Programmable Logic Controllers - Principles and Applications
Example: Conveyor Motor Control
- Inputs: Start (NO), Stop (NC), Prox sensor (part present).
- Outputs: Motor contactor.
- Ladder: Seal-in circuit + part counting (counter) → stop after N parts.
9. Practical Applications (Chapter 21+)
Core Components of a PLC
- Processor (CPU): Executes control instructions, performs arithmetic and logic operations, and manages memory.
- Memory: Stores the operating system, user program, and data tables (input/output images).
- Input/Output (I/O) Modules: Interface between the PLC and field devices. Discrete I/O handles on/off signals; analog I/O processes continuous values like temperature or pressure.
- Power Supply: Converts line voltage to the low DC levels required by the PLC’s internal circuits.
- Programming Device: Typically a personal computer running ladder logic software (e.g., RSLogix, TIA Portal).
