Edge XRT

A software foundry that helps drive IoT innovation, global adoption, market velocity and scale at the edge


Edge XRT is a lightweight IoT Edge Computing platform designed specifically for Time-Critical and Resource-Constrained embedded Industrial IoT systems.  Edge XRT is a fully integrated and commercially-licensed extension of the Linux Foundation’s EdgeX Foundry platform that enables the EdgeX ecosystem to support the full spectrum of secure hard and soft real-time Edge Computing requirements.


Edge XRT provides a powerful IoT Edge Computing platform supporting key requirements such as dynamic edge data processing and the integration of multiple different southbound OT and northbound IT/Cloud endpoints. Edge XRT delivers these capabilities, however, whilst also supporting the following key non-functional properties:

  • Small memory footprint (e.g. less than 100 KB)
  • Ultra-low latency data processing (e.g. less than 100 microseconds)
  • Predictable and deterministic real-time execution
  • Legacy hardware and/or operating systems


  • Loosely-coupled microservices architecture deployed in a lightweight single address space microcontainer
  • Real-Time Core processing engine allowing for the pluggable deployment of user components and analytics at run-time
  • Implemented in the C programming language so is extremely lightweight, fast and portable
  • Integration with multiple OT device endpoints including ModbusBACnetMQTT, OPC UA, BLE, Zigbee, EtherCAT, PROFINET and many more
  • Integration with multiple IT/Cloud endpoints including AWS, Google Cloud IOT, Microsoft Azure and many more
  • Integration to EdgeX Foundry and Edge Xpert for more comprehensive Edge IoT processing


Edge XRT is targeted at embedded and real-time controllers used in process automation and industrial control applications where low latency and deterministic processing is a critical requirement. Its use spans different vertical domains including factory automation, oil and gas, utilities and smart energy.
