Video: Cov lus qhia txawv ntawm PLC yog dab tsi?
2024 Tus sau: Lynn Donovan | [email protected]. Kawg hloov kho: 2023-12-15 23:47
Qee lwm cov lus qhia PLC yog:
- Relay-hom (Basic) cov lus qhia : I, O, OSR, SET, RES, T, C.
- Kev tuav ntaub ntawv Cov lus qhia :
- Cov ntaub ntawv txav Cov lus qhia : MOV, COP, FLL, TOD, FRD, DEG, RAD (degrees rau radian).
- Kev sib piv cov lus qhia : EQU (sib npaug), NEQ (tsis sib npaug), GEQ (ntau dua lossis sib npaug), GRT (ntau dua).
Yog li ntawd, dab tsi yog cov lus qhia hauv PLC?
A PLC feem ntau yog siv los tswj cov tshuab. Ib qho program sau rau a PLC muaj hauv paus ntawm cov lus qhia tig rau thiab tawm cov zis raws li cov txheej txheem nkag thiab cov kev pab cuam sab hauv. Hauv qhov kev hwm no, nws zoo ib yam li kev siv lub khoos phis tawj txheem siv li cas.
Tom qab ntawd, lo lus nug yog, koj ua li cas rau PLC? Cov txheej txheem ib kauj ruam-los-kauj ruam rau Programming PLC Siv Ladder Logic
- Kauj Ruam 1: Tshawb xyuas thiab Tau Txais Lub Tswv Yim ntawm Kev Tswj Xyuas Daim Ntawv Thov.
- Kauj Ruam 2: Sau tag nrho cov xwm txheej thiab tau txais tus qauv siv Flowchart.
- Kauj ruam 3: Qhib thiab teeb tsa PLC Programming Software.
- Kauj ruam 4: Ntxiv cov Rings yuav tsum tau thiab chaw nyob rau lawv.
Kuj Paub, lub npe muab rau daim ntawv teev cov lus qhia PLC yog dab tsi?
Cov npe qhia (los yog ILs) yog ib qho ntawm tsib PLC Cov lus programming txhais los ntawm IEC 61131-3 tus qauv. (Lwm tus yog ladder logic diagrams, function block diagrams, sequential function charts, and structured text.)
Daim duab PLC yog dab tsi?
PLC coj cov lus qhia nkag rau hauv daim ntawv ntawm tus ntaiv daim duab los yog computer software cov lus qhia. Cov lus qhia no tau txiav txim siab hauv CPU thiab CPU muab cov cim sib txawv los tswj lossis ua haujlwm ntau yam khoom siv. Thaum cov cuab yeej no hloov lawv txoj haujlwm lossis ua rau hloov pauv hloov pauv.

Dab tsi yog qhov txawv ntawm cov khoom taw qhia cov qauv database thiab cov qauv kev sib raug zoo?
Qhov sib txawv ntawm kev sib raug zoo database thiab cov khoom taw qhia cov ntaub ntawv yog tias cov ntaub ntawv sib txheeb cov ntaub ntawv khaws cov ntaub ntawv nyob rau hauv daim ntawv ntawm cov ntxhuav uas muaj kab thiab kab. Hauv cov khoom taw qhia cov ntaub ntawv cov ntaub ntawv khaws cia nrog rau nws cov haujlwm uas ua los yog nyeem cov ntaub ntawv uas twb muaj lawm. Cov no yog qhov sib txawv hauv paus
Puas txhais tau tias yog kev sib raug zoo ntawm cov khoom ntawm ib yam khoom thiab lub peev xwm ntawm tus neeg sawv cev uas muab cov lus qhia rau kev siv cov khoom?
Kev them nyiaj yog kev sib raug zoo ntawm cov khoom ntawm ib yam khoom thiab lub peev xwm ntawm tus neeg sawv cev uas txiav txim siab seb qhov khoom siv tau li cas
Dab tsi yog cov ntsiab lus ntawm cov kab lus taw qhia?
Hauv kev sau ntawv, kev taw qhia, uas tuaj yeem yog ib lossis ob kab lus, qhia lub ntsiab lus. Muaj peb ntu rau kev taw qhia: cov lus qhib, cov kab lus txhawb nqa, thiab cov ntsiab lus pib
Dab tsi yog qhov sib txawv tseem ceeb ntawm kev sib txuas lus tsis sib xws thiab kev sib txuas lus taw qhia?
1. Hauv kev sib txuas lus tsis muaj kev sib txuas lus tsis tas yuav tsim kev sib txuas ntawm qhov chaw (sender) thiab qhov chaw (receiver). Tab sis nyob rau hauv kev sib txuas-taw qhia kev sib txuas lus kev sib txuas lus yuav tsum tau tsim ua ntej hloov cov ntaub ntawv
Cov lus txib dab tsi yuav qhia cov ntsiab lus ntawm Nvram ntawm kev hloov pauv?
Cov lus txib uas yuav tso saib cov ntsiab lus tam sim no ntawm cov tsis-volatile random-access memory (NVRAM) yog: qhia kev pib teeb tsa. Ntawm qhov screen koj yuav pom cov hauv qab no: 'Hloov #show startup-configuration
