Ambientika RS485 Programming Sud mphepo
Wiring
Pamakhazikitsidwe olumikiza mayunitsi angapo opumira mpweya, kulumikizana kwa serial kumachitika kudzera pa mawonekedwe a RS485. Kulumikizana kumachitika kudzera pa mizere yosiyana A, B ndi mzere wamba wapadziko lapansi (GND). Mayunitsi amalumikizana wina ndi mzake mu topology ya basi. Ndikofunikira kulumikiza chopinga chomaliza cha 120 ohms pakati pa mzere A ndi mzere B pagawo lomaliza la basi, kuti mutsimikizire mtundu wa chizindikiro.
Pokwerera 3: B
Pokwerera 4: A
Malo 5: GND
Kuphatikiza pa mawaya olondola a mizere ya RS485, gawo la mawonekedwe a wopanga amafunikira kuti agwirizane ndi machitidwe osiyanasiyana odzipangira okha: pamakina a KNX, RS485 yowonjezera (mwachitsanzo ngati KNX-TP/RS485 pachipata) ilipo, yomwe imasintha magawo ndi ma protocol pakati pa basi ya KNX ndi zida za RS485. M'machitidwe a Loxone, chowonjezera chovomerezeka cha Loxone RS485 chimagwiritsidwa ntchito m'malo mwake, chomwe chimaphatikizidwa molunjika ku malo a Loxone Miniserver.
Posankha mawonekedwe oyenerera, ndikofunikira kwambiri kuwonetsetsa kuti sichipata cha Modbus RS485, koma chipata chowonekera, chosalekeza cha RS485. Südwind amagwiritsa ntchito ma protocol omwe sagwirizana ndi muyezo wa Modbus.
Zokonda zosintha za DIP
Pamene kuwongolera kwapakati kumachitika kudzera pa KNX kapena Loxone, dongosololi limatenga ntchito zonse zapakhoma. Chigawo chachikulu chimapangidwa ngati mbuye wokhala ndi khoma.
Magawo ena onse mudongosolo amayikidwa ngati akapolo kudzera pa ma switch a DIP. Kutengera kugwiritsa ntchito, mwachitsanzoample monga makina operekera ndi kutulutsa mpweya, mayunitsi a akapolo amatha kuyendetsedwa molumikizana kapena mosagwirizana.
Master mit Fernbedienung = Mphunzitsi wokhala ndi chiwongolero chakutali
Master mit Wandpanel = Mphunzitsi wokhala ndi khoma
Kapolo gegenläufig Master = Kapolo - Mbuye amagwira ntchito mosasinthasintha
Kapolo gleichläufig Master = Kapolo -Master amagwira ntchito mogwirizana
Parametrization
Zigawo zoyankhulirana za seri kuti zikhazikitsidwe pakukulitsa kwa RS485:
- mlingo wa baud 9600 [bit/s]
- 8 magawo a data
- 1 ayime pang'ono
- palibe kufanana
Mauthenga amatumizidwa kuchokera ku control chapakati kupita ku mayunitsi onse olumikizidwa pakadutsa 500 ms.
Mauthengawa amakhala ndi mndandanda wa ma byte mu manambala a hexadecimal (ma nambala a hex). Chilichonse, monga \x02 kapena \x30, chimayimira baiti imodzi mumtundu wa hexadecimal.
Kufunsira kwa Status
Kufunsira kwa udindo kumatumizidwa kuchokera ku control central ndikuwunikidwa ndi Master unit. Potumiza funsoli, woyang'anira wapakati amasiya kutumiza mauthenga kwa masekondi atatu, kuti atsimikizire kuti mzerewo ulipo.
| Mkhalidwe | Lamulo |
| Kufunsira kwa Status | \x02\x30\x32\x30\x32\x03 |
Ngati palibe sensa yogwira ntchito kapena mawonekedwe, Master unit imayankha ndi uthenga wautali wa ma byte 11 mumtundu wotsatirawu wa hexadecimal: \x02\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x03.
Bite yoyamba \x02 imayika chiyambi cha uthenga (chithunzi choyambirira) ndikutsatiridwa ndi ma byte awiri \x30\x30 oimira "uthenga wamtundu" (\x30 umafanana ndi "0" mu zilembo za ASCII).
Ma 8 ma byte otsatirawa akuyimira ma regista amodzi okha. Iliyonse mwa ma bytewa imagwirizana ndi uthenga winawake. Ma registry anayi okha ndi omwe amagwiritsidwa ntchito: Regista yoyamba imayimira sensor ya madzulo, yachiwiri ndi yachitatu ya alamu yosinthira fyuluta ndi yachinayi ya alamu ya chinyezi. Bite yolandiridwa \x30 imagwirizana ndi "0" mu code ya ASCII. Izi zikutanthauza kuti sensor yoyenera kapena mawonekedwe sagwira ntchito. \X31 ikufanana ndi "1" ndipo ikuwonetsa momwe ntchito ikuyendera.
Uthenga umatha ndi byte \x03 yomwe ili yoyimitsa (mapeto a chimango) ndikuyika mapeto a kutumiza.
Alamu yosinthira fyuluta ikhoza kukhazikitsidwanso ndi lamulo.
Mauthenga
M'ndime yotsatirayi malamulo amodzi ndi ntchito zawo zoyenera akufotokozedwa. Monga tafotokozera pamwambapa, malamulowa ayenera kutumizidwa kuchokera kuchigawo chapakati chapakati kupita kumagulu onse okhudzana ndi nthawi ya 500 ms.
| Mode | Lamulo |
| Moto wozimitsa, gulu latsekedwa | \x02\x30\x31\x30\x30\x30\x30\x30\x31\x03 |
| Galimoto ikupuma, gulu lotseguka | \x02\x30\x31\x32\x30\x30\x30\x32\x31\x03 |

Mayendedwe a kasinthasintha - mwachitsanzoample pamene mukusintha kuchoka ku kudya kupita ku m'zigawo - zikhoza kusinthidwa pokhapokha ngati galimoto yazimitsidwa kale. Ngati galimoto yayatsidwa, lamulo la "motor pause" liyenera kuchitidwa kuti mupewe kuwonongeka kwa magetsi.
Pamanja mode: Kapolo amayika njira yozungulira kudzera pa DIP-switches malinga ndi kasinthidwe kokonzedweratu.

Malangizo a pulogalamu
Chigawochi chiyenera kusintha kasinthasintha pakapita nthawi, kuti apeze kutentha kwabwino kwambiri: masekondi 60 atenge ndikutsatiridwa ndi 10 masekondi.
Ndiye 60 masekondi m'zigawo kenako masekondi ena 10 kaye. Kuzungulira uku kumatsimikizira kusinthana kwabwino kwa mpweya komanso kubwezeretsa kutentha. Madzulo, sensa yophatikizika ya twilight imalola kuti isinthe zokha kukhala mawonekedwe ausiku.
Kusaka zolakwika
Ngati palibe kulumikizana kwakhazikitsidwa, kusintha kwa tchanelo A ndi kanjira B (mizere ya A/B pa RS485) kungathandize. Komanso, onetsetsani kuti choletsa choyimitsa chakhazikitsidwa bwino, makamaka pa siteshoni yomaliza m'basi, kuti mupewe zowunikira komanso kusokoneza kulumikizana.
