MODBUS RTU ubu ikorana n'itumanaho rya Ethernet
Intangiriro: Ubusabe bwa Ethernet y'inganda mu gihe cy'inganda 4.0
Inganda 4.0 ni igihe cy'ubwenge bugerwaho binyuze mu ikoreshwa ry'ikoranabuhanga mu itumanaho. Inganda zikoresha ubwenge ni zimwe mu ngingo z'ingenzi zikoreshwa mu ikoranabuhanga mu ikoranabuhanga mu itumanaho, zikoresha ibikoresho by'ubwenge n'ikoranabuhanga mu itumanaho kugira ngo zigere ku buryo bwikora, ubwenge, no koroshya ibikorwa byo gukora no gucunga. Guhuza ibikoresho bitandukanye byo gukora, plcs, sensors, ibikoresho, robots zo mu nganda, ibikoresho by'imashini za CNC, n'ibindi bikoresho biri mu ruganda rukora ibikoresho bigezweho kugira ngo habeho imikoranire y'ibikoresho no gusangira amakuru, bityo habeho ubufatanye n'imicungire myiza, bifasha kunoza imikorere myiza y'umusaruro, kugabanya ikiguzi cy'umusaruro, no kongera ireme ry'umusaruro.
Ni gute wagera ku mikoranire y’inganda no gutuma MODBUS RTU ibasha kuvugana binyuze mu miyoboro y’itumanaho?
Modbus RTU ni iki?
Modbus RTU ni protocole y'itumanaho ikoreshwa mu guhuza ibikoresho by'ikoranabuhanga byo mu nganda nka programmable logic controllers (PLCs), sensors, actuators, nibindi. Iyi protocole isobanura imiterere y'ubutumwa yemerera itumanaho hagati y'ibi bikoresho kugera ku kohereza amakuru no gushyira mu bikorwa amabwiriza yo kugenzura. Ibintu by'ingenzi bigize protocole ya Modbus RTU birimo:
·Itumanaho ry'uruhererekane: Rikoresha uburyo bw'itumanaho ry'uruhererekane kandi rikwiriye itumanaho hagati y'ibikoresho binyuze mu guhuza ibintu nk'ibi: RS-232, RS-485, nibindi.
·Uburyo bw'umugaragu w'umuhanga: Itumanaho rishingiye ku buryo bw'umushumba w'umuhanga, aho igikoresho kimwe gikora nk'umuyobozi kandi kikaba gishinzwe gutangiza ibyifuzo by'itumanaho, mu gihe ibindi bikoresho bikora nk'abacakara kandi bigasubiza ibyifuzo bya shebuja.
·Imiterere y'ubutumwa: isobanura imiterere y'ubutumwa, harimo aderesi y'igikoresho, kode y'imikorere, amakuru, no kugenzura amakosa, kugira ngo hamenyekane ko amakuru yoherezwa neza kandi agatunganywa neza.
·Guhuza ibintu byinshi: Porogaramu ya Modbus RTU ikoreshwa cyane muri sisitemu zitandukanye z’ikoranabuhanga mu nganda bitewe n’uko ifunguye kandi yoroshye kuyishyira mu bikorwa.
Itandukaniro riri hagati ya Modbus RTU na Modbus TCP
Modbus RTU na Modbus TCP ni uburyo bubiri butandukanye bwo gutumanaho, bufite itandukaniro mu muvuduko wo kohereza amakuru, uburyo bwo kohereza amakuru, n'ibintu bifatika. Modbus RTU ikwiriye cyane mu kohereza amakuru hagati y'ibikoresho biri kure, mu gihe Modbus TCP ikwiriye cyane mu kohereza amakuru mu buryo bwihuse hagati y'ibikoresho.
Ikoranabuhanga mu by'ikoranabuhanga
Bitewe n’iterambere rihoraho ry’imikorere y’inganda, Modbus RTU ikoreshwa cyane mu bikoresho bitandukanye by’imikorere y’inganda, nka PLC, sensors, nibindi. Binyuze muri Modbus RTU, dushobora kugera ku igenzura no kugenzura kure, tukongera imikorere myiza y’umusaruro.
interineti y'ibintu
Iterambere ry'ikoranabuhanga rya IoT ryanatanze uburyo bwinshi bwo gukoresha Modbus RTU. Dukoresheje uburyo bwo guhuza ibikoresho bitandukanye n'umuyoboro, dushobora kugera ku kugenzura no kugenzura ibikoresho biri kure, tukongera urwego rw'ubwenge bwabyo.
