Nyob rau hauv lub ntiaj teb no ntawm kev tsim thiab cuab yeej, automation yog tus yuam sij rau kev txhim kho efficiency, txo qhov yuam kev, thiab boosting productivity. Lub Programmable Logic Controller (PLC) yog lub hlwb ntawm feem ntau automation systems, thiab thaum nws los txog rau txhim khu kev qha thiab siab -PLCs ua tau zoo, Siemens PLC yog ib qho kev xaiv saum toj kawg nkaus. Tab sis nrog ntau Siemens PLC qauv muaj, koj yuav xaiv qhov zoo li cas rau koj qhov kev tsim khoom tshwj xeeb thiab cov cuab yeej siv? Phau ntawv qhia no yuav qhia koj txog cov kauj ruam tseem ceeb, cov kev xav tseem ceeb, thiab cov lus qhia siv tau los txiav txim siab paub. Txawm hais tias koj tab tom ua haujlwm ntawm cov cuab yeej me me lossis loj- cov kab tsim khoom loj, txoj cai Siemens PLC tuaj yeem ua rau txhua qhov sib txawv hauv koj qhov kev ua tiav.
1. Pib nrog nthuav qhia koj qhov kev tsim khoom thiab cov cuab yeej ua haujlwm xav tau
Ua ntej koj pib tshawb xyuas cov qauv sib txawv Siemens PLC, thawj kauj ruam thiab tseem ceeb tshaj plaws yog kom paub meej tias koj qhov project xav tau. Txhua qhov kev tsim khoom thiab cov cuab yeej cuab yeej yog qhov tshwj xeeb, thiab koj qhov kev xaiv PLC yuav tsum ua raws li nws cov kev xav tau tshwj xeeb. Nov yog ob qho tseem ceeb uas yuav tsum tsom mus rau:
1.1 Txheeb xyuas qhov project Scale thiab Workload
Qhov loj ntawm koj qhov project ncaj qha cuam tshuam rau hom Siemens PLC koj xav tau. Rau cov phiaj xwm me me, xws li ib lub tshuab cuab yeej lossis lub chaw nres tsheb me me, lub compact Siemens PLC yuav ntau tshaj qhov txaus. Cov qauv no yog tus nqi - zoo, yooj yim rau nruab, thiab tsis tas yuav tsum muaj ntau qhov chaw. Ntawm qhov tod tes, loj- nplai tsim cov haujlwm, zoo li tag nrho cov kab ntau lawm nrog ntau lub tshuab thiab cov txheej txheem nyuaj, xav tau ib qho modular Siemens PLC uas tuaj yeem ua haujlwm hnyav, txhawb ntau cov tswv yim / tawm (I / O) cov ntsiab lus, thiab koom nrog ntau lub tshuab. Piv txwv li, yog tias koj tab tom khiav lub khw muag khoom me me, Siemens S7-1200 (tus qauv nrov compact) tej zaum yuav zoo tagnrho. Tab sis rau cov khoom siv hluav taws xob loj loj, Siemens S7-1500 (tus qauv qauv, kev ua haujlwm siab) yuav zoo dua. Cov kauj ruam no yuav pab koj txo qis koj cov kev xaiv thiab tsis txhob siv nyiaj ntau dhau ntawm Siemens PLC uas muaj zog heev rau koj cov kev xav tau, lossis xaiv tus qauv yooj yim uas tsis tuaj yeem ua raws li koj qhov project txoj haujlwm.
1.2 Txheeb xyuas cov haujlwm tsim nyog thiab cov yam ntxwv
Tom ntej no, sau tawm cov haujlwm tshwj xeeb uas koj qhov project xav kom Siemens PLC ua. Koj puas xav tau nws los tswj kev ua haujlwm yooj yim rau / tawm, lossis tswj kev tswj cov lus tsa suab kom meej? Nws puas yuav xav tau kev sib txuas lus nrog lwm yam khoom siv, xws li cov sensors, HMIs (Tib neeg-Tsev interfaces), lossis huab- raws li kev soj ntsuam xyuas? Piv txwv li, yog tias koj qhov kev siv cuab yeej cuam tshuam nrog kev txiav los yog kev tsim cov ntaub ntawv, koj yuav xav tau Siemens PLC nrog lub peev xwm tswj tau. Yog tias koj xav taug qab cov ntaub ntawv tsim tawm tiag tiag - lub sijhawm, nrhiav tus qauv uas txhawb nqa kev sib txuas lus hauv kev lag luam xws li PROFINET. Tsis tas li, xav txog kev nthuav dav yav tom ntej: yog tias koj npaj yuav ntsuas koj qhov kev tsim khoom lossis kev ua haujlwm tom qab, xaiv Siemens PLC uas tuaj yeem hloov kho tau yooj yim nrog cov qauv ntxiv. Qhov no yog qhov uas nkag siab qhov sib txawv ntawm qhov yooj yim thiab qib siab Siemens PLC cov yam ntxwv dhau los ua qhov tseem ceeb heev -tsis txhob them rau cov yam ntxwv uas koj yuav tsis siv, tab sis tsis txhob skimp rau cov uas tseem ceeb rau koj qhov kev xav tau tam sim no thiab yav tom ntej.
