OPC Server Software Design in DCS

摘要

In order to meet the application of OPC for process control, a set of OPC server interface software is designed with OPC specification in this paper. This software organizes the device data as OPC standard data for other equipments which also support the OPC standard, and it successfully solves the communication between different equipment manufacturers. The software is applied in the Distributed Control System (DCS), so as to realize the data exchange between the management configuration software and the control device, which enhance the compatibility and interoperability of the system.
