Ikhowudi	8-bit yokubini
Incinci yedatha	8-bit
I-Parity bit	Akukho nanye
Yima kancinci	1-bit
Kujongwa impazamo	CRC (ikhowudi yebhayisikile engafunekiyo)

4.2Inkcazo yefomathi yesakhelo sedatha

Yamkela iprotocol yonxibelelwano ye-Modbus-RTU, ifomathi imi ngolu hlobo lulandelayo:

Isakhiwo sokuqala ≥4 bytes zexesha

Ikhowudi yedilesi = 1 byte

Ikhowudi yokusebenza = 1 byte

Indawo yedatha = iibhayithi eziN

Ukukhangela impazamo = ikhowudi ye-CRC ye-16-bit

Ixesha lokuphelisa isakhiwo ≥ 4 bytes

Ikhowudi yedilesi: idilesi yokuqala ye-transmitter, ekhethekileyo kwinethiwekhi yonxibelelwano (i-factory default 0x01).

Ikhowudi yomsebenzi: umyalelo womsebenzi womyalelo okhutshwe ngumninimzi, lo mthumeli usebenzisa kuphela ikhowudi yokusebenza 0x03 (funda idatha yerejista).

Indawo yedatha: Indawo yedatha yidatha ethile yonxibelelwano, nikela ingqalelo kwi-byte ephezulu yedatha ye-16bits kuqala!

Ikhowudi ye-CRC: ikhowudi yokujonga ezimbini-byte.

Ubume besakhelo sombuzo womamkeli:

Ikhowudi yedilesi	Ikhowudi yokusebenza	Bhalisa idilesi yokuqala	Bhalisa ubude	Jonga ikhowudi encinci	Ikhowudi yokutshekisha ephezulu
Ibhayithi e-1	Ibhayithi e-1	iibyte ezi-2	iibyte ezi-2	Ibhayithi e-1	Ibhayithi e-1

Ulwakhiwo lwesakhelo sempendulo yamakhoboka:

Ikhowudi yedilesi	Ikhowudi yokusebenza	Inani leebhayithi ezisebenzayo	Indawo yedatha	Indawo yesibini yedatha	Nth indawo yedatha	Jonga ikhowudi
Ibhayithi e-1	Ibhayithi e-1	Ibhayithi e-1	iibyte ezi-2	iibyte ezi-2	iibyte ezi-2	iibyte ezi-2

4.3Inkcazo yedilesi yerejista yonxibelelwano

Imixholo yerejista iboniswe kolu luhlu lulandelayo (inkxaso 03/04 ikhowudi yomsebenzi):

Bhalisa idilesi	PLC okanye idilesi yoqwalaselo	Umxholo	Ukusebenza
500	40501	Ixabiso lokufuma (amaxesha ali-10 elona xabiso)	Funda uqhubeleke
501	40502	Ixabiso lobushushu (amaxesha ali-10 elona xabiso)	Funda uqhubeleke
502	40503	Ixabiso lengxolo (amaxesha ali-10 elona xabiso)	Funda uqhubeleke
503	40504	PM2.5 (ixabiso lokwenyani)	Funda uqhubeleke
504	40505	PM10 (ixabiso lokwenyani)	Funda uqhubeleke
505	40506	Ixabiso loxinzelelo lwe-atmospheric (iyunithi ye-Kpa, ixabiso lokwenyani amaxesha ali-10)	Funda uqhubeleke
506	40507	Ixabiso eliphezulu le-16-bit lexabiso le-Lux le-20W (ixabiso lokwenyani)	Funda uqhubeleke
507	40508	Ixabiso eliphantsi le-16-bit lexabiso le-Lux lika-20W (ixabiso lokwenyani)	Funda uqhubeleke

4.4Umzekelo weprotocol yonxibelelwano kunye nengcaciso

4.4.1 Buza malunga nobushushu besixhobo kunye nokufuma

Umzekelo, buza malunga nexabiso lobushushu kunye nokufuma: idilesi yesixhobo ngu-03

Ikhowudi yedilesi	Ikhowudi yokusebenza	Idilesi yokuqala	Ubude bedatha	Jonga ikhowudi encinci	Ikhowudi yokutshekisha ephezulu
0x03	0x03	0x01 0xF4	0x00 0x02	0x85	0xE7

Isakhelo sokuphendula (umzekelo, iqondo lobushushu yi -10.1℃ kunye nokufuma yi-65.8%RH)

Ikhowudi yedilesi	Ikhowudi yokusebenza	Inani leebhayithi ezisebenzayo	Ixabiso lokufuma	Ixabiso lobushushu	Jonga ikhowudi encinci	Ikhowudi yokutshekisha ephezulu
0x03	0x03	0x04	0x02 0x92	0xFF 0x9B	0x79	0xFD

Ubushushu: layisha ngendlela yekhowudi yokuncedisana xa ubushushu bungaphantsi kwe-0℃

0xFF9B (Hexadecimal)= -101 => Ubushushu = -10.1℃

Ukufuma:

0x0292(Hexadecimal)=658=> Ukufuma = 65.8%RH

Iingxaki eziqhelekileyo kunye nezisombululo

Isixhobo asikwazi ukuqhagamshela kwi-PLC okanye kwikhompyutha

Isizathu esinokubakho:

1) Ikhompyuter inamazibuko e-COM amaninzi kwaye izibuko ezikhethiweyo azichanekanga.

2) Idilesi yesixhobo ayilunganga, okanye kukho izixhobo ezineedilesi eziphindwe kabini (ukusilela kwefektri konke oku-1)

3) Izinga le-baud, indlela yokukhangela, i-data bit, kunye ne-stop bit ayilunganga.

I-4) Ikhefu lokuvota lomkhosi kunye nexesha lokuphendula lokulinda lifutshane kakhulu, kwaye zombini kufuneka zibekwe ngaphezu kwe-200ms.

I-5) I-485 iyonke i-wire inqanyuliwe, okanye i-A kunye ne-B iingcingo zixhunyiwe ngasemva.

I-6) Ukuba inani lezixhobo likhulu kakhulu okanye i-wiring ide kakhulu, ukunikezelwa kwamandla kufuneka kube kufuphi, yongeza i-booster ye-485, kwaye ungeze i-120Ω i-terminal resistance ngexesha elifanayo.

7) I-USB ukuya kumqhubi we-485 ayifakwanga okanye yonakaliswe.

8) Umonakalo wezixhobo.
