Nduzi PLC: Ihe owuwu, oru & nhọrọ

Isi plc mejupụtara & oghere

Afe na CPU, ebe nchekwa, na ọdụ ụgbọ mmiri, PLCS njirimara dị oke egwu na:

1. Ntinye ntinye

• Anata akara site na ngwaọrụ ubi site na opko-coundles na sekiit na-abanye.

• Electricals e nwere oghere na ọnọdụ ihe nnọkọ ihe nkiri (E.G., ntụgharị, ihe mmetụta).

1. Mmepụta mmepụta

• Igbu iwu na-egbochi iwu site na ndị na-enweghị ike na mpaghara mmepụta:

• Relays: Jiri Ibu Ac / DC (≤2a), nzaghachi nwayọ (10ms)

• Ndị na-ebugharị: DC ibu naanị, ịgbanwee ịgbanwee (0.2ms)

• Ndị isi: AC ibu naanị, na-agba ọsọ (1ms)

PLC na-arụ ọrụ

Nyochaa usoro njem

1. Nhazi nke ime (nyocha)

2. Ọrụ Nkwukọrịta (Mgbanwe data)

3. Ntinye nlele (Gụọ ntinye niile)

4. Ememme Mmemme (Gburugburu)

5. Mmepụta ume ọhụrụ (melite ndị na-eme ihe)

Oge nyocha na-adabere na:

• CPU ọsọ (μs / nkuzi)

• Mmebi mgbagwoju anya

• M / O modulu agụ

• Direct i / O Nweta modulu

• Nkwụsị mkpado

• Nhazi ngwaike

• Ihe owuwu: Arụmọghị maka ịdị mfe vs modular maka slubility

M / O modulu: ≥20% ikike maka mgbasawanye ọdịnihu

• Ihe Nchọta

Atụmatụ: (I / O Nzipụta × 10) + (Times × 5) = Nzọụkwụ kacha nta

• Modulu pụrụ iche
