Kuseto kunye nokugcinwa kweenkqubo ezincinci zePLC, amanqaku angonelanga aphumayo yenye yeengxaki eziqhelekileyo ezijongene neenjineli ezizisebenzelayo zaphesheya. I-interface eyakhelwe-ngaphakathi ye-CPU ayanelanga, kwaye ukongeza i-PLC eyongezelelweyo kuya konyusa kakhulu iindleko kwaye kuchaphazele ukusebenza kweendleko zeprojekthi.
Njengomthengisi oqeqeshiweyo, iTekhnoloji yeFeimu ibandakanyeke ngokunzulu kwinkalo yolawulo lweemodyuli zokwandiswa kwamashishini. Siye sayila ngokukodwa i-Siemens 6ES7288-2DE08-0AA0 imodyuli yokuphuma kwedijithali kwiinjineli ze-automation system kunye neengcali zokugcinwa kwezixhobo. Yimodyuli yolwandiso lwedijithali olukhethekileyo lwe-Siemens S7-200 SMART series. Umsebenzi wayo ongundoqo kukongeza i-8 amanqaku okukhutshwa kwe-relay kwi-PLC ngaphandle kwesidingo sokulungisa ingxaki. Inokudityaniswa kwaye isetyenziswe ngokuthe ngqo, ukusombulula ngokulula ingxaki engxamisekileyo yamanqaku angonelanga aphumayo. Ngexesha elifanayo, igcina ukuguquguquka kwenkqubo, okwenza ukuphunyezwa kweprojekthi kube lula.
Silawula ngokungqongqo uMgangatho kuyo yonke le nkqubo. Zonke iimveliso zenziwe ngabavelisi baseTshayina ngokwemigangatho ye-Siemens kunye neenkcukacha. Iyunithi nganye iye yavavanywa ukuze kuqinisekiswe ukuhambelana nozinzo.

Siyazi kakuhle ukuba ukuhambelana kunye nokuqina kwemodyuli yokwandisa kuchaphazela ngokuthe ngqo ukusebenza okuzinzile kwenkqubo yokulawula yonke. NjengoMvelisi oqeqeshiweyo, amajelo ethu okubonelela asemthethweni kwaye ayahambelana. Imodyuli nganye ye-Siemens 6ES7288-2DE08-0AA0 ikhethwe ngokungqongqo, kwaye iimveliso ezihlaziyiweyo zomgunyathi zipheliswe ngokupheleleyo. Phambi kokuthunyelwa, siya kuzicoca iitheminali zemodyuli nganye nganye, sijonge ukuqina kweeclamps, kwaye siqinisekise ukuba imveliso oyifumanayo icocekile ngenkangeleko kwaye iphelele kwiinkcukacha, ibonisa ngokupheleleyo umgangatho wobuchule. Ngokungafaniyo nezinye iimodyuli kwimarike ngokuhambelana kakubi, le modyuli inokubonwa ngokukhawuleza xa iqhagamshelwe kwi-S7-200 SMART CPU. Akukho mfuneko yokucwangciswa kwencwadana yeeparamitha eziyinkimbinkimbi, kwaye awuyi kuba nexhala malunga neengxaki ezifana nokubambelela koqhagamshelwano kunye nokuphazamiseka komqondiso okubangelwa ukuguga kwezixhobo. Ingasetyenziswa ngokuthe ngqo, igcina kakhulu ixesha lokulungisa ingxaki.
Inzuzo ephambili ye-Siemens 6ES7288-2DE08-0AA0 ilele ekulungelelaniseni kwayo kunye neemfuno zokusebenza ezisebenzayo kwisiza. Inqaku ngalinye linokusombulula iintlungu zokwenyani. Eyona nto ihluke kakhulu yimowudi yokukhupha i-relay, edibanisa ukutshintshela kunye nomlawuli, okwenza kube lula ukulawula ukucima kweempawu kodwa kunye nokuqhuba ngokuthe ngqo kwe-220V izixhobo eziphezulu ze-voltage. Akukho zilayidi ezongezelelweyo eziphakathi ezifunekayo, ukuphelisa ngokuthe ngqo indleko yokuthengwa kweekhonkco eziphakathi kunye nokwenza lula inkqubo yocingo, okwenza ukuba ukuhlelwa kwekhabhinethi yolawulo kube mfutshane ngakumbi.
Uyilo lwebhloko ye-plug-in terminal isebenziseka kakhulu. Iingcali zogcino lwezixhobo ziyazi ukuba xa utshintsha iimpazamo zemodyuli, ukuphinda kufakwe iintambo kudla ixesha kwaye kuthande ukuba neempazamo. Nangona kunjalo, ibhloko ye-terminal yale modyuli inokudityaniswa ngokuthe ngqo kwaye ikhutshwe. Xa utshintsha imodyuli, vele ukhuphe ibhloko ye-terminal endala kwaye ufake imodyuli entsha ngokuthe ngqo, ngaphandle kokuphinda udibanise, ugcine ixesha kunye nomgudu kunye nokuphucula kakhulu ukugcinwa kokusebenza kakuhle.
Ukongeza, inomsebenzi wokuzihlukanisa we-optocoupler, onokuxhathisa ngokufanelekileyo uphazamiseko olwahlukeneyo lwe-electromagnetic kwiindawo zoshishino, ukunqanda ukungasebenzi kakuhle kwezixhobo okubangelwa kukuphazamiseka kwemiqondiso. Nakwiimeko zemizi-mveliso entsonkothileyo, inokugcina ukusebenza okuzinzile kwaye ilungele iimeko ezahlukeneyo zolawulo oluzenzekelayo lwe-automation. NjengoMzimveliso obandakanyeka ngokunzulu kushishino, sidibanisa amava asebenzayo kwindawo yokuqinisekisa ukuba inqaku ngalinye linokwanelisa iimfuno zokwenyani zokusetyenziswa kweenjineli.
Kwiiprojekthi ezincinci ezizenzekelayo kunye nokugcinwa kwezixhobo, ukulawulwa kweendleko kubaluleke kakhulu. Siye sasungula le modyuli ye-Siemens 6ES7288-2DE08-0AA0 ukwenzela ukuba abalingane bamazwe angaphandle basombulule ingxaki yamanqaku angonelanga aphumayo kwiindleko zezoqoqosho. Le mveliso iyafikeleleka kwaye ineendleko eziphezulu.
Kwangaxeshanye, zonke iimveliso esizinikezelayo zintsha kraca. Zinembonakalo ecocekileyo, ukusebenza okuzinzile, kwaye zihambelana ngokupheleleyo ne-S7-200 SMART system. Akukho zincedisi ezongezelelweyo ezifunekayo. Nje ukuba zifunyenwe, zinokufakelwa ngokuthe ngqo kwaye zilungelelaniswe ukuze zisetyenziswe, ukonga ngakumbi utyalo-mali lweprojekthi kunye neendleko zokuyigcina, yenze ukuba ibe lukhetho oluneendleko eziphezulu zokwandiswa kweenkqubo ezincinci zePLC.
Umbuzo: Ngaba le modyuli ingasetyenziswa ngokuthe ngqo kunye nazo zonke ii-CPU ze-S7-200 SMART series ngaphandle kwesidingo sokucwangciswa ngesandla?
