PLC and HMI Development with Siemens TIA Portal

By: Liam Bee

Overview of this book

With automation requirements on the rise, Siemens’ TIA Portal development environment is almost a necessity for any automation engineer. The Totally Integrated Automation (TIA) environment helps seamlessly integrate all things automation, from PLC hardware and software design to HMI development. This book helps you understand the tools available in the TIA toolbox and shows you how to write code effectively. The book begins by introducing you to the TIA environment, covering the layout and tools available. Once you’ve got to grips with the environment, you’ll find out how to create hardware to write programs against, including adding IO modules and assigning memory for input and output. Next, you'll develop logic in all of the languages that TIA Portal offers, such as Ladder, Function Block Diagram, and Structured Text (SCL) (note that Statement List is not covered as a deprecated language), as well as the newest language, Cause and Effect (CEM). You’ll also discover how to store standard code in libraries, creating a version control system that is easy to manage and aids standard design. Finally, following the PLC design chapters, you’ll learn how to develop HMI applications in TIA Portal’s latest unified hardware. By the end of the book, you'll be well equipped to use all of the features that TIA Portal V17 offers.

The control scenario

This chapter focuses on a control scenario for a basic sand filter. The scenario is simplified enough that the control aspects are simple but enough of the languages is explored to understand how to use them and demonstrate strengths and weaknesses.

The languages explored in this chapter will be used for the following control scenario:

Figure 5.1 – Chapter control scenario

The flow control diagram in Figure 5.1 demonstrates a simple method to relay how the controls are expected to operate for each of the languages used in this chapter.

A graphical representation of the process is available via a Comfort Panel Human Machine Interface (HMI).
