Ingcaciso yeMveliso

Ulwazi ngempazamo yoNxibelelwano kunye nokuSebenza kweDatha:
Umgcini okanye ikhoboka unokusebenzisa ikhowudi yokutshekisha ukufumanisa ukuba ulwazi olufunyenweyo luchanekile. Ngenxa yengxolo ye-elektroniki okanye olunye uphazamiso, iimpazamo ngamanye amaxesha zenzeka ngexesha losulelo lolwazi. Ikhowudi yokutshekisha impazamo (i-CRC) inokujonga ukuba ngaba ulwazi lomgcini okanye ikhoboka ngexesha lenkqubo yothutho lwedatha ayichanekanga, kwaye i-datatone ephosakeleyo ingalahlwa okanye ifumane ukhuseleko kunye nokusebenza kakuhle kwe Inkqubo.
I-CRC (iKhowudi ye-cyclic eguqukayo) yomgaqo wonxibelelwano lweModbus iqulethe i-2 byte, eyinombolo ye-16-binary. Ikhowudi ye-CRC ibalwa sisixhobo sokuthumela (umgcini) kwaye sabekwa ekupheleni kwesakhelo solwazi esithunyelwe. Isixhobo (ikhoboka) elifumana ulwazi olufumana i-CRC yolwazi olufumeneyo kwaye lithelekisa ukuba ngaba i-CRC ibaliwe i-CRC efunyenweyo. Ukuba bobabini abahambelani, kwenzeke impazamo.
Kuphela zii-bits ezisi-8 zedatha ezisetyenzisiweyo xa kusenziwa ukubalwa kwe-CRC. Isiqalo esincinci, seka kancinci kunye ne-subty encinci ayibandakanyeki kubalo lwe-CRC.

Xa amanqanaba emiqolo afumanisa imposiso ngaphandle kwempazamo yeKhowudi yeCRC, kufuneka athumele ulwazi kwi-vers kwinginginya. Esona sikhundla siphezulu seKhowudi yeMisebenzi ngu-1, oko kukuthi, ikhowudi yokusebenza ebuyile kwikhoboka ukuya kwi-HOSIRS yikhowudi yomsebenzi ethunyelwe ngumamkeli we-128. Ezi khowudi zilandelayo zibonisa ukuba kwenzeke impazamo engalindelekanga.
Ukuba ulwazi olufunyenwe likhoboka elivela kwi-Matshi luqukethe iimpazamo zeCRC, iya kutyeshelwa likhoboka.
Ifomati yekhowudi yempazamo ebuyiselweyo likhoboka ngolu hlobo lulandelayo (ngaphandle kweKhowudi yeCRC):
Ikhowudi yedilesi: 1 byte
Ikhowudi yokuSebenza: I-1 Byte (eyona iphakamileyo i-1)
Ikhowudi yempazamo: 1 byte
Ikhowudi yeCRC: 2 Byte.

Umatshini wekhoboka uphendule kule khowudi yempazamo ilandelayo:
81. Ikhowudi yomsebenzi ongekho mthethweni.
Ikhowudi yomsebenzi eyamkelweyo ayixhaswa yitafile yamakhoboka.
82. Funda idilesi yedatha engekho mthethweni.
Indawo yedatha echaziweyo ingaphandle koluhlu lwedilesi yetafile.
I-83. Ixabiso ledatha elingekho mthethweni.

Ixabiso ledatha elithunyelwe yinkosi efunyenweyo lingaphezulu koluhlu lwedatha yesalathiso sekhoboka.

Iimveliso eziphambili zenkampani yethu zibandakanya iqhulo le-electromagnetic, ababandayo be-ultrasonic okanye idyokhwe yobushushu, inqwelo-moya evulekileyo, inqwelo-moya evulekileyo, i-elektromagnetic okanye iqhuma lobushushu.
