PLC nta

(1) Kev ntseeg siab. Txij li feem ntau PLCs siv ib leeg-chip microcomputers, lawv muaj kev sib koom ua ke. Tsis tas li ntawd, qhov sib thooj tiv thaiv circuits thiab kev kuaj xyuas tus kheej ua haujlwm txhim kho kev ntseeg tau ntawm lub system.
(2) Ib qho yooj yim programming. PLC programming feem ntau siv relay tswj ntaiv daim duab thiab cov lus txib, uas tsawg dua li cov lus qhia hauv microcomputer. Tsuas yog cov PLC nruab nrab thiab siab kawg, PLCs me me tsuas muaj txog 16 cov lus qhia. Txij li daim duab ntaiv yog vivid thiab yooj yim, nws yog ib qho yooj yim rau tus tswv thiab siv, thiab txawm tias tsis muaj kev txawj ntse hauv computer yuav tsum tau ua haujlwm.
(3) Yooj yim configuration. Txij li thaum PLC siv lub tsev thaiv cov qauv, cov neeg siv tsuas yog yuav tsum tau yooj yim sib txuas ua ke kom hloov pauv txoj haujlwm thiab qhov ntsuas ntawm qhov kev tswj hwm. Yog li ntawd, nws tuaj yeem siv rau txhua qhov kev tswj hwm.
(4) Ua kom tiav cov tswv yim / tso tawm muaj nuj nqi modules. Ib qho ntawm qhov zoo tshaj plaws ntawm PLC yog qhov sib txawv ntawm cov teeb liab (xws li DC lossis AC, hloov ntau, digital kom muaj nuj nqis lossis analog ntau, voltage lossis tam sim no, thiab lwm yam), muaj cov qauv sib xws uas tuaj yeem txuas ncaj qha rau cov khoom siv hauv teb. (xws li cov nyees khawm, keyboards, sensor 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 cov tshuab computer, kev teeb tsa ntawm PLC tsis tas yuav muaj chav tshuab tshwj xeeb lossis kev tiv thaiv nruj. Thaum siv, koj tsuas yog yuav tsum txuas cov cuab yeej tshawb nrhiav kom raug rau tus actuator thiab I / O interface davhlau ya nyob twg ntawm PLC ua haujlwm ib txwm.
(6) Kev khiav hauj lwm ceev ceev. Txij li kev tswj hwm ntawm PLC tau ua tiav los ntawm kev tswj hwm kev tswj hwm, nws txoj kev ntseeg siab thiab kev ua haujlwm ceev yog qhov sib piv rau kev tswj hwm kev tswj hwm.
Nyob rau hauv xyoo tas los no, kev siv cov microprocessors, tshwj xeeb tshaj yog nrog kev loj hlob ntawm ib leeg-chip microcomputers, tau txhim kho lub peev xwm ntawm PLCs thiab ua rau qhov sib txawv ntawm PLCs thiab microcomputer tswj cov tshuab me me, tshwj xeeb tshaj yog rau high-end PLCs.
