Hauv kev lag luam automation, ntaiv logic tseem yog ib qho ntawm cov lus siv feem ntau siv; Txawm li cas los xij, rau cov khoom tswj ntau dua, cov khoom siv -kev taw qhia kev ua haujlwm yog qhov ua tau zoo heev. Cia peb pib tham txog cov khoom -oriented programming:
Object-oriented programming yog ib qho kev ua haujlwm siab tshaj plaws hauv qib siab - cov lus hauv computer. Lub tswv yim tsim qauv no tseem tuaj yeem siv rau PLC cov haujlwm hauv kev tswj hwm kev lag luam. Txawm hais tias peb tsis tuaj yeem siv tau ntau yam zoo heev ntawm cov khoom siv -kev qhia kev taw qhia- xws li "kev ua cuab yeej cuab tam"- thiab PLC hom lus yuav tsis txawm muaj cov yam ntxwv ntawm cov khoom siv -cov lus qhia kev taw qhia, cov ntsiab lus tseem ceeb ntawm cov khoom- taw qhia kev ua haujlwm yog cov chav kawm thiab cov piv txwv hauv chav kawm (piv txwv li, khoom). Peb tsuas yog yuav tsum siv cov tswv yim no. Hauv computer programming, peb yuav tsum paub daws teeb meem thiab nthuav dav qee qhov chaw los txhais cov chav kawm. Hauv kev tswj hwm kev lag luam, txawm li cas los xij, tswj cov khoom xws li lub cev muaj zog thiab cov li qub tau hais meej meej tswj pawg; peb tuaj yeem txhais cov chav kawm rau lawv ncaj qha yam tsis tas yuav tsum muaj kev paub daws teeb meem. Cov ntu hauv qab no yuav siv Siemens 'Step7 programming language thiab Schneider's Unity programming language los piav txog cov khoom-txoj kev taw qhia rau PLCs.
I. Txoj kev ua
Object-oriented programming hauv Step7 yog siv los ntawm kev ua haujlwm blocks (FB). Thaum lub ntsiab lus no los txog, tib neeg feem ntau xav txog qhov kev ua haujlwm modular uas tau hais los ntawm Siemens. Tseeb, qhov no yog tib lub tswv yim, tab sis cov ntsiab lus xws li "modularization," "cov ntaub ntawv keeb kwm yav dhau," thiab "ntau keeb kwm" qhia los ntawm Siemens tsis tas yuav tso cai rau cov neeg siv kom nkag siab meej thiab siv qhov kev tsim qauv zoo tshaj plaws.
Txawm li cas los xij, yog tias koj mus ze nws los ntawm qhov kev xav ntawm cov khoom -oriented programming, koj tuaj yeem nkag siab zoo dua ntawm tus qauv tsim no. Ib qho "FB block" raug suav tias yog "chav kawm"; nws tuaj yeem raug saib raws li kev sib koom ua ke ntawm cov cai rau cov khoom tswj zoo sib xws. Piv txwv li, rau MM440 sib txawv - zaus tsav, koj tuaj yeem sau FB thaiv lub npe "MtrMM440." Hauv cov khoom-oriented programming, qhov no hu ua "chav kawm." Thaum koj xav tau kev tswj hwm kev tswj hwm rau lub cev muaj zog, koj tuaj yeem muab qhov keeb kwm yav dhau los DB thaiv rau nws -hauv cov khoom-kev taw qhia kev ua haujlwm, qhov no yog hu ua qhov kev siv ntawm chav kawm (ie, tsim ib qho piv txwv ntawm chav kawm: ib qho khoom). Thaum koj xav tau tswj ntau lub cev muaj zog, koj tuaj yeem muab cov keeb kwm sib txawv DBs rau qhov FB thaiv no, uas yog sib npaug rau kev tsim ntau yam ntawm cov chav kawm.
Kauj ruam 7 nta lwm hom kev pab cuam thaiv: FC thaiv. Programming feem ntau siv FC blocks raug xa mus rau raws li cov txheej txheem kev ua haujlwm hauv Siemens systems, uas tuaj yeem ua piv txwv rau cov txheej txheem kev ua haujlwm hauv computer programming- uas yog, programming uas ua haujlwm nkaus xwb -raws li.
