To connect to an OPC DA server and read variables, developers typically implement a sequence using OpcNetApi.dll :

Type serverType = Type.GetTypeFromProgID("Kepware.KEPServerEX.V6"); object serverObj = Activator.CreateInstance(serverType); IOPCServer opcServer = (IOPCServer)serverObj; // At this point, opcnetapidll is marshaling the COM interface.

If you are working with industrial automation or developing software to communicate with PLCs (Programmable Logic Controllers), you’ve likely come across the file .

Several companies and community projects provide OPC .NET toolkits that either build upon or offer alternatives to the official opcnetapi.dll .
