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.

PLC-driven alarming

When a PLC and an HMI exist in the same project, common alarm classes can be configured for use in both devices.

Using supervisions and the ProDiag function block, the PLC can drive alarms to the HMI without having to configure HMI alarms in the HMI itself. One of the biggest benefits of using PLC-driven alarming is that the alarm resides in the function block associated with a supervision. This means that if the function block is standardized in a library, every project that uses the function block will be able to generate the same alarm automatically.

Supervisions can easily be created for any variable that is stored in a data block or as a PLC tag:

In the Supervision column, right-click and choose Add new supervision. The properties window at the bottom of the screen opens on the Supervisions tab.
