Скачать или смотреть Real Time Heat Exchanger Digital Twin — Closed Loop PLC Control (Micro850 + Isaac Sim)

This video demonstrates a real-time closed-loop digital twin architecture applied to a heat exchanger process.

This is not an animation and not a scripted simulation.

A real PLC executes deterministic control logic, while a simulated physical process runs in NVIDIA Isaac Sim.
The PLC sends commands to the digital twin, the digital twin simulates the physics in real time, and virtual sensors feed physical feedback back to the PLC.
The PLC continuously reacts to that feedback — exactly as it would in a real industrial system.

🔧 What’s demonstrated in this video
• Real-time closed-loop control between PLC and digital twin
• Deterministic control logic implemented with User-Defined Function Blocks (UDFB)
• Reusable valve blocks on both PLC and digital twin sides
• Simulated heat exchanger process with temperature evolution
• Virtual temperature sensors generated by the simulation
• Bidirectional communication using a Python PyLogix I/O bridge
• Object-Oriented Industrial Digital Twin (OOIDT) principles applied in practice

🧠 Key architectural principles
• The PLC is the master of all real-time decisions
• The digital twin does not contain control logic
• Physics is simulated outside the PLC and exposed through virtual sensors
• Control logic is written once and reused at scale
• The same architecture applies to simulation and real plants
This approach allows scalable, credible, and industrial-grade digital twins — not demos.
