4.2Qeexitaanka qaabka xogta
Qaado hab-maamuuska isgaarsiinta Modbus-RTU, qaabku waa sidatan:
Qaab dhismeedka hore ≥4 bytes waqtiga
Koodhka cinwaanka = 1 byte
Koodhka shaqada = 1 byte
Aagga xogta = N bytes
Hubinta qaladka = 16-bit CRC code
Waqtiga la dhammeynayo qaab-dhismeedka ≥ 4 bytes
Koodhka cinwaanka: ciwaanka bilawga ah ee gudbiyaha, kaas oo u gaar ah shabakada isgaarsiinta (warshada caadiga ah 0x01).
Koodhka shaqada: tilmaanta shaqada amarka ee uu soo saaray martigeliyaha, gudbiyahaan kaliya wuxuu isticmaalaa koodka shaqada 0x03 (akhri xogta diiwaanka).
Aagga xogta: Aagga xogtu waa xogta isgaarsiineed ee gaarka ah, u fiirso byte-ga sarreeya ee xogta 16bits marka hore!
CRC code: kood laba-byte ah.
Qaab dhismeedka su'aalaha martida loo yahay:
Koodhka cinwaanka | Koodhka shaqada | Diiwaangeli ciwaanka bilowga | Dhererka diiwaan gelinta | Hubi koodka waxoogaa yar | Koodhka jeegaga sare |
1 byte | 1 byte | 2 bytes | 2 bytes | 1 byte | 1 byte |
Qaab dhismeedka jawaabta addoonsiga:
Koodhka cinwaanka | Koodhka shaqada | Tirada bytes ansax ah | Aagga xogta | Aagga xogta labaad | Aagga xogta Nth | Hubi koodka |

4.4Tusaalaha borotokoolka isgaarsiinta iyo sharraxaadda
4.4.1 Wax ka weydii heerkulka qalabka iyo qoyaanka
Tusaale ahaan, weydii heerkulka iyo qiimaha qoyaanka: cinwaanka qalabku waa 03
Koodhka cinwaanka | Koodhka shaqada | Cinwaanka hore | Dhererka xogta | Hubi koodka waxoogaa yar | Koodhka jeegaga sare |
0x03 | 0x03 | 0x01 0xF4 | 0x00 0x02 | 0x85 | 0xE7 |
Qaabka jawaabta (tusaale ahaan, heerkulku waa -10.1℃ iyo qoyaanku waa 65.8% RH)
Koodhka cinwaanka | Koodhka shaqada | Tirada bytes ansax ah | Qiimaha qoyaanka | Qiimaha heerkulka | Hubi koodka waxoogaa yar | Koodhka jeegaga sare |
0x03 | 0x03 | 0x04 | 0x02 0x92 | 0xFF 0x9B | 0x79 | 0xFD |
Heerkulka: U soo rar qaabka koodka dhammaystirka marka heerkulku ka hooseeyo 0℃
0xFF9B (Hexadecimal)= -101 => Heerkul = -10.1℃
Qoyaanka
0x0292(Hexadecimal)=658=> Qoyaanka = 65.8%RH
Qalabku kuma xidhi karo PLC ama kombayutarka
Sababta macquulka ah:
1) Kumbuyuutarku wuxuu leeyahay dhowr dekedood oo COM ah, dekedda la doortayna waa khalad.
2) Ciwaanka qalabku waa khaldan yahay, ama waxaa jira aalado leh ciwaanno nuqul ah (warshadu waa dhammaan 1)
3) Heerka baud, habka hubinta, xogta bit, iyo xoogaa joogsiga waa khalad.
4) Muddada codbixinta ee martida loo yahay iyo wakhtiga jawaabta sugitaanka ayaa aad u gaaban, waxayna labaduba u baahan yihiin in laga dhigo in ka badan 200ms.
5) Wadarta guud ee 485 ayaa go'an, ama fiilooyinka A iyo B waxay ku xiran yihiin si kale.
6) Haddii tirada qalabku aad u badan tahay ama fiilooyinku aad u dheer yihiin, korontadu waa inay u dhowdahay, ku dar 485 xoojin ah, oo ku dar 120Ω iska caabin terminal isku mar.
7) USB ilaa 485 darawalka lama rakibin mana dhaawacmin.
8) Burburka qalabka.
