Ngaba i-PCS yamashishini ibuyisela ii-PCCs?
2025-11-11
Ngokwemisebenzi yolawulo, iikhompyuter zingenza yonke into enokuthi yenziwe zii-plcs, kwaye ngamanye amaxesha iikhompyuter zinokwenza ngcono nangakumbi. I-PCS PCS ithathe indawo yokutshintsha ii-Plcs kwi-PLCS yenkqubo yolawulo lwamashishini, kodwa kukho umahluko okhoyo phakathi kwaba bobabini ngokwendlela yokusebenza, ukuthembeka, kunye nokukhetha kufuneka kwenziwe ngokusekwe kwiimfuno ezithile.
Ukusebenza kokusebenza Imisebenzi yabo ephambili yolawulo lwe-Logic (njengenkqubo yomzobo we-ladder), impendulo yexesha lokwenyani, kunye nezakhono zokuphazamiseka. Zilungele ukuphatha imisebenzi esisiseko yokulawula njengokuguqula ubungakanani, amaxesha kunye nezinto zokubala.
Ukuthembeka kunye nokuQiniseka kokusiNgqongileyo
Ii-PlCs zisebenzisa uyilo lwebanga lokusebenza kwezamashishini (ezinje ngokusebenza angenakufunyanwa, uluhlu lwamaqondo obushushu, uthuli kunye nokunganyangeki kwamanzi), ukunika umsebenzi ozinziweyo kwi-encromimagnetic kunye nentshukumo ye-Electromagnetic kunye ne-MTBF) yeeyure ezingama-20,000.
Ixabiso kunye nolondolozo
Ii-PLCs zineendleko eziphantsi, kulula ukuzigcina, kwaye zibe nejika eliphantsi lokufunda lenkqubo ye-ladder ye-ladder, ibenza bafaneleke kwiiprojekthi ezincinci zokulawula.
Ii-PCS zemveliso zibiza kakhulu kwaye zifuna ulondolozo lobuchwephesha, zibenza bazilungele iimeko ezifuna ukubalwa okuBanzi okanye ukunxibelelana ngomatshini.
Isicelo
I-plc: isetyenziswe kwizicelo ezifuna ukuSebenza okungaphezulu kwexeshana kunye nokuthembeka, ezinje ngolawulo lwelayini, izixhobo zokungenelela, kunye nokhuseleko lokhuseleko.
I-PC yeShishini: isetyenziswe kwizicelo ezifuna i-computing yokusebenza ephezulu, njengokufunyanwa kwedatha, ihloli ekubonelelwe, kunye nolawulo olusasazwayo; ihlala isetyenziswa ngokudibeneyo ne-plc.
Iindlela zeTekhnoloji: Ezinye ii-PC eziphezulu zeshishini eziphezulu (ezinje ngeenkqubo ezenzekelayo ze-PC) zisetyenzisiwe kwizicelo ezinzima zolawulo ezifana noyilo lwemveliso yemoto kunye nogcino lwemodyuli kwaye ziyafuneka ukuqinisekiswa ukuthembeka.
I-B5300 ye-B5300 ye-fan engenamsebenzi isebenzisa i-Intel ye-Intel ye-Intel® //1 I-Atom / proces Proces, ukuqinisekisa ukusebenza okuzinzileyo.
Isebenza i-24 / 7, igcina umsebenzi ozinzileyo nakwimeko ezingazithembanga, ihlangabezana neemfuno zezinto ezahlukeneyo zorhwebo, ezenzekelayo, kunye nezixhobo ezingafakwanga. Kwiimeko ezithile, inokutshintsha ngokupheleleyo izixhobo zokulawula amashishini plc.
Ii-PCS zemveliso kunye nee-PLCs nganye zinezibonelelo zabo ezizodwa kunye nezicelo kwi-automatist yemveliso. Kwixa elizayo, banokubonisa imeko yokuhlangana, kodwa kunokwenzeka ukuba umntu utshintshwe enye incinci.
