3. Modbus Protocol
Kayan Gwaji:COM serial kayan aiki
- Tsarin Sadarwa:
- Tsarin Saƙonni:Karanta Rijista, Buƙatar Frame
- Baiti: 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7
- Bayani: 0xD2 | 0x03 ku | Adireshin farawa | Yawan Masu Rajista (N) | Saukewa: CRC-16
- Misali: D203000C000157AA. D2 shine adireshin bawa, 03 shine umarnin karantawa, 000C shine adireshin farawa, 0001 yana nufin adadin rajistar da za a karanta shine 1, kuma 57AA shine CRC checksum.
- Daidaitaccen Tsarin Amsa:
- Baiti: 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8
- Bayani: 0xD2 | 0x03 ku | Tsawon Data | Darajar Rajista ta 1 | Darajar Nth Register | Saukewa: CRC-16
- L = 2* N
- Misali: N shine adadin rajista, D203020001FC56. D2 shine adireshin bawa, 03 shine umarnin karantawa, 02 shine tsayin bayanan da aka karanta, 0001 yana nufin ƙimar karatun 1st rajista, wanda shine matsayin fitarwa daga umarnin mai watsa shiri, kuma FC56 shine CRC checksum.
- Tsarin Saƙonni:Karanta Rijista, Buƙatar Frame
- Rubuta Rajista:Byte1 shine 0x06, inda 06 shine umarni don rubuta rajistar rikodi guda ɗaya, byte4-5 yana wakiltar umarnin mai watsa shiri.
- Daidaitaccen Tsarin Amsa:Madaidaicin firam ɗin amsawa don rubuta rijistar riƙo ɗaya yana bin tsari iri ɗaya da firam ɗin buƙata.
- Rubuta Rijistar Bayanai da yawa:Byte1 shine 0x10, inda 10 shine umarnin rubuta rajistar bayanai da yawa, byte2-3 shine farkon adireshin rajistar, byte4-5 yana wakiltar tsawon rajistar, kuma byte6-7 yana wakiltar abubuwan da ke cikin bayanan.
- Daidaitaccen Tsarin Amsa:Byte2-3 shine farkon adireshin rajista, byte4-5 yana wakiltar tsawon rijistar.
