Lub hauv paus rau phau ntawv
Tsis ntev los no, ntau cov PLC cov neeg tsim tawm tau nug cov lus nug txog cov npav tsa suab thiab cov tswj hwm kev tswj hwm. Coob leej ntau tus tsis paub meej txog qhov sib txawv thiab kev sib txuas ntawm lawv. Niaj hnub no, Kuv xav qhia rau koj qhov sib txawv ntawm PLCs, cov npav tswj cov lus tsa suab, thiab yuav ua li cas thiaj xaiv txoj cai.
Qhov nyob nram qab
Nrog kev nce qib ntawm thev naus laus zis thev naus laus zis, cov neeg hlau muaj kev lag luam tau thov dav dav ntau. PLCS tsis yog qhov yooj yim programmable logic controllers. Ntau cov tuam ntxhab tau qhia lawv tus kheej cov lus tsa suab tswj - hom plcs kom ua tiav qee yam kev txav suab paj nruag tswj haujlwm. Nyob rau tib lub sijhawm, daim npav tswj cov lus tsa suab thiab cov lus tsa suab lus tseem tab tom muaj kev loj hlob sai.
Rau lub tshuab hluav taws xob, yog tias peb tes num koom rau kev tawm suab {{}}}}}}}}} Pe} Peb yuav tsum xub xaiv lub cev muaj zog tsim nyog. Yog tias yuav tsum muaj tseeb, peb feem ntau xaiv ib lub cev muaj zog; Txwv tsis pub, peb tuaj yeem siv lub cev muaj zog stepper rau kev tsa suab tswj. Txawm li cas los xij, txawm hais tias nws yog lub cev muaj zog stepper lossis lub cev muaj zog servo, nws yog ib txwm ua khub nrog nws tus tsav tsheb coj. Cov lus nug tom ntej yog: Peb tuaj yeem tswj cov stepper (servo) motors siv stepper (servo) cov tsav tsheb?
Cov kev daws teeb meem
Feem ntau, peb muaj cov kev xaiv hauv qab no:
1. Siv PLC rau kev tswj hwm.Feem ntau PLCs ntawm kev ua lag luam Txhawb Kev Tswj Xyuas Kev Tawm Tsam, nrog ntau muaj peev xwm nthuav dav txog 32 axes. Ua raws li tus tsav tsheb, kev tswj txoj hauv kev tuaj yeem suav cov kev tswj cov mob ntsws, kev tswj tsheb npav, lossis tswj kev tswj hwm.
2. Siv daim npav tsa suab rau kev tswj hwm.Daim npav tswj hwm yog tus tswj hwm tshwj xeeb tsim rau cov lus tsa suab, muaj peev xwm tswj tau nce mus txog 256 tus axes. Tswjhwm Phaib Txom Ntsig yuav tsum muaj PC program programming.
3. Siv cov lus tsa suab rau kev tswj hwm.Tus yuam sij sib txawv ntawm cov lus tsa suab thiab daim npav tswj kev tsa suab yog tias cov lus tsa suab tuaj yeem ua haujlwm ywj pheej ntawm lub PC. Tom qab kev zov me nyuam, tus lej tuaj yeem rub tawm ncaj qha rau tus maub los kom tswj tau cov tsav.
Kev xaiv
Yog li, peb yuav ua li cas thiaj xaiv? Cia peb saib lawv qhov sib txawv thiab kev sib txuas.
Ua ntej, nws yog ib qho tseem ceeb kom paub meej tias puas yog PLC, suab tswj hwm, lossis cov lus tsa suab tswj hwm, thaum tseem txhawb nqa cov tswv yim / oputed paib tswj / outputioned kev tswj / tso zis kos npe. Lub ntsiab sib txawv yog raws li hauv qab no:
1. PLCS Excel ntawm Logic I / O tswj, ua rau nws yooj yim siv cov kev tswj hwm cov kev tswj hwm. Txog kev tswj cov lus tsa suab, qis {{-}}} Cov zis ceev, thiab CC - link.
2. Daim npav tswj hwm tau raug teeb tsa hauv PC tus tswv tsev ntawm PCI qhov, lossis txuas nrog tus tswv tsev PC ntawm eternet; Kev txhim kho yog ua siv siab siv siab-}} Cov qib kawm qib ntxiv xws li c}, vb, vb.net, thiab Lab.NtView; Thaum lub sijhawm ua haujlwm, tus tswj daim npav API Interface Functions tau muab siv los tswj cov peev txheej tswj hwm; Cov Ntawv Tswj Tswj Xyuas yog faib rau hauv cov mem tes-}}} hom npav feem ntau kim dua pulse {}} daim npav.
3. PLCS muaj qhov zoo xws li kev ua haujlwm txhim khu kev qha thiab lawv cov lus tsa suab tau yooj yim. Hauv PlC daim ntawv thov, lub ntsiab interface yog plc + hm no hmi, uas txwv txoj kev pom ntawm lub peev xwm ua tau. Yog li ntawd, sab saud {4 4}}}}} Kev siv qib raws li PLCS tau dhau los ua ntau dhau;
4. Cov ntawv tsa suab tswj tau tuaj yeem rub tawm cov haujlwm muaj zog ntawm PCs, tshuab ua haujlwm, tshuab pom kev ua haujlwm; Lawv siv FPGA + DSP / Caj npab + DSP kev ua haujlwm ua haujlwm kom ua tiav siab thiab}} {{{{{{{4 4} Taug kev, suab kev nrhiav, pooj tswj, thiab lwm yam).
5. Lub algorithms ntawm cov lus tsa suab thiab cov npav tswj cov lus tsa suab yuav luag zoo tib yam. Qhov sib txawv tseem ceeb ntawm lawv yog tias cov duab tswj hwm cia siab rau PC programming, thaum suab controllers tuaj yeem sau ncaj qha sau thiab rub tawm cov kev pab cuam.
6. Nrog rau kev siv lub zeem muag ntawm tshuab, tswj kev tswj hwm thiab tshuab lub zeem muag tau ua ke tau zoo. Piv rau siv cov npav tswj cov lus tsa suab, cov hau kev no tuaj yeem txo cov nqi kho vajtse.
Hauv cov ntsiab lus, PLCS yog ntau tshaj plaws ntawm kev tswj kev tswj hwm thiab tsawg dua ntawm cov ntawv tsa suab thiab cov lus tsa suab tswj tau ntau dua rau kev tswj cov lus tsa suab thiab tsawg dua ntawm kev tswj cov lus tsa suab thiab tsawg dua ntawm kev tswj cov lus tsa suab thiab tsawg dua ntawm kev tswj cov lus tsa suab. Ib qho ntxiv, cov ntawv tsa suab tswj cov npav thiab cov lus tsa suab tau muaj cov kev pheej hmoo siab rau cov neeg tsim khoom. Yog li ntawd, cov neeg siv yuav tsum xaiv txoj kev daws teeb meem uas tsim nyog raws lawv cov kev xav tau.
