Dab tsi yog PLC maub los?
Plc maub los, uas yog, programmable logic maub los, yog cov ntaus ntawv digital tswj tshwj xeeb tsim rau kev siv tshuab ua lag luam. Nws paub tseeb kev tshuaj xyuas lub sijhawm thiab kev tswj hwm ntawm ntau yam txheej txheem los ntawm kev pab cuam tswj hwm kev nyab xeeb, thiab muaj cov yam ntxwv ntawm kev ntseeg siab, siab thiab yooj yim txij nkawm. Plc maub los tau siv dav siv nyob rau hauv cov kab ntau lawm, ua cov cuab yeej siv, thiab lwm lub sijhawm uas yuav tsum tau muaj qhov tseeb thiab teb lub sijhawm tiag tiag.
Tus plc maub los ua haujlwm li cas?
Lub PLC maub los ua ke cov tseem ceeb xws li chav ua haujlwm ua haujlwm (CPU), cov lus qhia thiab cov qauv tso tawm, kev sib txuas lus thiab cim xeeb. Yuav ua li cas nws ua haujlwm tuaj yeem muab cov ncauj lus qhia raws li hauv qab no:
Kos sij taw qhia
Lub PLC maub los tau txais cov cim digital lossis analog cim los ntawm sensors, hloov pauv, khawm, thiab lwm yam khoom siv ntawm cov lus qhia. Cov phiaj xwm no muaj kev cuam tshuam cov xwm txheej ntawm cov chaw ua haujlwm, xws li kub, siab, ntws, qhov chaw, qhov chaw, thiab lwm yam.
Cov ntaub ntawv ua & cov kev ua haujlwm
Cov teeb liab tau sib txuas tau mus rau CPU hauv cov ntawv plc, uas ua cov ntawv sau ua qauv raws li cov ntaub ntawv ua haujlwm raws li kev ua haujlwm tau ua tiav.
Tso Tawm Tswj Tswj
Cov kev xam pom tau tswj tus actuator, xws li solenoid valve, yog li tsav tsheb ntawm cov khoom siv thiab lwm yam kev tswj hwm ntawm cov txheej txheem ntau lawm.
Qhov no kaw-Vop tswj hom raws li kev ua yeeb yaj kiab nrog kev kub ceev, muaj kev kub ntxhov thiab siab ntseeg tau.
Dab tsi yog cov cim npe tseem ceeb ntawm PLC maub los? Cov yam ntxwv ntawm txhua qhov yog dab tsi?
Tam sim no, lub ntsiab PLC maub los hom nyob rau hauv lub khw yog siemens, allen-bradley, mitsed-bradley, mitsed-bradley, modneider hluav taws xob, module kev ua haujlwm ruaj khov, thiab kev pabcuam tom qab muag. Hauv qab no kuv tau ua piv txwv kev txheeb xyuas cov hom thiab lawv cov yam ntxwv, uas tau nthuav tawm hauv cov lus hauv qab no.

Nws yog siv rau tag nrho cov txheej txheem tshuaj xyuas ntawm kev tswj hwm lub zog, txhim kho tshuab automation thiab kev tsim khoom siv kev nyab xeeb, nrog cov ntaub ntawv kev nyab xeeb thiab cov ntaub ntawv kev ntsuas siab |
Los ntawm cov kev sib piv saum toj no, nws tuaj yeem pom tau tias txhua hom ntawm PLC maub los muaj nws cov txiaj ntsig tshwj xeeb. Siemens yog tsim nyog rau kev sib koom ua ke ntawm cov tshuab nyuaj; Rockwell excely nyob rau hauv modularity thiab kev ntsuas; Mitsubishi paub txog nws qhov kev kub ceev thiab siab tiv thaiv kev cuam tshuam; Omron, ntawm qhov tod tes, muaj qhov zoo nyob rau hauv cov nqe lus ntawm tus nqi-ua hauj lwm zoo thiab yooj yim ntawm kev ua haujlwm; Kev lag luam Schneider tau ntsib qhov kev xav tau ntawm kev tswj hwm niaj hnub rau kev txawj ntse, cov ntaub ntawv tshuaj xyuas thiab saib xyuas cov chaw taws teeb.
Tus PLC tus qauv txhim kho kev ua haujlwm ntawm lub tshuab automation?
