DESCRIPTION

I-MODBUS ASCII/RTU iyiphrothokholi yokuxhumana yesigqila, ekwazi ukusekela izigqila ezingafika ku-247 ezixhunywe ebhasini noma kunethiwekhi yenkanyezi. Iphrothokholi isebenzisa uxhumano olulula emugqeni owodwa. Ngale ndlela, imiyalezo yokuxhumana ihamba emugqeni owodwa ezinhlangothini ezimbili eziphambene.
I-MODBUS TCP iyinhlobonhlobo yomndeni we-MODBUS. Ngokukhethekile, ihlanganisa ukusetshenziswa kwemiyalezo ye-MODUS endaweni “ye-inthanethi” noma “ye-inthanethi” kusetshenziswa iphrothokholi ye-TCP/IP kumbobo engaguquki engu-502.
Imilayezo ye-master-slave ingaba:

Ukufunda (Amakhodi omsebenzi $01, $03, $04): ukuxhumana kuphakathi kwenkosi nesigqila esisodwa. Ivumela ukufunda ulwazi mayelana nekhawunta ebuziwe

Ukubhala (Ikhodi yomsebenzi $10): ukuxhumana kuphakathi kwenkosi nesigqila esisodwa. Ivumela ukushintsha izilungiselelo zokubala
Ukusakaza (akutholakali ku-MODUS TCP): ukuxhumana kuphakathi kwenkosi nazo zonke izigqila ezixhunyiwe. Kuhlala kuwumyalo wokubhala (Ikhodi yomsebenzi $10) futhi idinga inombolo enengqondo engu-$00

Kuxhumo lohlobo lwamaphuzu amaningi (MODBUS ASCII/RTU), ikheli lesigqila (elibizwa nangokuthi inombolo enengqondo) livumela ukuhlonzwa kwekhawunta ngayinye ngesikhathi sokuxhumana. Ikhawunta ngayinye isethwe kusengaphambili inekheli lesigqila elizenzakalelayo (01) futhi umsebenzisi angalishintsha.
Esimeni se-MODBUS TCP, ikheli lesigqila lithathelwa indawo yibhayithi eyodwa, isihlonzi seyunithi.

Isizukulwane se-LRC

Inkambu ye-Longitudinal Redundancy Check (LRC) iyibhayithi eyodwa, equkethe inani kanambambili elingu-8–bit. Inani le-LRC libalwa idivayisi yokudlulisa, enezela i-LRC emyalezweni. Idivayisi eyamukelayo iphinda ibala i-LRC phakathi nokuthola umlayezo futhi iqhathanise inani elibaliwe nenani langempela elitholwe kunkambu ye-LRC. Uma amanani amabili engalingani, kuba nephutha. I-LRC ibalwa ngokuhlanganisa ndawonye amabhayithi angu-8–bit alandelanayo emlayezweni, ilahle noma yiziphi izithwala, bese okubili kugcwalise umphumela. I-LRC iyinkambu engu-8-bit, ngakho-ke ukungezwa okusha ngakunye kohlamvu okungaholela enanini elingaphezu kuka-255 zamadesimali kumane 'kugibele' inani lenkambu ku-zero. Ngenxa yokuthi ayikho ibhithi yesishiyagalolunye, into ephathwayo ilahlwa ngokuzenzakalelayo.
Inqubo yokukhiqiza i-LRC yile:

Engeza wonke amabhayithi kumlayezo, ungafaki 'ikholoni' nokuphetha CR LF. Bangeze enkambini engu-8-bit, ukuze okuthwalayo kuzolahlwa.

Susa inani lokugcina lenkambu ku-$FF, ukuze ukhiqize lezo–umphelelisi.
Engeza u-1 ukuze ukhiqize okubili-ukuphelelisa.

