Relay tswj thiab plc tswj yog ob hom kev muaj tshuab kev lag luam tswj. Lawv sib txawv ntawm ntau txoj hauv kev, suav nrog cov ntsiab lus, cov qauv, muaj nuj nqi, thiab kev siv cov xwm txheej. Cov hauv qab no yog kev sib piv ntawm ob hom kev tswj:
1. Ntsiab Cai
Relay tswj yog ib txoj kev tswj raws li hluav taws xob qeeb. Lub tshuab hluav taws xob hluav taws xob yog lub tshuab hloov pauv uas tswj hwm ntawm - tawm ntawm txoj kev tswj hwm tam sim no hauv kev paub txog kev nqus thiab tso tawm. Lub hauv paus ntsiab lus ntawm kev relay tswj yog siv cov neeg ntawm lub relay kom paub lub cav hluav taws xob hloov chaw thiab kom paub qhov kev tswj hwm ntawm cov khoom siv.
Plc kev tswj hwm yog hom kev tswj hwm raws cov txheej txheem kev tswj hwm nrog kev tswj hwm kev tswj hwm nrog PLC, thiab paub txog kev tswj hwm los ntawm kev tswj hwm cov program.
2. Txheej Txheem
Relay tswj cov kab ke feem ntau muaj kev tswj hwm txee, rov qab, cov neeg hu, laub nyees khawm, ntsuas teeb thiab lwm yam. Kev tswj hwm txee yog nruab nrog relays, cov neeg tau txais thiab lawv txuas ntxiv los ntawm cov xov tooj ntawm cov voj.
Plc tswj system feem ntau muaj ntawm PLC maub los, tib neeg / cov zis ntawm cov kab ke, lub luag haujlwm ntawm cov kab ke, lub luag haujlwm rau kev tswj hwm cov kev tswj hwm; Cov tswv yim / tso zis module yog siv rau kev sib txuas nrog rau ntawm-}} cov khoom siv kom paub cov teeb meem thiab tsim tawm; Hmi siv rau kev ua si thiab teeb tsa cov kab ke; Kev sib txuas lus interface yog siv rau kev paub txog kev sib txuas lus nruab nrab ntawm cov kab ke thiab cov cuab yeej sab nraud.
3. Kev Ua Haujlwm
Relay tswj kev ua haujlwm yog qhov yooj yim, tsuas yog siv los paub txog kev tswj hwm cov haujlwm yooj yim xws li pib thiab siv rov qab thiab ua kom nrawm dua. Vim tias muaj tsawg tus neeg relay tiv tauj, lub suab ntawm kev tswj hwm kev relay tsis zoo, thiab nws yog qhov nyuaj rau kev paub txog kev tswj hwm.
Plc kev tswj hwm yog haib, ntxiv rau kom paub txhua txoj haujlwm ntawm kev tswj hwm kev tswj, nws tseem tuaj yeem paub ntau dua cov kev tswj hwm, nws tseem tuaj yeem ua raws qib, cov ntaub ntawv thiab lwm yam. Tsis tas li ntawd, PLC tseem muaj kev nplua nuj ntawm kev sib txuas lus, tuaj yeem hloov cov ntaub ntawv nrog lwm cov khoom siv lossis cov tshuab.
4. Daim Ntawv Thov Kev Sau Npe
Relay tswj tau tsuas yog siv nyob rau hauv qee qhov kev tswj yooj yim yooj yim, xws li lub cev muaj zog pib / nres tswj, teeb tswj kev tswj hwm thiab lwm yam. Vim nws tus nqi qis, Relay tswj tseem yog qhov kev xaiv zoo rau qee cov khoom me me lossis kev tswj tau yooj yim.
Plc kev tswj yog haum rau ntau yam complex kev tswj hwm cov khoom siv, kev tswj hwm neeg hlau, cov txheej txheem tsim tau, thiab tuaj yeem tsim kho raws cov kev xav tau sib txawv.
5. Programming Txoj Kev
Txoj kev programming ntawm relay tswj feem ntau yog pom tau los ntawm kev kos duab tswj cov duab txheej txheem tswj. Cov neeg tsim qauv yuav tsum xaiv cov kev sib txuas lus zoo, cov neeg ua haujlwm thiab lwm yam raws li kev tswj hwm, thiab tom qab ntawd kos cov kev tswj hwm hluav taws xob. Txoj kev no yog intuitive thiab yooj yim to taub, tab sis nws nyuaj dua los hloov kho thiab nthuav dav.
