Azure Industrial IoT Platform

A client and server implementation of the OPC UA specification written in Rust

Visualize and control your enterprise using OPC Unified Architecture (OPC UA) and Visual Studio.

SCADA HMI for substations and automation applications.

A portable and scalable SCADA/IIoT-I4.0/Gateway platform centered on the MongoDB database server.

A OPC UA gateway which gives you access to your OPC UA values via MQTT or GraphQL (HTTP). If you have an OPC UA server in your PLC, or a SCADA system with an OPC UA server, you can query data from there via MQTT and GraphQL (HTTP). In addition, the gateway can also log value changes from OPC UA nodes in an InfluxDB, IoTDB, Kafka, and others.
