TIA Portal Beginner: Latching & Interlocks (Emergency Stop)

Welcome back to the Beginner PLC Mega-Project! In Episode 4, we learn latching circuits and safety interlocks — two essential concepts in industrial PLC programming. 🔹 What you’ll learn in this video: • Why latching logic is needed in automation • How to build a latch rung in Siemens TIA Portal • Adding an Emergency Stop (Estop) interlock for safety • Testing Start, Stop, and Estop in PLCSIM simulation • Industry context: why Estop must always override everything ⚙️ Hands-On Project: We’ll modify our conveyor motor rung to include: • Start button • Motor coil self-latch • Stop button • Estop button By the end of this lesson, you’ll have a realistic motor control circuit just like the ones used in factories. 👉 Subscribe to @Ohmmeter_AG and follow the complete Beginner PLC Mega-Project — from basic Ladder Logic all the way to HMI design and full automation systems.