Ukususela oko kwangeniswa kwimveliso yezomzi-mveliso yokuqala ekuqaleni kweminyaka yo-1990, i-PCS yeshishini ingena kwiindawo ezahlukeneyo kwaye ifumana usetyenziso olubanzi. Oku kungenxa yokuvula kwee-PC, izixhobo zabo ezininzi, isoftware, kunye nemithombo yabasebenzi, inkxaso yabo kuluhlu olubanzi lwabaphulaphuli bezobunjineli, kunye nokwazi kwabo abaphulaphuli abaninzi. Iqondo lokwenza isicelo sePC (kubandakanya ii-PC ezifakelweyo ii-PC) iinkqubo zokulawula imizi zikhule ngokukhawuleza. Abavelisi abaphambili be-Logic office (PlC) abavelisi benkqubo yokulawula umzi-mveliso baye bamkela indlela yeTekhnoloji ye-PC, esenza itekhnoloji yolawulo lwe-PC, esenza itekhnoloji yolawulo lwePC.
Ixabiso eliphantsi le-PCS lemizi-mveliso yenye into ebalulekileyo ebangela ukuba igalelo labo njengeyona nto iphambili kulawulo lwemizi-mveliso. Iinkqubo zeZentlalo ezizezikhulu, ezenzekelayo zenziwa ikakhulu zii-PLCs kunye neDCSs, ngelixa inkqubo kunye nenkqubo yenkqubo kunye ne-Minicroprivers. Ixabiso eliphezulu lezixhobo zabo ze-Hardware, isoftware yenkqubo, kunye nesoftware yesoftware inika iinkampani ezininzi. Kwangoko ukuya kwinqanaba eliphakathi lophuhliso lwamashishini, ukukhetha i-Auto olwenziwe ngexabiso eliphantsi kweMizi-mveliso yeyona ndlela ikhethwayo. Ngaphaya koko, kuba abalawuli-ngokusesikweni bePC iqinisekiswe ukuba bathembeke njengee-PLC, bamkelwe ngokulula ngabaqhubi, kulula ukuyisebenzisa, kwaye banikele imisebenzi yokuxilongwa, babonelela ngenkqubo yokudibanisa izinto eziguqulweyo. Ke ngoko, abavelisi abangaphezulu baqala ukwamkela izisombululo zokulawula ukulawula amashishini kwiindawo ngeenkqubo zabo zemveliso.
Kuyabonwa kwangaphambili ukuba ukhuphiswano phakathi kwee-PCS zeshishini kunye nee-plc ziya kugxila ikakhulu kwizicelo zokuphela, apho idatha ihamba khona kwaye ukudityaniswa kwezixhobo kuphezulu. Ukujonga iindlela zophuhliso, ikamva leenkqubo zokulawula liya kuxoka phakathi kwee-PCS zeshishini kunye nee-PLC, kwaye imiqondiso yokuhlangana sele ivele. Ixesha elibonakalayo elizayo, itekhnoloji ye-filbus, abalawuli be-ogic esebenzayo (ii-PLCs), kunye ne-PCS yezamashishini baya kuba bekhulisa, kodwa izibonelelo ze-PCS ziya kuba zidume ngakumbi kuzo zonke iindawo zolawulo lwezolimo.
Iinkqubo ezihlanganisiweyo zolawulo kunye neenkqubo zolawulo
Ngokukwenza ungene kwi-Intanethi ye-Intanethi kwicandelo lolawulo lwemizi-mveliso, ukudityaniswa kolawulo kunye neenkqubo zolawulo kuyenzeka. Oku kwenza ukuba kubekho iinjongo ezinqwenelekayo zolawulo oluhlangeneyo nolawulo, ulwazi lwamashishini olushishino, kunye nenethiwekhi ezenziwe ngenethiwekhi kwishishini lemizi-mveliso. Ulawulo oluhlanganisiweyo kunye nolawulo luvumela amashishini ukuba akhethe ezona zisombululo zilungileyo zilungele ixesha elitsha loqoqosho, ngaloo ndlela ziphucula ukusebenza kakuhle kwentengiso. Ke ngoko, isikhokelo esitsha ekuphuhlisweni kwetekhnoloji yolawulo lwemizi-mveliso kukufezekisa i-ECHEARMY Systegies nge-Ethernet kunye neTekhnoloji yeWebhu, inikezelwe kwimodyuli yokulawula imizi-mveliso esekwe kwi-Ethernet nakwi-TCP / IPROLY IMIQATHANGO. Eyona nto ibaluleke kakhulu kukuphuhliswa kolawulo lweshishini olusekwe kwinethiwekhi kunye nesoftware yolawulo.
