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.

Interfacing PLCs and HMIs

In Chapter 9, Deep Dive into PLC Programming with TIA Portal, we learned how to use pushbuttons to start and stop and also how to use a lamp as an indicator that shows when a load is on or off.

As we discussed earlier, HMIs allows human operators to interact with machines via a PLC. This means that a PLC is required to communicate with the machine.

Here, in this section, we will learn how to interface a Siemens HMI (KTP 400) and a Siemens PLC using Profinet as a communication protocol. We will use TIA Portal to program the PLC and develop the HMI application using WinCC, which was installed when we installed TIA Portal in Chapter 8, Understanding PLC Software and Programming with TIA Portal.

By the end of this section, you should be able to interface PLCs and HMIs such that the HMI can be used to start and stop and get feedback on the status of a machine (for example, a motor).

We are already familiar with the Siemens S7 1200 PLC (CPU 1211C). The...