PLC tswj tau pom tau los ntawm kev sau ntawv tswj kev kawm, xws li cov duab kos duab, thiab lwm yam. Cov neeg siv tuaj yeem xaiv cov lus tsim nyog rau kev ua haujlwm rau kev ua haujlwm raws li kev tswj hwm. Hom no tau nce siab dua thiab nthuav dav, thiab yooj yim hloov kho thiab txhim kho.
6. Kev ntseeg tau thiab muaj kev tswj hwm
Relay tswj cov tshuab muaj cov kev ntseeg tau zoo heev thiab txij nkawm. Vim tias cov neeg sib chwv tau yooj yim hnav tawm, teeb meem xws li kev tiv tauj tsis zoo yuav tshwm sim tom qab kev ua haujlwm ntev. Tsis tas li ntawd, kev ua txhaum kev kuaj mob thiab txij nkawm ntawm kev tswj hluav taws xob yog qhov nyuaj dua, xav tau cov neeg ua haujlwm tshwj xeeb los ua cov txheej txheem tshwj xeeb thiab txij nkawm.
Plc kev tswj hwm system yog ntau txhim khu kev qha thiab tswj tau.plc muaj siab anti -}}} sib cuam tshuam nyob rau hauv ib puag ncig hnyav. Ib qho ntxiv, plc muaj cov kev ua haujlwm nplua nuj, uas tuaj yeem nrhiav tau yooj yim thiab nrhiav qhov ua txhaum thiab txhim kho kev ua haujlwm ntawm lub system.
7. Scalability thiab Hloov Kho
Cov ntsuas hluav taws xob thiab txhim kho kom zoo dua ntawm kev tswj hwm kev tswj hwm tsis zoo. Vim tias muaj tsawg tus neeg ntawm kev sib cuag, thaum kev tswj hwm cov kev hloov pauv, nws yuav tsim nyog los hloov kho lub Circuit Court, nce qib ntxiv tus nqi ntawm cov system.
Plc tswj cov tshuab muaj cov khoom lag luam zoo thiab hloov kho kom zoo dua. Cov neeg siv tau yooj yim ntxiv lossis hloov cov tswv yim / tso tawm cov qauv los nthuav cov kev tswj hwm kev tswj hwm cov kab ke raws li kev tswj hwm. Tsis tas li ntawd, PlC tswj kev pabcuam tuaj yeem hloov kho thiab hloov kho raws li kev thov, uas txhim kho qhov hloov tau yooj yim ntawm cov kab ke.
8. Nqi
Relay tswj cov tshuab yog cov nqi qis thiab haum rau qee cov khoom siv me lossis kev tswj tau yooj yim. Txawm li cas los xij, tus nqi ntawm kev txhim kho ib qho kev tswj hwm kev relay tuaj yeem nce nrawm raws li yuav tsum tau tswj kom tau nce.
Plc tswj cov tshuab muaj cov nqi qis dua, tab sis vim lawv cov qib siab ntawm cov tawv nqaij thiab cov nqi ntawm txhua tus nqi ntawm PLC tswj cov tshuab yuav qis dua.
9. Kev kawm thiab kev txhawb nqa kev txhawb nqa
Relay tswj cov tshuab muaj cov kev kawm me me thiab kev txhawb nqa. Vim tias lawv cov ntsiab lus siv cov txuj ci qis, cov neeg siv tuaj yeem ua tiav lawv sai sai los ntawm tus kheej- kawm lossis kev cob qhia yooj yim.
Kev txhawb nqa thiab kev txhawb nqa kev txhawb nqa rau PLC tswj hwm yog ntau dua plentiftion. Ntau Plc Manufacturers thiab Thib Peb -} Cov Koom Tes Pab Txhawb nqa cov kev kawm thiab cov kev pab txhawb nqa cov ntaub ntawv siv tau zoo thiab cov tswv yim.
10. Cov ntsiab lus
Relay tswj thiab plc kev tswj hwm muaj lawv tus kheej thiab qhov tsis zoo, haum rau kev thov sib txawv. Relay tswj yog yooj yim, qis- tus nqi, thiab haum rau qee qhov kev xav tau yooj yim; Thaum Plc Control muaj zog, txhim khu kev qha, thiab haum rau ntau yam kev tswj hwm kev tswj hwm scenarios.
