PLC Engineering Advanced

Modern PLC engineering extends far beyond basic logic and ordinary I/O control. Advanced systems must coordinate functional safety, servo motion, redundant controllers, industrial networks, HMI and SCADA platforms, historical data, cybersecurity, and production requirements as one reliable and diagnosable architecture.

PLC Engineering Advanced is a practical, vendor-neutral guide to designing, integrating, commissioning, and maintaining complex industrial automation systems. It explains how the different layers of a modern control system interact—and how weaknesses at the boundaries between software, wiring, networks, drives, sensors, safety devices, and mechanics become real production failures.

WHO THIS BOOK IS FOR

This book is written for:

• Automation and control engineers
• Experienced PLC programmers

• Machine builders and control-system designers
• Technical professionals moving beyond basic PLC applications

WHAT YOU WILL LEARN

Inside this book, you will learn how to:

• Design functional-safety architectures with safety PLCs
• Understand safety inputs, outputs, reset logic, and restart prevention
• Apply diagnostic coverage, proof testing, and validation principles
• Integrate servo drives, encoders, and coordinated motion
• Configure homing, positioning, electronic gearing, and axis synchronization
• Diagnose following error, tuning problems, and mechanical limitations
• Design redundant controllers, networks, power supplies, and recovery paths
• Understand failover, state synchronization, output ownership, and common-cause failure
• Integrate HMI, SCADA, historian, and reporting systems
• Design alarms, trends, commands, permissions, and data-quality handling
• Use OPC UA, time synchronization, and secure remote access
• Plan FAT, SAT, I/O checkout, loop testing, and cause-and-effect verification
• Perform fault injection, endurance testing, and performance validation
• Manage backups, restoration, modifications, and system lifecycle
• Investigate intermittent faults and complete root-cause analysis

TECHNICAL AREAS COVERED

The book examines the main technologies, architectures, and engineering methods used in advanced PLC systems, including:

• Safety PLCs and functional-safety architecture
• IEC 61508 and ISO 13849 concepts
• Servo positioning and coordinated motion
• Homing, gearing, synchronization, tuning, and following error
• SCADA, HMI, historians, alarms, trends, and reporting
• OPC UA communication and time synchronization
• Industrial cybersecurity, permissions, and remote access
• FAT, SAT, commissioning, and operational handover
• Cause-and-effect testing and sequence validation
• Performance, capacity, endurance, and recovery testing
• Backup, restoration, change control, and lifecycle management
• Intermittent-fault capture and corrective action

WHY THIS BOOK MATTERS

Complex automation systems rarely fail in only one layer. A servo problem may begin in mechanics, a safety trip may come from reset logic, a redundant controller may still share one vulnerable power path, and a SCADA alarm may reflect stale or low-quality data.

This book treats advanced automation as one connected system. Realistic industrial cases show how failures develop across technical boundaries and how structured design, testing, diagnostics, and documentation reduce risk.

PLC Engineering Advanced is intended for professionals who already understand basic PLC principles and want to design safer systems, coordinate motion accurately, improve availability, diagnose complex failures, and commission industrial automation with confidence.
