OPC Wizard

• NuGet package: OpcLabs.OpcWizard

OPC Wizard is a suite of OPC Server development components for .NET. These components are for OPC Unified Architecture (Client-Server) specification.

Note: For OPC client or subscriber development, see QuickOPC.

OPC Wizard is a commercially licensed product. Without a license key, it runs in a trial mode. The trial provides valid data to from the server for 30 minutes; after that period, the component (your app) needs to be re-started, and so on. You must also comply with licensing terms for 3rd-party material redistributed with QuickOPC. For details, see the documentation.

Remember that NuGet packages are primarily a tool for resolving build-time dependencies. The amount of functionality that you get through OPC Wizard NuGet packages is smaller than what OPC Wizard can actually do for you. If you want a full coverage of the features, you would be better off downloading the Setup program from OPC Labs Web site. Further below you will find a list of differences between the two distribution forms.

OPC Wizard requires .NET Framework 4.7.2 or .NET 8.0 as a minimum. Under .NET 8.0+, it is supported on Microsoft Windows.

PLEASE DO NOT USE PRE-RELEASE PACKAGES UNLESS INSTRUCTED TO DO SO.
