In the era of Industrial IoT (IIoT), the standard HMI has evolved. Modern Windows Industrial Panel PCs now act as edge Gateways, bridging the gap between Operational Technology (OT) and Information Technology (IT). At Thinkbest, we specialize in high-performance computing designed for the rigors of the smart factory.

The Strategic Advantage of 4× LAN Networking

Why are 4× LAN ports becoming the industry standard? It’s about Network Segmentation:

  • LAN 1 (Management): Connects to the corporate ERP/Cloud for data reporting.

  • LAN 2 (Fieldbus): Dedicated to PLC communication (Profinet, EtherCAT).

  • LAN 3 (Vision/Sensors): High-bandwidth traffic for PoE cameras or LiDAR.

  • LAN 4 (Remote Access): A secure "Maintenance Tunnel" for remote BIOS updates and troubleshooting.

This physical isolation prevents "broadcast storms" and significantly enhances Cybersecurity on the factory floor.

Engineered for Harsh Environments

Our PCs feature a Fanless Cooling System and an IP65-rated front bezel, making them impervious to dust, oil, and moisture. Unlike consumer tablets, Thinkbest systems utilize Industrial Grade Capacitors rated for 24/7 operation in temperatures ranging from -10°C to 60°C.
