Industrial Automation from Scratch

By: Olushola Akande

Overview of this book

Industrial automation has become a popular solution for various industries looking to reduce manual labor inputs and costs by automating processes. This book helps you discover the abilities necessary for excelling in this field. The book starts with the basics of industrial automation before progressing to the application of switches, sensors, actuators, and motors, and a direct on-line (DOL) starter and its components, such as circuit breakers, contactors, and overload relay. Next, you'll explore VFDs, their parameter settings, and how they can be wired and programmed for induction motor control. As you advance, you'll learn the wiring and programming of major industrial automation tools – PLCs, HMIs, and SCADA. You’ll also get to grips with process control and measurements (temperature, pressure, level, and flow), along with analog signal processing with hands-on experience in connecting a 4–20 mA transmitter to a PLC. The concluding chapters will help you grasp various industrial network protocols such as FOUNDATION Fieldbus, Modbus, PROFIBUS, PROFINET, and HART, as well as emerging trends in manufacturing (Industry 4.0) and its empowering technologies (such as IoT, AI, and robotics). By the end of this book, you’ll have gained a practical understanding of industrial automation concepts for machine automation and control.

Common industrial network protocol – Modbus

Modbus is an open protocol that can be used by any manufacturer or vendor without restriction. It was originally designed in the mid-1970s by Modicon as a way to connect intelligent devices with PLCs using a simple master/slave concept. It was initially designed for Modicon PLCs only (that is, a proprietary protocol) but it was later made available for use by any manufacturer without any restriction (that is, an open protocol).

Various vendors now manufacture their PLCs and other industrial devices to support the Modbus protocol. Hence, you will find the Modbus protocol available for use in industrial equipment from various manufacturers, such as Siemens, Allen Bradly, Mitsubishi, and Omron. The Modbus protocol solves the problem of communication between industrial equipment from different manufacturers. With the Modbus protocol, a Siemens PLC can communicate with an Omron PLC, Allen Bradley PLC, Omron VFD, or any other industrial...
