Logic Fundamentals:
Before touching code, Webb emphasizes the transition from hard-wired relay logic to digital logic. This includes understanding AND, OR, and NOT gates and how they translate to industrial workflows. executes the program

- Scanning: The PLC continuously scans the input devices, executes the program, and updates the output devices.
- Input/Output (I/O) Operations: The PLC reads inputs from sensors and devices and sends outputs to actuators and devices.
- Logic Operations: The PLC performs logical operations, such as AND, OR, and NOT, to control the system.
- Timing and Counting: The PLC can perform timing and counting operations to control and monitor processes.
