I-Programmable Logic Controller (PLC) yinkqubo ye-elektroniki yokusebenza kwedijithali eyenzelwe ngokukodwa usetyenziso kwiindawo zoshishino.Isebenzisa inkumbulo ecwangcisiweyo ukugcina imiyalelo yokwenza imisebenzi yengqiqo, ulawulo olulandelelanayo, ixesha, ukubala, kunye nokusebenza kwezibalo ngaphakathi kuyo.Ilawula iintlobo ezahlukeneyo zezixhobo zoomatshini okanye iinkqubo zokuvelisa ngokusebenzisa i-digital okanye i-analog input kunye nemveliso.
I-Programmable Logic Controller (PLC) isilawuli se-arithmetic yedijithali kunye ne-microprocessor yokulawula ngokuzenzekelayo, enokugcina kwaye iqhube imiyalelo yokulawula kwimemori yomntu nangaliphi na ixesha.Umlawuli ocwangcisiweyo uqulunqwe ziiyunithi ezisebenzayo ezifana ne-CPU, umyalelo kunye nememori yedatha, igalelo / i-interface yemveliso, ukunikezelwa kwamandla, ukuguqulwa kwedijithali ukuya kwi-analog, njl. Kwiintsuku zokuqala, abalawuli beengcamango ezicwangcisiweyo babenomsebenzi wokulawula ingqiqo, ngoko ke. babizwa ngokuba ngabalawuli beengqiqo ezicwangcisekileyo.Kamva, ngophuhliso oluqhubekayo, ezi modyuli zekhompyutha kunye nemisebenzi elula ekuqaleni yayinemisebenzi eyahlukeneyo, kubandakanywa nokulawula ingqiqo, ulawulo lwexesha, ulawulo lwe-analog, kunye nokunxibelelana koomatshini abaninzi.Eli gama likwatshintshwa laba nguMlawuli oHlengahlelekayo, nangona kunjalo, ngenxa yongquzulwano phakathi kwesishunqulelo sePC kunye nesishunqulelo seKhompyutha yoBuqu, kwaye ngenxa yezizathu zesintu, abantu basasebenzisa igama elithi isilawuli sengqiqo ecwangcisiweyo, kwaye basasebenzisa isishunqulelo se-PLC.Undoqo wesilawuli se-PLC esicwangcisiweyo yikhompyuter ezinikele kulawulo lwamashishini.Amacandelo ayo asisiseko abandakanya: imodyuli yombane, imodyuli ye-CPU, imemori, i-I / O imodyuli yokufaka kunye nemveliso, i-backplane kunye nemodyuli ye-rack, imodyuli yonxibelelwano, imodyuli esebenzayo, njl.
I-PLC iProgrammable Logic Controller: I-PLC yaziwa ngokupheleleyo njengoMlawuli weNgcaciso oHlelekileyo ngesiNgesi kunye nesilawuli esinocwangco esiseTshayina.Ichazwa njengenkqubo yombane eqhutywa yimisebenzi yedijithali, eyenzelwe ngokukodwa ukusetyenziswa kwiindawo zoshishino.Isebenzisa iklasi yememori ecwangcisiweyo yokugcina iinkqubo ngaphakathi, ukwenza imiyalelo ejoliswe ngumsebenzisi efana nokusebenza okunengqiqo, ukulawula ngokulandelelana, ixesha, ukubala, kunye nokusebenza kwe-arithmetic, kunye nokulawula iintlobo ezahlukeneyo zeenkqubo zoomatshini okanye zokuvelisa ngokusebenzisa i-digital okanye i-analog input / output.I-DCS yeNkqubo yoLawulo loSasazo: Igama elipheleleyo lesiNgesi le-DCS yiNkqubo yoLawulo loSasazo, ngelixa igama elipheleleyo lesiTshayina liyiNdlela yoLawulo loSasazo.I-DCS inokutolikwa njengemveliso ye-automated high-tech esetyenziswa ngokubanzi kumashishini apho kukho ulawulo oluninzi lwe-analog loop, ukunciphisa umngcipheko obangelwa kulawulo, kunye nolawulo oluphakathi kunye nemisebenzi yokubonisa.I-DCS ngokubanzi inamacandelo amahlanu: 1: umlawuli 2: I/O ibhodi 3: isikhululo sokusebenza 4: inethiwekhi yonxibelelwano 5: imizobo kunye nesoftware yenkqubo.
1. Imodyuli yamandla, enika amandla angaphakathi okusebenza kwi-PLC yokusebenza, kwaye abanye banokubonelela ngamandla kwiimpawu zokufaka.
2. Imodyuli ye-CPU, eyona yunithi yokucubungula ephakathi ye-PLC, ingundoqo ye-PLC hardware.Ukusebenza okuphambili kwe-PLC, njengesantya kunye nesikali, kubonakaliswa ngokusebenza kwayo;
3. Imemori: Igcina kakhulu iinkqubo zabasebenzisi, kwaye ezinye zibonelela ngememori eyongezelelweyo yokusebenza kwisistim.Ngokwesakhiwo, imemori iqhotyoshelwe kwimodyuli ye-CPU;
4. Imodyuli ye-I / O, edibanisa iisekethe ze-I / O kwaye ihlukaniswe kwiimodyuli zenkcazo eyahlukeneyo ngokwenani lamanqaku kunye nohlobo lwesekethe, kuquka i-DI, DO, AI, AO, njl.
5. Isiseko seplate kunye nemodyuli ye-rack: Ibonelela ngesiseko seplate yokufakelwa kweemodyuli ezahlukeneyo ze-PLC, kwaye ibonelela ngebhasi yokudibanisa phakathi kweemodyuli.Ezinye ii-backplanes zisebenzisaiimodyuli zojongano kwaye ezinye zisebenzisa ujongano lwebhasi ukunxibelelana nabanye.Abavelisi abahlukeneyo okanye iintlobo ezahlukeneyo ze-PLC ezivela kumenzi ofanayo azifani;
6. Imodyuli yoNxibelelwano: Emva kokuxhuma kwi-PLC, inokwenza i-PLC inxibelelane nekhompyutha, okanye i-PLC inxibelelane ne-PLC.Abanye banokufikelela kunxibelelwano kunye namanye amacandelo olawulo, anje ngokuguqula amaza, abalawuli bobushushu, okanye benze inethiwekhi yendawo.Imodyuli yonxibelelwano imele amandla othungelwano lwePLC kwaye imele inkalo ebalulekileyo yokusebenza kwePLC namhlanje;
7. Iimodyuli ezisebenzayo: Ngokuqhelekileyo, kukho iimodyuli zokubala ngokukhawuleza, iimodyuli zokulawula isikhundla, iimodyuli zeqondo lokushisa, iimodyuli ze-PID, njl. Ezi modyuli zinee-CPU zazo ezinokuthi ziqhube phambili okanye zithumele iimpawu zenkqubo yokwenza lula i-PLC CPU yokulawula ulawulo oluyinkimbinkimbi. .Iindidi kunye neempawu zeemodyuli ezihlakaniphile nazo zihluke kakhulu.Kwii-PLCs ezisebenza kakuhle, ezi modyuli zineentlobo ezininzi kunye nokusebenza kakuhle.
