Ibyingenzi PLC Ubumenyi Kuri Gukora

Ibyingenzi PLC Ubumenyi Kuri Gukora

Mubice byumusaruro winganda niterambere ryikoranabuhanga, plcs (abagenzuzi ba porogaramu) bafite uruhare rukomeye muburyo bwo gukora. PLC irashobora kumvikana cyane nkinama yo kugenzura igenzura. Mubikorwa bifatika, PLC igabanya cyane ibiciro byinganda no kuzamura ibikoresho no kwitoza. Kuri Master PLC, umuntu agomba kubanza gusobanukirwa ubumenyi bwumuyobozi.

Ibigize PLC nibikorwa byabo

Usibye CPU, kwibuka, hamwe nimikoreshereze itumanaho, PLCs ifite ibitekerezo nibisohoka bifitanye isano itaziguye nimbuga zinganda.

1. Imigaragarire yinjiza: Yakira ibimenyetso kubikoresho bigenzurwa na disiki yimbere ukoresheje Optocouplers na Winjiza imirongo.

2. Imigaragarire yo gusohoka: Kohereza gahunda yo gusohoza ibisubizo binyuze kuri OptoCouplers nibice bisohoka (bijyanye, abakunzi, thepsostors) kugenzura imitwaro yo hanze.

Igice cyibanze cya PLC hamwe nibigize

Igice cyibanze cya PLC kigizwe nibice byinshi byingenzi:

1. CPU: Intangiriro ya PLC, kuyobora ibikorwa bitandukanye nko kwakira gahunda zabakoresha namakuru, kwisuzumisha, no gucwa na gahunda.

2. Kwibuka: Sisitemu ya sisitemu na gahunda zabakoresha namakuru.

3. I / o Ihuza PLC kubikoresho byinganda, kwakira ibimenyetso no gusohoka kubisubizo bya gahunda.

4. Imigaragarire itumanaho: Gushoboza guhana amakuru nibindi bikoresho nka bakurikirana na printer.

5. Amashanyarazi: Itanga imbaraga kuri sisitemu ya PLC.

Plc guhinduranya ibisohoka hamwe nibiranga

Plc guhinduranya ibisohoka:

1. Ubwoko bwa Thyristor Ubwoko: Mubisanzwe bikoreshwa hamwe na AC imizigo, irimo igisubizo cyihuse hamwe nintangarure zoherejwe.

2. Urutonde rwimyandikire Ubwoko: Mubisanzwe ikoreshwa hamwe na DC imitwaro, kandi itanga igisubizo cyihuse hamwe nintangarure zo gukora.

3. Uruhushya rwa relay Ubwoko: Bihuye na AC na DC imizigo, ariko hamwe nigihe kirekire cyo gusubiza hamwe nintangarugero yo hepfo.

Ubwoko bwa PLC hamwe nibiranga

PLC irashobora gushyirwa muburyo butandukanye bwimiterere:

1. Ubwoko bwingenzi: Hamwe na CPU, Amashanyarazi, na I / O Ibigize Ibigo byahujwe murubanza

2. Ubwoko bwa modular: ibiranga module zitandukanye kumikorere itandukanye, itanga iboneza byoroshye no kwaguka no kubungabunga. Mubisanzwe bikoreshwa muburyo buciriritse - kandi bunini - imiyoboro prcs kandi igizwe nikadiri cyangwa isahani shingiro na module zitandukanye.

3. Ubwoko bukomeye: Hagarika ibintu biranga ubwoko bwa pogral na modular. CPU, amashanyarazi, na I / o Interface ni module yigenga ihujwe nimigozi, kugirango iboneza byoroshye hamwe nubunini bwihuse.

Plc scan ukwezi ningaruka zayo

PLC Scan Inzoke ikubiyemo ibyiciro bitanu: Gutunganya imbere, Serivisi ishinzwe itumanaho, gutunganya ibitekerezo, kurangiza gahunda, no gutunganya ibisohoka. Igihe gisabwa kugirango urangize ibi byiciro bitanu bimaze kwitwa scan. Biterwa numuvuduko wa CPU, ibyuma bya PLC ibyuma, nuburebure bwa gahunda yumukoresha.

Plc uburyo bwo gukora gahunda nibikorwa

PLCs isohoza gahunda yumukoresha ukoresheje uburyo bwo gusikana. Inzira yo kwicwa irimo ibyiciro bitatu: kwinjiza icyiciro, kurangiza gahunda, no gusohoka kugarura.

Ibyiza byo kugenzura plc kuri sisitemu yo kugenzura relay

1. Uburyo bwo kugenzura: PLCS Koresha Igenzura ryateguwe, wemerera guhindura byoroshye cyangwa kuzamura ibisabwa kugenzura, hamwe numubano utagira imipaka.

2. Uburyo bwakazi: PLCS ikora muburyo bwumurongo, kuzamura gahunda ya sisitemu - Ubushobozi bwo kwivanga.

3. Kugenzura umuvuduko: Guhuza Plc ni imbaho zifatika hamwe nibihe byigisha byapimwe muri microseconds.

4. Igihe no kubara: PLCS Koresha ibice byumuziki uhuriweho nkibihe, hamwe namasaha ya oscillatos yatanzwe na Crystal Decstal Yatanzwe, atanga umwanya munini kandi ufite ubushobozi bwagutse. Bafite kandi kubara imirimo itaboneka muri sisitemu ya relay.

