Learn OT networking basics through practical labs covering IP setup, switches, MAC addresses, and OSI layers.

What you'll learn:
  • Understand how routers, switches, and devices communicate to form reliable industrial and home networks.
  • Learn the key differences between IT and OT networks used in manufacturing environments.
  • Configure and troubleshoot basic OT networks, including IP setup, MAC identification, and connectivity tests.
  • Grasp how data flows through OSI layers and supports control, safety, and SCADA systems on the plant floor.

Understanding how industrial networks work is one of the most valuable skills for engineers and technicians in today’s manufacturing environment. This course introduces you to the foundations of Operational Technology (OT) networking and gives you the practical knowledge to build, connect, and troubleshoot real systems on the plant floor.

You will start from the very beginning, learning what makes a network function, how industrial devices exchange information, and how plant-floor systems differ from traditional IT networks. Each lesson builds on the last, combining clear explanations, whiteboard visuals, and guided hands-on labs that bring every concept to life.

By the end of this course, you will understand how to connect your laptop to an industrial device, interpret IP and MAC addresses, and diagnose the most common communication problems found in OT environments.

What You Will Learn

  • The fundamentals of how routers, switches, and devices communicate in a network

  • The key differences between IT and OT networking in manufacturing systems

  • The structure and purpose of the OSI model with a focus on Layers 1 to 3

  • How to identify devices using MAC addresses and configure IP addresses for industrial equipment

  • The importance of network reliability, data flow, and safety signals in control systems

  • How to connect to PLCs, HMIs, and other OT devices using your laptop

  • Practical troubleshooting methods for resolving basic network and communication issues

Why This Course Matters

  • Learn from real industrial experience, not theory

  • Follow along with labs and demonstrations that mirror real factory systems

  • Build confidence to design and maintain small OT networks

  • Prepare yourself for more advanced topics such as VLANs, NAT, and managed switch configuration

This course is perfect for technicians, engineers, and students who want to understand the communication backbone of modern industrial automation. No previous networking experience is required — only curiosity and a desire to learn how real plants connect and operate.
