Ipulaki yokuxhuma i-SIEMENS 6ES7972-0BA42-0XA0 SIMATIC DP ye-PROFIBUS

Ukubuka konke

• Isetshenziselwa ukuxhuma ama-node e-PROFIBUS kukhebula lebhasi le-PROFIBUS
• Ukufakwa okulula
• Ama-plug e-FastConnect aqinisekisa izikhathi zokuhlanganisa ezimfushane kakhulu ngenxa yobuchwepheshe bawo bokufudumeza nokufaka umswakama
• Ama-resistors okuqeda ahlanganisiwe (hhayi esimweni se-6ES7972-0BA30-0XA0)
• Izixhumi ezinezixhumi ze-D-sub zivumela uxhumano lwe-PG ngaphandle kokufakwa okwengeziwe kwama-node enethiwekhi

Isicelo

Izixhumi zebhasi ze-RS485 ze-PROFIBUS zisetshenziselwa ukuxhuma ama-node e-PROFIBUS noma izingxenye zenethiwekhi ye-PROFIBUS kukhebula lebhasi le-PROFIBUS.

Umklamo

Kunezinhlobo eziningana ezahlukene zesixhumi sebhasi ezitholakalayo, ngayinye ilungiselelwe amadivayisi axhunywe:

• Isixhumi sebhasi esine-axial cable outlet (180°), isib. kuma-PC nama-SIMATIC HMI OP, ukuze kube namazinga okudlulisa afinyelela ku-12 Mbps ane-resistor ehlanganisiwe yokuqeda ibhasi.
• Isixhumi sebhasi esine-outlet yekhebula eqonde phezulu (90°);

Lesi sixhumi sivumela i-outlet yekhebula eqondile (ene-interface ye-PG noma engenayo) yamazinga okudlulisa afinyelela ku-12 Mbps ane-resistor yokuqeda ibhasi ehlanganisiwe. Ngesilinganiso sokudlulisa esingu-3, ​​6 noma 12 Mbps, ikhebula le-plug-in le-SIMATIC S5/S7 liyadingeka ukuze kuxhunywe phakathi kwesixhumi sebhasi ne-interface ye-PG kanye nedivayisi yokuhlela.

• Isixhumi sebhasi esine-outlet yekhebula engu-30° (inguqulo eshibhile) ngaphandle kwesixhumi esibonakalayo se-PG samazinga okudlulisa afinyelela ku-1.5 Mbps futhi ngaphandle kwe-resistor yokuqeda ibhasi ehlanganisiwe.
• Isixhumi sebhasi se-PROFIBUS FastConnect i-RS 485 (i-cable outlet engu-90° noma engu-180°) esinamazinga okudlulisa afinyelela ku-12 Mbps ukuze kube lula futhi kube lula ukuhlanganisa kusetshenziswa ubuchwepheshe bokuxhumanisa ukufudumeza (kwezintambo eziqinile neziguquguqukayo).

Umsebenzi

Isixhumi sebhasi sixhunywe ngqo ku-interface ye-PROFIBUS (isokhethi le-Sub-D elingu-9-pin) lesiteshi se-PROFIBUS noma ingxenye yenethiwekhi ye-PROFIBUS. Ikhebula le-PROFIBUS elingenayo neliphumayo lixhunywe ku-plug kusetshenziswa ama-terminal angu-4.
