Esimweni esiguquguqukayo seziteshi ze-LNG (Liquefied Natural Gas), izinhlelo zokulawula ezisebenzayo nezithembekile zibalulekile ukuqinisekisa ukusebenza okubushelelezi nokusebenza kahle. Yilapho ikhabhinethi yokulawula ye-PLC (Programmable Logic Controller) ingena khona, iguqula indlela iziteshi ze-LNG eziphathwa futhi ziqashwe ngayo.
Emongweni wayo, ikhabhinethi yokulawula ye-PLC iyisistimu eyinkimbinkimbi equkethe izingxenye eziphezulu, okuhlanganisa ama-PLC omkhiqizo odumile, izikrini zokuthinta, ama-relay, izithiyo zokuhlukanisa, izivikeli zokukhuphuka, nokuningi. Lezi zingxenye zisebenza ngokuvumelana ukudala ikhambi lokulawula eliphelele eliqinile neliguquguqukayo.
Okuhlukanisa ikhabhinethi yokulawula ye-PLC ubuchwepheshe bayo obuthuthukisiwe bokuthuthukiswa kokucushwa, obusekelwe kwimodi yesistimu yokulawula inqubo. Lobu buchwepheshe buvumela ukuhlanganiswa kwemisebenzi eminingi, okuhlanganisa ukuphathwa kwamalungelo abasebenzisi, ukuboniswa kwamapharamitha ngesikhathi sangempela, ukuqoshwa kwe-alamu ngesikhathi sangempela, ukuqoshwa kwe-alamu yomlando, kanye nokusebenza kokulawula iyunithi. Ngenxa yalokho, opharetha banokufinyelela kulwazi oluningi namathuluzi asesandleni sabo, okuthuthukisa ukusebenza kahle kanye nokukhiqiza.
Esinye sezici ezivelele zekhabhinethi yokulawula ye-PLC yi-interface yayo elula ukuyisebenzisa, etholakala ngokusebenzisa isikrini sokuthinta esibonakalayo somuntu nomshini. Lesi sixhumanisi esibonakalayo senza kube lula ukusebenza, sivumela opharetha ukuthi bahambe ngemisebenzi ehlukahlukene kalula. Kungakhathaliseki ukuthi ukuqapha amapharamitha esistimu, ukuphendula ama-alamu, noma ukwenza imisebenzi yokulawula, ikhabhinethi yokulawula ye-PLC inika opharetha amandla okulawula ngokuzethemba.
Ngaphezu kwalokho, ikhabhinethi yokulawula ye-PLC yaklanywa ngokucabangela ukukhulisa nokuguquguquka. Ukwakhiwa kwayo kwe-modular kuvumela ukunwetshwa okulula kanye nokwenza ngezifiso ukuze kuhlangatshezwane nezidingo ezishintshayo zeziteshi ze-LNG, okuqinisekisa ukuhambisana nokuthuthukiswa nokuthuthukiswa kwesikhathi esizayo.
Ekuphetheni, ikhabhinethi yokulawula ye-PLC imelela ubuchwepheshe obuphezulu besistimu yokulawula yeziteshi ze-LNG. Ngezici zayo ezisezingeni eliphezulu, isikhombikubona esibonakalayo, kanye nomklamo ongandiswa, ibeka amazinga amasha okusebenza kahle, ukuthembeka, kanye nokulula kokusetshenziswa ekuphathweni kweziteshi ze-LNG.
