TIA Portal is an engineering framework for the automation cell. It brings controller programming, HMI engineering, drives, safety and network configuration into a shared project, with STEP 7 providing the PLC programming tools. The disciplines can share tag information, while each device still needs the configuration and program intended for that target.
TIA = Totally Integrated Automation. The Portal brings the engineering tools into a shared environment so that controller, screen and network work can use the same project information. STEP 7 provides the PLC programming part. The other engineering tools work alongside it. Select a discipline in the example to see where it belongs in the project and how its work relates to the controller.

🧠 STEP 7 provides the PLC engineering tools inside TIA Portal. You use it to work with blocks (OB/FB/FC/DB), program in LAD/FBD/SCL/GRAPH where supported, and examine how the CPU runs that program through its scan model. (Track 01.)
🖥️ WinCC provides HMI/SCADA engineering. A screen can use tags from the controller project to display process values and send operator requests. Sharing those tag definitions connects the screen engineering with the PLC program that uses them. (Track 06.)
🌐 PROFINET connects the controller to distributed I/O. The controller acts as the IO-controller, while ET 200 stations act as IO-devices exchanging the input and output data configured for the machine. (Track 07.)
🛡️ Safety provides engineering for a fail-safe program on an F-CPU alongside its standard program. The F-program performs the configured safety functions; ordinary PLC logic and HMI controls do not replace that safety layer. (Track 08.)
What is TIA Portal, and where does STEP 7 fit?
