Khoom nta

Allen Bradley 1734-485ASC yog ib qho kev ntseeg siab RS-485 serial kev sib txuas lus module tshwj xeeb tsim los rau Allen Bradley's Point I/O faib I/O system. Nws ua haujlwm raws li qhov txuas tseem ceeb ntawm Point I/O modules thiab cov khoom siv hauv kev lag luam-xws li zaus converters, smart meters, thiab thib peb -PLCs- ua kom ruaj khov bidirectional cov ntaub ntawv pauv hauv automation setups. Nws txhawb ntau txoj kev siv dav hauv kev lag luam, suav nrog Allen Bradley's proprietary DF1 (tag nrho-duplex/ib nrab- duplex) thiab DH-485 raws tu qauv, nrog rau universal Modbus RTU raws tu qauv (nyob rau hauv ob qho tib si neeg siv thiab server hom). Qhov no txhais tau tias nws tuaj yeem txuas nrog Allen Bradley cov cuab yeej thiab cov cuab yeej thib peb, txo cov teeb meem kev sib raug zoo hauv kev sib xyaw ua ke.

Allen Bradley 1734-485ASC muaj cov ntaub ntawv teeb tsa (7 lossis 8), nres cov khoom (1, 1.5, lossis 2), thiab parity (tsis muaj, txawm, lossis khib). Tus nqi baud muaj li ntawm 1200 bps rau 115200 bps. Txhawm rau txo cov teeb meem kev xav thiab lav cov ntaub ntawv hloov pauv tsis tu ncua, lub module muaj ib qho RS -485 qhov chaw sib txawv nrog A +, B-, thiab GND pins nrog rau kev sib xyaw 120Ω txiav tawm resistor uas tuaj yeem qhib los ntawm kev hloov pauv lossis software. Nws tuaj yeem ua tau ntev txog 32 qhov ntawm lub tsheb npav yam tsis muaj qhov rov ua dua, thiab nws qhov kis tau tus mob mus txog 1200 meters ntawm 9600 bps (nrog shielded twisted-pair cable) thiab kwv yees li 150 meters ntawm 115200 bps.

Allen Bradley 1734-485ASC yog sib xws nrog Allen Bradley's Logix series controllers, xws li ControlLogix, CompactLogix, thiab FlexLogix, thiab mounts ntawm 35 mm standard DIN rail (yuav tsum muaj Point I/O puag). Studio 5000 Logix Designer software (version 24 lossis siab dua) yog siv rau kev teeb tsa, ua kom muaj kev hloov pauv hauv online yam tsis muaj kev txwv lub kaw lus. Thaum ua ke nrog lub hauv paus kub-swappable (xws li 1734-TB3H), nws pab txhawb kev sib pauv kub kom yooj yim ntxiv, tso cai hloov pauv hloov thaum lub kaw lus tau siv los txo qis qis.

Cov kev ceev faj

Ua ntej, thaum txhim kho Allen Bradley 1734-485ASC, ib txwm siv qhov sib xws Point I / O puag (xws li 1734-TB, 1734-TB3, lossis 1734-TB3H). Lub hwj chim mov thiab teeb liab kis tau tus mob yuav cuam tshuam yog hais tias lub module yog mounted ncaj qha rau ntawm ib tug 35 hli DIN rail tsis muaj lub hauv paus. Ua kom lub hauv paus ruaj khov rau txoj kev tsheb ciav hlau kom tsis txhob muaj teeb meem hluav taws xob lossis kev sib txuas lus tsis zoo vim muaj kev sib txuas tsis zoo.

Ua tib zoo phim lub davhlau ya nyob twg thaum xaim RS-485 chaw nres nkoj: txuas lub module's X (RS-485 A+) mus rau thaj chaw cov khoom siv sib piv A+ davhlau ya nyob twg, Y (RS-485 B-) rau B-, thiab G rau teeb liab av (GND). Ua ntej yuav qhib, muab ob npaug rau - xyuas cov xaim vim tias hloov A + thiab B - yuav cuam tshuam kev sib txuas lus. Rau RS-485 kev sib txuas, siv cov hlua khi hlua khi (xws li Belden 9841) kom txo EMI; txhawm rau tiv thaiv cov teeb liab cuam tshuam, khaws cov cable kom deb ntawm cov kab hluav taws xob siab thiab lub cev muaj zog. Ntxiv ib qho RS-485 repeater (xws li Allen Bradley 1784-KTCX) kom muaj ntau yam thiab khaws cov teeb liab zoo rau lub tsheb npav ntev dua 150 meters (ntawm tus nqi siab baud) lossis ntau dua 32 nodes. Pab kom lub built-in 120Ω txiav tawm resistor (ntawm DIP hloov lossis Studio 5000 software) thaum lub module nyob rau ntawm qhov kawg ntawm RS-485 tsheb npav-qhov no txo cov teeb liab kev xav thiab txhim kho cov ntaub ntawv xa mus.

FAQ
