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.

Chapter 13: Downloading to the PLC

Downloading to a Programmable Logic Controller (PLC) is an important and necessary part of any project. It is the point at which an offline project or modification is actually sent to the CPU. A download might consist of just software changes or also hardware changes. TIA Portal does a great job at managing this download process to ensure it occurs fault free. This chapter explores, in detail, how the download process works in TIA Portal and what is new in TIA Portal 17. Before making downloads to a PLC, it's important to understand the actions that TIA Portal needs to take and what this could mean for data in the PLC.

In this chapter, we will cover the following topics:

  • Downloading to a PLC
  • Retaining data in optimized and non-optimized blocks
  • Uploading from a PLC
  • Considerations
