INKCAZO

I-MODBUS ASCII/RTU yi-master-slave communication protocol, ekwazi ukuxhasa amakhoboka angama-247 aqhagamshelwe ebhasini okanye kwinethiwekhi yeenkwenkwezi. Iprotocol isebenzisa udibaniso olulula kumgca omnye. Ngale ndlela, imiyalezo yonxibelelwano ihamba kumgca omnye kumacala amabini achaseneyo.
I-MODBUS TCP luhlobo oluthile losapho lweMODBUS. Ngokukodwa, ibandakanya ukusetyenziswa kwemiyalezo ye-MODUS kwindawo "ye-Intranet" okanye "i-Intanethi" kusetyenziswa iprotocol ye-TCP/IP kwi-fixed port 502.
Imiyalezo ye-master-slave ingaba:

• Ukufunda (Iikhowudi zomsebenzi $ 01, $ 03, $ 04): unxibelelwano luphakathi kwenkosi kunye nekhoboka elilodwa. Ivumela ukufunda ulwazi malunga nekhawunta ebuzwayo
• Ukubhala (Ikhowudi yomsebenzi i-$ 10): unxibelelwano luphakathi kwenkosi kunye nekhoboka elilodwa. Ivumela ukutshintsha izicwangciso zokubala
• Usasazo (alufumaneki kwi-MODBUS TCP): unxibelelwano luphakathi kwenkosi kunye nawo onke amakhoboka adibeneyo. Ihlala ingumyalelo wokubhala (ikhowudi yoMsebenzi i-$ 10) kwaye ifuna inombolo enengqiqo $ 00

Kunxibelelwano lwamanqaku amaninzi (MODBUS ASCII / RTU), idilesi yekhoboka (ebizwa ngokuba yinombolo enengqiqo) ivumela ukuchongwa kwekhawunta nganye ngexesha lonxibelelwano. Ikhawuntala nganye icwangciswe kwangaphambili ngedilesi yekhoboka engagqibekanga (01) kwaye umsebenzisi unokutshintsha.
Kwimeko ye-MODBUS TCP, idilesi yekhoboka ithatyathelwa indawo yibhayithi enye, iyunithi yokuchonga.

Isizukulwana seLRC

I-Longitudinal Redundancy Check (LRC) indawo yi-byte enye, equlathe i-8-bit yexabiso lokubini. Ixabiso le-LRC libalwa ngesixhobo sothumelo, esidibanisa i-LRC kumyalezo. Isixhobo esifumanayo siphinda sibale i-LRC ngexesha lokufumana umyalezo kwaye sithelekise ixabiso elibaliweyo kwelona xabiso lifunyenweyo kwindawo ye-LRC. Ukuba la maxabiso mabini akalingani, kuvela impazamo. I-LRC ibalwa ngokudibanisa iibhayithi ezi-8-bit ezilandelelanayo kumyalezo, ukulahla naziphi na ii-caries, kunye nezimbini ezihambelana nesiphumo. I-LRC yintsimi ye-8-bit, ngoko ke udibaniso olutsha ngalunye lombhalo oluya kukhokelela kwixabiso eliphezulu kuno-255 wedesimali ngokulula 'ukuqengqeleka' kwexabiso lomhlaba ngo-zero. Ngenxa yokuba akukho bit yesithoba, ukuthwala kulahlwa ngokuzenzekelayo.
Inkqubo yokwenza i-LRC yile:

1. Yongeza zonke ii-bytes kumyalezo, ngaphandle kokuqalisa 'ikholoni' kunye nokuphelisa i-CR LF. Yongeza kwibala le-8-bit, ukuze izinto ezithwalayo zilahlwe.
2. Thabatha ixabiso lentsimi lokugqibela kwi-$FF, ukuvelisa ezona-zokuncedisana.
3. Yongeza i-1 ukuvelisa ezimbini-ukuhambelana.

Ukubeka iLRC kuMyalezo
Xa i-8-bit LRC (ii-2 ASCII characters) ithunyelwa kumyalezo, i-high-order character iya kuthunyelwa kuqala, ilandelwe yi-low-order character. Umzekeloample, ukuba ixabiso LRC yi $52 (0101 0010):