Ukubeka i-LRC Emlayezweni
Uma i-8-bit LRC (izinhlamvu ezi-2 ASCII) idluliselwa kumlayezo, uhlamvu olunezinga eliphezulu luzosakazwa kuqala, lulandelwe uhlamvu oluhlelekile. Okwesiboneloample, uma inani le-LRC lingu-$52 (0101 0010):

Isizukulwane se-CRC
Inkambu ye-Cyclical Redundancy Check (CRC) ingamabhayithi amabili, aqukethe inani elingu-16-bit. Inani le-CRC libalwa idivayisi yokudlulisela, ehlanganisa i-CRC emyalezweni. Idivayisi eyamukelayo iphinda ibala i-CRC phakathi nokuthola umlayezo futhi iqhathanise inani elibaliwe nenani langempela elitholwe kunkambu ye-CRC. Uma amanani amabili engalingani, kuba nephutha.
I-CRC iqalwa ngokulayisha kuqala irejista ye-16-bit kuwo wonke ama-1's. Bese kuqala inqubo yokusebenzisa amabhayithi angu-8-bit alandelanayo kokuqukethwe kwamanje kwerejista. Izingcezu eziyisishiyagalombili kuphela zedatha kuhlamvu ngalunye ezisetshenziselwa ukukhiqiza i-CRC. Izingcezu zokuqalisa nokumisa, futhi i-parity bit, ayisebenzi ku-CRC.
Ngesikhathi kukhiqizwa i-CRC, uhlamvu ngalunye lwe-8-bit lukhethekile ORed nokuqukethwe kwerejista. Khona-ke umphumela uyagudluzwa uqonde kokuncane kakhulu (LSB), ngoziro ogcwaliswe endaweni ebaluleke kakhulu (MSB). I-LSB iyakhishwa futhi ihlolwe. Uma i-LSB ibingu-1, irejista iba ikhethekile ORed enenani elimisiwe, elimisiwe. Uma i-LSB ibingu-0, akukho okukhethekile NOMA okwenzekayo.
Le nqubo iphindaphindiwe kuze kube yilapho kwenziwa amashifu ayisishiyagalombili. Ngemva koshintsho lokugcina (lwesishiyagalombili), uhlamvu olulandelayo lwe-8–bit lukhethekile ORed nenani lamanje lerejista, futhi inqubo iphinda amashifu ayisishiyagalombili ngaphezulu njengoba kuchazwe ngenhla. Okuqukethwe kokugcina kwerejista, ngemva kokuba zonke izinhlamvu zomlayezo sezisetshenzisiwe, inani le-CRC.
Inqubo ebaliwe yokukhiqiza i-CRC yile:

Layisha irejista engu-16-bit nge-$FFFF. Shayela lokhu ngerejista ye-CRC.
Okukhethekile NOMA ibhayithi yokuqala engu-8-bit yomlayezo enebhayithi ye-oda ephansi yerejista ye-CRC engu-16-bit, okubeka umphumela kurejista ye-CRC.
Shifta irejista ye-CRC kancane uye kwesokudla (uqonde ku-LSB), uziro–ugcwalisa i-MSB. Khipha futhi uhlole i-LSB.
(Uma i-LSB ibingu-0): Phinda Isinyathelo sesi-3 (olunye uhlangothi). (Uma i-LSB ibingu-1): Okukhethekile NOMA irejista ye-CRC enenani le-polynomial $A001 (1010 0000 0000 0001).
Phinda Izinyathelo 3 no-4 kuze kube amashifu angu-8 enziwe. Uma lokhu sekwenziwe, kuzobe sekucutshunguliwe i-8-bit byte ephelele.
Phinda Izinyathelo 2 ukuya ku-5 ukuthola i-8-bit byte elandelayo yomlayezo. Qhubeka wenze lokhu kuze kube yilapho wonke amabhayithi esecutshunguliwe.
Okuqukethwe kokugcina kwerejista ye-CRC yinani le-CRC.
Uma i-CRC ifakwa emyalezweni, amabhayithi ayo aphezulu naphansi kufanele ashintshwe njengoba kuchazwe ngezansi.

Ukubeka i-CRC Emlayezweni
Lapho i-16–bit CRC (amabhayithi angu-8–bit amabili) idluliselwa kumlayezo, i-byte ye-oda eliphansi izodluliswa kuqala, ilandelwe yi-high-order byte.
Okwesiboneloample, uma inani le-CRC lingu-$35F7 (0011 0101 1111 0111):
