Nigute PLC yashyizwe mubikorwa? Ni ibihe bipimo by'ingenzi byerekana imikorere?
Nigute PLC yashyizwe mubikorwa? Ni ibihe bipimo by'ingenzi byerekana imikorere?
PLC irashobora gushyirwa mubyiciro muburyo bukurikira:
Ukurikije Imiterere:
Integral PLC (cyangwa Unitar PLC): Ibigize byose, harimo amashanyarazi, CPU, na I / O, byinjijwe mumazu umwe.
Modular ya PLC (cyangwa Yegeranye PLC): Ibigize nka module yo gutanga amashanyarazi, module ya CPU, na I / O module yubatswe yigenga. Ibi birashobora guhurizwa kumurongo uhamye cyangwa kumurongo ushingiye kubisabwa byihariye kugirango ukore sisitemu yuzuye ya PLC.
Kubushobozi bwa I / O Ingingo:
PLC yuzuye: Mubisanzwe ufite amanota ari munsi ya 256 I / O, nka Siemens S7-200SMART PLC.
Hagati ya PLCs: Koresha imiterere ya modular kandi muri rusange ufite amanota I / O kuva kuri 256 kugeza 1024, nka Siemens S7-300 PLC.
PLC nini: Mubisanzwe ufite amanota arenga 1024 I / O, nka Siemens S7-400 PLC.
Ibipimo byingenzi byerekana imikorere ya PLC:
Mugihe PLCs ziva mubikorwa bitandukanye zishobora gutandukana mubiranga, basangiye ibipimo byinshi bisanzwe:
Iyinjiza / Ibisohoka (I / O) Ingingo: I / O amanota yerekana umubare winjiza hanze nibisohoka ibyambu bihujwe kumwanya wa PLC. Ingingo nyinshi I / O zirahari, nubushobozi bwo kugenzura PLC ifite. Iki nikimwe mubintu bikomeye cyane muguhitamo PLC.
Umuvuduko wo Gusikana: Iyi metric yerekana uburyo PLC ikora byihuse gahunda yayo. Mubisanzwe bipimwa muri milisegonda isabwa kugirango ukore amabwiriza ya 1K.
Ubushobozi bwo kubika: Ubushobozi bwo kubika bukunze kugaragara mubijyanye na kilowords (KW), kilobytes (KB), cyangwa kilobits (Kbit), aho 1K = 1024. PLC zimwe zitanga ububiko bwagutse.
Amabwiriza: Amabwiriza yerekana imbaraga zerekana imikorere ya software ya PLC. Amabwiriza akungahaye asobanura imbaraga zikomeye zo gutangiza gahunda.
Kwiyandikisha imbere (Relays): PLCs irimo rejisitiri nyinshi zo kubika impinduka, ibisubizo hagati, hamwe namakuru. Iboneza ryibi bitabo nabyo byerekana imikorere ya PLC.
Ubushobozi bwo Kwaguka: Ibi birerekana uburyo PLC ishobora guhuza module yinyongera kumirimo yihariye, nka A / D, D / A, kubara byihuse, cyangwa kure y'itumanaho rya kure.
Kugereranya Hagati ya PLC na Sisitemu yo Kugenzura:
Mbere yuko haza PLCs, relay inzitizi zikomeye zari uburyo bwambere bwo kugenzura byumvikana kandi bikurikiranye. Byari byoroshye kandi bihendutse ariko ntibibuze guhinduka. Kuva hashyirwaho PLCs, hafi buri kintu cyose cyimikorere yabo cyarenze icya sisitemu yo kugenzura relay.
Imigendekere yiterambere rya PLCs:
Kwimukira mubikorwa byo hejuru, gutunganya byihuse, nubushobozi bunini.
Gutezimbere imiyoboro hamwe nubushobozi bwitumanaho.
Guhinduka muto, bikoresha amafaranga menshi, kandi byoroshye gukoresha.
Gukomeza kunoza imikorere ya software.
Gutezimbere module nshya igenewe porogaramu ya PLC.
Gutezimbere miniaturizasiya hamwe na software ishingiye ku bwihindurize bwa PLC.
