ʻO Programmable Logic Controller (PLC) he ʻōnaehana uila uila i hoʻolālā ʻia no nā noi ma nā wahi ʻenehana.Hoʻohana ia i kahi hoʻomanaʻo programmable no ka mālama ʻana i nā ʻōlelo aʻoaʻo no ka hoʻokō ʻana i nā hana loiloi, ka mana sequential, ka manawa, ka helu, a me nā hana helu i loko.Hoʻomalu ia i nā ʻano mea hana mechanical a i ʻole nā kaʻina hana ma o ka hoʻokomo a me ka hoʻopuka kikohoʻe a i ʻole analog.
ʻO ka Programmable Logic Controller (PLC) kahi mea hoʻoponopono helu helu me kahi microprocessor no ka hoʻokele aunoa, hiki ke mālama a hoʻokō i nā ʻōlelo aʻoaʻo i ka hoʻomanaʻo kanaka i kēlā me kēia manawa.Hoʻokumu ʻia ka mea hoʻoponopono programmable me nā ʻāpana hana e like me CPU, ke aʻo ʻana a me ka hoʻomanaʻo ʻana i ka ʻikepili, hoʻokomo / puka puka, lako mana, kikohoʻe i ka hoʻololi analog, a me nā mea ʻē aʻe. ua kapa ʻia ʻo programmable logic controllers.Ma hope mai, me ka hoʻomohala mau ʻana, ua loaʻa i kēia mau modula kamepiula me nā hana maʻalahi i ka hoʻomaka ʻana i nā hana like ʻole, e like me ka mana logic, ka mana manawa, ka mana analog, a me ka kamaʻilio mīkini lehulehu.Ua hoʻololi hou ʻia ka inoa i Programmable Controller, akā naʻe, ma muli o ka paio ma waena o ka abbreviation PC a me ka abbreviation Personal Computer, a ma muli o nā kumu maʻamau, hoʻohana pinepine ka poʻe i ka huaʻōlelo programmable logic controller, a hoʻohana mau i ka abbreviation PLC.ʻO ke kumu o ka PLC programmable logic controller he kamepiula i hoʻolaʻa ʻia i ka mana ʻoihana.ʻO kāna mau mea maʻamau: ka mana lako module, CPU module, memory, I/O input and output module, backplane and rack module, communication module, functional module, etc.
PLC Programmable Logic Controller: Ua ʻike piha ʻia ʻo PLC ʻo Programmable Logic Controller ma ka ʻōlelo Pelekania a me programmable logic controller ma ka ʻōlelo Kina.Ua wehewehe ʻia he ʻōnaehana uila e hana ʻia e nā hana kikohoʻe, i hoʻolālā ʻia no ka hoʻohana ʻana i nā wahi ʻoihana.Hoʻohana ʻo ia i kahi papa o ka hoʻomanaʻo programmable no ka mālama ʻana i nā papahana i loko, e hoʻokō ana i nā ʻōlelo aʻoaʻo e pili ana i ka mea hoʻohana e like me nā hana logical, sequential control, manawa, helu, a me nā hana helu, a me ka hoʻomalu ʻana i nā ʻano hana mechanical a i ʻole nā kaʻina hana ma o ke kikowaena a i ʻole analog.ʻO DCS Distributed Control System: ʻO ka inoa Pelekane piha o DCS he Distributed Control System, aʻo ka inoa Kina piha ʻo Distributed Control System.Hiki ke unuhi ʻia ʻo DCS ma ke ʻano he huahana ʻenehana kiʻekiʻe i hoʻohana nui ʻia i nā ʻoihana kahi i nui nā mana loop analog, e hōʻemi ana i nā pilikia i hana ʻia e ka mana, a me ka hoʻokele kikowaena a me nā hana hōʻike.ʻElima mau ʻāpana DCS: 1: mea hoʻoponopono 2: papa I/O 3: kahua hana 4: ʻuena kamaʻilio 5: nā kiʻi a me nā polokalamu hana.
1. Power module, e hāʻawi i ka mana hana i loko no ka hana PLC, a hiki i kekahi ke hāʻawi i ka mana no nā hōʻailona hoʻokomo.
2. ʻO ka module CPU, ʻo ia ka ʻāpana hana kikowaena o PLC, ʻo ia ke kumu o ka lako PLC.ʻO ka hana nui o PLC, e like me ka wikiwiki a me ka pālākiō, e hōʻike ʻia e kāna hana;
3. Hoʻomanaʻo: Mālama nui ia i nā polokalamu hoʻohana, a hāʻawi pū kekahi i ka hoʻomanaʻo hana hou no ka ʻōnaehana.Ma ke ʻano, pili ka hoʻomanaʻo i ka module CPU;
4. I / O module, ka mea e hoʻohui i nā kaʻa I / O a ua māheleʻia i nā modula o nā kiko'ī likeʻole e like me ka helu o nā helu a me keʻano kaapuni, me DI, DO, AI, AO, a pēlā aku;
5. Base plate a me rack module: Hāʻawi ia i kahi papa kumu no ka hoʻokomoʻana i nā modula PLC likeʻole, a hāʻawi i kahi kaʻa no ka pilina ma waena o nā modula.Ke hoʻohana nei kekahi mau backplanesnā modules interface a hoʻohana kekahi i nā kaʻa kaʻa e kamaʻilio me kekahi.ʻO nā mea hana likeʻole a iʻole nāʻano likeʻole o nā PLC mai ka mea hana hoʻokahiʻaʻole like;
6. Module kamaʻilio: Ma hope o ka hoʻopili ʻana i ka PLC, hiki iā ia ke hiki i ka PLC ke kamaʻilio me ke kamepiula, a i ʻole PLC e kamaʻilio me ka PLC.Hiki i kekahi ke hoʻokō i ke kamaʻilio ʻana me nā mea mana ʻē aʻe, e like me nā mea hoʻololi pinepine, nā mea mālama wela, a i ʻole e hana i kahi pūnaewele kūloko.Hōʻike ka module kamaʻilio i ka hiki ke hoʻopili pūnaewele o PLC a hōʻike i kahi mea koʻikoʻi o ka hana PLC i kēia lā;
7. Nā modula hana: ʻO ka mea maʻamau, aia nā modula helu helu kiʻekiʻe, nā modula mana kūlana, nā modula wela, nā modula PID, a me nā mea ʻē aʻe. .ʻOkoʻa loa nā ʻano a me nā ʻano o nā modula akamai.No nā PLC me ka hana maikaʻi, he nui nā ʻano o kēia mau modula a me ka hana maikaʻi.
