What is I3X?

I3X (Industrial Information Interface eXchange) is a standardized API specification for accessing manufacturing and industrial data. It provides a unified interface regardless of the underlying platformβ€”whether OPC UA, MQTT, historians, or cloud services.

i3X Explorer makes it easy to connect to any I3X-compliant server and explore your industrial data without writing code.

  • Unified API across different industrial platforms
  • Hierarchical data model with namespaces and types
  • Real-time subscriptions with quality indicators
  • Historical data access
  • Relationship-aware data navigation
