Industrial Automation & OT Domains: From PLCs to Cybersecurity

 Industrial Automation & OT Domains: From PLCs to Cybersecurity


Most people think industrial automation = PLC programming.
But that’s just one piece of a much bigger system.

Modern OT (Operational Technology) brings together multiple domains - all working as one to run, monitor, and secure industrial processes.

I created this roadmap to make that big picture easier to understand 👇
It covers the full lifecycle:

Design → Build → Operate → Secure

And highlights the key domains every engineer should know:

• PLC & HMI Programming
• SCADA & High-Level Monitoring
• Industrial Communication Protocols
• Distributed Control Systems (DCS)
• Motion Control & Robotics
• Industry 4.0 & IIoT
• Smart Factory & Edge Computing
• Functional Safety
• OT Cybersecurity (IEC 62443)
• Digital Twin & Virtual Commissioning

The reality:

The best engineers don’t just know one tool they understand how systems connect end-to-end.
That’s what makes operations reliable, efficient, and secure.

Which part of this roadmap are you focusing on right now?

Personal views only; not representative of My current and past employment experiences.

Cathodic Corrosion Protection Systems: A Guide for Oil and Gas Industries

Gul Bahar Shah
Cathodic Corrosion Protection Systems Cathodic Corrosion Protection Systems: A Guide for Oil and Gas Industries Preface Contents Preface The oil and gas industry depends on steel and other metals for pipelines, storage tanks, and infrastructure. However, these metals can corrode when exposed to water or soil, which is detrimental to the integrity of pipelines and storage tanks. This engineering book outlines the minimum requirements for anodes (high-silicon iron, graphite, magnetite) used in impressed current CP systems. It details the composition, materials, manufacturing, properties, inspection, and testing of these anodes. Additionally, it provides revised survey requirements to ensure corrosion control systems on buried or submerged structures are well-designed, operated, and maintained. The book also covers techniques, equipment, ...
