Tom qab ntawd, lo lus nug yog, dab tsi yog qhov pib ntawm PLC? Basic PLC kev ua haujlwm. Cov yooj yim element of ib PLC suav nrog cov input modules lossis cov ntsiab lus, Central ProcessingUnit (CPU), tso zis modules lossis cov ntsiab lus, thiab cov khoom siv programming. Output modules hloov cov cim tswj los ntawm CPU rau hauv cov txiaj ntsig digital oranalog uas tuaj yeem siv los tswj ntau yam khoom siv.
Ib sab saum toj no, muaj pes tsawg hom PLC programming muaj?
Feem ntau ntawm PLC Cov txheej txheem niaj hnub no ua raws li IEC 61131/3 tswj tshuab programming Tus qauv uas txhais tau 5 yam lus: Ladder Diagram (LD), Structured Text (ST), Function Block Diagram (FBD), Instruction List (IL) thiab sequentialfunction chart (SFC).
Hom maub los twg yog siv hauv PLC?
A PLC yog lub hom phiaj dav dav tus tswj . Ntawm no yog siv nyob rau hauv mechanized automation, tab sis nws dav heev nyob rau hauv daim ntawv thov. PID feem ntau yog hais txog ib daim ntawv kaw-loopcontrol; npe rau cov ntsiab lus Proportional, Integral thiab Derivative. PID cov tswj feem ntau siv hauv qhov kub thiab txias.
