PLC Engineering Series

The PLC Engineering Series explains programmable logic controllers from the practical perspective of real industrial machines. It covers PLC architecture, inputs and outputs, programming methods, sequence control, diagnostics, industrial communication and the interaction between software logic and physical equipment.

The emphasis is on understanding how a PLC-controlled machine actually behaves. The books show how to trace signals, interpret logic, diagnose missing conditions, identify communication and I/O problems, and connect the program with sensors, actuators and the process itself. The series is written for maintenance technicians, electricians, automation engineers and readers who want a structured path from PLC fundamentals to practical troubleshooting and industrial applications.
