Transparent socket relay for remote device access
Direct SCADA-to-device connectivity over cellular and modem links without protocol conversion.
What it is
WizIIOT Virtual Pipe Service is a platform component that bridges SCADA control systems to remote meters, field devices, and sensors connected over GPRS and modem links. It acts as a transparent bidirectional relay, forwarding all data unchanged between your primary SCADA client and remote devices, eliminating the need for custom protocol handlers. The service automatically restarts failed connections and maintains per-device visibility through dedicated logging.
Key benefits
Unmodified protocol pass-through
Data flows unchanged from SCADA to device and back, preserving your existing protocols and avoiding compatibility issues with legacy systems.
Automatic connection recovery
Timeout detection and socket restart ensure continuous availability—lost connections automatically re-establish without manual intervention.
Per-device diagnostics
Dedicated log files for each device connection provide detailed visibility into communication patterns and failure events for faster troubleshooting.
Seamless modem and cellular support
Works with GPRS, cellular modems, and PPP links—configured once in the platform database, no per-device setup required.
