PLC tirohanga me te mara tono

Ko te kamupene te nuinga whakaputa AC contactor, iti iahiko breaker, kirihou taiepa ara iahiko breaker, mana rua pana aunoa, anga iahiko breaker, korehau ara iahiko breaker me ētahi atu hua.Ma Huatong nga tangata katoa e mohio ki te tirohanga whanui mo te PLC me te mara tono.

Kupu Whakataki

I roto i nga tau, kua mohio te kaiwhakahaere kaupapa (ka kiia ko te PLC) mai i tona whakatipuranga tae noa ki tenei wa, i te arorau hononga ki te mokowhiti arorau rokiroki;Ko tana mahi mai i te ngoikore ki te kaha, te mohio ki te ahunga whakamua o te mana arorau ki te mana mamati;Ko tana mara tono kua tipu mai i te iti ki te rahi, me te mohio ki te peke mai i te whakahaere ngawari o nga taputapu kotahi ki te mana whakahaere motini, te whakahaere tukanga me te whakahaere tohatoha me etahi atu mahi.Na PLC i roto i te tukatuka o te tairitenga, mahi mamati, atanga rorohiko tangata me te whatunga i roto i nga āhuatanga katoa o te kaha kua tino pai ake, hei te taputapu mana auraki i roto i te mara o te mana ahumahi, i roto i nga hīkoi katoa o te ora kei te takaro i te ake me te ake tūranga nui.

Ko te waahanga tono a PLC

I tenei wa, kua whakamahia nuitia te PLC i roto i te rino me te rino, te hinu, te ahumahi matū, te hiko hiko, te hanga whare, te hanga miihini, te motuka, te kakano, te kawe waka, te tiaki i te taiao me te whakangahau ahurea me etahi atu ahumahi, ko te whakamahinga o nga waahanga matua ko te e whai ake nei:
1. Whakawhiti te mana arorau rahinga

Whakakapihia te ara iahiko relay tuku iho, mohio ki te mana arorau, mana raupapa, ka taea te whakamahi mo te mana taputapu kotahi, ka taea hoki te whakamahi mo te whakahaere roopu miihini maha me te raina huihuinga aunoa.Pērā i te mīhini werohanga, te mīhini tā, te mīhini tā, te taputapu mīhini whakakotahi, te mīhini huri, te raina whakaputa tākai, te raina hiko me te aha atu.

2. Whakahaere tukanga ahumahi

I roto i te tukanga o te hanga ahumahi, kei reira etahi penei i te pāmahana, te pehanga, te rere, te taumata wai me te tere me etahi atu huringa tonu (arā, te nui o te whaihanga), ka whakamahia e te PLC te waahanga whakawhiti A / D me te D / A me te A momo o te mana hātepe hōtaka ki te mahi ki te nui o te whaihanga, oti te mana koropiko kati.Ko te mana PID he momo tikanga whakahaere e whakamahia nuitia ana i roto i te punaha whakahaere katia.Ko te whakahaere o te tukanga e whakamahia nuitia ana i roto i te whakarewatanga, te ahumahi matū, te maimoatanga wera, te whakahaere paera me etahi atu waa.

3. Te whakahaere nekehanga

Ka taea te whakamahi i te PLC mo te whakahaere i te nekehanga porohita, te nekehanga raina ranei.Te whakamahi whānui o te kōwae mana nekehanga motuhake, pērā i taea te pei i te nekeneke stepper nekeneke servo kotahi-tuaka ranei maha-tuaka tūnga kōwae mana, whānui whakamahia i roto i te momo o mihini, taputapu mihini, lōpoti, elevators me ētahi atu wā.

4. Ko te tukatuka raraunga

Kei te PLC te mahi pangarau (tae atu ki te mahi matrix, te mahi mahi, te mahi arorau), te whakawhiti raraunga, te whakawhiti raraunga, te tohatoha, te titiro tepu, te mahi moka me etahi atu mahi, ka taea te whakaoti i te kohinga raraunga, te tātari me te tukatuka.Ko te tukatuka raraunga ka whakamahia i roto i nga punaha whakahaere nui i roto i nga umanga penei i te pepa, te whakarewa me te kai.

5. Whakawhitiwhiti me te Whatunga

Ko te whakawhitinga korero a te PLC ko te whakawhitinga korero i waenganui i te PLC me te whakawhitiwhiti i waenga i te PLC me etahi atu taputapu mohio.Na te whanaketanga o te whatunga aunoa wheketere, he atanga korero a PLC inaianei, he tino watea te korero.
