Ten tracks of theory, one real machine. We'll build a bottle-capping cell the way a Siemens engineer actually does — define the data, write the reusable logic, give it a face, wire it to the field, and guard it with safety. Each step pulls a concept from the course and snaps it into place. Build it, then run it.
Click the steps in order (or any order — it's a sandbox). Each one adds a piece to the cell above and explains which track it comes from, with a link back. When all six are in, the cell is complete: press ▶ Run cell to cap bottles, and hit the E-stop to prove the safety layer overrides everything.
That's a real project skeleton: data → logic → I/O → HMI → safety → diagnostics. Every machine you'll ever build in TIA follows this same spine. The tracks taught the pieces; the order is the craft.
🧠 How it thinks — the scan cycle & OBs (T01), the process image & tags (T02), the four languages (T03). The foundation under every line above.
🧩 How it's built — blocks & reuse (T04), UDTs (T05), libraries & versioning (D5). Why FB_Capper is one block you'd deploy to every cell.
🔌 How it connects — WinCC HMI (T06), PROFINET & the field (T07), the internals (D3). The cell talking to operators and I/O.
🛡️ How it stays safe & alive — fail-safe F-CPU (T08), PROFIsafe (D4), motion (T09), diagnostics (T10). The guardrails and the eyes.
In this capping cell, the operator's HMI "Start" button is pressed but the cell won't cap. The E-stop is released. Where do you look first?
