MaPLC Anoiswa Sei? Ndeapi Makiyi Ekuita Metrics?

MaPLC Anoiswa Sei? Ndeapi Makiyi Ekuita Metrics?

PLCs inogona kuiswa nenzira dzinotevera:

Nekuumbwa Kwemaitiro:

Integral PLC (kana Unitary PLC): Zvese zvikamu, zvinosanganisira magetsi, CPU, uye I/O interfaces, zvakabatanidzwa mune imwechete imba.

Modular PLC (kana Assembled PLC): Zvikamu zvakaita semagetsi ekupa module, CPU module, uye I/O module yakazvimiririra yakarongeka. Izvi zvinogona kusanganiswa pane yakamisikidzwa rack kana track zvichibva pane chaiyo application zvinodiwa kuti ugadzire yakakwana PLC system.

NeI/O Point Capacity:

Compact PLCs: Kazhinji ine isingasviki 256 I/O mapoinzi, akadai seSiemens S7-200SMART PLC.

Epakati-Size PLCs: Shandisa modular zvimiro uye kazhinji ine maI/O mapoinzi kubva pa256 kusvika 1024, akadai seSiemens S7-300 PLC.

Mahombe PLC: Kazhinji ane anopfuura 1024 I/O mapoinzi, akadai seSiemens S7-400 PLC.

Makiyi Ekuita Metrics ePLCs:

Nepo maPLC kubva kune vakasiyana vagadziri anogona kusiyana mune maficha, ivo vanogovana akati wandei maitiro ekuita metrics:

Input/Output (I/O) Mapoinzi: I/O mapoinzi anomiririra huwandu hwekunze kwekupinza uye kubuda madoko akabatana nePLC pani. Iyo yakawanda I/O mapoinzi aripo, iyo yakawanda yekudzora masimba iyo PLC ine. Ichi ndicho chimwe chezvinhu zvinonyanya kukosha pakusarudza PLC.

Kumhanyisa Kumhanyisa: Iyi metric inoratidza kukurumidza kunoita PLC kuita chirongwa chayo. Iyo inowanzo kuyerwa mumamilliseconds anodiwa kuita 1K mirairo.

Kukwanisa Kuchengetedza: Kuchengetedza kunowanzo kuratidzwa maererano ne kilowords (KW), kilobytes (KB), kana kilobits (Kbit), apo 1K = 1024. Mamwe maPLC anopa kuchengetedza kuwedzerwa.

Mirayiridzo Seti: Iyo seti yekuraira inoratidza simba rinoshanda resoftware yePLC. Iyo yakapfuma yekuraira seti inoreva kwakasimba hurongwa hwekuita.

Internal Registers (Relays): PLCs ine akawanda marejista ekuchengetedza akasiyana, epakati mhedzisiro, uye data. Kugadziriswa kweaya marejista zvakare chiratidzo chePLC mashandiro.

Kuwedzera Kugona: Izvi zvinoratidza kuti PLC inogona sei kubatanidza mamwe mamodule emabasa akasarudzika, akadai seA/D, D/A, kuverenga kwekumhanya-mhanya, kana mamodule ekutaurirana ari kure.

Kuenzanisa Pakati pePLCs uye Relay Control Systems:

Pamberi pekuuya kwePLCs, relay hardwired matunhu aive nzira dzekutanga dzekutonga zvine musoro uye kutevedzana. Dzakanga dzakapfava uye dzisingadhuri asi dzakanga dzisingachinji. Kubva pakaunzwa maPLC, anenge ese maficha ekuita kwavo akadarika ayo erelay control system.

Kuvandudza Maitiro ePLCs:

Kuenda kunoshanda kwepamusoro, kukurumidza kugadzirisa, uye kugona kukuru.

Kuvandudza network uye kugona kutaurirana.

Kuva diki, kudhura zvakanyanya, uye nyore kushandisa.

Kuramba uchivandudza programming software kushanda.

Kugadzira mamodule matsva akagadzirirwa PLC application.

Kusimudzira iyo miniaturization uye software-yakavakirwa shanduko yePLCs.
