The official OPC Foundation reference implementation of the OPC Unified Architecture (OPC UA) protocol for .NET, providing client, server, PubSub, and GDS libraries. It is a certified, cross-platform industrial communication stack used in manufacturing, energy, and IoT systems.
Use cases
- build an OPC UA client to read industrial sensor data
- implement an OPC UA server for a PLC or device
- exchange telemetry between factory equipment and cloud via PubSub
- integrate manufacturing systems with ISA-95 or AAS companion specs
- connect industrial IoT gateways to SCADA systems
- add secure machine-to-machine communication in .NET
When to choose
- you need a certified, standards-compliant OPC UA stack in .NET
- you need cross-platform support including .NET 8/9/10 and AOT
- you require coverage of OPC UA companion specifications like Alarms, Historical Access, or Robotics
- you want the official reference implementation maintained by the OPC Foundation
When to avoid
- you need OPC UA in a non-.NET language like Java, Python, or C++
- you only need lightweight MQTT or Modbus communication without OPC UA semantics
- you target platforms unsupported by .NET Standard 2.1 or later