Programming nrog Schneider's Unity software muab kev nkag siab zoo dua ntawm cov khoom -oriented programming. Nws cov ntsiab lus DFB suav nrog cov khoom siv nkag / tso tawm, cov khoom ntiag tug / pej xeem sib txawv, thiab kev siv cov lej- uas yog cov ntsiab lus tseem ceeb ntawm "chav kawm" hauv computer khoom-oriented programming. Tsim ib qho piv txwv ntawm chav kawm (ib yam khoom) yog qhov yooj yim li tsim ib qho "Boolean" hloov pauv tsis tu ncua; koj tsuas yog yuav tsum tau txhais qhov sib txawv ntawm qhov "chav kawm" no hauv "Function Blocks."
Ob Kauj Ruam 7 thiab Unity txhawb nqa ob qho tib si txheej txheem thiab cov khoom siv - cov txheej txheem kev taw qhia. Qhov sib txawv ntawm ob txoj hauv kev no zoo ib yam li qhov sib txawv ntawm kev ua haujlwm hauv C thiab C++ hauv siab - qib hauv computer hom lus.
Hauv cov lus piav qhia hauv qab no, FBs hauv Step7 thiab DFBs hauv Kev Sib Koom yuav raug hu ua "chav kawm," thaum kev sib txuas ntawm FB thiab keeb kwm yav dhau los DB hauv Kauj Ruam 7, nrog rau cov piv txwv ntawm DFBs hauv Kev Sib Koom, yuav raug xa mus rau "cov khoom."
II. Object-Oriented Programming Architecture
Cov kev sib tham saum toj no suav nrog cov ntsiab lus ntawm kev siv, tab sis lub tswv yim programming yog tsim los ntawm qhov kev pab cuam architecture. Tsuas yog siv cov khoom-txoj kev taw qhia hauv ib feem ntawm cov lej tsis txhais tau tias tag nrho cov kev pabcuam yog khoom siv- taw qhia. Hom programming no yuav tsum muaj txoj hauv kev raws li cov hauv qab no:

Nws ua raws li cov qauv ntawm daim duab ntaiv siv hauv kev tswj hwm relay, thiab cov neeg feem coob tuaj yeem kawm tau sai thiab paub nws. Nws tsuas yog cov lus programming nkaus xwb uas tau siv dav hauv kev siv tshuab automation rau ntau xyoo lawm, thiab nws yuav nyob twj ywm ib qho ntawm cov lus programming tseem ceeb hauv kev lag luam automation rau yav tom ntej.
Nyob rau tib lub sijhawm, raws li cov neeg los ntawm ntau haiv neeg thiab thaj chaw tau nkag mus rau hauv kev lag luam, ntau hom lus programming tau nkag mus rau hauv cov khoom siv automation. Cov no suav nrog kev ua haujlwm thaiv kev ua haujlwm, cov ntawv sau ua ke, lub xeev programming, thiab cov kab kos ua ntu zus. Plaub yam lus programming no, nrog rau cov ntaiv logic, tsim cov qauv programming lus txhais los ntawm International Electrotechnical Commission (IEC) tus qauv IEC 61131-3.
Lub logic tom qab IEC 61131 yog tias txhua tus neeg muag khoom ua raws li tus qauv no, tom qab ntawd - tsawg kawg rau qee qhov - ib tus neeg tsuas yog yuav tsum kawm tsib hom lus programming no kom yooj yim hloov ntawm cov platforms los ntawm cov neeg muag khoom sib txawv. Txawm li cas los xij, qhov no tsis yog li ntawd.
Tib yam siv rau cov kauj ruam yooj yim (xws li kev siv cov relay hu thiab coils); Txawm li cas los xij, thaum programming, ib tus yuav tsum kawm txhua tus neeg muag khoom cov syntax thiab cov neeg siv kev paub, nrog rau qhov tshwj xeeb ntawm kev siv lawv lub programming platform. Txawm hais tias tsis muaj kev tsim qauv, tus ntaiv logic muaj cov txiaj ntsig zoo hauv qab no ntawm cov khoom siv -kev ua haujlwm taw qhia:
