Description
Industrial Internet of Things (IIoT) gateways play a critical role in modern Industry 4.0 systems by bridging the gap between operational technology (OT) and information technology (IT). This course provides a clear, structured, and practical introduction to IIoT gateways, focusing on how data flows from industrial field devices to edge systems and cloud platforms.
You will start by understanding what IIoT gateways are and why they are essential in smart manufacturing, energy systems, and industrial automation. The course explains gateway architecture layer by layer, including field devices, protocol adapters, edge processing, security components, and cloud connectivity.
Rather than staying theoretical, the course uses realistic examples and simulations to demonstrate how gateways work in practice. You will explore common industrial protocols such as Modbus, OPC UA, MQTT, and Ethernet-based communication, and learn how gateways normalize and process data coming from PLCs, sensors, drives, and other industrial equipment.
The course also introduces edge computing concepts, showing how data can be filtered, aggregated, and analyzed locally before being sent to the cloud. Through simple but meaningful Python and JavaScript gateway simulations, you will see how telemetry data is collected, processed, and prepared for cloud platforms.
This course is vendor-neutral and focuses on core concepts that apply across different hardware platforms and software stacks. It is designed to build a strong conceptual foundation for anyone who wants to work with IIoT systems, edge architectures, or industrial data pipelines.
By the end of the course, you will clearly understand how IIoT gateways fit into modern industrial systems and how they enable reliable, scalable, and secure industrial connectivity.
Who this course is for:
- Engineers and technicians who want to understand Industrial IoT and IIoT gateway concepts
- Software developers interested in industrial systems, edge computing, or IoT architectures
- Automation, manufacturing, and energy professionals transitioning into Industry 4.0 projects
- Students and graduates seeking a solid conceptual foundation in IIoT systems
- Technical managers or architects who need a clear overview of IIoT gateway architectures
