I-MODBUS RTU sele ihambisana nokukhulumisana nge-Ethernet
Isandulela: Ukufunwa kwe-Ethernet yamabubulo ngesikhathi se-Industri 4.0
I-Industri 4.0 yisikhathi sokuhlakanipha esizuzwe ngokusetjenziswa kwethekhnoloji yolwazi. Amafemu ahlakaniphileko ngenye yezinto eziqakathekileko zokusetjenziswa kwe-Industri 4.0, esebenzisa amadivayisi ahlakaniphileko kanye nethekhnoloji yelwazi ukufikelela ukuzenzakalela, ukuhlakanipha, nokutjhuguluka eenkambisweni zokukhiqiza nezokulawula. Ukuhlanganisa iinsetjenziswa ezihlukahlukeneko zokukhiqiza, plcs, iinzwa, iinsetjenziswa, amarobhothi wezebubulo, amathulusi wemitjhini ye-CNC, namanye amadivayisi ngaphakathi kwefemu ehlakaniphileko ukufezekisa ukusebenzisana kwamadivayisi nokwabelana ngedatha, ngaleyo ndlela kuzuzwe umsebenzi ngokubambisana nokuphathwa okuhle, kusiza ukuthuthukisa ukusebenza kuhle kokukhiqiza, ukwehlisa iindleko zokukhiqiza, nokuthuthukisa ikhwalithi yomkhiqizo.
Kungenziwa njani ukufezekisa ukuhlangana kwamabubulo begodu wenze i-MODBUS RTU ikwazi ukukhulumisana ngamachweba wenethiwekhi?
Khuyini i-Modbus RTU?
I-Modbus RTU yiphrothokholi yokukhulumisana esetjenziselwa ukuhlanganisa amadivayisi we-elekthronikhi webubulo afana nama-PLC, iinzwa, ama-actuator, njll. Iphrothokholi le ihlathulula isakhiwo somlayezo esivumela ukukhulumisana hlangana namadivayisi la ukufikelela ukudluliswa kwedatha nokulawula ukusebenza kwemiyalo. Iimpawu ezikulu zephrothokholi ye-Modbus RTU zifaka hlangana:
·Ukukhulumisana ngokulandelana: Kwamukela indlela yokukhulumisana ngokulandelana begodu ilungele ukukhulumisana hlangana namadivayisi ngokusebenzisa ukuxhumana okuphathekako okufana ne-RS-232, RS-485, njll.
·Imodi yesigqila esikhulu: Ukukhulumisana kusekelwe ekwakhiweni kwesigqila esikhulu, lapho idivayisi eyodwa isebenza njengekosi begodu inesibopho sokuthoma iimbawo zokuthintana, lokha ezinye iinsetjenziswa zisebenza njengeengqila begodu ziphendula iimbawo zenkosi.
·Isakhiwo somlayezo: sihlathulula isakhiwo somlayezo, kufaka hlangana ikheli ledivayisi, ikhodi yomsebenzi, idatha, nokuhlola amaphutha, ukuqinisekisa ukudluliswa nokusetjenziswa okufaneleko kwelwazi.
·Ukuvumelana okubanzi: Iphrothokholi ye-Modbus RTU isetjenziswa khulu eenhlelweni ezihlukahlukeneko zokuzenzakalela zebubulo ngebanga lokuvuleka kwayo nokulula ukuyisebenzisa.
Umehluko phakathi kwe-Modbus RTU ne-Modbus TCP
I-Modbus RTU ne-Modbus TCP ziindlela ezimbili ezihlukileko zokuthintana, ezinomehluko ngesivinini sokudlulisa idatha, iindlela zokudlulisa idatha, kanye nezimo ezisebenzako. I-Modbus RTU ilungele ukudluliswa kwedatha hlangana namadivayisi akude, ngesikhathi i-Modbus TCP ilungele ukudluliswa kwedatha ngesikhathi sangempela hlangana namadivayisi.
Ukuzenzakalela kwezebubulo
Ngokuthuthukiswa okuragela phambili kokuzenzakalela kwezebubulo, i-Modbus RTU isetjenziswa khulu emitjhini ehlukahlukeneko yokuzenzakalela kwezebubulo, njenge-PLC, iinzwa, njll. Nge-Modbus RTU, singakghona ukufikelela ukutjheja nokulawula okude, okwenza ngcono ukusebenza kuhle kokukhiqiza.
I-Inthanethi yezinto
Ukuthuthukiswa kwethekhnoloji ye-IoT nakho kunikele ngezimo ezinengi zokusebenzisa i-Modbus RTU. Ngokuhlanganisa amadivayisi ahlukahlukeneko kunethiwekhi, singafinyelela ukutjheja nokulawulwa kwamadivayisi, okwenza ngcono izinga lobuhlakani bawo.
