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.

Understanding the functions of SCADA

The meaning of SCADA already implies its major functions. The following goes into detail about what a SCADA system does:

  • It controls industrial processes either locally or remotely. Switching on or off a machine, increasing or decreasing setpoints, and so on are control functions that a SCADA system can be programmed to perform.
  • It collects data (acquires real-time data) from a field or machine, which provides a status indicator to the operator or process engineer for monitoring.
  • It enables a process engineer to have a bird’s-eye view of an entire plant, which can consist of various machines/devices at different geographical locations.
  • It generates alarms when abnormal conditions occur within a process. It can trigger alarms that can be in the form of audible sounds, lights, emails, SMS, or other forms when something is wrong in a process.
  • It records events (data logging).
