Industrial Applications

1. Secure Site-to-Site PLC and SCADA Integration

Utilizes the 5 hardware-accelerated IPSec VPN tunnels with AES encryption to bridge remote PLC controllers or local SCADA systems at decentralized sub-stations back to a centralized industrial control room over a standard broadband line.

Problem Solved

Eliminates the exorbitant cost of dedicated lease-line telemetries while maintaining strict, encrypted data integrity and security for critical automation controls.

2. Local Telemetry Backup via Shared Network Storage

Leverages the multi-functional USB 2.0 port mapped as a localized FTP or Samba server to allow local network-enabled data loggers or sensors to stream and archive backup datasets onto a connected industrial USB drive.

Problem Solved

Provides an inexpensive, localized redundant database in the event of primary fiber network disconnects, safeguarding environmental or performance metrics.

3. Isolated Wi-Fi Test-Bench for Factory Commissioning

Employs the isolated Guest Network and IP-based Quality of Service (QoS) controls to create a secure, bandwidth-throttled wireless sandbox specifically for newly built or untrusted machines undergoing factory testing.

Problem Solved

Prevents unauthorized network communication from unfinished machine firmware to the enterprise backplane, eliminating the risk of virus spread or network floods during commissioning.
