A PLC (Programmable Logic Controller) is a rugged industrial computer that controls processes in real time. It reads data from sensors, decides according to program logic, and drives outputs (motors, valves, relays).
Core components
- CPU
- Program execution + memory
- Input (I)
- Sensor/button signals
- Output (O)
- Driving motors/valves/relays
- Communication
- PROFINET, Modbus, EtherCAT…
Modern PLCs can be compact (integrated I/O) or modular (rack-based); modular designs give flexibility in large plants.
