1. Main hloov
Lub ntsiab hloov pauv yog lub hwj chim tswj ntawm tag nrho cov txee. Raws li qhov tam sim no, koj tuaj yeem xaiv qhov hloov pauv huab cua xws li lub tshuab hluav taws xob me me. Feem ntau hais lus, tsis tsuas yog PLC hluav taws xob tswj cov txee muaj qhov hloov pauv, tab sis lwm cov khoom ua tiav kuj tseem muaj qhov hloov pauv tseem ceeb.
2. PLC
Qhov no yog lub hauv paus. Tus nqi ntawm PLC hluav taws xob tswj cov khoom nyob hauv qhov no, thiab tus nqi siab kuj tseem kim vim yog cov khoom siv no. PLC yuav tsum raug xaiv raws li qhov xav tau ntawm qhov project. Piv txwv li, yog tias qhov project me me, nws tuaj yeem ncaj qha rau kev sib koom ua ke PLC, tab sis yog tias qhov project loj heev, nws yuav xav tau ib qho module lossis daim npav hom, thiab kuj tseem yuav xav tau redundancy (uas yog, ob txheej ntawm kev sib hloov siv).
3. Fais fab mov
24VDC hloov fais fab mov. Feem ntau PLCs tuaj nrog 24VDC fais fab mov. Ntawm chav kawm, seb puas yuav siv qhov kev hloov hluav taws xob no nyob ntawm seb nws puas xav tau tiag tiag.
4. Relay
Feem ntau, PLC tuaj yeem xa cov lus qhia ncaj qha mus rau lub voj voog tswj, tab sis nws kuj tseem yuav raug xa mus los ntawm kev xa rov qab ua ntej. Piv txwv li, yog tias qhov chaw nres nkoj tso zis ntawm koj lub PLC yog siv los ntawm 24VDC, tab sis cov node uas yuav tsum tau muab los ntawm PLC hauv daim duab ntawm koj lub voj voog tswj yog 220VAC, ces koj yuav tsum ntxiv ib qho relay rau qhov chaw nres nkoj ntawm PLC, uas yog, tus relay yuav ua thaum cov lus txib raug muab, thiab tom qab ntawd txuas cov node ntawm lub voj voog tswj mus rau qhov nquag qhib lossis ib txwm kaw ntawm lub relay. Nws kuj yog nyob ntawm qhov xwm txheej tiag tiag los xaiv seb puas siv lub relay.
5. Terminal blocks
Qhov no yog qhov tseem ceeb tshaj plaws rau txhua lub txee, thiab nws tuaj yeem teeb tsa raws li tus naj npawb ntawm cov teeb liab.
Yog tias nws tsuas yog ib qho yooj yim PLC tswj txee, qhov yooj yim cov no txaus. Yog tias koj xav tau lwm yam hauv koj lub txee tswj, koj tuaj yeem nce lawv raws li qhov xwm txheej. Piv txwv li, tej zaum koj yuav xav tau lub zog rau qee cov twj paj nruag ntawm qhov chaw lossis cov thawv me me, yog li koj yuav tsum tau nce cov cua hloov pauv. Lossis yog tias koj xav kom PLC txuas nrog lub khoos phis tawj tswj hwm, koj yuav tsum tau ntxiv qhov hloov pauv lossis qee yam. Nws nyob ntawm qhov xwm txheej tshwj xeeb. Cov kev teeb tsa sib txawv nyob ntawm lub zog ib puag ncig thiab cov kev xav tau, tab sis cov saum toj no yog cov khoom tseem ceeb ntawm PLC hluav taws xob tswj txee.
