Taua le malamalama mo otometi

Taua le malamalama mo otometi

I le Mentia o Alamanuia gaosiga ma le tekonolosi agai i luma, pccs (polokalame (polokalama custic custorers) e taua se tiute taua i le puleaina o le otometi. O le plc e mafai ona malamalama lautele o se faʻavae faʻavae faʻatulagaina o le faʻaaogaina o le faʻatulagaina. I tulaga aoga, e matua faʻaititia i lea galuega ma e faʻalautele meafaigaluega masini ma aʻoaʻoga. I le Master Plcs, o le tasi e tatau ona malamalama muamua i le malamalamaaga.

Pluc vaega ma a latou galuega

I le faaopoopo atu i le CPU, manatua, ma fesoʻotaʻiga i taimi uma, o le PLCS e i ai i galuega faatino ma e mafai ona taofia e le vaega gaosi oloa.

1. Intoput Interface: Mauaina faailoilo mai masini faʻatonutonu ma aveina i totonu o nofoaga i totonu e ala i le optocopoplers ma faʻamatalaga faʻapipiʻi.

2. Galuega Faʻatulagaina: Faʻaliliuina Polokalame Faʻamalieina e ala i le OPtocopuplers (faʻamatalaga, Thersistors, o tagata valaʻaulia) e pulea ai uta i fafo atu.

Faavae plc iunite ma ona vaega

O le vaega autu e aofia ai ni vaega taua:

1. CPU: O le autu o le plc, faʻatonutonu eseese gaioiga e pei o le mauaina o polokalame faʻaaoga ma faʻamaumauga, faʻailoga, ma polokalame.

2. Manatua: Faleoloa Polokalama ma Tagata Faʻaaoga polokalame ma faʻamaumauga.

3. I / O Punavai: Faʻafesoʻotaʻi le PLC i Alamanuia mea faigaluega, mauaina o faʻailoga ma faʻamatalaga oloa.

4. Fesootaiga Polofesa: Faʻamaloloina faʻamatalaga fesuiaiga ma isi masini e pei o siaki ma aliʻi.

5. Malosiaga sapalai: saunia le mana i le plc system.

Plc fesuiai mai i fafo o mea totino ma o latou uiga

Plc Suiga o oloa i fafo:

1. Tyristar Intutturt Type: masani ona faʻaaogaina ma ac avega, o le faʻaalia vave tali ma maualuga faʻagaioiga faʻafia.

2. Transistor Wipement Type: E masani ona faʻaaogaina ma le DC avega, na maua ai foi le tali vave ma le maualuga o le tali ma le maualuga o taimi.

3. O le faʻamatalaga o loʻo i ai le faʻamatalaga: faʻafetaui ma le AC ma le DC uta, ae o le umi le tali vave ma le faʻagaioiga maualalo.

PLC tulaga fausaga ma o latou foliga

O le plcs e mafai ona faʻavasegaina i totonu o le tolu ituaiga o ituaiga:

1. Tuʻuina atu ituaiga: ma CPU, Malosiaga eletise, ma o aʻu / O vaega o loʻo nonofo i se tasi mataupu, o lenei ituaiga e fetaui lelei ma le tau - aoga precs.

2. Modular Type: Foliga eseese mo galuega eseese, ofoina fetuʻu fetuutuunai fetuunai ma faigofie faʻalauteleina ma le tausiga. E masani ona faʻaaogaina i le auala-ma tele - Fua o le Filcs ma e aofia ai le faʻavaʻa poʻo le pito i lalo ipu ma eseese modules.

3. Faʻapipiʻi ituaiga: tuʻufaʻatasiga o foliga o le tuʻufaʻatasia ma modular ituaiga. O le CPU, sapalai eletise, ma o aʻu / o faʻamatalaga o loʻo sosoʻo mai modules faʻafesoʻotaʻi e le uaea, mautinoa o fetuutuunai fetuutuunai ma le tele o le fetuutuunai.

Pluc scan smic ma o mea taua

O le PLC Scan Smic e aofia ai tulaga e lima: faiga i totonu, Fesootaiga fesoʻotaʻiga, faiga faʻatino, polokalama faʻatinoga, ma galuega faʻatino. O le taimi e manaʻomia e faʻamaeʻa ai nei vaega e lima o loʻo manatu o le faʻasolo i le taamilosaga. O loʻo aʻafia i le saoasaoa o le CPU, plc starware spedigration, ma le umi o le tagata faʻaaoga polokalama.

Plc polokalame polokalame faʻatino metotia ma faʻagasologa

Plcs o loʻo faʻatinoina polokalame faʻaaoga e faʻaaoga ai le cyclic scaling metotia. O le gaioiga faʻataunuʻu aofia ai vaega e tolu: tau faʻavave, o le polokalama, ma le faʻatinoga o galuega faʻatino.

Tulaga lelei o le PLC Pulea polokalama i luga o le Repy Pusa Polokalama

1. Puleaina o Metotia: Plcs faʻaaogaina polokalama faʻatonutonu, faʻatagaina faigofie le faʻaleleia o le faʻatonutonuina poʻo le faʻaleleia o le faʻatonutonu manaʻoga, ma fesoʻotaʻiga faʻatapulaʻaina.

2. Galue Mode: PLCS faagaoioia i se faʻasologa o le faasologa, faʻaleleia le anti o le anti - faʻalavelavea.

3. Pulea le saoasaoa: PLC fesootaiga o loʻo i ai le sili ona faʻamalosia i le faʻatonuga o taimi na fuaina i Microseconds.

4. Taimi ma le faitauina o: PLCS faʻaaogaina semicoundouctor tuʻufaʻatasia croutits o taimi, ma le uati o loʻo puʻeina e cyststal taimi. E le mafai foi ona iai ni galuega mo teuga polokalame.

