Chidziwitso chofunikira cha plc pachokha

Mu malo opanga mafakitale ndi kupita patsogolo kwaukadaulo, olamulira mapulogalamu a PLCS (Pulogalamu Yothandizira)) PLC imatha kumvetsetsa bwino ngati gulu lowongolera lapakatikati. Pamapulogalamu othandiza, ma plcs amachepetsa kwambiri mtengo wowongolera mafakitale ndikuwonjezera manangano ndi zida zamagetsi ndi zochita. Kwa Master PLCS, imodzi iyenera kumvetsetsa kaye chidziwitso cha maziko.

Zida za PLC ndi ntchito zawo

Kuphatikiza pa CPU, Memory, ndi kulumikizana kwa macheza, ma PLC ali ndi kulowetsana ndikutulutsa mapangidwe okhudzana ndi mafakitale.

1. Makina ogwiritsira ntchito: amalandila zizindikiro kuchokera pazomwe zimayendetsedwa ndi mabwalo apakati apa ma Oprocouprers ndi mabwalo otsegulira.

2. Makina odzola: Amatumizira zotsatira za pulogalamu ya pulogalamu kudzera pa oppoocouprers ndi zigawo zotulutsa (zachinsinsi, altristors, otumiza) kuti azilamulira katundu wakunja.

Chigawo cha PLC ndi zigawo zake

Chipinda choyambirira cha PLC chili ndi zigawo zingapo zazikulu:

1. CPU: Pakati pa PLC, kuwongolera ntchito zosiyanasiyana monga kulandira mafilimu ndi deta, diagnostics, kuphedwa.

2. Memory: Imasunga dongosolo ndi mapulogalamu a ogwiritsa ntchito ndi deta.

3. I / O unione: imalumikiza za PLC ku zida za mafakitale, kulandira zizindikiro ndi zotsatira zoyipa.

4. Kulumikizidwa: kumathandiza kusinthana kwa chidziwitso ndi zida zina ngati oyang'anira ndi osindikiza.

5. Magetsi: Amapereka mphamvu ku PLC.

PLC Kusasintha mawonekedwe otulutsa ndi mawonekedwe awo

PLC Kutembenuza Kuphatikizira kwa Plc:

1. Mtundu wa Tyritur: zomwe zimagwiritsidwa ntchito ndi katundu wa ac, zomwe zimagwira ntchito mwachangu komanso pafupipafupi.

2. Mtundu wa Transistor: Nthawi zambiri amagwiritsidwa ntchito ndi katundu wa DC, nawonso amaperekanso yankho komanso pafupipafupi.

3. Mtundu wolumikizirana: wogwirizana ndi ma acs onse a AC ndi DC, koma ndi nthawi yoyankha komanso yotsika.

Mitundu ya plc yopanga ndi mawonekedwe awo

Ma PLCS amatha kugawidwa m'magulu atatu:

1. Mtundu wophatikizidwa: ndi CPU, magetsi, ndi ine / o / o / o / o / o / mtundu wake ndi wothandiza - wogwira mtima - wogwiritsidwa ntchito kwambiri - womwe umagwiritsidwa ntchito kwambiri.

2. Mtundu wamtundu: mawonekedwe osiyana ndi ma module a ntchito zosiyanasiyana, kupereka masinthidwe osinthika komanso kukula kosavuta ndi kukonza. Nthawi zambiri imagwiritsidwa ntchito pakatikati - komanso yayikulu - yokhazikika ndipo imakhala ndi chimango kapena ma module osiyanasiyana.

3. Mtundu wokhazikika: kuphatikiza mawonekedwe a mitundu yophatikiza komanso yolunjika. CPU, magetsi, ndi ine / o Interfaces ndi ma module odziyimira pawokha omwe amalumikizidwa ndi mabatani, onetsetsani kuti masinthidwe osinthika komanso kukula kwakukulu.

Chuma cha Plc Scan ndi zomwe zimapangitsa zinthu

Kuzungulira kwa PLC Scan ku Scan Scenems Sensepoms: Kufufuza kwamkati, Kulumikizana, kukonzanso, kukonza njira, pulogalamu yogulitsa, ndi kukonza. Nthawi yofunikira kumaliza magawo asanuwa kamodzi amatchedwa kuzungulira kwa scan. Imakhudzidwa ndi liwiro la CPU, kusintha kwa Plc Hardware, ndi kutalika kwa pulogalamu yogwiritsa ntchito.

Njira Yodzipha ndi Njira

Plcs imapereka mapulogalamu ogwiritsa ntchito pogwiritsa ntchito njira ya cyclic. Njira yophedwa imaphatikizira magawo atatu: kukonza zitsanzo, pulogalamu yophedwa, ndi kutsitsimula.

Ubwino wa Maulendo Olamulira a Plc panjira yoyang'anira

1. Kuwongolera Njira: Ma PLS amagwiritsa ntchito njira yowongolera, kulola kusanza kapena kupititsa patsogolo kudziletsa, popanda malire.

2. Kugwiritsa Ntchito Mode: PLCS imagwira ntchito mu seri ya seri, yolimbitsa dongosolo la dongosolo - kusokonekera.

3. Kuthamanga Kuthamanga: Mabwenzi a Plc amachititsa chidwi ndi nthawi zofunsidwa zomwe zimayesedwa mu microsecond.

4. Nthawi ndi kuwerengera: PLCS Gwiritsani ntchito semiconduct yophatikizira madera ophatikizika, ndi ma pitani omwe amaperekedwa ndi ma shristillato oscillators, kupereka nthawi yokwanira komanso yovuta kwambiri. Amakhala nawonso kuwerengera ndalama sikupezeka munjira zonse.

5. Kudalirika komanso kusuntha: PLCS Gwiritsani ntchito ukadaulo wa Microelectronics ndikudzipangitsa kuti ukhale wodetsa nkhawa za nthawi yake.

Zomwe zimayambitsa mayankho a PLC yotulutsa ndi mayankho

PLCS imagwiritsa ntchito zitsanzo zapakati ndi kutulutsa kwa cyclic. Zithunzi zolowetsa zimangowerengedwa panthawi yolowetsa katatu ka scan iliyonse, ndipo zotsatira za pulogalamuyi zimangotumizidwa nthawi yotulutsa zolimbitsa thupi. Kuphatikiza apo, kulowetsedwa ndi kuwonongeka kwa mabulosi ndi kutalika kwa pulogalamu ya ogwiritsa ntchito kumatha kuyambitsa mayankho. Kupititsa patsogolo i / O Kuyankha mwachangu, wina amatha kuwonjezera pafupipafupi zitsanzo za kusinthasintha ndi kutulutsa mwachindunji, kugwiritsa ntchito njira yosinthira, kapena kukhazikitsa anzeru.

Chilankhulo cha mkati mwa siemens plc mndandanda

SIEMENES imayanjana kwambiri, kuphatikizapo zopereka, kuphatikizaponso kusunganso, kugwiritsa ntchito ma rebiciary, mikhalidwe, nthawi, zowerengera, ndi restication.

Maganizo a PLC

1. Kusankhidwa kwachitsanzo: Onani zinthu monga kapangidwe kake, njira yokhazikitsa, zofunikira zogwira ntchito, liwiro, kudalirika, komanso kufanana.

2. Kusankha kwa mphamvu: Kutengera i / O mfundo ndi ogwiritsa ntchito kukumbukira.

3. I / O Kusankha: kumakwirira kusintha ndi analog i / O ma module komanso ma module a ntchito.

4. Module yamagetsi ndi kusankhana wina: monga zida za mapu.

Makhalidwe a PLC Centerved Sypling ndi Makina Ogwira Ntchito

Pakatikati, mawonekedwe osokoneza amasankhidwa pokhapokha gawo lolowera la scan loyambira, ndipo mathero ake amatsekedwa panthawi yomwe pulogalamu yakupha idaphedwa. Potulutsa chapakati, gawo lokhalo loti likhale lokhalo ndi nthawi yokhayo yomwe ikakhala kuti ikuwonetsa kuti itulutsidwe imasinthitsa ku zotulukapo zokolola. Makina ogwirira ntchito awa amathandizira madongosolo a dongosolo - kugwirira ntchito komanso kudalirika koma kungayambitse kuyankha / kubweretsa mayankho mu PLCS.

Makina a Plc ndi mawonekedwe

Ma PLCS amagwira ntchito pogwiritsa ntchito zitsanzo zapakatikati, zotuluka zapakati, ndi ma cyclic. Ma Sampling Aelengs amatanthauza kuti mawonekedwe amagawidwa pokhapokha gawo loyambira la scan gawo la scan, lomwe limatha cholowa chomwe chatsekedwa panthawi yopulumutsa pulogalamu. Zotsatira zapakati zimatanthawuza kutulutsa kwa kutulutsa - mawonekedwe okhudzana ndi chithunzi cha kubweretsa ku Register gawo pokhapokha potsitsimutsa. Cyclic Scanurning imaphatikizapo kuyendetsa ntchito zingapo mu concled nthawi yayitali kudutsa nthawi - gawani yogawana.

Kuphatikizika ndi mfundo ya mapangidwe a elemabognetic

Ma discommaromagnetic amakhala ndi zamagetsi zamagetsi, kulumikizana, marc - zida zozimitsidwa, zimatulutsa njira zamasika, zimatulutsa zikhalidwe zamasika, ndikuyika zigawo zina. Pamene coil yamagetsi ikapatsidwa mphamvu, imatulutsa maginito, ndikupangitsa kuti chitsulo chamagetsi chopanga ma elekitromagnagnagmat omwe amakopa madama ndikuwacheza nawo. Izi zimayambitsa kulumikizana ndi olumikizana kuti titsegule ndipo nthawi zambiri amalumikizana. Chovala chikakhala ndi chopatsa mphamvu, mphamvu yamagetsi imatha, ndipo zida zankhondo zimatulutsidwa ndi kasupe, kubwezeretsa kulumikizana kwawo.

Tanthauzo la Olamulira Olamulira Olowera (PLCS)

PLC ndi chipangizo chamagetsi chamagetsi chopangidwa m'malo opangira mafakitale. Imagwiritsa ntchito kukumbukira malangizo kuti asunge malangizo ochitira zinthu, zotsatizana, nthawi, kuwerengera, komanso masamu. Imayendetsa njira zosiyanasiyana kapena zopangira kudzera mu digito kapena analog kulowetsa / zotulutsa.

Zipangizo zokhudzana ndi PLCS ndi zofananira zimapangidwa kuti ziziphatikizana mosavuta ndi makina owongolera mafakitale ndikuthandizira kukulitsa mphamvu.

Kusiyana pakati pa PLC ndi kubwereza - Makina Othandizira

Kusiyana pakati pa Plc ndi Phokoso - Makina ogwirizanitsa amagona pazida zawo, kuchuluka kwa olumikizana, ndi njira zowongolera.
