The Anatomy of a PLC A typical PLC consists of several key components:

1. CPU (Central Processing Unit): Acts as the brain of the PLC, executing the programmed logic.
2. Memory: Stores the program instructions and data.
3. Input Modules: Interface with sensors and other input devices to receive signals from the equipment being controlled.
4. Output Modules: Interface with actuators and other output devices to send control signals to the equipment.
5. Communication Ports: Facilitate communication between the PLC and other devices or systems, allowing for real-time monitoring and control.
