Ukufinyelela kude ku-HMI ngaphandle komsitshi wewebhu womphakathi
Gcina i-HMI ngaphandle kwe-inthanethi yomphakathi futhi uxazulule isenzo esisodwa esigunyaziwe ngesango, ubunikazi besethi ebhalisiwe kanye neseshini ongayihoxisa uma kudingeka.
Ukukhombisa ikhasi lesimo somshini kuthebhu yesiphequluli akufani nokulawula ithuluzi elingemuva kwayo. I-HMI kufanele ihlale iyimfihlo kuyilapho insizakalo encane eboshelwe kumgomo ixazulula isenzo esisodwa umsebenzisi asidingayo. Nquma umsebenzi, ubunikazi kanye nendlela yokuhoxisa ngaphambi kokukhetha umkhiqizo. Ukuthutha ingxenye elula yokushintsha; imodeli yokugunyaza ayiyona.
Khetha umsebenzi ngaphambi kokuthutha
Ukufunda ikhasi lesimo, ukuthola umbiko ogunyaziwe kanye nokushintsha iphoyinti lokusetha kuyizicelo ezintathu ezihlukene. Okokuqala kungeneliseka ngokubuka kokufunda kuphela; okokugcina kuthinta isimo sethuluzi futhi kudinga imvume ecacile yomnikazi, iwindi lokulungisa kanye nokuqondisa kwendawo. Ukuzihlanganisa ngaphansi kokufinyelela kude kufihla lowo mehluko futhi ngokuvamile kukhiqiza indlela ebanzi kunalokho okudingwa umsebenzi. Qamba umsebenzi, indima evunyelwe ukuwenza kanye nobufakazi bokuthi kwenzekile.
Ngemva kwalokho ukuthutha kulandela umsebenzi hhayi okuphambene nalokho. Isidingo sokufunda kuphela asivamisile ukuthethelela ukulawula okusebenzisanayo, futhi ukulawula okusebenzisanayo akuvamisile ukuthethelela ukuveza umsitshi we-HMI ngokwawo. Uma umsebenzi usubhaliwe, imodeli yokufinyelela iba isinqumo hhayi okuzenzakalelayo komkhiqizo.
Beka umxazululi phambi kwensiza eyodwa eqanjiwe
Isango lensiza liqinisekisa umsebenzisi, lisebenzisa inqubomgomo futhi livula ukuxhumana nensizakalo eyodwa eyimfihlo. I-HMI igcina umsitshi wayo kunethiwekhi eyimfihlo futhi ayikaze yamukele amaseshini avela ku-inthanethi. Isango liqeda iseshini ebethelwe, okulenza libe umngcele wokwethenjelwa wombhalo ocacile okufanele othile awulawule futhi awuqaphe.
Lowo mngcele uwukwakhiwa ngokwawo, hhayi umphumela oseceleni. Bhala lapho ukubethela kuphela khona, ubani ophethe izikhiye zesango kanye nokuthi yiliphi ithimba elingashintsha inqubomgomo yalo.
| Model | Where the session ends | Fits when |
|---|---|---|
| Browser gateway | At the broker, then a narrow proxy connection to one HMI service | Read-only pages and approved actions with per-user policy |
| Site engineering workstation | On a controlled host inside the site network | The tool needs local discovery or a legacy client |
| Outbound site connector | At the connector, brokered from outside | No new inbound path to the site is allowed |
Umgqa ngamunye uthwala indlela ehlukile yokwehluleka. Isango lincike kunqubomgomo yalo kanye nochunge lwezitifiketi, isiteshi sokusebenza sendawo sincike ekulawuleni komzimba nasekubalweni kwe-akhawunti yendawo, futhi isixhumi esiphumayo sincike ekufinyelelekeni komxazululi. Khetha umgqa ohambisana nomsebenzi, bese ubhala ukuncika okukulethayo.
Ikheli wukuhamba kwendlela, ubunikazi wukugunyaza
Ikheli lethuneli noma igama le-DNS litshela inethiwekhi lapho kufanele kuthunyelwe khona amaphakethe; alitsheli umxazululi ukuthi yimuphi umshini umsebenzisi ayewuqonda. Bhalisa i-HMI ngayinye noma isixhumi sendawo ngobunikazi obuhlukile futhi uhlanganise lobo bunikazi nerekhodi lempahla. Uma ikheli lishintsha, ubunikazi busakhetha impahla efanele. Uma ubunikazi buhoxiswa, okufakiwe empahleni kukhombisa ukufinyelela okunyamalalayo.
I-DNS eguquguqukayo ibuyekeza irekhodi futhi akukho okunye. Ayinikezi ukugunyazwa komsebenzisi noma indlela enqamula isihumushi ngasinye esiphezulu, futhi ukuyithatha njengokulawula ukufinyelela yiyo indlela igama elidala eliqhubeka nokusebenza ngayo ngemva kokuhoxiswa emsebenzini. Isixhumi esiphumayo esisekelwayo sigwema indlela entsha yokungena engaceliwe, kodwa sisadinga imvume yomnikazi wenethiwekhi kanye nokuziphatha okubhaliwe uma umxazululi ungafinyeleleki.
Khawulela iseshini futhi ufake ubufakazi bokuhoxisa
Nikeza umsebenzisi ngamunye ubunikazi obuhlukile, funa ukuqinisekiswa kwezici eziningi futhi unikeze kuphela izenzo ezidingwa umsebenzi. Setha iwindi lokulungisa enqubomgomeni hhayi kunothi lekhalenda. Vikela imininingwane yokungena nedatha yomsebenzi iseshini esithintayo, futhi gcina izehlakalo zokufinyelela ngaphandle kokuqoqa umsebenzi womsebenzisi ongahlobene.
Ukuhoxisa kufanele kuhlolwe kuyilapho iseshini isaphila. Susa ilungelo lomsebenzisi, qeda iseshini kumxazululi, futhi qinisekisa ukuthi i-HMI ayisafinyeleleki ngale ndlela.
Bese ujwayeza ukwehluleka okuthiwa uhlelo luyakunqoba: misa umxazululi noma nqamula ithuneli futhi uqinisekise ukuthi ukusebenza kwendawo nokubuyisela kusasebenza. Ukwakhiwa okusebenza kuphela uma indlela ekude iphilile akulona uhlelo lokufinyelela kude. Bhala usuku, umqhubi kanye nomphumela, ngoba umhloli olandelayo uzocela ubufakazi hhayi inhloso.
