Modbus Communication: Gin ma pire tek me dongo yub me tic maber
Neno matut
Modbus obedo gin ma pol kare ki tiyo kwede i tic me yubu jami, ma ki yubu i mwaka 1979 me konyo lok i kin jami ma tiiyo piire kene. Modbus onwongo ki cako tic kwede ma calo gin ma ki tiyo kwede me cwalo ngec ki i dul ma ki lwongo ni serial layer, ki dong dong ki twero medo ne me tic kwede ki i serial, TCP/IP, ki User Datagram Protocol (UDP). Coc man miyo gonyo lok matut i kom kit ma ki keto kwede i tic.
Modbus protocol obedo ngo?
Modbus obedo yoo me gamo lapeny ma ki keto i tic kun wok ki i kin ladit ki opii. I kin ladit ki opii, lok kare weny time i kin aryo aryo (gin moni myero oyab peny ki lacen okuru lagam), ki gin ma tye ka penyo (ladit) en aye tye ki twero me cako lok acel acel. Pol kare, gin ma pire tek ni obedo gin ma dano ki jami ma tiyo kwede (HMI) onyo jami ma ki tiyo kwede me neno ki nongo ngec (SCADA), kun gin ma ki tiyo kwede me aryo ni obedo jami ma winyo, jami ma ki twero tic kwede (plcs), onyo jami ma ki lwongo ni programmable automation controllers (PACs). Gin ma tye i peny magi ki lagam magi, kacel ki dul ma cwalo kwena magi, ki nyutu ki dul ma pat pat me protocol.
Jami mene ma gicwako yub me Modbus?
Cik me Modbus ni ki miiyo kony bot jami mapol, medo ki jami ma ki lwongo ni programmable logic controllers (PLCs), jami ma ki lwongo ni remote terminal units (RTUs), sensors, actuators, human-machine interfaces (HMIs), ki jami mukene mapol ma tye i industrial automation ki industrial fields. Dul ma doro tic. Modbus kitiyo kwede i kabedo mapol ki dong odoko gin ma ki ngeyo pi tic kacel i kin jami ma ki yubu ki luyub jami mapol i dul ma calo yubu jami, teko, tero jami, ki tic me gedo.
Modbus gateway obedo gin ma loko kit me lok ma ki tiyo kwede i kin jami ma ki tiyo kwede i gang tic. En loko ki jami ma ryek, kwanyo ngec ki i jami ma rwom ne lapiny ki cwalo ne bot Modbus gateway, keto rwate ki komputa ma malo, ki timo Modbus protocol ki komputa ma tye i rwom ma malo.
Kit me lok ki Modbus
Cik me Modbus tye ki yoo adek me lok:
lRTU (Remote Terminal Unit)
lASCII (American Standard Code for Information Interchange)
lTCP/IP (Transmission Control Protocol/Internet Protocol)
I yub me Modbus, Modbus TCP ki Modbus RTU gubedo yoo me lok ma pol loyo. Kadi bed ni ki yubu gi me konyo poko ngec i kin jami tic, tye apokapoka mogo ma pire tek i kit me tic kwede ki kit me tic kwede.
Yo me lok ki rwom me lok
Modbus TCP tiyo ki TCP/IP protocol stack me cwalo ngec i kin dano, kun jenge i kom jami ma kwako network calo Ethernet me kelo cwalo ngec oyotoyot ki madwong.
Modbus RTU, i kom cing mukene, cwalo ngec ki i dul ma calo RS-485 ki RS-232, ma tye ki rwom me cwalo ngec ma lapiny. Cwalo ngec ki kit me tic kwede.
Modbus RTU keto jami ma ki coyo i dul ma ki lwongo ni compact binary format, medo ki kabedo me address, namba me tic, ngec, ki kabedo me checksum. Kit man ki cwalo maber i kit me binary, ma miyo bedo maber pi tic me kare ki kare onyo kabedo, tutwale i kabedo ma pe ki yub me network, ma calo kabedo me tic ma tiyo kene, jami ma ki keto i tic, network me sensor, ki jami ma ki tiyo kwede ma nok.
Modbus TCP, i kom cing mukene, loko byte acel acel me binary data me doko gin ma tye ki namba aryo ma ki keto, ma ki keto kacel ki cwalo i kit me TCP code. Pi kit ma yot kwede, genne, ki wel ne ma lamal, ki tiyo kwede i jami ma tiyo kene, ka gwoko ngec, gedo ma tiyo kene, ki Intanet me jami, ma mito lok mabor ki kare ma lamal ki ma mite pi cwalo ngec.
Akabedo me tic
I tic me yubu jami, Modbus ki tiyo kwede me kubu jami ma pat pat me yubu jami ki kelo neno ki doro kit ma jami tye ka wot kwede i kare ma opore; I lok ma mako teko, ki tiyo kwede me tic ki jami ma miyo teko, medo ki yubu teko, cwalo, ki poko ne; I lok ma mako tero dano, Modbus ki tiyo kwede me miyo lanyut me wot pa gadigadi i boma, neno kit ma motoka tye kwede, ki mukene; I lok ma mako tic pa gedo, Modbus ki tiyo kwede i HVAC, mac, ki jami ma gwoko kuc i gedo.
Ki dongo pa jami ma ki tiyo kwede i intanet ki jami ma ki tiyo kwede i intanet, Modbus bene tye ka kelo alokaloka ki medo rom pa jami ma pat pat ma tye ka loko. Me labolle, Modbus/TCP tye ka doko gin ma pire tek pi lok me Ethernet, ki jami ma ki tiyo kwede ma jenge i kom Modbus miyo kare bot jami macon me Modbus me kubu ki jami me kare ni, ma miyo twero me gwoko ki nyamo ngec i cloud.
I agiki ne, Modbus, ma calo gin ma dongo ki ma dano mapol tiyo kwede me lok i kin dano, oneno dongo pa diro me tic ki jami ma tiyo kene ki oketo guti maber pi ryeko me tic i anyim. Ki dongo pa jami ma ki tiyo kwede i kare ni, Modbus obi medde ki tic ma pire tek me kelo alokaloka ki alokaloka i dul ma kwako tic ki jami ma ki yubukeje.
