文中分析研究了新型集散控制系统CS—3000操作站的监视与控制功能。对其安全性、硬件、软件和长时间趋势存储等功能进行了研究。新型集散控制系统操作站具有Windows NT 操作系统。可提供DDE和OPC软件包,为工厂网络提供直接数据服务。操作站显示方式有全屏模式和窗口模式。能够使用Visual Basic 或Visual C++,为用户创建自己的程序。由于使用了PC机,新型操作站具有较高的性能价格比。 关键词:操作监视;趋势存储;安全性; 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.
