Abstract

OPC is a new technology in the domain of process control.Through the research of OPC data access specification,and combining with its data access mechanism,the method of developing OPC client with COM and its specific realization process were put forward,which can bring about the access of different servers or data according to the actual demands.The example of the OPC DA server supplied by Thermo Company provs the successful actualization of reliable data transmission.
