摘要： 在解决分散控制系统(DCS)中多平台的数据访问和集成问题时，必须为每个不同的平台开发一个相应的数据访问接口和服务器。在研究FDT技术的基础上，提出一个基于FDT技术的OPC跨平台数据访问模型，利用该模型解决了在DCS系统下数据访问依赖于设备的现场总线类型、厂商和设备特点的问题。

Abstract: The problems that solving multi-platforms’ integration and data access of Distributed Control System(DCS) control system which needs to implement a corresponding data interface and server for each different data platform. On the base of researching the FDT technology, this paper puts forward a development model of OPC data access based on Field Device Tool(FDT) technology which can cross many platforms. In this way, the model solves the problem that data access is not independent of fieldbus protocols, device manufacture and device type in the DCS system.