Real-time teb thiab tswj tau meej
Vim tias PLC maub los tsim nrog kev tsom mus rau cov ntaub ntawv ntawm lub sijhawm tiag tiag thiab kev tswj hwm kaw, nws cov lus teb yog feem ntau nyob hauv millisecond ntau. Qhov no kom ntseeg tau tias txhua qhov kev ua tau tuaj yeem teb thiab hloov kho kom raws sijhawm nyob rau hauv cov kab ntau heev, uas tau txhim kho tau ntau dua. Piv txwv li, hauv cov kab sib dhos hauv lag luam lossis cov khoom noj ntim khoom noj, PlC cov txheej txheem siv cov kev hloov pauv thiab ntsuas, txo qhov nqi ntawm cov khoom lag luam tsis xws luag.
Modular tsim kom txo cov txheej txheem kev sib xyaw ua ke
Feem ntau cov PLC cov tsim qauv modular tsim, thiab cov neeg siv tuaj yeem hloov tau ntxiv lossis hloov I / O Modules thiab kev sib txuas lus cov kev xav tau. Cov qauv siv no tsis yog ua kom yooj yim los nthuav cov kab ke, tab sis kuj tau pab txhawb kev saib xyuas yav tom ntej thiab hloov khoom dua tshiab. Cov neeg siv khoom cov tswv yim qhia tau hais tias cov kab ntau lawm nrog cov plc cov plc tau txo qis qis dua los ntawm ntau dua 30% ntawm qhov nruab nrab thaum nthuav dav thiab tu ncua.
Cov Ntaub Ntawv Mus Saib & Kev Tswj Xyuas Chaw Taws Teeb
Niaj hnub nimno PLC coltrollers feem ntau muaj built-in network kev sib txuas lus ua haujlwm, profibus, modbus, modbus, modbus, modbus, modbus, sib txuas lus nrog cov txheej txheem loj thiab huab platform. Nrog cov ntaub ntawv saib xyuas tiag tiag saib xyuas, cov tuam txhab tuaj yeem paub cov teeb meem hauv lub sijhawm, thiab ua kom muaj nuj nqis tiv thaiv, yog li txo cov nqi tsim khoom thiab txhim kho cov txiaj ntsig ntau.
Yuav ua li cas xaiv cov PLC maub los li cas rau koj daim ntawv teev xwm txheej?
Ua ntej, peb yuav tsum txiav txim siab qhov loj me thiab qhov sib luag ntawm cov kab ke. Rau cov tshuab tswj yooj yooj yim, ib-xaus plc maub los yuav txaus; Rau cov nyom loj-teev cov tshuab siv tau siv hluav taws xob, nws yog qhov tsim nyog los xaiv High-xaus plc cov khoom lag luam uas txhawb ntau dua I / o muaj zog ua haujlwm thiab muaj zog sib txuas lus thiab kev sib txuas lus.
Qhov thib ob, cov xwm txheej ib puag ncig thiab kev ntseeg tau tias yuav tsum tau txiav txim siab. If the application environment is harsh, such as high temperature, high humidity or dusty industrial environment, it is recommended to choose a PLC controller with anti-interference, dustproof and shockproof functions. Ib qho ntxiv, qee hom, xws li Siemens thiab Rockwell, muaj kev sib tw muaj kev ua tsis tau zoo thiab kev ntseeg tau nyob rau hauv kev ua tsis tiav tsawg dua {1}}. 01%, zoo hauv qab ntawm kev ua lag luam nruab nrab.
Hauv txoj kev no, koj tuaj yeem txiav txim siab uas cov PLC maub los koj xav tau, tab sis peb xav kom peb paub koj cov kws ua haujlwm tsim nyog rau koj, yog li kom zam koj tsis haum koj qhov koj xaiv.
Los ntawm cov ntsiab lus saum toj no, peb tuaj yeem pom tias PLC maub los, raws li cov khoom siv ceev nrawm, tab sis kuj tseem pheej siv cov qauv, cov ntaub ntawv sib xyaw ua ke, muaj kev txij nkawm ntse thiab lwm yam.
Rau cov neeg siv khoom, thaum xaiv cov PLC maub los, nws yog qhov tsim nyog los xav txog qhov loj me, kev txhawb nqa kev siv tshuaj thiab lwm yam kev xav tau ntawm Plc maub los thiab lwm yam kev siv tshuab hluav taws xob, Peb yog ib qho kev tshaj lij Hoobkas Automation Qhov chaw tsum khoom hauv Suav teb nrog ntau xyoo ntawm kev paub.