Isizukulwana seCRC
I-Cyclical Redundancy Check (CRC) ibala zii-byte ezimbini, eziqulethe ixabiso le-16-bit. Ixabiso le-CRC libalwa ngesixhobo sothumelo, esidibanisa i-CRC kumyalezo. Isixhobo esifumanayo siphinda sibale i-CRC ngexesha lokufumana umyalezo kwaye sithelekise ixabiso elibaliweyo kwixabiso elililo elifunyenwe kwibala le-CRC. Ukuba la maxabiso mabini akalingani, kuvela impazamo.
I-CRC iqalwa ngokufaka kuqala irejista ye-16-bit kuzo zonke ezi-1. Emva koko inkqubo iqala ukusebenzisa i-8-bit bytes elandelelanayo yomyalezo kwimixholo yangoku yerejista. Kuphela ngamasuntswana asibhozo edatha kumlinganiswa ngamnye asetyenziselwa ukuvelisa i-CRC. Qalisa kwaye umise amasuntswana, kwaye i-parity bit, ayisebenzi kwi-CRC.
Ngexesha lokwenziwa kwe-CRC, umlinganiswa ngamnye we-8-bit ukhethekile ORed kunye nemixholo yerejista. Emva koko isiphumo sitshintshelwa kwicala leyona nto incinci (LSB), kunye ne-zero ezaliswe kwindawo ebaluleke kakhulu (MSB). I-LSB iyakhutshwa kwaye ihlolwe. Ukuba i-LSB ibingu-1, irejista ke ngoko ikhethekile ORed ngokusetwa kwangaphambili, ixabiso elimiselweyo. Ukuba i-LSB ibingu-0, akukho khethekileyo OKANYE yenzekayo.
Le nkqubo iphinda iphindwe de kube kuqhutywe iinguqu ezisibhozo. Emva kokutshintsha kokugqibela (kwesibhozo), umlinganiswa olandelayo we-8-bit ukhethekile ORed kunye nexabiso langoku lerejista, kwaye inkqubo iphinda iishifti ezisibhozo njengoko kuchaziwe ngasentla. Imixholo yokugqibela yerejista, emva kokuba zonke iimpawu zomyalezo zisetyenzisiwe, lixabiso le-CRC.
Inkqubo ebaliweyo yokuvelisa i-CRC yile:

1. Layisha irejista ye-16-bit kunye ne-$FFFF. Tsalela oku kwirejista ye-CRC.
2. Kukhethekile OKANYE i-8-bit byte yokuqala yomyalezo enebhayithi ye-low-order byte yerejista ye-CRC ye-16-bit, ibeka isiphumo kwirejista ye-CRC.
3. Shifta irejista ye-CRC ibenye ukuya ekunene (ukusingise kwi-LSB), zero-ugcwalisa i-MSB. Khupha kwaye ujonge i-LSB.
4. (Ukuba i-LSB yayingu-0): Phinda iNyathelo lesi-3 (enye ishifti). (Ukuba i-LSB yayi-1): I-Exclusive OKANYE irejista ye-CRC enexabiso lepolynomial $ A001 (1010 0000 0000 0001).
5. Phinda aManyathelo 3 kunye ne-4 kude kube yi-8 shifts yenziwe. Xa oku kugqityiwe, i-8-bit byte epheleleyo iya kube igqityiwe.
6. Phinda aManyathelo 2 ukuya kwisi-5 kwi-8-bit byte elandelayo yomyalezo. Qhubeka ukwenza oku de zonke ii-bytes ziqwalaselwe.
7. Umxholo wokugqibela werejista ye-CRC lixabiso le-CRC.
8. Xa i-CRC ifakwe kumyalezo, iibhayithi zayo eziphezulu nezisezantsi kufuneka itshintshwe njengoko kuchaziwe ngezantsi.

Ukubeka i-CRC kuMyalezo
Xa i-16-bit CRC (ezimbini ze-8-bit byte) ihanjiswa kumyalezo, i-byte ephantsi iya kuhanjiswa kuqala, ilandelwe yi-byte ephezulu.
Umzekeloample, ukuba ixabiso CRC $35F7 (0011 0101 1111 0111):

PHAWULA: iirejista ze-RTC ($2000…$2005) zifumaneka kuphela kwiimitha zamandla nge-Ethernet Firmware rel. 1.15 okanye ngaphezulu.
PHAWULA: ukuba umyalelo wokubhala we-RTC uqulethe amaxabiso angafanelekanga (umzekelo, i-30 kaFebruwari), ixabiso aliyi kwamkelwa kwaye isixhobo siphendula ngekhowudi eyahlukileyo (Ixabiso elingekho mthethweni).
PHAWULA: kwimeko yokulahleka kwe-RTC ngenxa yokucinywa kombane ixesha elide, setha kwakhona ixabiso le-RTC (usuku, inyanga, unyaka, iiyure, imiz, imizuzwana) ukuqalisa kwakhona ukurekhoda.
