新世纪现场控制系统体系结构的发展趋势

THE DEVELOPING TREND OF LOCALE CONTROL SYSTEM STRUCTURE IN NEW CENTURY

在信息技术飞速发展的今天 ,IEC现场总线国际标准还是一个过渡标准 ,其发展的方向只能是向社会的主流网络技术靠拢 ,由部分的开放到全部的开放。具体讲 ,近期较有前途的是让计算机主流网络技术和设备直接走向控制的现场 ,至少向下延伸至设备级。实现低技术壁垒和低成本 ,是新的现场总线标准走向普及。

On today of repid development in information technology,the international standard of IEC fieldbus is just the same one transition standard.It is can but close to social mainstream network technology that of his develop heading,from segmental open to all open.It is compared with outlook recently that let mainstream computer network technology and equipment directness used in the locale of control,At least down extend to equipment level. Both realize low technology rampart and low cost are the only way of new fieldbus standard made for popularization and successful.
