Izintambo
Ekufakeni okuxhuma amayunithi amaningi okungenisa umoya, ukuxhumana kwe-serial kwenzeka ngesixhumi esibonakalayo se-RS485. Ukuxhumana kwenzeka ngelayini yesiginali ehlukile A, B kanye nomugqa ojwayelekile womhlaba (GND). Amayunithi axhunywe kwelinye ku-topology yebhasi. Kuyisibopho ukuxhuma isinqamuli esinqamulayo esingu-120 ohms phakathi komugqa A nomugqa B kuyunithi yokugcina yomzimba yolayini webhasi, ukuze kuqinisekiswe ikhwalithi yesiginali.
Itheminali 3: B
Itheminali 4: A
Itheminali 5: GND
Ngaphezu kokufakwa kwezintambo ezifanele kwemigqa ye-RS485, imojula yesixhumi esibonakalayo eqondene nomkhiqizi iyadingeka ukuze kuhlanganiswe izinhlelo ezishintshayo ezihlukene: kumasistimu asekelwe ku-KNX, isandiso se-RS485 (isb njengesango le-KNX-TP/RS485) siyatholakala, esiguqula amazinga nezivumelwano phakathi kwebhasi le-KNX namadivayisi e-RS485. Ezinhlelweni ze-Loxone, isandiso esisemthethweni se-Loxone RS485 sisetshenziswa esikhundleni, esihlanganiswe ngqo endaweni ye-Loxone Miniserver.
Lapho ukhetha isixhumi esibonakalayo esifanele, kubaluleke kakhulu ukwenza isiqiniseko sokuthi akulona isango le-Modbus RS485, kodwa isango le-RS485 elibonisa ngale, eliwuchungechunge. I-Südwind isebenzisa izivumelwano zobunikazi ezingafani nezinga le-Modbus.
Izilungiselelo zokushintsha kwe-DIP
Njengoba ukulawula okumaphakathi kwenzeka nge-KNX noma nge-Loxone, isistimu ithatha ngokuphelele imisebenzi yephaneli yodonga. Iyunithi eyinhloko ilungiselelwe njengengcweti enephaneli yodonga.
Wonke amanye amayunithi ohlelweni asethwe njengezigqila ngokushintsha kwe-DIP. Kuye ngesicelo, isiboneloampnjenge-supply and exhaust air systems, amayunithi esigqila angasetshenziswa ngokuhambisana noma ngokulinganayo.
I-Master mit Fernbedienung = Inkosi enokulawula kude
I-Master mit Wandpanel = Ingcweti enephaneli yodonga
I-Slave gegenläufig Master = Isigqila - Inkosi isebenza ngokulinganayo
Isigqila se-gleichläufig Master = Isigqila -Inkosi isebenza ngokuvumelana
I-Parametrization
Amapharamitha wokuxhumana we-serial azolungiswa kusandiso se-RS485:
- isilinganiso se-baud 9600 [bit/s]
- 8 izingcezu zedatha
- 1 ima kancane
- akukho ukulingana
Imilayezo ithunyelwa kusukela kusilawuli esimaphakathi kuwo wonke amayunithi axhunyiwe ngezikhawu ezingu-500 ms.
Le milayezo iqukethe ukulandelana kwamabhayithi kunombolo ye-hexadecimal (izinombolo ze-hex). I-elementi ngayinye, njengokuthi \x02 noma \x30, imele ibhayithi eyodwa ngefomethi ye-hexadecimal.
Uphenyo ngesimo
Umbuzo wesimo uthunyelwa usuka kumlawuli omaphakathi futhi uhlolwe yiyunithi Eyinhloko. Ngenkathi uthumela lo mbuzo, isilawuli esimaphakathi siyayeka ukuthumela imilayezo imizuzwana emi-3, ukuze kuqinisekiswe ukuthi ulayini uyatholakala.
| Isimo | Umyalo |
| Uphenyo ngesimo | \x02\x30\x32\x30\x32\x03 |
Uma ingekho inzwa esebenzayo noma isimo, iyunithi Eyinhloko iphendula ngomlayezo omude wamabhayithi angu-11 kufomethi elandelayo ye-hexadecimal: \x02\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x03.
