Yankho la ntchito
Kodi ntchito?
Communication Protocol
Chogulitsacho chimagwiritsa ntchito mtundu wa RS485 MODBUS-RTU wokhazikika, malamulo onse ogwiritsira ntchito kapena oyankha ndi data ya hexadecimal. Adilesi yokhazikika ya chipangizocho ndi 1 pamene chipangizocho chimatumizidwa, ndipo mlingo wokhazikika wa baud ndi 9600, 8, n, 1.
Werengani Data (ID ya ntchito 0x03)
Kufunsira chimango (hexadecimal), kutumiza example: Funso 1# chipangizo 1 deta, wolandira kompyuta amatumiza lamulo:01 03 00 00 00 01 84 0A.
| ID ya chipangizo | ID ya ntchito | Adilesi Yoyambira | Kutalika Kwadongosolo | CRC16 |
| 01 | 03 | 00 00 | 00 01 | 84 0a |
Pamafunso olondola, chipangizocho chidzayankha ndi data: 01 03 02 00 79 79 A6, yankho losankhidwa motere:
| ID ya chipangizo | ID ya ntchito | Kutalika Kwadongosolo | Data 1 | Check Kodi |
| 01 | 03 | 02 | 00 79 | 79 a6 |
Kufotokozera Kwa data: Zomwe zili mu lamulo ndi hexadecimal. Tengani data 1 ngati example. 00 79 imasinthidwa kukhala mtengo wa decimal wa 121. Ngati kukula kwa deta ndi 100, mtengo weniweni ndi 121/100 = 1.21.
Ena ndi zina zotero.

werengani ndikusintha adilesi ya chipangizocho
(1) Werengani kapena funsani adilesi ya chipangizocho
Ngati simukudziwa adiresi yamakono yamakono ndipo pali chipangizo chimodzi chokha pa basi, mungagwiritse ntchito lamulo FA 03 00 64 00 02 90 5F Funso chipangizo adiresi.
| ID ya chipangizo | ID ya ntchito | Adilesi Yoyambira | Kutalika Kwadongosolo | CRC16 |
| FA | 03 | 00 64 | 00 02 | 90 5F |
FA ndi 250 pa adilesi yonse. Mukapanda kudziwa adilesi, mutha kugwiritsa ntchito 250 kuti mupeze adilesi yeniyeni ya chipangizocho, 00 64 ndiye kaundula wachitsanzo cha chipangizocho.
Kuti mupeze lamulo lolondola, chipangizocho chidzayankha, mwachitsanzoample, deta yoyankha ndi: 01 03 02 07 12 3A 79, mawonekedwe ake akuwonetsedwa patebulo lotsatirali:
| ID ya chipangizo | ID ya ntchito | Adilesi Yoyambira | Model Kodi | CRC16 |
| 01 | 03 | 02 | 55 3C 00 01 | 3A 79 |
Yankho ayenera kukhala mu deta, baiti woyamba 01 limasonyeza kuti adiresi weniweni wa chipangizo panopa ndi, 55 3C kutembenuzidwa decimal 20182 limasonyeza kuti panopa chipangizo chitsanzo chachikulu ndi 21820, ndi ma byte awiri otsiriza 00 01 Zimasonyeza kuti chipangizo. ali ndi kuchuluka kwake.
(2)Sinthani adilesi ya chipangizocho
Za example, ngati adilesi yamakono ndi 1, tikufuna kuyisintha kukhala 02, lamulo ndi: 01 06 00 66 00 02 E8 14.
| ID ya chipangizo | ID ya ntchito | Adilesi Yoyambira | Kopita | CRC16 |
| 01 | 06 | 00 66 | 00 02 | E8 14 |
Kusinthako kukachitika bwino, chipangizocho chidzabweza zambiri: 02 06 00 66 00 0 2 E8 27, mawonekedwe ake amagawidwa monga momwe tawonetsera patebulo ili:
| ID ya chipangizo | ID ya ntchito | Adilesi Yoyambira | Kopita | CRC16 |
| 01 | 06 | 00 66 | 00 02 | E8 27 |
Yankho liyenera kukhala mu data, pambuyo pa kusinthidwa bwino, byte yoyamba ndi adiresi yatsopano ya chipangizo. Adilesi ya chipangizo ikasinthidwa, iyamba kugwira ntchito nthawi yomweyo. Panthawiyi, wosuta ayenera kusintha lamulo lafunso la pulogalamuyo nthawi yomweyo.
Werengani ndi Kusintha Baud Rate
(1) Werengani mlingo wa baud
Chipangizo chokhazikika cha fakitale ya baud ndi 9600. Ngati mukufuna kusintha, mukhoza kusintha malinga ndi tebulo ili ndi ndondomeko yolumikizirana. Za example, werengani chipangizo chamakono cha baud mlingo ID, lamulo ndi: 01 03 00 67 00 01 35 D5, mawonekedwe ake amagawidwa motere.
| ID ya chipangizo | ID ya ntchito | Kutalika Kwadongosolo | Mtengo ID | CRC16 |
| 01 | 06 | 02 | 00 03 | pa f8 |
zolembedwa molingana ndi kuchuluka kwa baud, 03 ndi 9600, mwachitsanzo, chipangizo chapano chili ndi chiwopsezo cha 9600.
