Kulo lonke uphuhliso lwe-automation ye-industrial, kuhlala kukho iimveliso zakudala ezihlala ziqinile kwimigca yemveliso yeefektri ezindala nasemva kwamashumi eminyaka. I-Allen Bradley 1785-L20E ngomnye umzekelo onjalo. Njengomthengisi oqeqeshiweyo, i-Feimu Technology iye yabandakanyeka ngokunzulu kugcino lweenkqubo zolawulo lwemizi-mveliso endala kwaye izazi kakuhle iindawo ezibuhlungu zeengcali zogcino lwaphesheya kweelwandle kwizixhobo ezindala - imigca yemveliso ephelelwe lixesha isendleleni yokukhutshwa, kodwa bayaxinga ngenxa yokusilela kweprosesa engundoqo. Iindawo ezinqabileyo ezisecaleni kunzima ukuzifumana kwaye namaxabiso aphezulu.
Le 1785-L20E yeye Rockwell Automation PLC-5 series. Silawula ngokungqongqo umgangatho kuyo yonke inkqubo. Zonke iimveliso ziphindaphindwa ngabavelisi baseTshayina ngokwemigangatho yokuqala yefektri. Ngamnye uye wenza uvavanyo olusebenzayo lokulungelelanisa inkqubo yenkqubo endala ukuqinisekisa ukuhambelana okugqibeleleyo kunye nezixhobo ezindala. Okwangoku, kukho unikezelo olwaneleyo lweemveliso, kwaye akukho mfuneko yokulinda ixesha elide. Iiodolo zinokuthunyelwa ngokukhawuleza xa zibekiwe. Le mveliso inegalelo ekuqhubekeni kokusebenza kwemigca emidala yokuvelisa.

Kwabalingane abagcina izixhobo ezidala ukusuka kwi-1990 ukuya ekuqaleni kwe21st inkulungwane, ixabiso le-1785-L20E libonakala ngokwalo. Ayisiyo iprosesa yokusika elandela isantya esiphezulu sangoku, kodwa "yinkosi yoomatshini" yelo xesha, exhotyiswe nge-interface ye-Ethernet ejonge phambili kakhulu ngelo xesha. Le yeyona nzuzo iphambili. Njengomvelisi oqeqeshiweyo, sicacile malunga neendawo zentlungu zeenkqubo zakudala - ezininzi ze-PLC ezindala azinamsebenzi wokunxibelelana, kwaye ukulungiswa kweempazamo kunye nokubeka iliso konke kwenziwa ngokusebenza kwisayithi, okubangela ukusebenza okuphantsi. Le Allen Bradley 1785-L20E iprosesa iza ne-10Base-T Ethernet interface. Akukho mfuneko yokuthenga iimodyuli zonxibelelwano ezinqabileyo ngokwahlukeneyo. Yifake nje kwintambo yenethiwekhi kwaye inokunxibelelana ne-RSLogix 5 software, ivumela ukukhuphela inkqubo ekhawulezayo nefanelekileyo, kwaye ikwavumela ukutshintshiselana kwedatha ngexesha langempela kunye nenkqubo yekhompyuter. Oku kuvumela izixhobo ezidala ukuba zibe nezakhono zala maxesha zokubeka iliso kuthungelwano ngaphandle kwesidingo sokutshintshwa kwenkqubo epheleleyo, ngaloo ndlela kuphuculwe ngokubonakalayo ugcino olusebenzayo.
Undoqo we-Allen Bradley 1785-L20E yi-CPU ezinzile kakhulu, ejikelezwe ngamacwecwe amaninzi okugcina ukuqinisekisa ukuzinza kokugcinwa kweprogram kunye nokusebenza. Ibhodi yesekethe yangaphakathi yamkela uyilo olubanzi, olwaluluncedo kakhulu ngelo xesha kwaye inokumelana ngokufanelekileyo nokuphazamiseka kwe-electromagnetic kwimimandla yemizi-mveliso, ukunqanda ukuphazamiseka komqondiso okukhokelela ekusileleni kwezixhobo. Nakwimekobume yefektri endala entsonkothileyo, inokusebenza ngokuzinzileyo.