Ibhayithi yokuqala \x02 ibeka isiqalo somlayezo (uhlaka lokuqala) futhi ilandelwa amabhayithi amabili \x30\x30 amele "umlayezo wesimo" (\x30 ihambisana nokuthi "0" ezinhlamvu ze-ASCII).
Amabhayithi angu-8 alandelayo amelela amarejista esimo esisodwa. Ngayinye yalawa mabhayithi ihambisana nomlayezo othile. Kusetshenziswa amarejista amane okuqala kuphela: Irejista yokuqala imele inzwa yokuhlwa, eyesibili neyesithathu imele i-alamu yokushintsha isihlungi kanti eyesine imele i-alamu yomswakama. Ibhayithi etholiwe \x30 ihambisana nokuthi “0” kukhodi ye-ASCII. Lokho kusho, ukuthi inzwa efanele noma isimo asisebenzi. \X31 ihambisana nokuthi “1” futhi ikhombisa isimo esisebenzayo.
Umlayezo uphetha nge-byte \x03 okuyi-stop bit (uhlaka lokugcina) bese usetha isiphetho sokudlulisa.
I-alamu yokushintsha isihlungi ingasethwa kabusha ngomyalo.
Imilayezo
Esigabeni esilandelayo imiyalo eyodwa nemisebenzi yayo efanele ichaziwe. Njengoba kushiwo ngenhla, imiyalo idinga ukuthunyelwa kusuka kuyunithi yokulawula emaphakathi kuwo wonke amayunithi axhunyiwe ngesikhawu sama-500 ms.
| Imodi | Umyalo |
| Imoto ivaliwe, iphaneli ivaliwe | \x02\x30\x31\x30\x30\x30\x30\x30\x31\x03 |
| Injini imisiwe, iphaneli ivuliwe | \x02\x30\x31\x32\x30\x30\x30\x32\x31\x03 |
| Imotor icishiwe, setha kabusha ushintsho lwesihlungi | \x02\x30\x31\x30\x30\x30\x31\x30\x30\x03 |
Isiqondiso sokuzungezisa - ngokwesiboneloample lapho usuka ekuthatheni uye ekukhishweni - ingashintshwa kuphela uma injini ike yacishwa ngaphambili. Uma injini ivuliwe, umyalo othi "motor pause" kufanele usetshenziswe ukuze kugwenywe ukulimala kokunikezwa kwamandla.
Imodi yokwenziwa ngesandla: Isigqila sisetha isiqondiso sokuzungezisa ngamaswishi e-DIP ngokuya ngokucushwa okunqunywe kusengaphambili.

Amacebo ohlelo
Iyunithi kufanele iguqule indlela yokuzungezisa ngesikhathi esithile, ukuze ithole ukutholwa kokushisa okungcono kakhulu okungakhonakala: ukuthatha kwamasekhondi angu-60 okulandelwa ukuphunyuzwa kwamasekhondi angu-10.
Bese kukhishwa imizuzwana engu-60 kulandelwe amanye amasekhondi angu-10 ikhefu. Lo mjikelezo uqinisekisa ukushintshana komoya okusebenzayo kanye nokuthola ukushisa. Lapho kuhwalala inzwa ehlanganisiwe ye-twilight ivumela ukushintshela kumodi yasebusuku ngokuzenzakalelayo.
Ukuxazulula inkinga
Uma kungekho ukuxhumana okuhleliwe, ukushintshwa kwesiteshi A nesiteshi B (olayini be-A/B ku-RS485) kungasiza. Ngaphezu kwalokho, hlola ukuthi isiphikisa esinqamulayo sibekwe ngendlela efanele yini, ikakhulukazi esiteshini sokugcina ebhasini, ukuze ugweme ukubonakaliswa kwesignali nokuphazamiseka kokuxhumana.
