CAN Termination, 120 Ohm, DB9

Tsim los rau tsheb CAN tsheb npav sib txuas lus. Yuav siv tau rau cov khoom siv xws li ZLG-USBCAN, VECTOR-CAN rooj, Vechle SPY thiab lwm yam ncaj qha.

Ntawm CAN High (pin 7) thiab CAN Tsawg (tus pin 2) muaj qhov ua tau-nyob rau hauv 120 Ohm tuaj yeem txiav tawm cov resistor.

Termination thiab Bias Resistors

Ib txwm RS-485 network (piv txwv li MPI, DP) yuav tsum siv cov kev tawm tsam thiab kev tsis ncaj ncees. Kev txiav tawm thiab kev tsis sib haum xeeb kuj tseem tuaj yeem raug tshem tawm rau cov xov tooj luv luv, kev kuaj ib ntus lossis kuaj.

Bias resistor: Bias resistor yog siv los xyuas kom meej qhov kev sib raug zoo ntawm A thiab B teeb liab thaum qhov teeb meem hluav taws xob nyuaj, thiab kom ntseeg tau tias muaj kev ntseeg siab ntawm "0" thiab "1" signals.

Siemens 'PROFIBUS network connectors twb muaj built-in txiav thiab kev tsis ncaj ncees resistors uas tau yooj yim qhib los yog tawm nrog ib tug hloov. Lub davhlau ya nyob twg tsis kam hloov ntawm lub ntsaws ntawm lub network davhlau ya nyob twg yuav tsum muab tso rau hauv txoj haujlwm "ON"; lub davhlau ya nyob twg tsis kam hloov ntawm lub ntsaws ntawm qhov chaw nruab nrab yuav tsum muab tso rau hauv "OFF" txoj haujlwm.

Cov txiaj ntsig ntawm kev txiav tawm thiab kev tsis ncaj ncees yog ua raws li Siemens cov chaw nres nkoj sib txuas lus thiab PROFIBUS cables.

Los ntawm kev kaw lub davhlau ya nyob twg tsis kam hloov ntawm lub network ntsaws hauv lub network, nws yooj yim heev los txiav tawm cov teeb liab kis ntawm ib feem ntawm lub network tom qab lub ntsaws.

Thaum sib txuas lus nrog lwm yam khoom siv (siv PROFIBUS cable), qhov chaw sib txuas lus ntawm lwm tus neeg yuav tsis yog hom D-SUB9 tus pin, lossis cov lus txhais tus pin yuav txawv kiag li. Piv txwv li, Siemens MM4x0 inverter, RS-485 chaw nres nkoj kev sib txuas lus txais daim ntawv xaim hluav taws xob. Hauv qhov no, nws yog qhov tsim nyog los txuas lub davhlau ya nyob twg resistor. Siemens tuaj yeem muab cov kev tiv thaiv sab nraud tsis tu ncua. Rau lwm cov khoom siv, nws tuaj yeem ua tau raws li cov ntaub ntawv kev tshaj lij hauv "S7-200 Kev Tswj Xyuas Txheej Txheem".

Qhov loj ntawm lub davhlau ya nyob twg tsis kam thiab kev tsis sib haum xeeb nyob rau hauv Siemens network plug sib tw cov yam ntxwv impedance ntawm Siemens PROFIBUS cable. Nws raug pom zoo kom cov neeg siv siv Siemens PROFIBUS cable thiab txuas lub network. Ntau yam teeb meem yuav zam tau.
