I-MODBUS RTU manje iyahambisana nokuxhumana kwe-Ethernet
Isandulelo: Isidingo se-Industrial Ethernet Esikhathini Semboni 4.0
Imboni 4.0 iyinkathi yobuhlakani obutholakala ngokusebenzisa ubuchwepheshe bolwazi. Izimboni ezihlakaniphile zingenye yezimo eziyinhloko zokusetshenziswa kwe-Industry 4.0, zisebenzisa amadivayisi ahlakaniphile kanye nobuchwepheshe bolwazi ukuze kufezwe ukuzenzekela, ubuhlakani, kanye nokuguquguquka ezinqubweni zokukhiqiza nokuphatha. Ukuxhumanisa imishini ehlukahlukene yokukhiqiza, i-plcama-s, izinzwa, izinsimbi, amarobhothi ezimboni, amathuluzi omshini we-CNC, namanye amadivayisi ngaphakathi kwefektri ehlakaniphile ukufeza ukuxhumana kwamadivayisi nokwabelana ngedatha, ngaleyo ndlela kufezwe umsebenzi wokubambisana kanye nokuphathwa okuhle, kusiza ukuthuthukisa ukusebenza kahle kokukhiqiza, ukunciphisa izindleko zokukhiqiza, kanye nokuthuthukisa ikhwalithi yomkhiqizo.
Ungafinyelela kanjani ukuxhumana kwezimboni futhi unike amandla i-MODBUS RTU ukuxhumana ngamachweba enethiwekhi?
Kuyini i-Modbus RTU?
I-Modbus RTU iyiphrothokholi yokuxhumana elandelanayo esetshenziselwa ukuxhumanisa amadivayisi kagesi ezimbonini afana nabalawuli be-logic abahlelekayo (ama-PLC), izinzwa, ama-actuator, njll. Le phrothokholi ichaza isakhiwo semiyalezo esivumela ukuxhumana phakathi kwala madivayisi ukufeza ukudluliselwa kwedatha kanye nokusebenza kwemiyalelo yokulawula. Izici eziyinhloko zephrothokholi ye-Modbus RTU zifaka:
·Ukuxhumana okulandelanayo: Kusebenzisa indlela yokuxhumana okulandelanayo futhi kufanelekile ukuxhumana phakathi kwamadivayisi ngokuxhumana okungokoqobo njenge-RS-232, RS-485, njll.
·Imodi yesigqila esiyinhloko: Ukuxhumana kusekelwe ekwakhiweni kwe-master-slave, lapho idivayisi eyodwa isebenza njengenkosi futhi inesibopho sokuqala izicelo zokuxhumana, kuyilapho amanye amadivayisi esebenza njengezigqila futhi ephendula izicelo zenkosi.
·Isakhiwo somlayezo: sichaza isakhiwo somlayezo, okuhlanganisa ikheli ledivayisi, ikhodi yomsebenzi, idatha, kanye nokuhlola amaphutha, ukuqinisekisa ukudluliselwa kanye nokucutshungulwa kolwazi okulungile.
·Ukuhambisana okubanzi: Iphrothokholi ye-Modbus RTU isetshenziswa kabanzi ezinhlelweni ezahlukene zokwenza izinto ngokuzenzakalela kwezimboni ngenxa yokuvuleka kwayo kanye nokulula kokusetshenziswa.
Umehluko Phakathi kwe-Modbus RTU ne-Modbus TCP
I-Modbus RTU kanye ne-Modbus TCP ziyizindlela ezimbili zokuxhumana ezihlukene, ezinomehluko ngesivinini sokudlulisa idatha, izindlela zokudlulisa idatha, kanye nezimo ezifanele. I-Modbus RTU ifaneleka kakhulu ekudlulisweni kwedatha phakathi kwamadivayisi akude, kanti i-Modbus TCP ifaneleka kakhulu ekudlulisweni kwedatha ngesikhathi sangempela phakathi kwamadivayisi.
Ukuzenzakalela kwezimboni
Ngokuthuthuka okuqhubekayo kokuzenzakalela kwezimboni, i-Modbus RTU isetshenziswa kabanzi emishinini eyahlukahlukene yokuzenzakalela kwezimboni, njenge-PLC, izinzwa, njll. Nge-Modbus RTU, singafinyelela ukuqapha nokulawula okukude, sithuthukise ukusebenza kahle kokukhiqiza.
I-inthanethi Yezinto
Ukuthuthukiswa kobuchwepheshe be-IoT kuhlinzeke ngezimo ezengeziwe zohlelo lokusebenza lwe-Modbus RTU. Ngokuxhumanisa amadivayisi ahlukahlukene kunethiwekhi, singafinyelela ukuqapha nokulawula amadivayisi kude, sithuthukise izinga lawo lobuhlakani.
