1. PLC

Programmable Logic Controller. It is an industrial digital computer designed for controlling manufacturing processes, machinery, or robotic devices. PLCs are widely used in automation systems because they are rugged, reliable, and capable of real-time control.

Key Features of a PLC:

1. Programmability – Can be programmed using ladder logic, structured text, or function block diagrams.


2. Real-time Operation – Executes control logic in real-time for precise automation.

3. I/O Modules – Interfaces with sensors (inputs) and actuators (outputs) to control a process.

4. Rugged Design – Built to withstand harsh industrial environments with dust, moisture, and vibrations

5. Communication – Can integrate with other automation systems using protocols like Modbus, Ethernet/IP, or Profibus.
