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.

Summary

This chapter has covered the setting of properties and the dynamization of properties, as well as scripting and raising events. All of these are required in order to successfully interact with the HMI and any associated PLCs connected to the HMI.

Understanding when to use scripts over the built-in configuration menus is something unique to each programmer and application developed. It is important to remember that scripting should be used only when needed and not for the sake of it. Large scripts can cause issues if there are too many running at once.

The next chapter explores connecting structured data from a PLC to predefined faceplates in an HMI, allowing large datasets to be retrieved and utilized easily while maintaining a standardized and structured approach.
