Izinto ezilungileyo zenkqubo ye-PLC enomatshini wokupakisha

Kwakukho ixesha apho inkqubo ye-PLC yayingeyonxalenye yomatshini wokupakisha, njengomatshini wokutywina owenziwe ngesandla. Ngenxa yoko, kwakufuneka abasebenzi abongezelelekileyo ukuqinisekisa ukuba umsebenzi uyenziwa. Nangona kunjalo, umphumo wawudanisa. Inkcitho yexesha nemali yayininzi.

Nangona kunjalo, konke kwatshintsha ngokufika kweenkqubo ze-PLC ezifakwe ngaphakathi kumatshini wokupakisha.

Ngoku, iinkqubo ezininzi ezizenzekelayo zinokusebenza kunye ngokufanelekileyo. Ungasebenzisa inkqubo ye-PLC ukulinganisa ngokuchanekileyo iimveliso, uze uzipakishele ukuthunyelwa. Ukongeza, oomatshini banesikrini solawulo se-PLC apho unokutshintsha oku kulandelayo:

· Ubude bebhegi

· Isantya

· Iingxowa zamakhonkco

· Ulwimi kunye neKhowudi

· Ubushushu

· Okuninzi ngakumbi

Ikhulula abantu kwaye yenza yonke into ibe lula kwaye iqonde ukuba bayisebenzise.

Ukongeza, ii-PLCs zakhiwe ukuze zihlale, ukuze zikwazi ukunyamezela iimeko ezinzima, kubandakanya ukushisa okuphezulu, umbane ovuthayo, umoya omanzi, kunye nokushukuma. Abalawuli be-Logic abafani nezinye iikhomputha kuba zibonelela ngegalelo / imveliso enkulu (I / O) yokulawula kunye nokubeka iliso kwii-actuator ezininzi kunye ne-sensor.

Inkqubo ye-PLC izisa nezinye izibonelelo ezininzi kumatshini wokupakisha. Ezinye zazo zezi:

Ukusebenziseka lula

Umcwangcisi wekhompyuter oyingcali akufuneki ukuba abhale ikhowudi ye-PLC. Yenziwe ukuba ibe lula, kwaye ungayilawula kwiiveki ezimbalwa. Kungenxa yokuba isebenzisa:

· I-relay control ladder diagrams

· imiyalelo yomyalelo

Okokugqibela, imizobo ileli iyaqondakala kwaye iqonde ukuyiqonda kwaye isetyenziswe ngenxa yobume bayo bokubonwayo.

Ukusebenza ngokuthe gqolo

Ii-PLCs zisebenzisa ii-microcomputers ze-single-chip, zizenza zidityaniswe kakhulu, kunye nesekethe yokhuseleko ehambelanayo kunye nemisebenzi yokuzixilonga eyandisa ukuthembeka kwenkqubo.

Ukufakela kulula

Ngokuchaseneyo nenkqubo yekhompyuter, ukuseta i-PLC akufuni gumbi lekhompyuter elizinikeleyo okanye izilumkiso ezinzima zokhuseleko.

Ukonyusa isantya

Ekubeni ulawulo lwe-PLC luphunyezwa ngolawulo lweprogram, alunakuthelekiswa nolawulo lwengqiqo yokubuyisela malunga nokuxhomekeka okanye isantya sokusebenza. Ke, inkqubo ye-PLC iya konyusa isantya somatshini wakho usebenzisa igalelo elibukhali, elinengqiqo.

Isisombululo esisezantsi

Iinkqubo ezisekelwe kwi-Relay-logic, ezazisetyenziswa kwixesha elidlulileyo, zibiza kakhulu ngokuhamba kwexesha. Izilawuli zengqiqo ezicwangcisiweyo zaphuhliswa njengokutshintshwa kweenkqubo zolawulo ezisekelwe kwi-relay.

Iindleko ze-PLC zifana notyalo-mali lwexesha elinye, kwaye ukonga kwiinkqubo ezisekelwe kwi-relay-based, ngakumbi malunga nexesha lokusombulula ingxaki, iiyure zobunjineli, kunye neendleko zokufakela kunye nokugcinwa, zininzi.

Ubudlelwane beenkqubo ze-PLC kunye neshishini lokupakisha
