SIEMENS 6ES7972-0DA00-0AA0 SIMATIC DP

• Isetyenziselwa ukudibanisa ii-nodes ze-PROFIBUS kwintambo yebhasi ye-PROFIBUS
• Ukufakelwa okulula
• Iiplagi zeFastConnect ziqinisekisa amaxesha okuhlanganisa amafutshane kakhulu ngenxa yetekhnoloji yazo yokususa ubushushu
• Ii-resistors eziphelisayo ezidityanisiweyo (ezingekho kwimeko ye-6ES7972-0BA30-0XA0)
• Izihlanganisi ezineesokhethi ze-D-sub zivumela uqhagamshelo lwe-PG ngaphandle kofakelo olongezelelweyo lwee-nodes zenethiwekhi

Isicelo

Izihlanganisi zebhasi ze-RS485 ze-PROFIBUS zisetyenziselwa ukudibanisa ii-nodes ze-PROFIBUS okanye izixhobo zenethiwekhi ye-PROFIBUS kwintambo yebhasi ye-PROFIBUS.

Uyilo

Kukho iinguqulelo ezahlukeneyo zesixhumi sebhasi, nganye ilungiselelwe izixhobo eziza kuqhagamshelwa:

• Isixhumi sebhasi esine-axial cable outlet (180°), umz. kwiiPC kunye nee-SIMATIC HMI OPs, ukuze kufikelele kumazinga okudlulisela ukuya kuthi ga kwi-12 Mbps kunye ne-integrated bus terminating resistor.
• Isixhumi sebhasi esine-outlet yentambo ethe nkqo (90°);

Esi sixhumi sivumela i-outlet yentambo ethe nkqo (enojongano lwe-PG okanye engenalo) ukuze kufikelele kumazinga okudlulisela ukuya kuthi ga kwi-12 Mbps ene-integral bus terminating resistor. Kwizinga lokudlulisela le-3, 6 okanye 12 Mbps, intambo ye-plug-in ye-SIMATIC S5/S7 iyafuneka ukuze kuqhagamshelwe phakathi kwesixhumi sebhasi esine-PG-interface kunye nesixhobo sokucwangcisa.

• Isixhumi sebhasi esine-outlet yekhebula engama-30° (inguqulelo engabizi kakhulu) ngaphandle kwe-interface ye-PG yamanqanaba okudlulisela ukuya kuthi ga kwi-1.5 Mbps kwaye ngaphandle kwe-resistor yokuphelisa ibhasi edibeneyo.
• Isixhumi sebhasi sePROFIBUS FastConnect i-RS 485 (i-cable outlet engu-90° okanye i-180°) esinamazinga okudlulisela afikelela kwi-12 Mbps ukuze kube lula kwaye kube lula ukuhlanganisa kusetyenziswa ubuchwepheshe bokuxhulumanisa ukufudumeza (kwiintambo eziqinileyo neziguquguqukayo).

Umsebenzi

Isixhumi sebhasi sixhunywe ngqo kwi-interface ye-PROFIBUS (i-9-pin Sub-D socket) yesitishi se-PROFIBUS okanye icandelo lenethiwekhi ye-PROFIBUS. Intambo ye-PROFIBUS engenayo nephumayo iqhagamshelwe kwiplagi kusetyenziswa ii-terminals ezi-4.