(2)Sintha mlingo wa baud
Za example, kusintha mlingo wa baud kuchokera 9600 kuti 38400, mwachitsanzo kusintha kachidindo kuchokera 3 mpaka 5, lamulo ndi: 01 06 00 67 00 05 F8 1601 03 00 66 00 01 64 15 .
| ID ya chipangizo | ID ya ntchito | Adilesi Yoyambira | Target Baud Rate | CRC16 |
| 01 | 03 | 00 66 | 00 01 | 64 15 |
Sinthani mlingo wa baud kuchokera ku 9600 kupita ku 38400, kusintha kachidindo kuchokera ku 3 mpaka 5. Mlingo watsopano wa baud udzachitika nthawi yomweyo, pomwe chipangizocho chidzataya yankho lake ndipo mlingo wa baud wa chipangizocho uyenera kufunsidwa moyenerera. Zosinthidwa.
Werengani Mtengo Wowongolera
(1) Werengani Mtengo Wowongoleredwa
Pakakhala cholakwika pakati pa data ndi mulingo wolozera, titha kuchepetsa cholakwika chowonetsera posintha mtengo wowongolera. Kusiyana kowongolera kumatha kusinthidwa kukhala kuphatikiza kapena kuchotsera 1000, ndiye kuti, mtengo wamtengo wapatali ndi 0-1000 kapena 64535 -65535. Za example, pamene mtengo wowonetsera uli wochepa kwambiri, tikhoza kukonza mwa kuwonjezera 100. Lamulo ndi: 01 03 00 6B 00 01 F5 D6 . Mu lamulo la 100 ndi hex 0x64 Ngati mukufuna kuchepetsa, mukhoza kukhazikitsa mtengo woipa, monga -100, wolingana ndi mtengo wa hexadecimal wa FF 9C, womwe umawerengedwa ngati 100-65535 = 65435, ndikusinthidwa kukhala hexadecimal kuti 0x ndi 9C. Mtengo wowongolera umayambira pa 00 6B. Timatenga parameter yoyamba ngati example. Mtengo wowongolera umawerengedwa ndikusinthidwa mofanana ndi magawo angapo.
| ID ya chipangizo | ID ya ntchito | Adilesi Yoyambira | Kutalika Kwadongosolo | CRC16 |
| 01 | 03 | 00 6b ndi | 00 01 | F5 D6 |
Kuti mupeze lamulo lolondola, chipangizocho chidzayankha, mwachitsanzoample, data yoyankhira ndi: 01 03 02 00 64 B9 AF, mawonekedwe ake akuwonetsedwa patebulo lotsatirali:
| ID ya chipangizo | ID ya ntchito | Kutalika Kwadongosolo | Mtengo wa data | CRC16 |
| 01 | 03 | 02 | 00 64 | B9 AF |
Mu data yankho, byte yoyamba 01 imasonyeza adiresi yeniyeni ya chipangizo chamakono, ndipo 00 6B ndiye woyamba boma kuchuluka kuwongolera mtengo kaundula. Ngati chipangizocho chili ndi magawo angapo, magawo ena amagwira ntchito motere. Zomwezo, kutentha, ndi chinyezi zimakhala ndi chizindikiro ichi, kuwala nthawi zambiri kulibe chinthu ichi.
(2) Sinthani mtengo wowongolera
Za example, ngati kuchuluka kwa boma kuli kochepa kwambiri, tikufuna kuwonjezera 1 ku mtengo wake weniweni, ndipo mtengo wamakono kuphatikiza 100 kuwongolera opareshoni lamulo ndi: 01 06 00 6B 00 64 F9 FD.
| ID ya chipangizo | ID ya ntchito | Adilesi Yoyambira | Kopita | CRC16 |
| 01 | 06 | 00 6b ndi | 00 64 | F9 FD |
Pambuyo pochita bwino, chipangizocho chidzabwezera zambiri: 01 06 00 6B 00 64 F9 FD, magawowa amayamba kugwira ntchito mwamsanga pambuyo posintha bwino.
Za example, mndandanda ndi 0 ~ 30 ℃, kutulutsa kwa analogi ndi 4 ~ 20mA chizindikiro chamakono, kutentha, ndi zamakono Ubale wowerengera ukuwonetsedwa mu formula: C = (A2-A1) * (X-B1) / (B2 -B1) + A1, kumene A2 ndi kutentha kwapamwamba, A1 ndiye malire otsika, B2 ndi malire apamwamba, B1 ndi malire apansi, X ndi chiwerengero cha kutentha chomwe chimawerengedwa, ndipo C ndi chiwerengero chowerengedwa. mtengo wapano. Mndandanda wamakhalidwe omwe amagwiritsidwa ntchito kwambiri ndi awa:
