Hoʻolauna
Hoʻolālā ʻia ke keʻena lawe kinoea kūikawā no ka hoʻolako ʻana i nā kinoea puhi ahi, pahū, corrosive, ʻona a me nā kinoea ʻē aʻe.
Hiki ke hoʻokaʻawale ʻia ka ʻōnaehana i nā ʻāpana: piha piha, semi-aunoa a me ka hana lima.ʻO nā hana maʻamau ka hoʻomaʻemaʻe maʻemaʻe, ka hoʻololi ʻana a me ka ʻoki ʻoki ʻana i ka palekana i nā kūlana ulia pōpilikia (i ka wā e hoʻāla ʻia ai ka hōʻailona alarm).
Hoʻomalu ʻia ka pahu ʻea kinoea e ka PLC, ʻo ka pā paʻi he kanaka-machine interface, a hoʻokomo ʻia ka sensor kaomi e ka mea.
ʻO nā mea hana e like me ka ea-conditioning device, pneumatic valve, flow meter, a me nā mea'ē aʻe, eʻike i ka hana palekana a me ka pono o nā mea hana.ʻO kāna hana PLC papahana palekana interlock o ka mika a me ke koho kūpono a me ka hoʻonohonoho ʻana o nā ʻāpana valve maʻemaʻe kiʻekiʻe e hoʻokō i nā koi o ke kaʻina hana semiconductor.
ʻO nā koi no ka hoʻolako mau ʻana a me ka hoʻomaʻemaʻe kiʻekiʻe o nā kinoea kūikawā i ka waena, akā no ka hōʻoia ʻana i ka hana maʻamau o ka hale hana a me ke ola pilikino o nā limahana palekana.
