Industrial Electrical Schematics Unveiled - Volume 2

Industrial Electrical Schematics Unveiled - Volume 2
Power Circuits, PLCs, Sensors, Industrial Networks, HMIs, and Diagnostics

Can you read an electrical schematic but still struggle to understand how an automated machine actually works?

Volume 2 of Industrial Electrical Schematics Unveiled was written specifically to bridge that gap.

After building a solid foundation in the first volume, you will now move into the core of industrial automation. Using a practical, structured method, you will learn how to interpret power circuits, control circuits, PLCs, sensors, actuators, industrial networks, HMIs, and diagnostic systems.

This is not simply a handbook of electrical symbols.

It is a practical guide that teaches you how to trace a complete machine function-from the field device to the PLC logic, the HMI, and ultimately fault diagnosis.

Inside the book, you will learn how to read and understand:

• Power and control circuits
• PLCs and I/O modules
• Digital and analog sensors
• Electrical and pneumatic actuators
• Variable-frequency drives and servo drives
• Industrial networks, including PROFINET, EtherCAT, EtherNet/IP, Modbus TCP, PROFIBUS, CANopen, IO-Link, and AS-Interface
• HMIs and machine diagnostics
• Troubleshooting techniques
• Technical documentation and machine-function traceability

Each topic is explained through practical examples, annotated schematics, professional infographics, operational checklists, real-world case studies, and knowledge-check quizzes, allowing you to apply what you learn immediately.

By the end of the book, you will be able to:

• Interpret complex industrial electrical schematics correctly
• Trace a signal from the sensor through the PLC and into the HMI
• Understand how power and control circuits operate
• Analyze industrial networks and PLC-based systems
• Identify the causes of faults more quickly
• Improve electrical design, maintenance, commissioning, and testing activities

This book is intended for:

Electrical designers;
EPLAN engineers and designers;
PLC programmers;
Industrial maintenance technicians;
Field service technicians;
Commissioning engineers;
System integrators;
Control-panel builders;
Technical college, vocational school, and university students.

Three digital resource packages are also available for Volume 2: the Starter Digital Resources Pack, the Companion Digital Resources Pack, and the Professional Toolkit. These resources are designed to transform the concepts covered in the book into practical tools for everyday professional use.

Learning how to read an electrical schematic is important. Understanding how the machine operates through that schematic is the skill that separates a technician from a true industrial automation professional.
