The world your code lives in. TIA Portal is one engineering framework for the whole automation cell — controllers, HMI, drives, safety and networks — with STEP 7 as the PLC editor inside it. One project, shared tags, one download.
TIA = Totally Integrated Automation. Instead of a separate tool per job, one Portal hosts them all, sharing tags and a single project. STEP 7 is the PLC programming part; the rest plug into the same window. Tap each discipline to drop it into one TIA project.

🧠 STEP 7 — the PLC engineering inside TIA Portal: blocks (OB/FB/FC/DB), LAD/FBD/SCL/GRAPH, and the scan model. (Track 01.)
🖥️ WinCC — the HMI/SCADA engineering in the same project, on the same tags as the PLC. (Track 06.)
🌐 PROFINET — the network backbone: the controller is the IO-controller, ET 200 stations are IO-devices. (Track 07.)
🛡️ Safety — a fail-safe program on an F-CPU, engineered right beside the standard program. (Track 08.)
What is TIA Portal, and where does STEP 7 fit?