Izindi nganda
Uretse ikoranabuhanga mu nganda na interineti y’ibintu, Modbus RTU ishobora no gukoreshwa mu zindi nzego nko mu mijyi igezweho, ubwikorezi bugezweho, amazu agezweho, nibindi.
Ese MODBUS RTU ishobora no gutumanaho binyuze kuri za ports za Ethernet?
Ikoranabuhanga mu by'ikoranabuhanga
Hari ibikoresho bitandukanye bikuze ku isoko bishobora guhindura MODBUS RTU (serial port) muri MODBUS TCP (Ethernet interface) kugira ngo bikoreshwe mu itumanaho, bizwi nka protocole converters, gateways, cyangwa serial servers. Dore ubwoko bumwe na bumwe bw'ibicuruzwa busanzwe:
1. Modbus Protocol Gateway: Izi nzira zishyigikira protocole nyinshi za Modbus, harimo Modbus TCP/RTU/ASCII, kandi zifite ubushobozi bwo guhindura protocole.
2. Umuhinduzi wa Porotokole: Ubu bwoko bw'igikoresho bushobora guhindura protocole ya MODBUS RTU ikaba protocole ya MODBUS TCP / IP, bigatuma amakuru yoherezwa kuri Ethernet.
3. Seriveri ya poriteri y'uruhererekane: Seriveri ya poriteri y'uruhererekane ni igikoresho gishobora guhindura itumanaho rya poriteri mu itumanaho rya interineti, bigatuma ibikoresho bya MODBUS RTU bikorana binyuze kuri interineti.
4. Interface Converter: Hari abahindura interface bashobora guhindura hagati ya Modbus RTU na Modbus TCP.
5. Irembo rya IoT mu nganda: Ibi bikoresho ntibishyigikira gusa guhindura protocole, ahubwo binatanga izindi nshingano za IoT, nko gukusanya amakuru, gukoresha interineti no guhuza cloud. Igisubizo gishingiye ku rubuga rwo gucunga kode nkeya ruvugwa muri iki gitabo gishobora koroshya inzira yo guteza imbere, kugabanya ikiguzi, no kunoza imikorere myiza y'iterambere.
Imbonerahamwe y'itumanaho
Kugira ngo ugere ku itumanaho rya Modbus RTU unyuze kuri ports za Ethernet, ubusanzwe hakenewe converter ya serial kuri Ethernet.
Muri iyi shusho, igikoresho gihujwe na converter binyuze kuri interface ya RS-485. Converter ihindura paki za protocole za Modbus RTU muri format ya Modbus TCP / IP hanyuma ikazohereza kuri network binyuze kuri Ethernet. Nyuma yo kwakira amakuru, igikoresho cyakira kigakora ibikorwa cyangwa ibisubizo bihuye.
Inyongera
Modbus RTU ifite ibyiza byinshi byo kohereza ubutumwa bwa kure, harimo ku giciro gito, gukoresha neza kohereza ubutumwa, ndetse no kurwanya ingaruka mbi. Mu gihe kizaza, hamwe n'iterambere rihoraho ry'ikoranabuhanga nka interineti y'ibintu na kode nto, guhuza imiyoboro ya Modbus RTU na Ethernet bizakoreshwa cyane, bitanga inkunga ikomeye ku buryo bwo gukora ikoranabuhanga mu nganda no mu buhanga.
Mu gihe kizaza, hazabaho ibikoresho byinshi bya IoT, kandi kohereza amakuru bizaba ikibazo cy'ingenzi kuri porogaramu za IoT. Mu guhuza Modbus RTU na ports za Ethernet, kohereza amakuru ku bikoresho bitandukanye bya IoT bishobora kugerwaho, bigahura n'ibikenewe mu kohereza amakuru mu bihe bitandukanye. Hagati aho, hamwe n'iterambere rya kode nto n'izindi koranabuhanga, kohereza amakuru bizoroha, byihuse kandi binoze. Kubwibyo, guhuza ports za Modbus RTU na Ethernet bizagira uruhare runini muri porogaramu za IoT mu gihe kizaza kandi bigire amahirwe menshi yo gukoresha porogaramu.
