Application research on OPC server based on multi-fieldbus

As a distributed open system in manufacturing and process control environment, fieldbus aims to provide an international standard in this field. In order to satisfy the requirement of data transfer in industrial control, the interface between fieldbus and the program also need to pursue a standard. OPC technology is introduced to satisfy the requirement of efficient data transfer. It develops an open and interoperable interface standard between applications and fieldbus. Making use of fieldbus and OPC advantages, a system model is researched, which can simplify the data exchanging and sharing across the industrial information system, and has a far-reaching meaning for the enterprise integrated automation.
