Abstract: The operating and monitoring function of new distributed control system are analyzed in this paper. Security, hardware, software and long- term trend storage are studied. The operation system of new operation station is Windows NT. DDE and OPC software are provided, so Internet can be connected into the DCS. The display mode of operation station is screen mode and window mode. The program can be written by Visual Basic or Visual C++. Because PC is used for operation station, it has high ratio of performance and price.
