Abstract
OPC has made it to improve the development of control and monitoring software. But it is difficult to understand COM/DCOM model that is a base technology of OPC and complex communication setting between OPC Server and OPC Client. Therefore, in this paper, we design and implement ActiveX based components that are enable to solve these problems. Implemented components provide a method for simple communication between OPC Server and OPC Client and a GUI environment for easy and fast setting of communication information. Also, they provide the architecture for efficient management of OPC Server's data. By using implemented component, easy development and efficient maintenance of OPC Client can be supported.
