Coare Plc vaega & Infaces

I tala atu o CPU, manatua, ma Fesootaiga Ports, PLCS foliga taua pisinisi sailiili:

1. Input interfaces

• Maua faʻailoga mai le fanua o fanua e ala i OPto-ulugalii ma faʻamatalaga o loʻo i ai.

• Eletise eletise ma tuʻutuʻuga faʻailoga / logic faʻailoga (e.g., switches, atigivae).

1. Oloa i fafo

• Faʻatinoina o le Pusa Faʻatonutonu e ala i OPto-ulugalii ma oloa i fafo:

• Fesootai: taulimaina AC / DC utaina (≤2a), lemu tali (10ms)

• Transsors: DC uta naʻo, maualuga-saoasaoa fesuiaʻiga (0.2MS)

• Thyristors: AC uta na o le, auala saoasaoa (1ms)

Fausaga plc Vasega

Plc faagaoioia mataupu faavae

Scan Rycle Workflow

1. Nofoaga i totonu (diagnostics)

2. Auaunaga Fesootaiga (faamatalaga fesuiaiga)

3. Input sampling (Faitau uma Inputs)

4. Polokalame Polokalama (Tamoe Logtic)

5. Oloa o loʻo faʻafouina (lata mai o le 'au)

O le vave faitau le umi e faalagolago ile:

• CPU saoasaoa (μs / faatonuga)

• Polokalame faigata

• I / o module faitau

Ou / O tali laga

• Faʻasino i aʻu / o le avanoa modules

• Faalavelaveina-aveina gaosi

• Maualuga-saoasaoa claters (> 100khz)

100khz)

Tulaga filifilia filifilia

• Sorware Connecigation

• Fausaga: iunite mo le faigofie vs modular mo le tele

I / o modules: ≥20% o le mafai ona maua mo le lumanaʻi

• Manatu Manatu

Faatatau: (i / o manatu × 10) + (timmer × 5) = Laititi polokalame

• Faapitoa modules

• Analog I / O (4-20s, ± 10v)

• Auina mai le taofiofia (Stepper / Servo)
