Beyond OOP:
the power tools.
You've got objects down. Next come the everyday workhorses that make a real TwinCAT 3 machine tick: timers, state machines, pointers, bullet-proof error handling, and how the IEC languages relate to each other. There are five chapters, each with a hands-on toy and no fluff.
Timing & flow
⏳ TON / TOF / TP timers · 🧺 CASE state machines that tame any sequence.
Power tools
🗄️ Pointers & REFERENCE · 🧯 error handling patterns · 🗣️ LD vs ST vs FBD.
Best after Parts 1–3 (arrays + OOP), though each chapter stands on its own.
