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.

Downloading to an HMI

The principles behind downloading to an HMI are very similar to that of a PLC. Starting a download is performed in the same manner – by selecting the HMI in the project tree and then clicking on the Download button. Additionally, the right-click menu can be used to initiate a download.

When the Load preview window is displayed, the options differ from an HMI to a PLC:

Figure 14.6 – Load preview

The HMI Load preview window has more actions available than the PLC Load preview window, and these actions directly affect how the download is completed:

  • Load Runtime: Under certain conditions, a Delta download option is available rather than a Full download option. Delta download allows the HMI to continue running during the download process, and only changes are downloaded as opposed to the entire download. When a Full download occurs, the HMI must be stopped temporarily, and this happens automatically.
  • Runtime start...
