Yakatemerwa Nhungamiro yePlc Zvivakwa: Architecture, Operation & Sarudzo Crosseria

Core PLC zvikamu & Interfaces

Beyond CPU, Memory, uye Zviteshi zvekutaurirana, PLCS inoratidza koshiririka maindasitiri:

1. Input intersfaces

• Gamuchira masaini kubva pamidziyo yemunda kuburikidza neishto-clomputers uye yekuisa matunhu.

• Electrically isolates uye mamiriro ezvinhu sensor / logic masaini (i.e., switch, sensors).

1. Inobuda

• Kubata kutonga kunoraira kuburikidza neOPTO-Colums uye zvinoburitsa zvikamu:

• Kudzokorora: Bata AC / DC mitemero (≤2A), Inononoka Mhinduro (10ms)

• Transistors: DC mitare chete, yakakwira-kumhanya switching (0.2ms)

• Varidzi veKanante: AC Mitoro chete, yepakati kumhanya (1ms)

Scan Cycle Workflow

1. Kugadziriswa kwemukati (diagnostics)

2. Kukurukurirana Services (data rekuchinjana)

3. Input Sampling (Verenga zvese zviputi)

4. Kuuraya chirongwa (mhanya pfungwa)

5. Kuburitsa Refresh (gadziridza maatta)

Scan Nguva dzinoenderana ne:

• CPU Speed (μs / kuraira)

• Chirongwa kuoma

• I / o module kuverenga

I / o kupindura lag mhinduro

• Direct i / o kuwana module

• Kupindira-kutungamirwa kugadzirwa

• Yakakwira-Speed Colowers (> 100khz)

Key Select Sticlea

• Hardware inogadziriswa

• Chimiro: Yunivhesiti yekunyatsemesa vs modular ye scalability

I / o modules: ≥20% spare kugona kwekuwedzera mune ramangwana

• Memory zvinodiwa

Fungidzira: (i / o mapoinzi × 10) + (nguva × 5) = Minimum chirongwa matanho

• Inyanzvi Module

• Analog I / O (4-20ma, ± 10V)

• Motion Kudzora (STPPER / SERPO)

Kukurukurirana (profinet, ethercat)

Technical faq

Q: Chii chinotsanangura plc?

* A: Industrial Dhijitari komputa ine yakarongedzwa ndangariro dze:

Logic / kutevedzana kutonga

Chaiyo-nguva i / o manejimendi

Kuenderera mberi process auto *

Q: Zvinetso zvemukati zvekudzokorora?

Input / Output Relay (X / Y)

Auxilia Ready (m)

Nguva (t), kuverenga (c)

Data Regeraista (d)

Q: Contacor kushanda?

Electromagnetic coil inosimbisa → inoshamisa contacts padyo

Arc chutes inodzivirira spark panguva yekubvisa
