Mayelana nalolu hlelo lokusebenza

Indlela lolu hlelo lokusebenza olusebenza ngayo:

Lolu hlelo lokusebenza lunezinkinga ezingu-17 ezihlukene zikagesi ezikhethwa ngokungahleliwe ukuze zinikeze isipiliyoni sokufunda esijabulisayo nesiyinselele. Kuqinisekile ukukusiza ukuthi ube nekhono ngokwengeziwe ekuxazululeni izinkinga nge-voltmeter. Isiqalisi senjini siyagqwayiza ukuze ukwazi BONA ukucushwa kokuxhumana okuhlukene phakathi kokuya phambili nokuhlehla. Esinye isici esiyingqayizivele salolu hlelo lokusebenza yikhono lokushintshela emuva naphambili phakathi kwe-schematic control kanye ne-PLC logic yesikhathi sangempela. Kukhona futhi "Umsizi Wokuxazulula Inkinga" ukusiza ukuhlola isifunda sokulawula nokuthola izinkinga.

Uhlelo lokusebenza lukwimodi evamile. Lokhu kukuvumela ukuthi uzizwele:
- Isebenza kanjani isiqalo esihlehlayo.
- Isetshenziswa kanjani i-virtual voltmeter probes ukukala ama-voltage ezindaweni zokuhlola ezihlukahlukene (izikwele ezincane ezimnyama, eziphenduka zibebomvu lapho i-voltmeter ithintana nazo) kumjikelezo wokulawula.
- Hlaziya ingqondo ye-PLC, lapho isiqalisi sisezindaweni ezihlukahlukene zokulawula Run (FWD & Rev), Valiwe kanye ne-Auto (FWD & REV).
I-HMI inokulawula ku-Auto kuphela. Isikhethi sishintsha sisebenza njengoba kukhonjiswe yisifunda sokulawula.

Ngemuva kokuthi uqonde ukuthi isiqalisi senjini sisebenza kanjani ezindleleni zokulawula ezahlukahlukene, ungabheka ikhono lakho lokuxazulula inkinga ngokuya kokuthi "Izilungiselelo" (thinta inkinobho ethi 'Okwengeziwe' (phezulu kohlelo lokusebenza) kanye nesithonjana segiya) bese ukhetha imodi yokuxazulula inkinga. Thinta isithonjana "somcibisholo Osemuva" ukuze ubuyele kuhlelo lokulawula. Uzoqaphela ukuthi ingemuva lesikrini lishintshe libe luhlaza okotshani, okubonisa ukuthi sikwimodi yokuxazulula inkinga futhi sinenkinga edinga ukutholwa. Sebenzisa "Umsizi Wokuxazulula Inkinga" phezulu, kwesokudla sohlelo lokulawula ukuze usize ukusetha amaswishi o-opharetha ukuze ahlolwe. Sebenzisa i-voltmeter probes nesikrini esinengqondo se-PLC ukuze uhlonze inkinga. Uma usukholwa ukuthi uhlonze inkinga, cindezela inkinobho ethi "Inkinga Ikhonjiwe" ngaphezulu kohlelo lokusebenza. Kuzovela uhlu lwezinkinga ezingaba khona. Uma ungeke ukwazi ukunquma inkinga, ngaphansi kohlu, kunento enikeza impendulo. Uma ufisa ukubuyisela isistimu yokulawula kokujwayelekile (Imodi Engasiyo Inkinga - Azikho izinkinga zikagesi) ukuze ufunde kabanzi mayelana nendlela okumele isebenze ngayo, hamba esigabeni sezilungiselelo bese uyeka ukukhetha "Imodi yokuxazulula inkinga".

Ngempela iyithuluzi lokufunda elihle kunoma ubani ofuna ukwazi ukusebenzisa ngokugcwele i-voltmeter ukuxazulula inkinga yomjikelezo wokulawula.

Amathiphu Awusizo:

1. Sebenzisa Umsizi Wokuxazulula Inkinga phezulu kuhlelo lokulawula. Inothi "?" isithonjana ukuze usithinte ukuze uthole usizo lokusisebenzisa.
2. Uma uqala ukusebenzisa i-voltmeter yakho, uhlale ufuna ukuqinisekisa ukuthi unamandla okulawula FIRST. Faka i-voltmeter probe yakho ye-VM- kutheminali X2 ne-VM+ ku-X1. Ngemva kokuthuthela amaswishi o-opharetha esimweni sokuhlola esilandelayo, kuyilapho ugcina uphenyo lwe-VM yakho ku-X2, hambisa uphenyo lwakho lwe-VM+ kwesokunxele uye kwesokudla ezindaweni zokuhlola, njalo uqale ngo-1A.
3. Uma ubheka i-PLC logic, gxila emsebenzini ongasebenzi. Isibonelo, uma injini igijima ihlehla, kodwa ingayi phambili, gxila kumqondo ohlobene nokuya phambili (i-logic rung ne-Forward output O:01/00).
