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.

Getting started with languages

PLCs can be programmed in a variety of different languages and different PLCs from different manufacturers may implement slightly different variations of those languages.

Not all PLCs support multiple languages, and the ones that do support more than one language do not necessarily allow for that language to be fully implemented. The general correlation between PLCs and language support comes down to cost – the more expensive a PLC is, the more likely it is to support more than one language type.

Note

Siemens PLCs, when programmed with TIA Portal, support multiple languages, even at the lower ranges.

Available languages

Before you select a language for the task at hand, it's important to know what is available and what that may mean for the project that's being developed.

LAD – ladder logic

Ladder logic is a graphical language based on contacts, coils, and instruction blocks.
