PLC yog vim li cas rau kev loj hlob sai, muaj ntau yam tshwj xeeb cov kev txhawb nqa kev muaj tshuab, kev nyab xeeb, yooj yim, yooj yim thiab kev lag luam, lwm yam, nws cov yam ntxwv tseem ceeb yog raws li hauv qab no.
1. Kev cuam tshuam los tiv thaiv kev cuam tshuam, muaj kev ntseeg siab
Nyob rau hauv ib txwm muaj kev tswj hwm kev tswj hwm, kev siv ntau ntawm cov khoom siv sib txuas lus nruab nrab, vim tias muaj kev sib tiv thaiv kev ua haujlwm, vim muaj kev sib tiv tauj zoo, txo qis kev ntseeg tau ntawm lub system Cov. Hauv Plc tswj cov tshuab muaj ntau tus ntawm kev hloov pauv tau ua tiav los ntawm kev tiv toj los ntawm kev sib cuag los ntawm kev sib cuag los ntawm kev sib tw semiconductor zoo, thiaj li swb tau zoo heev.
Ib qho ntxiv, kev ntsuas tau raug coj los ntawm cov khoom kho vajtse thiab software ntawm lub plc los txhim kho nws txoj kev ntseeg tau. Ntawm cov khoom kho vajtse, txhua tus IO cuam tshuam yog optically raug cais tawm, ua kom nws lub cev sib cais sab nraud hluav taws xob sab nraud ntawm PLC's sab hauv circuits. Kev tiv thaiv kev ntsuas yog siv hauv txhua tus qauv los tiv thaiv kev cuam tshuam hluav taws xob. Kev lim dej siv tshuab yog siv nyob rau hauv Circuit Court kom tiv thaiv lossis tiv thaiv kev cuam tshuam high-zaus. Nyob rau hauv cov nqe lus ntawm software, plC muaj qhov kev ntsuas tus kheej zoo, ib zaug kho vajtse thiab cov ntaub ntawv CPU yuav tshwm sim los tiv thaiv qhov tsis ua haujlwm ntawm kev nthuav dav. Feem ntau PLC muaj lub watchdog muaj nuj nqi.
Rau cov phiaj xwm loj plc, koj kuj tuaj yeem siv dual-CPU redundant system lossis peb-CPU kev xaiv tsa, yog li kev ntseeg tau ntawm cov kab ke tau zoo ntxiv.
2. Yooj yim thiab yooj yim rau kev kawm cov program, lub kaw lus tsim qauv thiab debugging ncig yog luv
PLC yog cov cuab yeej siv cov neeg siv khoom siv, cov qauv plc coj mus rau hauv cov cuab yeej ntawm cov kws tshaj lij, cov duab ntaiv tuaj yeem siv lossis cov lus qhia yooj yim rau cov qauv tswj khoom lag luam. Diav dej kos duab thiab relay schematic daim duab yog zoo heev, intuitive, yooj yim kom paub cov kev paub tshwj xeeb thiab kev paub tshwj xeeb. Cov neeg tsim qauv tuaj yeem tsim qauv, hloov thiab simulate qhov kev zam debugging hauv chav tsim, yooj yim heev.
3. Yooj yim installation, txij nkawm yooj yim
PlC tsis xav tau lub tshuab tshwj xeeb, tuaj yeem khiav ncaj qha rau hauv ib puag ncig muaj kev lag luam thiab PLC tau txuas nrog IO Terminal, tuaj yeem muab tso rau hauv kev ua haujlwm. Ntau cov qauv muaj kev ua haujlwm thiab kev ua txhaum kev ntsuas, uas yooj yim rau cov neeg siv kom nkag siab txog qhov xwm txheej ua haujlwm thiab pom kev ua txhaum.
4. Txais modularized qauv, cov ntim me me thiab lub teeb hnyav.
Txhawm rau yoog kom haum rau cov kev xav tau ntawm kev tswj hwm PLC, feem ntau cov qauv plc, muab cov hluav taws xob ntau thiab rau cov qauv, thiab lwm yam. Tsis tas li ntawd, PLC yog ntau me me nyob rau hauv loj thiab qhov hnyav piv rau General-hom phiaj muaj tshuab tswj lub tshuab.
5. Nplua IO interface module, muaj zog nthuav dav muaj zog
PlC rau cov paib muaj kev sib txawv (xws li AC lossis DC, hloov lossis muaj zog lossis muaj zog lossis cov khoom siv (xws li cov nyees khawm, hloov chaw, Qhov sib thooj, sensors thiab transmitters, solenoid coils thiab tswj cov li qub, thiab lwm yam) txuas ntxiv txuas. Tsis tas li ntawd, txhawm rau txhim kho kev ua haujlwm ua haujlwm, nws muaj ntau yam tib neeg-tshuab dialog interface module; Txhawm rau ua ib qho chaw muaj kev lag luam hauv zos, muaj ntau yam kev sib txuas lus sib txuas lus interface module.
