kanye nekusebenta kwayo kalula.
Umehluko Emkhatsini We-Modbus RTU Ne-Modbus TCP
Modbus RTU kanye Modbus TCP tindlela letimbili letehlukene tekuchumana, nge umehluko ngesivinini sekudluliswa kwemininingwane, tindlela tekudluliswa kwemininingwane, kanye netindzaba letisebentako. I-Modbus RTU ilungele kakhulu kudluliswa kwemininingwane emkhatsini wemadivayisi lakhashane, kantsi i-Modbus TCP ilungele kakhulu kudluliswa kwemininingwane ngesikhatsi sangempela emkhatsini wetintfo.
Kusebenta ngekuzenzakalela kwetimboni
Ngekutfutfukiswa lokuchubekako kwekusebenta kwetimboni, i-Modbus RTU isetjentiswa kakhulu emishinini leyehlukahlukene yekusebenta kwetimboni, njenge-PLC, tinzwa, njll Nge-Modbus RTU, singafinyelela kugadza nekulawula lokukude, kwenta ncono kusebenta kahle kwekukhicita.
I-Inthanethi Yetintfo
Kutfutfukiswa kwebuchwepheshe be-IoT kuphindze futsi kwaniketa tindzawo letinyenti tekusebenta te-Modbus RTU. Ngekuxhumanisa emadivayisi lehlukahlukene kunethiwekhi, singafinyelela kugadza lokukhashane kanye nekulawula emadivayisi, kwenta ncono lizinga labo lebuhlakani.
Letinye tindzawo
Ngetulu kwekusebenta ngekuzenzakalela kwetimboni kanye ne-Inthanethi Yetintfo, i-Modbus RTU ingaphindze isetjentiswe kuletinye tindzawo letifana nemadolobha lahlakaniphile, tekutfutsa letihlakaniphile, emakhaya lahlakaniphile, njll.
Ingabe i-MODBUS RTU ingaphindze ikhulume ngemachweba e-Ethernet?
Kusebenta ngekuzenzakalela kwetimboni
Kukhona tintfo letehlukahlukene letivutsiwe emakethe letingagucula i-MODBUS RTU (itheku lelandzelanako) ibe yi-MODBUS TCP (i-Ethernet interface) yekuchumana, levame kubitwa ngekutsi tiguculeli te-protocol, emasango, noma emaseva lalandzelanako. Nati letinye tinhlobo temkhicito letivamile:
1. Lisango Lephrothokholi Ye-Modbus: Lamasango asekela imigomo leminyenti ye-Modbus, kufaka ekhatsi i-Modbus TCP / RTU / ASCII, futsi inemandla ekugucula iphrothokholi.
2. Umguculi Wephrothokholi: Loluhlobo lwedivayisi lungagucula iphrothokholi ye-MODBUS RTU ibe yiphrothokholi ye-MODBUS TCP / IP, kuniketa emandla ekudluliselwa kwemininingwane nge-Ethernet.
3. Iseva ye-serial port: Iseva ye-serial port yintfo lengagucula kuchumana kwe-serial kube kuchumana kwenethiwekhi, kuvumela tintfo te-MODBUS RTU kutsi tikhulumisane ngenethiwekhi.
4. Umguculi wesikhombisi: Labanye baguculi besikhombisi bayakhona kugucula emkhatsini weModbus RTU neModbus TCP.
5. Industrial IoT gateway: Lamadivayisi akagcini nje ngekusekela kuguculwa kwephrothokholi, kepha aniketa imisebenti lengetiwe ye-IoT, njengekugcogcwa kwemininingwane, kusebentisa emakhompyutha emphethweni kanye nekuxhumana kwemafu. Sisombululo lesisekelwe enkhundleni yekulawula ikhodi lephansi leshiwo ku ingawenta inchubo yekutfutfukisa ibe lula, inciphise tindleko, futsi yente ncono kusebenta kahle kwekutfutfukisa.
Umdvwebo Wekuchumana
Kuze ufinyelele kukhulumisana kwe-Modbus RTU ngekusebentisa emachweba e-Ethernet, kuvame kudzingeka umguquli we-serial kuya ku-Ethernet.
Kulomdvwebo, idivayisi serial ixhunywe umguculi nge RS-485 interface. Umguculeli ugucula emaphakethe ephrothokholi ye-Modbus RTU abe yifomethi ye-Modbus TCP / IP bese uyawatfumela kunethiwekhi nge-Ethernet. Ngemuva kwekutfola idatha, idivayisi leyamukelako yenta imisebenti lehambisanako noma timphendvulo.
Siphetfo
Modbus RTU unetinzuzo letinyenti tekudluliswa lokukhashane, kufaka ekhatsi tindleko letiphansi, kusebenta kahle kwekudluliswa lokusezingeni leliphakeme, kanye nemandla lacinile ekulwa nekuphazamiseka. Esikhatsini lesitako, ngekutfutfukiswa lokuchubekako kwetebucwepheshe letifana ne-Inthanethi Yetintfo kanye nekhodi lephansi, kuhlanganiswa kwemachweba e-Modbus RTU kanye ne-Ethernet kutawusetjentiswa kakhulu, kunikete kusekelwa lokucinile kwekusebenta ngekuzenzakalela kwetimboni kanye nebuhlakani.
Esikhatsini lesitako, kutawuba netintfo letinyenti te-IoT, futsi kudluliselwa kwemininingwane kutawuba yinkinga lebalulekile yetinhlelo tekusebenta te-IoT. Ngekuhlanganisa iModbus RTU nemachweba e-Ethernet, kudluliselwa kwemininingwane yetintfo letehlukene te-IoT kungafezeka, kuhlangabetana netidzingo tekudluliselwa kwemininingwane yetindzawo letehlukene. Ngaleso sikhatsi, ngekutfutfukiswa kwekhodi lephansi kanye nalobunye bucwepheshe, kudluliselwa kwemininingwane kutawuba melula, kusheshe, futsi kusebente kahle. Ngako-ke, inhlanganisela ye-Modbus RTU kanye nemachweba e-Ethernet itawudlala indzima lebalulekile ekusebentiseni kwe-IoT yesikhatsi lesitako futsi ibe nelitsemba lelibanti lekusebentisa .