Ezinye izinkambu
Ngaphezu kokwenza izinto ngokuzenzakalela kwezimboni kanye ne-Intanethi Yezinto, i-Modbus RTU ingasetshenziswa nakweminye imikhakha efana namadolobha ahlakaniphile, ezokuthutha ezihlakaniphile, amakhaya ahlakaniphile, njll.
Ingabe i-MODBUS RTU ingaxhumana futhi ngamachweba e-Ethernet?
Ukuzenzakalela kwezimboni
Kunamadivayisi ahlukahlukene avuthiwe emakethe angaguqula i-MODBUS RTU (i-serial port) ibe yi-MODBUS TCP (i-Ethernet interface) yokuxhumana, okuvame ukubizwa ngokuthi ama-protocol converters, ama-gateways, noma amaseva e-serial. Nazi ezinye izinhlobo zemikhiqizo ezivamile:
1. Isango Lephrothokholi yeModbus: Lawa masango asekela amaphrothokholi amaningi eModbus, kufaka phakathi iModbus TCP/RTU/ASCII, futhi anamakhono okuguqula amaphrothokholi.
2. Isiguquli Sephrothokholi: Lolu hlobo lwedivayisi lungaguqula iphrothokholi ye-MODBUS RTU ibe yiphrothokholi ye-MODBUS TCP/IP, okuvumela ukudluliswa kwedatha nge-Ethernet.
3. Iseva ye-serial port: Iseva ye-serial port iyidivayisi engaguqula ukuxhumana kwe-serial ibe ukuxhumana kwenethiwekhi, okuvumela amadivayisi e-MODBUS RTU ukuthi axhumane ngenethiwekhi.
4. Isiguquli Sesixhumi: Amanye ama-converter esixhumi ayakwazi ukuguqula phakathi kwe-Modbus RTU kanye ne-Modbus TCP.
5. Isango le-IoT Yezimboni: Lawa madivayisi awasekeli nje kuphela ukuguqulwa kwephrothokholi, kodwa futhi ahlinzeka ngemisebenzi eyengeziwe ye-IoT, njengokuqoqwa kwedatha, ukubalwa kwe-edge kanye nokuxhumeka kwamafu. Isixazululo esisekelwe epulatifomu yokuphatha ikhodi ephansi okukhulunywe ngayo kungenza inqubo yokuthuthukisa ibe lula, sinciphise izindleko, futhi sithuthukise ukusebenza kahle kwentuthuko.
Umdwebo Wokuxhumana
Ukuze kufezwe ukuxhumana kwe-Modbus RTU ngamachweba e-Ethernet, i-converter ye-serial kuya ku-Ethernet ivame ukudingeka.
Kulo mdwebo, idivayisi elandelanayo ixhunywe ku-converter nge-interface ye-RS-485. I-converter iguqula amaphakethe ephrothokholi ye-Modbus RTU abe yifomethi ye-Modbus TCP/IP bese iwathumela kunethiwekhi nge-Ethernet. Ngemva kokuthola idatha, idivayisi eyamukelayo yenza imisebenzi noma izimpendulo ezifanayo.
Isiphetho
I-Modbus RTU inezinzuzo eziningi zokudlulisela kude, okuhlanganisa izindleko eziphansi, ukusebenza kahle kokudlulisela okuphezulu, kanye nekhono eliqinile lokulwa nokuphazamiseka. Esikhathini esizayo, ngentuthuko eqhubekayo yobuchwepheshe obufana ne-Internet of Things kanye nekhodi ephansi, inhlanganisela yamachweba e-Modbus RTU kanye ne-Ethernet izosetshenziswa kabanzi, inikeze ukwesekwa okuqinile kokuzenzakalelayo kwezimboni kanye nobuhlakani.
Esikhathini esizayo, kuzoba namadivayisi e-IoT amaningi, futhi ukudluliswa kwedatha kuzoba yinkinga ebalulekile kuzinhlelo zokusebenza ze-IoT. Ngokuhlanganisa i-Modbus RTU namachweba e-Ethernet, ukudluliswa kwedatha kwamadivayisi e-IoT ahlukahlukene kungafinyelelwa, kuhlangatshezwane nezidingo zokudluliswa kwedatha zezimo ezahlukene. Okwamanje, ngokuthuthukiswa kwekhodi ephansi kanye nobunye ubuchwepheshe, ukudluliswa kwedatha kuzoba lula, kusheshe, futhi kusebenze kahle. Ngakho-ke, ukuhlanganiswa kwamachweba e-Modbus RTU kanye ne-Ethernet kuzodlala indima ebalulekile ezinhlelweni zokusebenza ze-IoT zesikhathi esizayo futhi kube nethuba elibanzi lokusebenzisa.
