Intrinsic component configuration examples

Set the default URL of the OPC UA Global Discovery Server (GDS)

In order to set the default URL of the OPC UA Global Discovery Server (GDS) used by QuickOPC global discovery operations, you can use the following appsettings.json file:

{
  "OpcLabs.EasyOpc.UA.EasyUAClient": {
    "InstanceParameters": {
      "GdsEndpointDescriptor": {
        "UrlString": "opc.tcp://opcua.demo-this.com:58810/GlobalDiscoveryServer"
      }
    }
  } 
}

Use NET API implementation of OPC Data Access client

{
  "OpcLabs.EasyOpc.DataAccess.EasyDAClient": {
    "InstanceParameters": {
      "EnableNativeClient": false,
      "EnableNetApiClient": true
    }
  } 
}

If your project involves user interface, it needs to be configured too:

{
  "OpcLabs.EasyOpc.DataAccess.EasyDAClient": {
    "InstanceParameters": {
      "EnableNativeClient": false,
      "EnableNetApiClient": true
    }
  },

  "OpcLabs.EasyOpc.DataAccess.Forms.Browsing.DADialog": {
    "ClientSelector": {
      "InstanceParameters": {
        "EnableNativeClient": false,
        "EnableNetApiClient": true
      }
    }
  }
}
