Kua tino whanake haere ngā taputapu ahumahi i ngā tekau tau kua pahure ake nei, i te wā i herea ai te nuinga o ngā taputapu ki te putanga anaro 4-20mA, 0-20mA rānei e rite ana ki te taurangi tukanga. I hurihia te taurangi tukanga ki tētahi tohu anaro motuhake i tukuna mai i te taputapu mā te waea-2 ki tētahi pūnaha tohu, ki tētahi pūnaha whakahaere rānei, me te whirihoranga maha-taka, e hiahia ana kia uru tika mai ngā kaimahi tiaki mō ngā whakatikatika ā-ringa.
Kua kitea i muri mai ngā painga pea o te hangarau matihiko i roto i ngā taputapu. Tērā pea he nui ngā raraunga me ngā mahi whai hua kei roto i tētahi taputapu, pērā i te whirihoranga o te taputapu, ngā rohe whakaoho, te wā mahi me ngā āhuatanga, ngā mōhiohio tātaritanga, me ētahi atu. Mā te whiwhi i aua raraunga ka āwhina i te arotau i te mahi a te taputapu, ā, i te mutunga ka whakapai ake i te mahi a te tukanga.Kawa HARTi puta mai hei tētahi o ngā huarahi tōmua ki te uru atu ki ēnei raraunga kua pakaru hei hanga i ngā taputapu kia atamai.
Mā te hangarau HART ka taea te whakawhitiwhiti kōrero ki tētahi taputapu anaro mā te whakamahi i tētahi tohu whakawhitiwhiti matihiko e tukuna ana i runga i te waea-rua kotahi me te putanga anaro. Nā tēnei tohu matihiko i whakarato ngā whakawhitiwhiti kōrero-rua i waenga i te taputapu me te kaihautū me te kore e whakararuraru i te putanga, e whakahaere ana i te urunga atu ki ngā momo raraunga. Mā te HART, ka taea e ngā kaimahi te whakawhitiwhiti kōrero ki tētahi tuku me te mahi whirihoranga, tātaritanga rānei i a ia e mahi ana i te ine tukanga wā-tūturu.
Tukunga Pēhanga Pāmahana Teitei a WangYuan WP421A me te Putanga Kawa HART 4~20mA
I taua wā anō, i haere tonu te whanaketanga o ētahi atu hangarau matihiko ka tukuna mā roto i ngā huarahi whakawhitiwhiti kōrero motuhake, ia huarahi e tuku ana i ngā painga motuhake, tae atu ki te hangarau Fieldbus māngai oKawa Modbus me te atanga RS-485He kawa tuwhera matua-pononga raupapa a Modbus, e āhei ai ngā kaihanga katoa ki te whakauru i te kawa ki roto i tētahi taputapu, hei whakarato urunga ā-rohe ki ngā taputapu atamai mai i ngā pūnaha manaaki.
Tuku Pēhanga WangYuan WP401A me te Putanga Modbus RS485 me te Ārai-Ex
Nā te whanaketanga o te hangarau i roto i te haurua rautau kua pahure ake nei, kua whanake te tuku taputapu mai i te taurangi tukanga matua anake ki te nui o ngā mōhiohio e wātea ana tae atu ki te taumata hinonga. I ngā rā kei te heke mai, ka haere tonu te hangarau matihiko ki te whakarato i ngā taipitopito atu i ngā tuku, me te whānuitanga o ngā huarahi urunga.
I WangYuan, he kaihanga Hainamana me te neke atu i te 20 tau o te wheako nui ki te ao taputapu, ka whakatairangahia e mātou te tono o ngā putanga whakawhitiwhiti atamai mō ngā hua o ngā taputapu ine. Ko te nuinga o ā mātou hua mō te ine i te pēhanga, te taumata, te pāmahana me te rere ka whakaaetia kia whakaritea te putanga tohu tae atu ki te HART Protocol kua rēhitatia ki te turanga me te RS-485 Modbus hei whakatutuki i ngā hiahia o ngā kaiwhakamahi me te āhua o te mara.
