Ngemva kokuba ushintsho lube yimpumelelo, idivayisi izobuyisela ulwazi: 02 06 00 66 00 02 E8 27, ifomethi yayo idluliswa njengoba kukhonjisiwe kuthebula elilandelayo:

I-ID yedivayisi I-id yomsebenzi Qala Ikheli Indawo oya kuyo CRC16

01 06 00 66 00 02 e8 27

Impendulo kufanele ibe kudatha, ngemva kokuba ukuguqulwa kuphumelele, i-byte yokuqala ikheli ledivayisi entsha. Ngemuva kokuthi ikheli ledivayisi elijwayelekile lishintshiwe, lizoqala ukusebenza ngokushesha. Ngalesi sikhathi, umsebenzisi udinga ukushintsha umyalo wombuzo wesofthiwe ngesikhathi esifanayo.

Funda futhi Ulungise I-Baud Rate
(1). Funda isilinganiso se-baud
Izinga le-baud yasembonini elizenzakalelayo locingo ngu-9600. Uma udinga ukulishintsha, ungalishintsha ngokuya ngethebula elilandelayo kanye nephrothokholi yokuxhumana ehambisanayo. Okwesiboneloample, funda i-ID yezinga le-baud yedivayisi yamanje, umyalo uthi:01 03 00 67 00 01 35 D5, futhi ifomethi yayo icutshungulwa ngendlela elandelayo.

Shintsha izinga le-baud lisuka ku-9600 liye ku-38400, shintsha ikhodi isuka ku-3 iye ku-5. Izinga le-baud elisha lizoqala ukusebenza ngokushesha, lapho idivayisi izolahlekelwa impendulo yayo futhi izinga le-baud ledivayisi kufanele libuzwe ngokufanele. Kulungisiwe.

Funda Inani Lokulungisa
(1). Funda Inani Lokulungisa
Uma kunephutha phakathi kwedatha nezinga lereferensi, singehlisa iphutha lesibonisi ngokulungisa inani lokulungisa. Umehluko wokulungisa ungashintshwa ube uhlanganisa noma ukhiphe u-1000, okungukuthi, ububanzi bevelu bungu-0-1000 noma 64535 -65535. Okwesiboneloample, lapho inani lokubonisa lilincane kakhulu, singalilungisa ngokungeza i-100. Umyalo uthi: 01 03 00 6B 00 01 F5 D6 . Emyalweni othi 100 uthi i-hex 0x64 Uma udinga ukunciphisa, ungasetha inani elingafanele, njengokuthi -100, elihambisana nenani le-hexadecimal lika-FF 9C, elibalwa njenge-100-65535=65435, bese liguqulelwa ku-hexadecimal ukuze 0x FF 9C. Inani lokulungisa liqala ku-00 6B. Sithatha ipharamitha yokuqala njenge-example. Inani lokulungisa liyafundwa futhi lilungiswe ngendlela efanayo kumapharamitha amaningi.

I-ID yedivayisi	I-id yomsebenzi	Qala Ikheli	Ubude beDatha	CRC16
01	03	00 6b	00 01	F5 D6

Ukuze uthole umyalo olungile wombuzo, idivayisi izophendula, isiboneloample, idatha yempendulo ithi 01 03 0200 64 B9 AF, ifomethi yayo eboniswe kuthebula elilandelayo:

I-ID yedivayisi	I-id yomsebenzi	Ubude beDatha	Inani ledatha	CRC16
01	03	02	00 64	B9 AF

Kudatha yempendulo, i-byte yokuqala engu-01 ibonisa ikheli langempela ledivayisi yamanje, futhi i-00 6B iyirejista yenani lokulungiswa kwenani lokuqala lesifundazwe. Uma idivayisi inamapharamitha amaningi, amanye amapharamitha asebenza ngale ndlela. Okufanayo, izinga lokushisa elijwayelekile, kanye nomswakama kunale pharamitha, ukukhanya ngokuvamile akunayo le nto.
(2). Shintsha inani lokulungisa
Okwesiboneloample, uma inani lamanje lesimo lilincane kakhulu, sifuna ukwengeza u-1 kunani layo langempela, futhi inani lamanje kanye nomyalo wokusebenza wokulungisa ongu-100 uthi:01 06 00 6B 00 64 F9 FD.