Uyilo lokutshatyalaliswa kobushushu nalo luthatha ingqiqo. I-baseplate yensimbi ibambelela ngokuthe ngqo kwizinto eziphambili zokuvelisa ukushisa, okuvumela ukutshatyalaliswa kobushushu okukhawulezayo kunye nokukhusela umonakalo wecandelo ngenxa yokugqithisa ngexesha lokusebenza kwexesha elide. Esi sesona sizathu sibalulekileyo sokuba inokuhlala ixesha elide. Umva usebenzisa i-interface yohlobo lwe-1771, enezikhonkwane ezishinyeneyo kunye nonyango olujiyileyo lwegolide. Ukufakwa kunye nokutsalwa kugudile kwaye unxibelelwano luqinile. Nangona izixhobo ezidala zisebenza kwaye zivelisa ukungcangcazela okunamandla, akuyi kubakho ukusilela koqhagamshelwano okanye ukuqhawulwa komqondiso, ukulungelelanisa ngokugqibeleleyo kwimeko yokusebenza yezixhobo zefektri endala. NjengeFactory ebandakanyeka ngokunzulu kwishishini, senza uhlolo lwesibini kwiinkcukacha zesakhiwo semveliso nganye ukuqinisekisa ukuba iyakwazi ukuziqhelanisa neemfuno zofakelo kunye nokusebenza kwenkqubo endala.
Asizange siyibaxe indlela yokusebenza kwale prosesa. I-advanteji ye-Allen Bradley 1785-L20E ayilali kwisantya esiphezulu se-computing - xa kuthelekiswa nesizukulwana esitsha sabalawuli, isantya sayo sokukhangela ingqiqo asikho ngaphezulu. Nangona kunjalo, xa kusingathwa imisebenzi ephambili yenkqubo endala, iyasebenza ngokwaneleyo kwaye inokuthenjwa. Ingaba i-relay logic control control, i-sequential control, okanye i-PID elula yokulawula, ingabaphatha ngokulula, ngaphandle kokulibaziseka, ukuhlangabezana ngokupheleleyo neemfuno zolawulo lomgca wemveliso endala.
Kwinkqubo endala, ukuzinza kubaluleke ngakumbi kunesantya. Ukuzinza kwe-1785-L20E kuye kwaqinisekiswa kwiindawo zoshishino amashumi eminyaka. Iimveliso esizibonelela ngazo zonke ziye zatyhubela iimvavanyo ezingqongqo zokusebenza ukuqinisekisa ukuba nganye inokuphindaphinda ngokugqibeleleyo ukusebenza komzi-mveliso wokuqala. Emva kokudibanisa kwinkqubo endala, akukho mfuneko yokulungiswa kweengxaki ezinzima, kwaye inokusetyenziswa ngokukhawuleza, ukusombulula ingxaki yokumisa umgca wemveliso obangelwa kukungaphumeleli kweprosesa endala, evumela ukuba izixhobo ezidala ziqhube ukuba zixabiseke kwaye zigcine inkampani iindleko ezinkulu zokutshintsha inkqubo entsha.
Ukugcina iinkqubo ezindala, ukulawulwa kweendleko kubalulekile. Nangona kunjalo, ixabiso eliphezulu leentsimbi ezinqabileyo lihlala liwushiya umsebenzi wolondolozo usengxakini. Siye saphehlelela le Allen Bradley 1785-L20E ukwenza oogxa baphesheya kolwandle basombulule ingxaki yokunqongophala kwenxalenye yespare kwiinkqubo ezindala ngexabiso elithe kratya loqoqosho. Le mveliso iyafikeleleka kwaye ibonelela ngeendleko eziphezulu. Sisusa umbindi we环节 kwaye sihambise ngokuthe ngqo iimveliso ezikumgangatho ophezulu kubathengi, sinciphisa kakhulu iindleko zokuthengwa kwenxalenye esecaleni. Kwangaxeshanye, zonke iimveliso esizinikezelayo zintsha kraca. Imbonakalo iphinda uyilo lwakudala, kwaye ukusebenza kuyahambelana nomzi mveliso wokuqala. Nje ukuba zifunyenwe, zinokufakelwa ngokuthe ngqo kwaye zilungelelaniswe ngaphandle kokulungiswa kwempazamo okanye ukusetyenzwa. Oku konga ngakumbi ixesha lolondolozo kunye neendleko zabasebenzi, nto leyo eyenza kube lukhetho olungabizi kakhulu kugcino lweenkqubo ezindala.
