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.

Data ingestion and data analysis

An interesting use case in the production facilities is to interface energy meters to the central PLC. Traditionally, energy meters are part of utility management and are isolated from the production facility. They are present at an aggregated level and are usually used for metering purposes, but interfacing energy meters to production-line PLCs opens up a plethora of opportunities: line-wise energy and cost comparison, shift-wise energy utilization (used for time-based tiered energy costs), demand planning, and so on. We will focus our efforts on the process of integration, namely using the Modbus protocol.

Modbus is one of the oldest yet simplest field bus protocols based on master-slave topology over a serial line, RS232/RS485. The protocol was introduced for communication between PLCs and other systems. Figure 7.14 shows the interface of the energy meter to the PLC using the Modbus protocol.
