Cov duab ntaiv , los yog Relay Ladder Logic (RLL), yog thawj programming lus rau programmable logic Controllers (PLCs). Ladder logic programming yog ib tug graphical sawv cev ntawm qhov kev pab cuam tsim los zoo li relay logic . Cov daim duab relay siv hluav taws xob txuas ntxiv kom pom lub suab nrov li hluav taws xob kaw.
Tsuas yog li ntawd, qhov txawv ntawm relay logic thiab ntaiv logic yog dab tsi?
Qhov loj qhov sib txawv ntawm relay logic thiab ntaiv logic yog tias relay logic yuav tsum muaj zog xaim txhua thiab txhua qhov kev tswj xyuas Circuit Court rau txhua txoj haujlwm tswj. Qhov twg ntaiv logic siv cov kev pab ntawm microprocessor raws li lub npe hu ua Programmable Logic Controller (PLC).
Tom qab ntawd, lo lus nug yog, Relay daim duab yog dab tsi? Relays tswj ib lub voj voog hluav taws xob los ntawm kev qhib thiab kaw cov neeg nyob hauv lwm lub voj voog. Raws li daim duab relay show, thaum a relay kev tiv tauj ib txwm qhib (NO), muaj kev sib cuag qhib thaum lub relay tsis muaj zog. Hauv electromechanical relays (EMR), kev sib cuag raug qhib lossis kaw los ntawm lub zog sib nqus.
ntaiv logic ua haujlwm li cas?
Ntaj logic yog ib hom lus graphical programming uas txhais tau hais tias tsis yog cov ntawv nyeem, qhov programming yog ua los ntawm kev sib txuas cov duab sib txawv. Cov duab nraaj no hu ua cov cim. Ib yam ntawm cov ntse txog cov ntaiv logic cov cim yog tias lawv tau ua kom zoo li cov cim hluav taws xob.
Dab tsi yog qhov txawv ntawm PLC thiab relay?
Relays yog electro-mechanical keyboards uas muaj coil thiab ob hom kev sib cuag uas tsis yog NO & NC. Tab sis Programmable Logic Controller, PLC yog lub khoos phis tawj me me uas tuaj yeem txiav txim siab raws li qhov kev zov me nyuam thiab nws cov tswv yim & tso tawm. Yog li no a PLC tuaj yeem ua tau ntau yam haujlwm nrog tib txoj hlua nyuaj.

Daim duab twg yog hu ua daim duab sib cuam tshuam?
Daim duab kab ke qhia tau hais tias kev sib cuam tshuam ntawm ob txoj kab kev ua neej raws li lub sijhawm txiav txim ntawm cov xwm txheej. Daim duab qhia kev sib koom tes tseem hu ua daim duab sib txuas lus. Lub hom phiaj ntawm daim duab qhia kev sib koom tes yog txhawm rau hais txog cov txheej txheem ntawm cov txheej txheem, piv txwv li, yuav ua li cas ntau txoj kab hauv lub cev sib txuas
Daim duab kos duab pom kev yog dab tsi?
Visibility nyob rau hauv domain modeling class diagrams. Hauv daim duab kos duab hauv chav kawm, qhov pom kev txhais tau tias yog cov cwj pwm thiab kev ua haujlwm ntawm cov chav kawm tshwj xeeb tuaj yeem pom thiab siv los ntawm lwm cov chav kawm. Koj tuaj yeem siv cov cim kho kom zoo nkauj lossis cov ntawv cim los qhia txog qib kev pom ntawm cov cwj pwm thiab kev ua haujlwm
Dab tsi yog qhov txawv ntawm daim duab kos duab thiab graphical nthuav qhia?
Qhov no txhais tau hais tias daim duab tsuas yog ib feem ntawm daim duab. Graph yog ib tug sawv cev ntawm cov ntaub ntawv siv kab ntawm ob los yog peb axes xws li x, y, thiab z, whereas daim duab yog ib tug yooj yim pictorial sawv cev ntawm ib yam dab tsi zoo li los yog nws ua hauj lwm li cas
Dab tsi yog daim duab kos duab kev tswj xyuas qhov project?
Daim duab kos duab yog ib daim duab sawv cev ntawm txhua txoj haujlwm, lub luag haujlwm thiab kev ua haujlwm rau ib qhov project. Nws feem ntau zoo li daim duab nrog cov thawv thiab cov xub
Dab tsi yog qhov txawv ntawm lub koob yees duab digital thiab lub koob yees duab zaj duab xis?
Qhov sib txawv tseem ceeb ntawm ob yog txoj kev nws ntes cov duab. Thaum lub teeb los ntawm kev yees duab nkag mus rau hauv lub koob yees duab, lub koob yees duab digital siv lub sensor los ntes cov duab. Nyob rau hauv lub koob yees duab (lub koob yees duab analog), lub teeb ntog rau film
