—a gray, unassuming box that promised to replace miles of copper wiring with a few lines of code. Before the advent of the PLC

Programmable Logic Controllers (PLCs) are the bedrock of modern industrial automation. Before the advent of the PLC, manufacturing processes were controlled by relay logic—physically wired panels that were difficult to modify and troubleshoot. John W. Webb’s text addresses the technology that replaced these rigid systems.
