1, HMI tuaj yeem txuas tau rau PLC?
Tsis yog li ntawd. HMI cov khoom lag luam yog tsim los daws cov teeb meem ntawm cov txheej txheem ntawm lub computer, tab sis nrog kev sib txuas lus ntawm cov chaw nres nkoj serial, yog li ntev tau muaj Kev sib txuas lus muaj lub peev xwm ntawm kev tswj khoom siv, xws li cov kev ntsuas hloov kho, thiab lwm yam.
2, tib neeg-tshuab interface thiab cov neeg feem ntau hais tias "kov screen" Dab tsi yog qhov sib txawv?
Nruj me ntsis kev hais lus, ob tus yog qhov sib txawv. Vim tias "kov screen" tsuas yog kho vajtse ib feem uas yuav siv rau cov khoom siv nas thiab keyboard rau cov khoom siv, nruab rau sab xub ntiag ntawm cov khoom siv tawm; Thaum tib neeg-tshuab cov khoom interface yog hom tib neeg-khoos phis tawj cov cuab yeej siv uas muaj cov khoom siv kho vajtse thiab software. Hauv kev lag luam, tib neeg feem ntau muaj kov cov tswv yim ntawm tib neeg-tshuab interface khoom hu ua "kov screen", tab sis qhov no tsis yog kev tshawb fawb.
3, Tib neeg-tshuab cov khoom lag luam interface, txawm hais tias muaj ib lub operating system?
Txhua tus neeg-tshuab interface cov khoom muaj cov txheej txheem software ntawm cov txheej txheem, cov txheej txheem yuav tsum muaj kev ua haujlwm me me kom tswj hwm txoj haujlwm ntawm cov txheej txheem software. Ntsiav tshuaj PC-raws li cov khoom lag luam zoo HMI, feem ntau siv WinCE, Linux thiab lwm lub hom phiaj empedded operating system.
4, tib neeg-tshuab interface thiab software software, dab tsi yog qhov sib txawv?
Hmi cov khoom lag luam, feem ntau hu ua "kov screen", suav nrog HMI kho kom zoo nkauj software, feem ntau, cov khoom sib txawv ntawm cov cuab yeej loj yog PLC. Lub software teeb tsa tau khiav hauv PC kho vajtse platform, Windows operating system nyob rau hauv ib lub cav software dav dav, thiab PC lossis kev tswj hwm kev tswj hwm kuj muaj HMI cov khoom lag luam; General Configuration software los txhawb ntau ntau ntawm cov khoom siv, xws li ntawm lub pob hluav taws xob, cov khoom siv hluav taws xob, feem ntau yuav rov qab ua kom nrawm dua (feem ntau cuam tshuam rau qhov nrawm thiab cia muaj peev xwm cia ), software dav dav kuj tseem muaj zog heev, muaj feem xyuam rau cov kev soj ntsuam loj-teev.
5, Puas muaj kev sib txuas lus ntawm lub cuab yeej yuav tsum muaj peev xwm txuas nrog tib neeg-tshuab interface khoom lag luam?
Nws yuav tsum yog li ntawd. Vim tias cov khoom HMI muaj ntau ntawm cov tsav tsheb sib txuas lus ntau ntau rau kev xaiv; Feem ntau, ntev li ntev yog HMI screen configuration software kom xaiv cov neeg tsav tsheb sib txuas nrog lub npe sib txuas lus ntawm HMI thiab ntaus ntawv. Yog tias software teeb tsa ntawm cov khoom xaiv hmi tsis muaj cov khoom siv sib txuas lus rau cov khoom lag luam uas yog cov khoom lag luam Lub HMI cov chaw tsim khoom lag luam los npaj tus neeg tsav tsheb sib txuas lus rau lub cuab yeej sawv cev ntawm cov khw.
6, PC Plus kov lub vijtsam, tuaj yeem sib txuas lus ncaj qha nrog PLC kom ua tiav HMI ua haujlwm?
Tau kawg. Txawm li cas los xij, peb kuj yuav tsum tau npaj cov tshuaj zoo li HMI hauv kev txiav txim kom lub PC ua cov khoom lag luam tiag.
7, Tib neeg-tshuab interface tsuas yog txuas tau rau lwm cov khoom siv los ntawm cov qauv kev sib txuas lus serial kev sib txuas lus?
Feem ntau cov xwm txheej no yog rooj plaub. Txawm li cas los xij, nrog kev txhim kho ntawm lub khoos phis tawj thiab cov thev naus laus zis enterface ntawm HMI muaj zog thiab muaj zog dua. Ntxiv rau cov tsoos serial (Rs232, RS422 / RS422 / RS422 / RS485) Kev sib txuas lus hauv network, lawv tuaj yeem muaj chaw nres nkoj hauv network, USB chaw nres nkoj thiab lwm yam cuam tshuam txuas nrog Rau cov khoom tswj kev tswj kom ua tiav tib neeg lub tshuab kev sib cuam tshuam ntawm cov khoom siv.
8, Yav tom ntej kev txhim kho yav tom ntej ntawm tib neeg-tshuab interface?
Nrog rau kev txhim kho cov kab ncig thiab lub computer interface cov khoom lag luam ntawm cov haujlwm siab, nruab nrab yog qhov pom tseeb, HMi ntau dua; 5.7 nti saum toj no HMI cov khoom lag luam yuav yog txhua yam xim, tshuaj ntsuam lub neej yuav muaj ntev dua. Vim tias qhov kev txo qis hauv tus nqi ntawm cov khoom siv computer, , kev sib koom tes network, software pab txhawb nqa tau muaj txiaj ntsig zoo dua yav tom ntej ntawm kev txhim kho Hmi cov khoom lag luam. Ntawm chav kawm, qhov loj me (zaub loj dua tsawg dua 5.7 nti) HMi, nrog rau kev ua haujlwm ntxiv ntawm nws txoj haujlwm), nws yuav tau siv dav hauv cov tshuab me me thiab cov cuab yeej siv rau tib neeg-khoos phis tawj sib cuam tshuam.