Ulwakhiwo lwenkqubo yokulawula oluhlanganisiweyo lubandakanya ukudityaniswa kweenkqubo ezininzi kunye netekhnoloji. Ngokuphathelele ukudityaniswa kweenkqubo ezininzi, inkalo yokuqala kukudityaniswa kweenkqubo ezininzi kwinethiwekhi yolawulo lwentsimi, kubandakanya iimodeli ezintathu zokudibanisa. Eyokuqala kukudityaniswa kweenkqubo zokulawulwa kwe-filbus (i-FCS) kunye neenkqubo zolawulo lwedatha (i-DCS), apho i-FCS iphumeza imilinganiselo yenqanaba eliphezulu kunye nomququzeleli wokuphumeza imisebenzi enobunzima bokulawula nolawulo. Okwesibini kukudityaniswa kweenkqubo zokulawulwa kwe-filbis (i-FCS, kunye nee-PCs, apho, kwiimeko ezinobunzima bokulinganisa kunye ne-DCS imisebenzi yokuphumeza imisebenzi enobunzima bokulawula nolawulo. Okwesithathu kukudityaniswa kwe-FCSS emininzi, ukujongana nemicimbi yokuguqula phakathi kweeprothokholi zonxibelelwano ezahlukeneyo. Oku kubandakanya ukugxila ekusebenzeni kwezixhobo ezahlukeneyo zentsimi kunye nokuqulunqwa koqwalaselo oluhlanganisane, ukubeka iliso, kunye nesoftware yokufumana ukudityaniswa kunye nokuchaphazela ukusebenza kunye nokusebenza kwenkqubo nganye ezimeleyo. Okwesibini, kukho ukudityaniswa kolawulo kunye nolawulo lweenethiwekhi. Kulawulo lweshishini elizayo, inani elikhulu ledatha liya kuqala kwinethiwekhi yolawulo. Ukwakha isoftware yesoftware yesoftware, kubandakanya nogcino lwexeshana, oovimba beembali, ukumiswa kwedatha, ukubelwa kwedatha, ukubekwa kwengxelo, kunye nokusetyenziswa kwemali, i-Rection, iParamenti yokuSebenza, kunye nokuSebenza kweNtlawulo yeNdawo efikelela kulawulo oluhlanganisiweyo kunye nolawulo lwewebhu. Oku kubonelela ngenkxaso yokuthatha isigqibo sokwenza izigqibo kwisoftware yolawulo kunye nedatha exabisekileyo kwisoftware yolawulo.
Ngokwendlela yokudityaniswa kwetekhnoloji, oku kubandakanya ukudityaniswa kwetekhnoloji eyahlukeneyo efana neTekhnoloji yoTekhnoloji, itekhnoloji yoTshintshiselwano gadalala, i-Ethernet, nakwi-Ethernet yeMveliso. Itekhnoloji yoTshintshiselwano ngokuBanzi ibandakanya iTekhnoloji yoTekhnoloji ye-DDE, iNethiwekhi yeNethiwekhi yeNethiwekhi, i-ODBC iVument Cechnology Technology, com / itekhnoloji ye-OPCO. I-Ethernet + TCP / / itekhnoloji ye-IP inika ugqithiso ngqo kunye nokwabelana ngeeparamitha zolawulo kunye nenqanaba leendawo ezinemizi-mveliso, i-DCSS, neFCS ngenxa yobukho beprotokholi ezininzi.
Ukusebenza kokusebenza Imisebenzi yabo ephambili yolawulo lwe-Logic (njengenkqubo yomzobo we-ladder), impendulo yexesha lokwenyani, kunye nezakhono zokuphazamiseka. Zilungele ukuphatha imisebenzi esisiseko yokulawula njengokuguqula ubungakanani, amaxesha kunye nezinto zokubala.
