An OPC Client's development environment is transparent to KEPServerEX. The client application may be developed in any language and used with KEPServerEX as long as it utilizes one of KEPServerEX's supported interfaces (such as OPC DA, OPC UA, OPC AE, SuiteLink, NIO, Oracle, and so forth). For information on developing an OPC DA or OPC UA Client application using C# or Visual Basic .Net, refer to the ClientAce Help File.
