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.

Automated filling, capping, and wrapping system using PLC

The following diagram shows another industrial application of PLC:

Figure 9.51 – Filling, capping, and wrapping

Figure 9.51 – Filling, capping, and wrapping

The start push button (normally open) is connected to I0.0, while the stop push button (normally closed) is connected to I0.1. A conveyor motor is connected to Q0.0, a fill valve is connected to Q0.1, a capping machine is connected to Q0.2, and a wrapping machine is connected to Q0.3. A fill position sensor is connected to I0.2 and a cap position sensor is connected to I0.3, while a job out sensor is connected to I0.4, as indicated in the preceding diagram.

When the start push button is pressed and released, the conveyor motor should start running until the bottle gets to the fill position sensor; in other words, the fill position sensor detects the bottle and the conveyor motor stops.

The fill valve should open as soon as the conveyor motor stops at the fill sensor for 10...
