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.

Uploading from a PLC

PLC programs can also be uploaded out of the PLC and back into the TIA Portal project, which is useful if the version of the offline project does not match the project in the PLC:

Figure 13.19 – An example of an unmatching online project

The project tree will identify any objects that are not consistent with the online project. By right-clicking on an object and selecting the Upload from device (software) option, the Upload preview dialog box will open:

Figure 13.20 – Upload preview

The Upload preview window displays information about the upload that is about to take place and also asks the programmer for a decision regarding conflicting objects. A conflict is detected when a block that is different in the offline project has the same name as an object in the online project.

The programmer can choose the Action option, deciding to either Overwrite or Insert with different name.