5. Faʻatuatuaina ma le teuina i le tino: PLCS e faʻaaoga ai le Microde Degliel Degy Deglies ma Expnostic galuega mo le taimi na iloa ai

Mafuaaga o le plc galuega talitata tali ma fofo

Plcs faafaigaluega i le ogatotonu o le faʻataʻitaʻi ma le cytput cyclic scansing. O le Innet State e na o le faitauina i le taimi o le Intut Samplings vaega o togi taʻitasi proycle, ma le polokalama faʻatino iuga faʻaiuga e naʻo le faʻaumaina. E le gata i lea, sao ma galuega faafaigaluegaina ma o le tagata faigaluega polokalame e mafai ona mafua ai le tali atu i le galuega. Ina ia faʻaleleia aʻu / O le tali saoasaoa, tasi e mafai ona faʻateleina ai le faʻaaogaina o le faʻaaogaina o le faʻaaogaina ma le faʻaaogaina o le faʻaaogaina o le faʻaaogaina o le faʻasoasoaina ma le faʻaaogaina.

Nofoaga i totonu

O Slaimens Plcs faʻaalia ai ni mea vaivai i totonu, e aofia ai faʻamatalaga i mea sao, sapalai o tupe sao, faʻamatalaga taua, tulaga, ma tusi resitala.

Plc filifiliga filifiliga

1. Faʻataʻitaʻiga Filifilia: Mafaufau i itu e pei o le fausaga, faʻapipiʻi metotia, faʻaaoga manaʻoga, tali vave, tali atu, ma le mataʻitu.

2. O le malosi filifilia: faʻavae i luga o aʻu / O manatu ma le faʻaaogaina o le mafaufau.

3. Ou / o Module Filifiliga: Cover Talivali ma AALALY I / O MODEYSE AOAO ATU O LE FAIGALUEGA - GALUEGA MODEL.

4. Mana sapalai module ma isi masini filifilia: pei o masini faaagafemi.

Uiga o le plc totonugalemu samplings ma galuega faatino galuega

I totonu o le ogatotonu o le faʻataʻitaʻiga, o loʻo i ai le tulaga o loʻo i ai i le taimi o le faʻaaogaina o le faʻataʻitaʻiga o le taamilosaga o le scacle, ma o le mea e oʻo ai o loʻo poloka i le taimi o le polokalama. I totonu o le faʻatulagaina o galuega, o le oloa faʻatulagaina e toe faʻafouina le taimi ua maeʻa ai le tulaga i le folasaga o loʻo lisiti atu. O lenei faiga galue e faʻaleleia atili ai le stictic anti - faʻalavelaveina le mafai gafatia ma le talitonuina ae ono mafua ai ona mafua ai le faʻamatalaga / itput.

PLC galue faiga ma foliga

PLCS faʻagaioia faʻaaogaina o le faʻatulagaina o le faʻataʻitaʻi, tutotonu o galuega, ma cyclic scanking. O le ogatotonu o le faʻatulagaina o lona uiga o le faʻaaogaina o le faʻaaogaina o le faʻaaogaina o le faʻaaogaina o le vaega o le vaʻai o le taamilosaga o le taamilosaga, ma le sao o loʻo taofia i le taimi o le polokalama. Faʻatulagaina Tautala faʻasino i le faʻaliliuina o galuega faʻatino - tulaga faʻatatau mai le faʻamaumauga o loʻo faʻaaogaina i le UPS o loʻo loka na o le faʻaaogaina o le galuega. O le Cyclic Scanning aofia ai le faʻatinoina o le tele o galuega i se suʻega taamilosaga i le taimi - vaevaega vaʻai i le faʻasologa.

Tuʻufaʻatasiga ma le faʻaaogaina o le eletise eletise eletise

E aofia ai i tagata electromagnetic ni masini eletise, fesootaiga, fesoʻotaʻiga, arc - tipitipi masini, faasaoloto o fetuutuunai. A taitaiina o le electromagigac i le taimi nei, o le taimi nei e faia ai se maneta fanua, mafua ai le le tumau o le unronicanic octonetic e tosina mai ai le au electromonic O lenei mafuaʻaga e masani ona tapunia fesoʻotaʻiga e tatala ma masani ai faʻafesoʻotaʻi faʻafesoʻotaʻi e tapunia. A o le COIL o le de - faʻamalosi, o le eletise eletise e mou ese atu, ma o le armature ua tatalaina e le tautotogo, toe faʻaleleia le fesoʻotaʻiga i la latou tulaga muamua.

Faʻauiga o le Faʻauiga Faʻapitoa Custic Runllers (Plcs)

O le plc o se numera numera eletise na fuafuaina mo alamanuia siosiomaga. E faʻaaogaina se polokalame faʻatonutonuina e teu ai faʻatonuga mo le faʻatinoina o mea talafeagai, seneve, sailiga, faitauina, ma le numera numera. E faʻatonutonuina le tele o masini poʻo le gaosiga o gaioiga e ala i le numera poʻo le asoa faʻamatalaga / oloa.

O le plcs ma e fesoʻotaʻi ma mea e faʻasino i le pripheal o loʻo fuafuaina e faigofie ona tuʻufaʻatasia ma le faʻatonutonuina o gaioiga ma faʻafaigofie gaioiga faʻagaioiga.

Eseesega i le va o le PLC ma le Regon - Fesootaiga faiga

O le eseesega i le va o le Plc ma faʻamatalaga - O fesoʻotaʻiga fesoʻotaʻiga e taoto i a latou faigamalo, numera o fesoʻotaʻiga, ma le puleaina o metotia faʻatino.
