PLC yog dab tsi?
PLC yog lub npe luv ntawm Programmable Logic Controller.
Programmable logic maub los yog lub lag luam digital hluav taws xob tsim tshwj xeeb rau kev siv hauv ib puag ncig kev lag luam.Nws txais ib hom programmable nco, uas khaws cov lus qhia ua haujlwm logic, tswj kev sib lawv liag, sijhawm, suav thiab lej lej, thiab tswj ntau hom kev ua haujlwm.cov cuab yeej siv tshuablos yog txheej txheem ntau lawm los ntawm digital lossis analog input thiab tso zis.
Cov yam ntxwv ntawm PLC
1.Kev ntseeg siab
Vim tias PLC feem ntau siv ib leeg-chip microcomputer, nws muaj kev sib koom ua ke siab, ua ke nrog cov kev tiv thaiv sib txuas thiab kev kuaj xyuas tus kheej, uas txhim kho kev ntseeg tau ntawm lub cev.
2. Yooj yim programming
Qhov kev zov me nyuam ntawm PLC feem ntau txais yuav relay tswj ntaiv daim duab thiab cov lus txib, thiab nws cov lej tsawg dua li ntawm microcomputer. Ntxiv rau qhov nruab nrab thiab qib siab PLCs, tsuas muaj li ntawm 16 lub PLC me me feem ntau. Vim hais tias daim duab ntaiv yog vivid thiab yooj yim, nws yog ib qho yooj yim rau tus tswv thiab siv. Nws tuaj yeem raug programmed yam tsis muaj kev paub txog computer.
3.Yooj yim configuration
Txij li thaum PLC tau txais lub tsev thaiv cov qauv, cov neeg siv tuaj yeem hloov pauv qhov kev ua haujlwm thiab qhov ntsuas ntawm qhov kev tswj hwm los ntawm kev sib txuas ua ke. Yog li ntawd, nws tuaj yeem siv rau txhua qhov kev tswj hwm.
4.Ua kom tiav input / output function modules
Ib qho txiaj ntsig zoo tshaj plaws ntawm PLC yog qhov sib txawv ntawm cov teeb liab (xws li DC lossis AC, hloov tus nqi, digital lossis analog nqi, voltage lossis tam sim no, thiab lwm yam), muaj cov qauv sib xws, uas tuaj yeem txuas ncaj qha nrog cov khoom siv hauv teb. (xws li cov nyees khawm, keyboards, sensing tam sim no transmitters, lub cev muaj zog pib lossis tswj li qub, thiab lwm yam) thiab txuas nrog CPU motherboard los ntawm lub tsheb npav.
5.Ib qho yooj yim installation
Piv nrog rau lub khoos phis tawj, kev teeb tsa ntawm PLC tsis tas yuav muaj chav tshwj xeeb hauv computer lossis kev tiv thaiv nruj. Thaum siv, nws tuaj yeem ua haujlwm ib txwm tsuas yog los ntawm kev txuas cov cuab yeej tshawb nrhiav kom raug nrog I / O interface davhlau ya nyob twg ntawm tus actuator thiab PLC.
6.Kev khiav ceev ceev
Vim tias kev tswj hwm ntawm PLC tau ua tiav los ntawm kev tswj hwm kev tswj hwm, nws txoj kev ntseeg siab thiab kev khiav ceev yog qhov tsis sib xws los ntawm kev tswj xyuas cov logic relay. Nyob rau hauv xyoo tas los no, kev siv cov microprocessors, tshwj xeeb tshaj yog nrog coob tus ib nti microcomputer, tau zoo heev txhim kho lub peev xwm ntawm PLC, thiab ua rau qhov sib txawv ntawm PLC thiab microcomputer tswj system me me, tshwj xeeb tshaj yog qib siab PLC.
Raws li koj tuaj yeem pom hauv daim vis dis aus, kev sib xyaw tshuab, pneumatic thiab hluav taws xob, txhua qhov kev ua haujlwm yog tswj los ntawm PLC. Kov npo ua rau kev ua haujlwm yooj yim thiab yooj yim. Raws li GTMSMART Tshuab, peb tsis tu ncua tsim peb cov khoom nrog cov cuab yeej tshiab thiab muab kev ua haujlwm siabyas thermoforming tshuabuas yuav txaus siab rau peb cov neeg siv khoom.
