Yini i-PLC?
PLC sifinyeto se Umlawuli Logic Lohlelwako.
Umlawuli we-logic lohlelekile luhlelo lwe-elekthronikhi lwekusebenta kwedijithali lolwentelwe ngalokukhetsekile kusetjentiswa endzaweni yetimboni.Itsatsa luhlobo lwememori lehlelekako, legcina ticondziso tekwenta umsebenti lonengcondvo, kulawula kulandzelana, sikhatsi, kubala kanye nekusebenta kwetibalo, futsi ilawula tinhlobo letehlukahlukene te . imishini yekusebenta noma inchubo yekukhicita ngekufaka kanye nekukhipha kwedijithali noma kwe-analog.
Timphawu te-PLC
1.Kwetsembeka lokusezingeni leliphakeme
Ngoba PLC kakhulu wamukela microcomputer single-chip, has kuhlanganiswa eliphezulu, kuhambisana imijikeleto ehambisanayo ukuvikela kanye self-kuhlola imisebenti, okuyinto ngcono kwetsembeka uhlelo.
2. Kuhlela lokulula
Lokuhlelwa kwe-PLC kakhulu kwemukela umdvwebo weliladi lekulawula relay kanye nesitatimende semyalo, futsi inombolo yayo ingaphansi kakhulu kunaleyo ye-microcomputer. Ngetulu kwema-PLC lasemkhatsini nalasesigabeni lesiphakeme, kunema-PLC lamancane langaba ngu-16 kuphela jikelele. Ngenca yekutsi lomdvwebo weliladi ucacile futsi ulula, kulula kuwufundza kahle futsi uwusebentise. Ingahlelwa ngaphandle kwelwati lwebungcweti bekhompyutha.
3.Kuhleleka lokugucugucukako
Njengobe i-PLC yamukela isakhiwo sekwakha, basebentisi bangashintja ngekugucugucuka umsebenti kanye nesikali seluhlelo lwekulawula ngekutsi nje babahlanganise. Ngako-ke, ingasetjentiswa kunobe nguyiphi indlela yekulawula.
4.Gcwalisa emamojuli emsebenti wekufaka / wekukhipha
Lomunye wetinzuzo letinkhulu kakhulu PLC kutsi for timphawu letehlukene ensimini (njenge DC noma AC, inani lokushintja, inani ledijithali noma analog, voltage noma lamanje, njll.), kukhona tifanekiso letihambisanako, letingaxhunywa ngqo amadivayisi ensimu yetimboni (njengetinkinobho, switches, sensing valves zamanje transmitters mo, motor C). libhasi.
5.Kulula kufaka
Nawucatsanisa neluhlelo lwekhompyutha, kufakwa kwe-PLC akudzingi igumbi lelikhetsekile lekhompyutha nobe tindlela leticinile tekuvikela. Uma kusetjentiswa, kungasebenta evamile kuphela ngekuxhuma kahle idivayisi kutfola nge I / O interface terminal actuator kanye PLC.
6.Sivinini lesisheshako sekugijima
Ngoba kulawulwa kwe-PLC kwentiwa ngekulawula luhlelo, kwetsembeka kwayo kanye nesivinini sekugijima akulinganiswa nekulawula kwe-relay logic. Eminyakeni yamuva, kusetjentiswa kwema-microprocessors, ikakhulukati ngenani lelikhulu le-microcomputer le-chip yinye, kwenta umehluko emkhatsini we-PLC kanye neluhlelo lwekulawula ema-microcomputer ube mncane futsi ube mncane, ikakhulukati i-PLC lesesigabeni lesiphakeme.
Njengobe ungabona kule-video, inhlanganisela yemishini, yemoya kanye negezi, tonkhe tento tekusebenta tilawulwa yi-PLC. Sikrini sekutsintsa senta umsebenti ube lula futsi ube lula. Njenge-GTMSMART Machine, siyachubeka nekutfutfukisa imikhicito yetfu ngebuchwepheshe bamuva futsi siniketa kusebenta kahle lokusezingeni leliphakeme . umshini wekushisa wepulasitiki lokutawenetisa emakhasimende etfu.
