Using OPC NET API implementation

If you want to use the OPC NET API implementation instead of the native implementation (in OpcCmd for .NET Framework), you can do it interactively as in the following example:

OpcCmd -i
aeclient --property InstanceParameters.EnableNativeClient=[Boolean]false
subscribeEvents subscribeEvents OPCLabs.KitEventServer.2

If you want to use such setting permanently, you can modify one of the OpcCmd Intrinsic Component Configuration files (JSON, INI or XML). For example, with the JSON format, put the following into the appsettings.json or appsettings.production.json file:

{
  "OpcLabs.EasyOpc.AlarmsAndEvents.EasyAEClient": {
    "InstanceParameters": {
      "EnableNativeClient": false
    }
  } 
}
