Webb demystifies ladder logic by comparing it directly to electrical schematics. You will learn about: the input/output (I/O) modules

The core of Webb’s text lies in its systematic breakdown of PLC architecture and operation. The author moves beyond the "black box" mystique, dissecting the internal components: the central processing unit (CPU), the input/output (I/O) modules, and the power supply. A particularly strong point of the book is its focus on the scan cycle—the continuous process of reading inputs, executing the program, and updating outputs. This concept is vital for timing issues in real-world applications, and Webb treats it with the requisite detail.