2. Paub koj tus kheej nrog Common Siemens PLC Series
Siemens muaj ntau lub PLC series tsim los rau ntau daim ntawv thov, los ntawm me me - teev cov cuab yeej mus rau kev lag luam loj. Paub txog cov yam ntxwv tseem ceeb ntawm txhua series yuav pab koj sib phim lawv rau koj qhov project xav tau. Cia peb saib ze dua ntawm cov neeg nyiam tshaj plaws:

Ib qho tseem ceeb tshaj plaws yog compatibility. Koj lub Siemens PLC tshiab yuav tsum ua haujlwm tsis tu ncua nrog koj cov cuab yeej tsim khoom, sensors, HMIs, thiab lwm yam khoom siv automation. Piv txwv li, yog tias koj twb tau siv Siemens HMIs lossis tsav, xaiv Siemens PLC los ntawm tib tsev neeg cov khoom (xws li S7-1200 lossis S7-1500) yuav ua kom muaj kev sib koom ua ke. Yog tias koj muaj cov cuab yeej thib peb, xyuas seb Siemens PLC txhawb cov kev sib txuas lus tsim nyog (xws li PROFINET, Modbus, lossis Ethernet/IP). Qhov no yog qhov uas lub tswv yim ntawm Siemens PLC kev sib raug zoo nrog cov cuab yeej tsim khoom los rau hauv kev ua si-tsis zoo sib xws tuaj yeem ua rau qeeb, nce nqi, thiab txo kev ua haujlwm. Nco ntsoov txheeb xyuas qhov sib haum ua ntej ua kev yuav khoom.
3.2 Kev txiav txim siab nqi thiab nyiaj txiag
Tus nqi yog qhov tseem ceeb rau feem ntau cov haujlwm, tab sis nws yog ib qho tseem ceeb kom sib npaug tus nqi nrog kev ua haujlwm. Thaum lub compact Siemens PLC zoo li lub LOGO! 8 lossis S7-1200 yog pheej yig dua, nws yuav tsis txaus rau cov haujlwm nyuaj. Ntawm qhov tod tes, qhov siab -kawg S7-1500 tej zaum yuav dhau mus ua haujlwm me me. Xav txog tsis yog thawj tus nqi yuav khoom xwb, tab sis kuj yog cov nqi mus sij hawm ntev xws li kev saib xyuas, khoom seem, thiab daim ntawv tso cai software. Yog tias koj tab tom nrhiav nyiaj txiag nruj, nrhiav Siemens PLC uas pheej yig rau cov cuab yeej siv me me uas tseem ua tau raws li koj qhov yuav tsum tau ua. Nco ntsoov, kev nqis peev hauv txoj cai Siemens PLC tam sim no tuaj yeem txuag koj cov nyiaj hauv lub sijhawm ntev los ntawm kev txo qis qis thiab txhim kho kev ua haujlwm.
3.3 Technical Support thiab Reliability
Siemens paub txog nws cov khoom txhim khu kev qha, tab sis nws tseem ceeb heev uas yuav tsum xav txog qhov muaj kev txhawb nqa. Xaiv Siemens PLC qauv uas muaj kev txhawb nqa zoo hauv koj cheeb tsam- qhov no yuav ua rau nws yooj yim dua kom tau txais kev pab yog tias koj ntsib teeb meem nrog kev ua haujlwm, kev teeb tsa, lossis kev saib xyuas. Siemens muaj cov kev pabcuam dav dav, suav nrog cov neeg siv phau ntawv, kev qhia online, thiab thoob ntiaj teb kev sib koom tes ntawm kev pabcuam. Tsis tas li ntawd, xav txog kev ntseeg siab ntawm Siemens PLC hauv koj qhov chaw ua haujlwm tshwj xeeb. Yog tias koj qhov kev tsim khoom lossis cov cuab yeej ua haujlwm ua haujlwm hauv cov plua plav, av noo, lossis siab - qhov kub thiab txias, xaiv tus qauv tsim los tiv thaiv cov xwm txheej no (saib IP ntsuas qhov tshwj xeeb). Lub Siemens PLC txhim khu kev qha yuav txo qis qis qis thiab ua kom koj qhov project ua haujlwm zoo.
3.4 Yooj yim ntawm Programming thiab Kho
Rau ntau pab pawg tsim khoom thiab cuab yeej, kev yooj yim ntawm kev ua haujlwm thiab kev saib xyuas yog qhov tseem ceeb rau kev txiav txim siab. Siemens PLCs siv TIA Portal (Tag nrho Integrated Automation Portal) software rau programming, uas yog tus neeg siv - tus phooj ywg thiab muaj ib qho chaw sib koom ua ke rau kev teeb tsa, kev ua haujlwm, thiab kev sim. Txawm li cas los xij, qee cov qauv zoo tshaj plaws yuav xav tau kev txawj tshwj xeeb tshaj plaws. Yog tias koj pab neeg tau txwv PLC programming kev paub, xaiv tus qauv uas yooj yim rau kev ua haujlwm nrog, xws li S7-1200 lossis LOGO! 8. Tsis tas li ntawd, nrhiav Siemens PLC cov qauv uas yooj yim - mus rau - cov khoom siv thiab cov ntaub ntawv meej-qhov no yuav ua kom yooj yim rau kev saib xyuas thiab txo lub sij hawm xav tau los daws teeb meem.
4. Kauj Ruam -los ntawm - Kauj Ruam Kev Xaiv Cov Siemens PLC
Txhawm rau xaus, ntawm no yog cov kauj ruam yooj yim -los ntawm - cov kauj ruam xyuas los pab koj xaiv Siemens PLC txoj cai rau koj qhov kev tsim khoom thiab cov cuab yeej siv:
