4.2Tlhaloso ea sebopeho sa data frame
Adopt Modbus-RTU protocol ea puisano, sebopeho se tjena:
Sebopeho sa pele ≥4 li-byte tsa nako
Khoutu ea aterese = 1 baiti
Khoutu ea tšebetso = 1 byte
Sebaka sa data = N li-byte
Ho hlahloba phoso = 16-bit CRC khoutu
Nako ea ho felisa sebopeho ≥ 4 byte
Khoutu ea aterese: aterese ea ho qala ea transmitter, e ikhethileng marang-rang a puisano (fektheri ea kamehla 0x01).
Khoutu ea ts'ebetso: taelo ea ts'ebetso ea taelo e fanoeng ke moamoheli, sesebelisoa sena se sebelisa khoutu ea ts'ebetso 0x03 feela (ho bala data ea ngoliso).
Sebaka sa data: Sebaka sa data ke lintlha tse khethehileng tsa puisano, ela hloko lintlha tse phahameng tsa 16bits pele!
Khoutu ea CRC: khoutu ea tlhahlobo ea li-byte tse peli.
Sebopeho sa foreimi ea potso e amohelang:
| Khoutu ea aterese | Khoutu ea tšebetso | Ngolisa aterese ea ho qala | Ngolisa bolelele | Sheba khoutu e tlase hanyane | Cheke khoutu e phahameng |

4.4Mohlala oa protocol ea puisano le tlhaloso
4.4.1 Botsa ka mocheso oa thepa le mongobo
Mohlala, botsa ka boleng ba mocheso le mongobo: aterese ea sesebelisoa ke 03
| Khoutu ea aterese | Khoutu ea tšebetso | Aterese ea pele | Bolelele ba data | Sheba khoutu e tlase hanyane | Cheke khoutu e phahameng |
| 0x03 | 0x03 | 0x01 0xF4 | 0x00 0x02 | 0x85 | 0xE7 |
Foreimi ea karabelo (mohlala, mocheso ke -10.1℃ le mongobo ke 65.8%RH)
| Khoutu ea aterese | Khoutu ea tšebetso | Nomoro ea li-byte tse sebetsang | Boleng ba mongobo | Boleng ba mocheso | Sheba khoutu e tlase hanyane | Cheke khoutu e phahameng |
| 0x03 | 0x03 | 0x04 | 0x02 0x92 | 0xFF 0x9B | 0x79 | 0xFD |
Mocheso: kenya ka mokhoa oa khoutu e tlatselletsang ha mocheso o le tlase ho 0 ℃
0xFF9B (Hexadecimal)= -101 => Mocheso = -10.1℃
Mongobo:
