Ibikoresho bya NPN na PNP na Siemens PLC Guhuza no Guhitamo

Sensors irashobora gushyirwa mubwoko bubiri bwingenzi ukurikije ubwoko bwibisohoka: NPN (izwi kandi nkisoko - ubwoko bwa sensor) na PNP (bizwi kandi nka sink - ubwoko bwa sensor). Ubwoko bwombi bwa sensor zifite kuyobora bitatu, bihujwe na 24V, 0V, na Out (ibisohoka byerekana). None, ni ubuhe bwoko bwa sensor zishyigikiwe na Siemens S7 ikurikirana ya PLC?

Ubwoko bwa Sensors Bishyigikiwe na Siemens PLCs na Modules

Sensors Yashyigikiwe na Siemens S7 - 200: Isohora ryinjira rya seriveri ya S7 - 200 ishyigikira inkomoko - ubwoko na sink - ubwoko bwa sensor, bivuze ko bishobora guhuzwa na sensor ya NPN cyangwa PNP.

Sensors Gushyigikirwa na Siemens S7 - 200smart: Bisa na S7 - 200, S7 - 200smart yinjiza yinjiza ishyigikira ibyuma byombi - ubwoko ninkomoko - ubwoko bwa sensor, byemerera guhuza ibyuma byombi bya NPN na PNP.

Sensors Gushyigikirwa na Siemens S7 - 1200: S7 - 1200 yinjizamo ibyinjira byunganira byombi sink - ubwoko ninkomoko - ubwoko bwa sensor, bigafasha guhuza ibyuma bya NPN cyangwa PNP.

Sensors Yashyigikiwe na Siemens S7 - 300: S7 - 300 ifite modul zitandukanye za DI, kandi ubwoko bwa sensor bashyigikira bugomba kugenzurwa muburyo bwibikoresho bishingiye kubipimo.

Hafi ya DI modules ya S7 - 300 irarohama - ubwoko (sensor ya PNP igomba gutoranywa): Muburyo bwibikoresho, ntihaboneka ikibazo cyinkomoko cyangwa ubwoko bwa sink, bivuze ko byanze bikunze kurohama - ubwoko. Kurugero, module 321 - 1BL00.

Inkomoko - andika DI module ya S7 - 300 (sensor ya NPN igomba guhitamo): Kurugero, 6ES7 321 - 1BH50 - 0AA0 module.

Universal DI module ishyigikira ubwoko bwinkomoko nubwoko bwose (ibyuma byombi bya NPN na PNP birashobora gukoreshwa): Kurugero, 6ES7 321 - 1BP00 - 0AA0 module.

Sensors Yashyigikiwe na Siemens S7 - 1500: Module ya DI iboneka muri seriveri ya S7 - 1500 harimo sink - ubwoko bwa modules zishyigikira ibyuma bya PNP ninkomoko - ubwoko bwubwoko bushyigikira sensor ya NPN.

Kurohama - andika DI modules (sensor ya PNP): Kurugero, 6ES7 523 - 1BL00 - 0AA0 module.

Inkomoko - andika DI modules (sensor ya NPN): Kurugero, 6ES7 131 - 6BF60 - 0AA0 module.

Uburyo bwo Gukoresha Uburyo bwa NPN na PNP

Gusobanukirwa Iyinjiza rya Terminal Ubwoko bwa PLCs: Ibisobanuro byinkomoko - ubwoko na sink - ubwoko bwa Siemens PLC ibyinjira byinjira bishingiye ku cyerekezo cyogutemba kuri I - point ya terminal ya PLC. .

Inkomoko - ubwoko: Iyo ikigezweho kiva muri I - ingingo, ifatwa nkinkomoko yubu.

Kurohama - ubwoko: Iyo ikigezweho gitemba muri I - ingingo, ifatwa nkaho igana ikigezweho.

Guhuza ibyumviro bya NPN kuri PLC (Inkomoko - andika Iyinjiza rya Siemens PLC): Urujya n'uruza: 24V + → COM terminal → I0.0 (ibiva hanze biva I - point) → sensor out terminal → sensor 0V terminal → 0V.

Guhuza ibyumviro bya PNP kuri PLC (Sink - andika Iyinjiza rya Siemens PLC): Urujya n'uruza: 24V + → sensor 24V → sensor out terminal → I0.0 (ibyinjira muri I - point) → COM → 0V.

Ibyiciro bya Sensors

NPN (Inkomoko - ubwoko): Iyo ikora, isohora ikimenyetso cyo hasi - urwego.

NPN - OYA (Mubisanzwe Gufungura): Nta bisohoka iyo bidakozwe; isohora ikimenyetso cyo hasi - urwego iyo rukora.

NPN - NC (Mubisanzwe bifunze): Ibisohoka ikimenyetso cyo hasi - urwego iyo kidakozwe; nta bisohoka iyo byakozwe.

NPN - NC + OYA (Bihujwe Mubisanzwe Gufungura kandi Bisanzwe Bifunze): Ibisohoka bibiri bisohoka (kimwe gifungura, kimwe gifunze).

PNP (Kurohama - ubwoko): Iyo ikora, isohora ikimenyetso cyo hejuru - urwego.

PNP - OYA (Mubisanzwe Gufungura): Nta bisohoka iyo bidakozwe; Ibisohoka hejuru - urwego rwohejuru iyo rukora.

PNP - NC (Bisanzwely Gufunga): Ibisohoka hejuru - urwego rwohejuru iyo rudakozwe; nta bisohoka iyo byakozwe.

PNP - NC + OYA (Bihujwe Mubisanzwe Gufungura kandi Bisanzwe Bifunze): Ibisohoka bibiri bisohoka (kimwe gifungura, kimwe gifunze).

Itandukaniro ryibanze hagati ya PNP na NPN Sensors

Ibyuma bya PNP na NPN byombi birahinduka - ubwoko bwa sensor ikoresha kwiyuzuzamo no kugabanya transistors kugirango isohore leta ebyiri. Nyamara, ibimenyetso bisohoka biratandukanye: NPN isohora ikimenyetso cyo hasi - urwego (0V), mugihe PNP isohora ikimenyetso cyo hejuru (24V).

Ibyuma bya PNP na NPN byashyizwe mubice bitandatu:

NPN - OYA (Mubisanzwe Gufungura)

NPN - NC (Mubisanzwe bifunze)

NPN - NC + OYA (Bihujwe Mubisanzwe Gufungura kandi Bisanzwe Bifunze)

PNP - OYA (Mubisanzwe Gufungura)

PNP - NC (Mubisanzwe bifunze)

PNP - NC + OYA (Bihujwe Mubisanzwe Gufungura kandi Bisanzwe Bifunze)

Ibyuma bya PNP na NPN mubisanzwe bifite inzira eshatu: umurongo utanga amashanyarazi (VCC), umurongo wa 0V, n'umurongo wo gusohora ibimenyetso.

Ubwoko bwa PNP: Iyo buteruwe, umurongo wo hanze uhuza umurongo w'amashanyarazi (VCC), ugatanga ikimenyetso cyo hejuru - urwego.

PNP - OYA: Umurongo wo hanze urakinguye (uciwe na VCC) mugihe udatewe. Iyo itangiye, isohora voltage imwe n'umurongo w'amashanyarazi wa VCC (ikimenyetso cyo hejuru - urwego).

PNP - NC: Umurongo wo hanze uhujwe n'umurongo w'amashanyarazi wa VCC (usohora ikimenyetso cyo hejuru - urwego) mugihe udatewe. Iyo bikurura, umurongo wo hanze urakinguye (uciwe na VCC).

PNP - NC + OYA: Ifite itumanaho ryinyongera, rishobora gukoreshwa nkuko bikenewe.

Ubwoko bwa NPN: Iyo buteruwe, umurongo wo hanze uhuza umurongo wa 0V, ugasohora ikimenyetso cyo hasi - urwego.

NPN - OYA: Umurongo wo hanze urakinguye (uciwe kuva 0V) mugihe udatewe. Iyo itangiye, isohora voltage imwe n'umurongo wa 0V (ikimenyetso cyo hasi - urwego).

NPN - NC: Umurongo wo hanze uhujwe n'umurongo wa 0V (usohora ikimenyetso cyo hasi - urwego) mugihe udatewe. Iyo bikurura, umurongo wo hanze urakinguye (uciye kuri 0V).

NPN - NC + OYA: Bisa na NPN - NC + OYA, ifite inyongera hanze, ishobora gukoreshwa nkuko bikenewe.

Ibyuma bya NPN bisohora ikimenyetso cyo hasi - urwego (0V), mugihe ibyuma bya PNP bisohora ikimenyetso cyo hejuru (24V).

Kurugero, niba amashanyarazi ya sensor ari 24V, sensor ya NPN izasohoka 0V, mugihe sensor ya PNP izasohoka 24V.

Mugihe uhuza ibyinjira muri PLC, niba ari ibisohoka NPN, itumanaho rya PLC ryinjira rya COM rigomba guhuzwa na 24V. Ibinyuranye, niba ari ibisohoka PNP, itumanaho rya PLC rigomba guhuzwa na 0V.

Icyangombwa ni ukumva icyo PNP na NPN byerekana. P igereranya ibyiza, na N igereranya ibibi. PNP yerekana ikimenyetso cyo hejuru - urwego mubihe bisanzwe, kandi ikimenyetso kiba kibi iyo gitangiye. NPN yerekana ikimenyetso cyo hasi - urwego mubihe bisanzwe, kandi ikimenyetso kiba kinini - urwego iyo rutangiye. Ibisohoka byegeranye byegeranye hamwe na foto ya elegitoronike ni imwe, ariko imiyoboro yabyo iratandukanye. Kubijyanye no gukoresha insinga za PLC, ubwoko bwa NPN bukoreshwa cyane. Benshi mu Buyapani PLCs mubushinwa ni isi - ubwoko cyangwa rusange - ubwoko, bushobora gukoresha ibyuma bya NPN. Itumanaho ryiza rya hafi yegeranye na foto ya elegitoronike itanga amashanyarazi ihujwe no gutanga amashanyarazi meza, itumanaho ribi ryahujwe na terefone isanzwe, naho ibisohoka bihuzwa na PLC yinjira.

Muncamake, kuri switch - ubwinshi bwinjiza bwumuzingi wa PLC, Ubuyapani Mitsubishi PLCs busa nkibikorwa bifatika kandi byizewe kuruta bimwe bizwi - bizwi na PLC nka Siemens. Impamvu nyamukuru nuko abayapani PLCs, harimo na Mitsubishi, bahinduye igishushanyo bize
