Programmable Logic Controller (PLC):

PLC is an industrial computer that consists of

1. Power supplies
2. Central Processing Unit board (CPU)
3. Input module which consists of switches or terminals
4. Output module which consists of lights or terminals

The program to be used for PLC is called Ladder program.

In this book, Allen-Bradley SLC 500 series PLC will be explored.
