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 – PROFIBUS

PROFIBUS is an acronym for Process Fieldbus. It is a standard protocol that can be used to connect sensors/transmitters, actuators, controllers, HMIs, VFDs, and more. Two-core twisted, shielded cables called PROFIBUS cables (Figure 13.8) are used for communication. A PROFIBUS connector (Figure 13.12) is used to connect to each device in the network. The PROFIBUS protocol comes in two forms, as follows:

  • PROFIBUS DP (Decentralized Peripherals): PROFIBUS DP is among the most commonly used network protocols in the industry. It is an industrial network protocol that reduces the number of wires required to connect sensors and actuators by decentralizing the input and output (I/O) modules.

Before PROFIBUS DP, I/Os were centralized in the control room, as shown in the following diagram, leading to lots of cables being used to wire sensors and actuators (which could be far away from the control room) to the input and output...