Ezinye iindawo
Ngaphezu kokuzenzakalela kwezebubulo kanye ne-Inthanethi yezinto, i-Modbus RTU ingasetjenziswa kezinye iinkalo ezifana namadorobha ahlakaniphileko, ukuthutha okuhlakaniphileko, amakhaya ahlakaniphileko, njll.
Ingabe i-MODBUS RTU nayo ingaxhumana ngamachweba we-Ethernet?
Ukuzenzakalela kwezebubulo
Kunamadivayisi ahlukahlukeneko avuthiweko emakethe angaguqula i-MODBUS RTU (i-serial port) ibe yi-MODBUS TCP (i-Ethernet interface) malungana nokukhulumisana, okuvamise ukubizwa ngokuthi ziinguquli zephrothokholi, amasango, nofana amaseva we-serial. Nazi ezinye iinhlobo zemikhiqizo ezijayelekileko:
1. Isango lePhrothokholi ye-Modbus: Amasango la asekela amaphrothokholi amanengi we-Modbus, kufaka hlangana i-Modbus TCP/RTU/ASCII, begodu anamandla wokutjhugulula iphrothokholi.
2. Isitjhugululi sephrothokholi: Umhlobo lo wedivayisi ungatjhugulula iphrothokholi ye-MODBUS RTU ibe yiphrothokholi ye-MODBUS TCP/IP, okwenza bona idatha ithunyelwe nge-Ethernet.
3. Iseva ye-serial port: Iseva ye-serial port yidivayisi engaguqula ukukhulumisana kwe-serial kube ukukhulumisana kwenethiwekhi, okuvumela amadivayisi we-MODBUS RTU ukuthi akhulumisane ngenethiwekhi.
4. I-Interface Converter: Abanye abatjhugululi be-interface bayakghona ukutjhugulula hlangana ne-Modbus RTU ne-Modbus TCP.
5. Isango le-IoT yamabubulo: Amadivayisi la awasekeli ukutjhugulula iphrothokholi kwaphela, kodwana anikela neminye imisebenzi ye-IoT, njengokubuthelela idatha, ukusebenzisa ikhomphyutha emaphethelweni nokuxhumana kwefu. Isisombululo esisekelwe epulatifomu yokuphatha ikhodi ephasi ekhulunywe ku- kungenza lula ikambiso yokuthuthukisa, yehlise iindleko, begodu yenze ngcono ukusebenza kuhle kokuthuthukisa.
Umdwebo wokukhulumisana
Ukufikelela ukukhulumisana kwe-Modbus RTU ngama-port we-Ethernet, umtjhugululi we-serial ukuya ku-Ethernet uvamise ukutlhogeka.
Emdwebeni lo, idivayisi ye-serial ixhunywe kumtjhugululi nge-RS-485. Umtjhugululi utjhugulula amaphakheji wephrothokholi ye-Modbus RTU abe yifomethi ye-Modbus TCP/IP bese uwathumela kunethiwekhi nge-Ethernet. Ngemva kokwamukela idatha, idivayisi eyamukelako yenza imisebenzi ehambelanako nofana iimpendulo.
Isiphetho
I-Modbus RTU inezinzuzo ezinengi zokudlulisa kude, okufaka hlangana iindleko eziphasi, ukusebenza kuhle kokudlulisa, kanye nekghono elinamandla lokulwisana nokuphazamiseka. Esikhathini esizako, ngokuthuthukiswa okuragelako kwethekhnoloji efana ne-Inthanethi yezinto kanye nekhodi ephasi, ukuhlanganiswa kwe-Modbus RTU kanye namachweba we-Ethernet kuzokusetjenziswa khulu, kuzokunikela isekelo eliqinileko lokuzenzakalela kwezebubulo nokuhlakanipha.
Esikhathini esizako, kuzokuba namadivayisi amanengi we-IoT, begodu ukudluliswa kwedatha kuzokuba yinto eqakathekileko eensetjenzisweni ze-IoT. Ngokuhlanganisa i-Modbus RTU namachweba we-Ethernet, ukudluliswa kwedatha yamadivayisi ahlukahlukeneko we-IoT kungafezwa, ukuhlangabezana neendingo zokudluliswa kwedatha zezimo ezihlukahlukeneko. Khatheso, ngokuthuthukiswa kwekhodi ephasi namanye amathekhnoloji, ukudluliswa kwedatha kuzokuba lula, kube msinyana, begodu kube lula. Ngalokho-ke, ukuhlanganiswa kwe-Modbus RTU kanye namachweba we-Ethernet kuzokudlala indima eqakathekileko eensetjenzisweni ze-IoT zesikhathi esizako begodu kube nethemba lokusetjenziswa elibanzi
