Industrial IoT and Control Systems in Manufacturing
Course Description
Modern manufacturing is undergoing a revolution. Sensors, controllers, and networks are turning factories into intelligent, data-driven environments. This course from Cisco Networking Academy introduces you to the world of Industrial IoT (IIoT) and control systems that power Industry 4.0.
You'll learn the fundamentals of industrial automation: how programmable logic controllers (PLCs) work, what SCADA systems do, and how sensors and actuators connect to networks. The course covers industrial networking protocols (Ethernet/IP, Modbus, PROFINET), the Purdue model for industrial network architecture, and the unique cybersecurity challenges of operational technology (OT). You'll explore real-world manufacturing scenarios—from assembly lines to process control—and understand how IIoT enables predictive maintenance, quality control, and efficiency gains.
This free, self-paced course takes about 15 hours to complete. It's ideal for industrial engineers, manufacturing technicians, IT professionals moving into OT, and anyone interested in the future of smart manufacturing. Basic networking knowledge is recommended. Upon completion, you'll earn an official Cisco digital badge.

User Reviews
"I've worked in manufacturing for 15 years, but I never really understood the network side of things. This course connected the dots for me. The explanation of PLCs and SCADA was clear, and the Purdue model finally makes sense. The cybersecurity module is especially valuable now that our plant is connecting more systems to the internet. Highly recommended for anyone in industrial operations."
"An excellent introduction to IIoT. I'm an IT professional moving into OT security, and this course gave me the foundational knowledge I needed. The section on industrial protocols (Modbus, PROFINET) was particularly helpful. The Cisco badge is a nice credential. My only critique: more hands-on lab exercises would be welcome, but for a free course, it's very good."
"This course opened my eyes to a whole new field. I'm a recent mechanical engineering graduate, and I had no idea how much networking and IT are involved in modern manufacturing. The real-world case studies (especially predictive maintenance) showed me where the industry is heading. I've already applied for jobs in industrial automation. Thank you Cisco!"
