OPC Unified Architecture .NET Standard.zip
(10.48 MB, 售价: 10 E币)
Overview
This OPC UA reference implementation is targeting .NET Standard .
.Net Standard allows you develop apps that run on all common platforms available today, including Linux, iOS, Android (via Xamarin) and Windows 7/8/8.1/10 (including embedded/IoT editions) without requiring platform-specific modifications.
One of the reference implementations inside this project has been certified for compliance through an OPC Foundation Certification Test Lab to prove its high quality. Fixes and enhancements since the certification process have been tested and verified for compliance using the Compliance Test Tool (CTT) V1.03.
Furthermore, cloud applications and services (such as ASP.Net, DNX, Azure Websites, Azure Webjobs, Azure Nano Server and Azure Service Fabric) are also supported.
For more information and license terms, see here.

OPC UA Reference Server has been certified for compliance through an OPC Foundation Certification Test Lab. Fixes and enhancements since the certification process have been tested and verified for compliance using the Compliance Test Tool (CTT) Version 1.03.340.380.
An official OPC UA Nuget package of the core, client, server and configuration libraries is available for integration in .Net projects.
The Core UA stack and SDK has been tested with Mono 5.4 to add support for the Xamarin Client and the Mono console application samples.
Getting Started
All the tools you need for .Net Standard come with the .Net Core tools. See here for what you need.
Self signed certificates for the sample applications
All required application certificates for OPC UA are created at the first start of each application in a directory or OS-level certificate store and remain in use until deleted from the store.
Windows .Net applications
By default the self signed certificates are stored in a X509Store called CurrentUser\UA_MachineDefault. The certificates can be viewed or deleted with the Windows Certificate Management Console (certmgr.msc). The trusted, issuer and rejected stores remain in a folder called OPC Foundation\CertificateStores with a root folder which is specified by the SpecialFolder variable %CommonApplicationData%. On Windows 7/8/8.1/10 this is usually the invisible folder C:\ProgramData.
Note: Since the sample applications in the UA-.Net repository use the same storage and application names as UA-.NetStandard, but create only certificates with hostname localhost, it is recommended to delete all existing certificates in MachineDefault to recreate proper certificates for all sample applications when moving to the UA-.NetStandard repository.
Windows UWP applications
By default the self signed certificates are stored in a X509Store called CurrentUser\UA_MachineDefault. The certificates can be viewed or deleted with the Windows Certificate Management Console (certmgr.msc).
The trusted, issuer and rejected stores remain in a folder called OPC Foundation\CertificateStores in the LocalState folder of the installed universal windows package. Deleting the application state also deletes the certificate stores.
.Net Standard Console applications on Windows, Linux, iOS etc.
The self signed certificates are stored in a folder called OPC Foundation/CertificateStores/MachineDefault with a root folder which is specified by the SpecialFolder variable %LocalApplicationData% or in a X509Store called CurrentUser\My, depending on the configuration. For best cross platform support the personal store CurrentUser\My was chosen to support all platforms with the same configuration. Some platforms, like macOS, do not support arbitrary certificate stores.
The trusted, issuer and rejected stores remain in a shared folder called OPC Foundation\CertificateStores with a root folder specified by the SpecialFolder variable %LocalApplicationData%. Depending on the target platform, this folder maps to a hidden locations under the user home directory.
Local Discovery Server
By default all sample applications are configured to register with a Local Discovery Server (LDS). A reference implementation of a LDS for Windows can be downloaded here. To setup trust with the LDS the certificates need to be exchanged or registration will fail.
How to build and run the samples in Visual Studio on Windows
Open the UA-NetStandard.sln solution file using Visual Studio 2017.
Choose a project in the Solution Explorer and set it with a right click as Startup Project.
Hit F5 to build and execute the sample.
How to build and run the console samples on Windows, Linux and iOS
This section describes how to run the NetCoreConsoleClient and NetCoreConsoleServer sample applications.
Please follow instructions in this article to setup the dotnet command line environment for your platform. As of today .Net Standard 2.0 is required.
Prerequisites
Once the dotnet command is available, navigate to the root folder in your local copy of the repository and execute dotnet restore UA-NetStandard.sln. This command calls into NuGet to restore the tree of dependencies.
Start the server
Open a command prompt.
Navigate to the folder SampleApplications/Samples/NetCoreConsoleServer.
To run the server sample type dotnet run --project NetCoreConsoleServer.csproj -a.
The server is now running and waiting for connections.
The -a flag allows to auto accept unknown certificates and should only be used to simplify testing.
Start the client
Open a command prompt
Navigate to the folder SampleApplications/Samples/NetCoreConsoleClient.
To run the sample type dotnet run --project NetCoreConsoleClient.csproj -a to connect to the OPC UA console sample server running on the same host.
The -a flag allows to auto accept unknown certificates and should only be used to simplify testing.
To connect to another OPC UA server specify the server as first argument and type e.g. dotnet run --project NetCoreConsoleClient.csproj -a opc.tcp://myserver:51210/UA/SampleServer.
If not using the -a auto accept option, on first connection, or after certificates were renewed, the server may have refused the client certificate. Check the server and client folder %LocalApplicationData%/OPC Foundation/CertificateStores/RejectedCertificates for rejected certificates. To approve a certificate copy it to the %LocalApplicationData%/OPC Foundation/CertificateStores/UA Applications folder.
Retry step 3 to connect using a secure connection.
How to build and run the OPC UA COM Server Wrapper
Please refer to the OPC Foundation UA .Net Standard Library COM Server Wrapper for a detailed description how to run the OPC COM wrapper.
How to build and run the OPC UA Aggregation Client and Server
Please refer to the OPC Foundation UA .Net Standard Library Aggregation Client and Server for a detailed description how to run the aggregation client and server.
How to build and run the OPC UA Reference Server with UACTT
Please refer to the OPC Foundation UA .Net Standard Library Reference Server for a detailed description how to run the reference server against the UACTT.
How to build and run the OPC UA Xamarin Client
Please refer to the OPC UA Xamarin Client for a detailed description how to run the UA Xamarin Client on UWP, Android and iOS.
What happened to the OPC UA Web Telemetry sample?
The web telemetry sample was removed as there is a much more complete (and better looking!) solution now available here. You can try this new solution, called "Connected Factory", out here.
