They are programmed using ladder logic, a graphical language that resembles electrical relay logic diagrams, making it easier for technicians to understand and implement.
PLCs consist of several key components:
- Central Processing Unit (CPU): The brain of the PLC, responsible for executing the control program.
- Input/Output (I/O) Modules: These modules interface with the external devices, such as sensors and actuators, allowing the PLC to read inputs and control outputs.
- Power Supply: Provides the necessary power to the PLC and its modules.
- Programming Device: A computer or specialized device used to write and upload the control program to the PLC.
