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 – HART

The Highway Addressable Remote Transducer (HART) protocol is the world standard protocol and provides data exchange between smart/intelligent field devices and a controller (PLC, DCS, and so on) or handheld communicator. You can control and monitor HART-enabled field devices (sensors, transmitters, and actuators) with the HART protocol. In HART communication, a digital signal is superimposed on the traditional 4-20mA analog signal, allowing the 4-20mA analog signal to co-exist with the digital signal on the same two-wire loop without distortion. Hence, two signals are transmitted simultaneously – that is, the 4-20mA signal and the digital signal. The 4-20mA analog signal represents the measured variable regarding the temperature, pressure, level, or flow while the digital signals carry other device details, such as the device’s health, status, diagnostics alerts, and more.

Each sensor/transmitter and actuator (transducer...
