OPC Data Client Development Toolkit

The OPC Data Client Development Toolkit from Software Toolbox helps developers quickly build custom x86 and x64 OPC client applications in C#, VB.NET, Python.NET, F#, managed C++, and COM languages. Simple read, write, and subscribe methods hide the OPC details, and more than 150 source code examples are included.

  • OPC UA Generic Data/Data Access, OPC UA Alarms & Conditions, and OPC UA Complex Data
  • OPC UA PubSub subscriptions over UDP, Ethernet, and MQTT with UADP and JSON message formats
  • OPC Classic Data Access 1.x/2.x/3.x, OPC Alarms & Events, and OPC XML-DA
  • OPC UA Global Discovery Client, Certificate Management Client, and multiple security policies
  • Procedural code, no-code Live Binding, Live Mapping, and Reactive Programming models
  • Browsing dialogs and controls, the Connectivity Explorer test tool, and an optional Excel Connector

The toolkit runs on Windows 10/11 and Windows Server 2016-2022, and on Linux and macOS through .NET 8 & 9. Software Toolbox, a charter member of the OPC Foundation, regularly tests OPC Data Client at OPC Foundation Interoperability Workshops. See the full OPC specification support details and supported development languages.
