OPC-Proxy Core Library

The OPC-Proxy allows to build and deploy a customized IoT gateway to connect any OPC server with your network of microservices or cloud. This is the core library of the OPC-Proxy project where all heavy lifting is performed. This library is suitable for monitoring and control of devices, we focused on defining a protocol for bidirectional communication exposing the user to a simple API, so that one can read, but also write values to the OPC server without knowing details about OPC.

Features:

• Suitable for monitoring and controlling devices.
• Simple API.
• Reliable OPC client build with the OPC-foundation standard library.
• Load nodes from an XML file (Nodeset XML spec) or simply browsing the server
• Powerful Nodes loading selection options
• Modular design with external connectors that can be added, extended and customized.
• Supported connectors: gRPC, Kafka, InfluxDB.
• Written in C#.

Documentation

You can find all details about the library and the OPC-Proxy Project at opc-proxy.readthedocs.io.

Use the package

Add it to your project from the nuget repository

dotnet add package opcProxy.core

Use it in your project:

using OpcProxyCore;

namespace myproxy
{
    class Program
    {

        static int Main(string[] args)
        {
            // instantiaing the manager,
            // this will load configuration from file or args
            serviceManager manager = new serviceManager(args);

	    // Add Connectors
	    // manager.addConnector(_my_nice_connector_);

            // This runs the OPC-Proxy manager with all core
            // functionalities: connects to server, monitor items...
            manager.run();
            return 0;
        }

    }
}
