Wiring
Ing instalasi sing nyambungake sawetara unit ventilasi, komunikasi serial dumadi liwat antarmuka RS485. Sambungan kasebut dumadi liwat jalur sinyal diferensial A, B lan garis bumi umum (GND). Unit kasebut disambungake menyang siji liyane ing topologi bus. Iku prentah kanggo nyambungake resistor terminating 120 ohm antarane baris A lan baris B ing unit fisik pungkasan saka baris bis, kanggo njamin kualitas sinyal.
Terminal 3: B
Terminal 4: A
Terminal 5: GND
Saliyane kabel sing bener saka garis RS485, modul antarmuka khusus pabrikan dibutuhake kanggo integrasi menyang macem-macem sistem otomasi: kanggo sistem basis KNX, extension RS485 (contone minangka gateway KNX-TP / RS485) kasedhiya, sing ngowahi level lan protokol ing antarane bis KNX lan piranti RS485. Ing sistem Loxone, ekstensi resmi Loxone RS485 digunakake, sing digabungake langsung menyang lingkungan Loxone Miniserver.
Nalika milih antarmuka cocok, iku utamané penting kanggo mesthekake yen iku ora gateway Modbus RS485, nanging transparent, serial RS485 gateway. Südwind nggunakake protokol proprietary sing ora cocog karo standar Modbus.
Setelan ngalih DIP
Nalika kontrol tengah dumadi liwat KNX utawa Loxone, sistem rampung njupuk alih tugas panel tembok. Unit utama dikonfigurasi minangka master kanthi panel tembok.
Kabeh unit liyane ing sistem disetel minangka budak liwat switch DIP. Gumantung ing aplikasi, contoneampMinangka sumber lan sistem udara exhaust, unit budak bisa dioperasikake kanthi sinkron utawa ora sinkron.
Master mit Fernbedienung = Master karo remot kontrol
Master mit Wandpanel = Master karo panel tembok
Budak gegenläufig Master = Abdi - Master operate asynchronously
Budak gleichläufig Master = Abdi -Master operate synchronous
Parameterisasi
Parameter komunikasi serial sing bakal dikonfigurasi ing ekstensi RS485:
- baud rate 9600 [bit/s]
- 8 bit data
- 1 mandeg
- ora paritas
Pesen dikirim saka kontrol tengah menyang kabeh unit sing disambungake kanthi interval 500 ms.
Pesen kasebut kalebu urutan bita ing panomeran heksadesimal (hex-nomer). Saben unsur, kayata \x02 utawa \x30, nggambarake bait siji ing format heksadesimal.
Pitakonan status
Inquiry status dikirim saka kontrol pusat lan dievaluasi dening unit Master. Nalika ngirim pitakonan iki, kontrol tengah mandheg ngirim pesen kanggo 3 detik, kanggo mesthekake yen baris kasedhiya.
| Status | dhawuh |
| Pitakonan status | \x02\x30\x32\x30\x32\x03 |
Yen ora ana sensor utawa status sing aktif, unit Master mbales pesen dawane 11 bita ing format heksadesimal ing ngisor iki: \x02\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x03.
Byte pisanan \x02 nyetel wiwitan pesen (bingkai wiwitan) lan ngiring dening rong bait \x30\x30 makili "pesen status" (\x30 cocog karo "0" ing ASCII-karakter).
8 bita ing ngisor iki makili register status tunggal. Saben bait iki cocog karo pesen tartamtu. Mung papat ndhaptar pisanan digunakake: Register pisanan stands kanggo sensor twilight, kaloro lan katelu kanggo weker pangowahan Filter lan siji kanggo weker asor. A byte ditampa \x30 cocog karo "0" ing kode ASCII. Tegese, yen sensor utawa status sing cocog ora aktif. \X31 cocog karo "1" lan nuduhake status aktif.
Pesen dipungkasi kanthi byte \x03 yaiku bit mandeg (bingkai pungkasan) lan nyetel pungkasan transmisi.
Weker pangowahan filter bisa direset kanthi prentah.
Pesen
Ing paragraf ing ngisor iki diterangake printah siji lan fungsi sing cocog. Kaya kasebut ing ndhuwur, prentah kudu dikirim saka unit kontrol tengah menyang kabeh unit sing disambungake kanthi interval 500 ms.

Petunjuk pemrograman
Unit kasebut kudu ngganti arah rotasi ing interval tartamtu, kanggo entuk pemulihan panas sing paling apik: asupan 60 detik banjur ngaso 10 detik.
Banjur ekstraksi 60 detik banjur ngaso 10 detik liyane. Siklus iki njamin pertukaran udara sing efisien bebarengan karo pemulihan panas. Ing wayah sore sensor twilight terpadu ngidini ngalih kanthi otomatis menyang mode wengi.
Ngatasi masalah
Yen ora ana komunikasi sing disetel, saklar saluran A lan saluran B (garis A / B ing RS485) bisa mbantu. Kajaba iku, priksa manawa resistor terminating wis disetel kanthi bener, utamane ing stasiun pungkasan ing bis, supaya ora ana refleksi sinyal lan gangguan komunikasi.