5. Kwizerwa no kubungabunga ubufasha: PLCS ikoreshwa tekinoroji ya microelecronics hamwe nibiranga - gukora imyitozo yo gusobanura neza gutahura mugihe.

Impamvu za PLC zisohoka igisubizo hamwe nibisubizo

PLCS ikoresha icyitegererezo cyo hejuru no gusohoka kclic scancing. Iyi status yinjiza irasomwa gusa mugihe cyinjiza cyashize kuri buri scan cycle, ibisubizo byo gushyira mubikorwa gahunda byoherejwe mugihe cyo kuvugurura icyiciro. Byongeye kandi, kwinjiza no gusohora gutinda hamwe nuburebure bwa gahunda yumukoresha burashobora gutera gusohoka. Kugirango wongere I / o Umuvuduko wo gusubiza, umuntu arashobora kongera inshuro yinjiza kandi asohotse kugarura ibitekerezo no gusohoka kugarura ibitekerezo no gusohoka, cyangwa gushyira mubikorwa ibitekerezo, cyangwa gushyira mubikorwa ubwenge I / o intera.

Imbere Yumuryango wimbere muri Siemens PLC

Siemens PLCs PLCS igaragara muburyo butandukanye bworoshye, harimo imyirondoro yinjiza, ibisohoka byerekeranye, imyirondoro ifasha, ibitabo bya status, ibitabo, kubara, hamwe na data.

Ibitekerezo byo gutoranya PLC

1. Guhitamo icyitegererezo: Reba ibintu nkibintu, uburyo bwo kwishyiriraho, ibisabwa byimikorere, umuvuduko wo gusubiza, kwizerwa, no guhuriza hamwe.

2. Guhitamo ubushobozi: Ukurikije I / O yerekana ubushobozi bwo kwibuka.

3. I / o Guhitamo Module: Gupfukaho Guhindura hamwe na Analog I / O Modules kimwe nibidasanzwe - imikorere.

4. Imbaraga zo gutanga amashanyarazi hamwe nibindi bikoresho Guhitamo: nkibikoresho byo gutangiza porogaramu.

Ibiranga plc tandukanya ibitekerezo no gusohoka muburyo bwakazi

Mu cyiciro cyo hejuru, imiterere yinjiza irateganijwe mugihe cyinjiza icyiciro cyo gutanga icyiciro cya scan, kandi ibyinjijwe irahagarikwa mugihe cyicyiciro cya gahunda. Mubisohoka byibanze, umusaruro wohereze icyiciro nigihe cyonyine mugihe urwego rwibisohoka rwimurirwa yimuriwe kumurongo wo kuvugurura interineti. Ubu buryo bukora butezimbere sisitemu yo kurwanya sisitemu no kwizerwa ariko birashobora gutera kwinjiza / gusohoka lag muri psccs.

PLC uburyo bwakazi nibiranga

PLCS ikora ukoresheje icyitegererezo cyinteganyanyigisho, ibisohoka hagati, no gusikana guclic. Icyitegererezo cyo hagati bisobanura imiterere yimiterere ni urugero mugihe cyinjiza icyiciro cyo gutangaza scan, hamwe nibikoresho byahagaritswe mugihe cyo kurangiza gahunda. Ibisohoka byibanze bivuga kohereza ibisohoka - Imiterere ijyanye nibisohoka Kwiyandikisha kubisohoka alch gusa mugihe cyo kuvugurura icyiciro cyo kuvugurura interineti. Gusikana bya cyclic bikubiyemo gukora ibikorwa byinshi murwego rwo gusikana mugihe - kugabana gusikana murukurikirane.

Ibigize no Gukora Ihame rya electromaGNETIC Contactors

Abahuza ba electromagnetic bagizwe nuburyo bwa electronagnetic, imibonano, ARC - Kwizihiza ibikoresho, kurekura uburyo bwisoko, hamwe nibigize. Iyo ibiceri bya electromagnetic bifite imbaraga, ubu byatangaga umurima wa rukuruzi, bigatuma Irn rihagaze kubyara kurekurwa hakiri kare gukurura armate kandi ikorana na contact. Ibi bituma mubisanzwe bifunze guhuza kugirango ufungure kandi mubisanzwe ufungure imibonano kugirango ufunge. Iyo coil ari de - ingwate, imbaraga zamato ya electromagnetic zirashira, kandi armature irekurwa nimpeshyi, kugarura imibonano kuri leta ya mbere.

Ibisobanuro bya logique yibitekerezo (plcs)

PLC nigikoresho cya elegitoroniki cyateguwe kubidukikije. Ikoresha ububiko bukoreshwa kugirango ubike amabwiriza yo gukora neza, ibikurikira, igihe, kubara, no kubara. Igenzura inzira zitandukanye cyangwa umusaruro binyuze muri digitale cyangwa analog yinjiza / ibisohoka.

PLC nibikoresho bifitanye isano na periphele byateguwe kugirango bihuze byoroshye na sisitemu yo kugenzura inganda no koroshya imikorere kwaguka.

Itandukaniro riri hagati ya PLC na Relay - Sisitemu ya TETSONI

Itandukaniro riri hagati ya PLC na relay - sisitemu ya transanganyo ikinyoma mubikoresho byabo bihimba, umubare wibiganiro, no kugenzura uburyo bwo gushyira mubikorwa.
