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.

Overviewing the SCADA hardware

The hardware components of a SCADA system include the following:

  • Field devices: These are sensors, transmitters, and actuators that are directly connected to the machine or plant and generate a digital or analog signal for monitoring. Sensors or transmitters are for monitoring machine status or parameters, while actuators are for carrying out control action on equipment or a machine.
  • Remote station: This can be a PLC or a Remote Terminal Unit (RTU). It is installed at a remote site where the machine or equipment to be monitored or controlled is located. Field devices (sensors, transmitters, and actuators) are connected to remote stations (a PLC or an RTU) to allow monitoring and control from the host computer at a remote site via a network. It gathers data through the sensors connected to it and transfers them to the host computer via a network. It also transfers an electrical control signal from the host computer to the actuators connected...
