Overview of this book

When it comes to using the core and managed services available on AWS for making decisions about architectural environments for an enterprise, there are as many challenges as there are advantages. This Industrial IoT book follows the journey of data from the shop floor to the boardroom, identifying goals and aiding in strong architectural decision-making. You’ll begin from the ground up, analyzing environment needs and understanding what is required from the captured data, applying industry standards and conventions throughout the process. This will help you realize why digital integration is crucial and how to approach an Industrial IoT project from a holistic perspective. As you advance, you’ll delve into the operational technology realm and consider integration patterns with common industrial protocols for data gathering and analysis with direct connectivity to data through sensors or systems. The book will equip you with the essentials for designing industrial IoT architectures while also covering intelligence at the edge and creating a greater awareness of the role of machine learning and artificial intelligence in overcoming architectural challenges. By the end of this book, you’ll be ready to apply IoT directly to the industry while adapting the concepts covered to implement AWS IoT technologies.

PLC hardware and architecture

PLCs mainly are built around the central processing unit, a real-time and deterministic processor. It is interfaced with memory units that store programs and data. Most PLCs run on 24 or 48 V DC supply. PLCs are also built modularly by having pluggable cards that can be expanded and customized based on the application scenario. The Input/Output (I/O) cards or modules are usually expandable and can be configured. These cards typically deal with analog and digital signals.

High-speed Pulse-Width Modulation (PWM) sampling circuits are also built in, making the PLCs capable of processing fast signals in real time. The communication modules are, last but not least, key here too. There are communication ports for programming the PLC, obtaining diagnostic information, and interfacing with peer PLCs, networks, and sensors. They help transmit the information upon which the external data logic can be built. Figure 7.1 shows the hardware architecture of a generic...
