描述

DSDX452

1996年由于DEC公司被Compaq公司兼并，2000年Compaq公司又被HP兼并。Network-90和INFI 90系统买不到合适的机器作为操作站主机，Bailey公司采用PC机作为操作站主机，它就是ConductorNT操作站，但它没有继承这个优点，而是另起炉灶，作图必须一笔一笔地画。有一个电厂，要将INFI 90系统的原OIS25操作站更换为ConductorNT操作站，一共有40幅流程图，200条趋势曲线，140幅文本画面，完成该任务需要18个人*月。如能把老操作站的图形用软件转换，只要几十秒钟，转换完成以后，可能还会有一些不太符合要求的地方，在这个基础上进行修改，时间就会节省很多，大约需要一个人*月。由此可见，采用这种标准化的方式操作，工作量减少是巨大的。
需要制订标准的另外一个原因是操作站软件呈多元化趋势，有像iFIX、InTouch、组态王这种类型的，还有SL-GSM这样的软件，它已经用上XML的编程方法。还有，现在数据库的功能在进一步扩大，如神经元网络的算法已经包括在数据库中；还有OPC之间的数据交换等，都要求有一个编程标准。编程标准靠一个公司是无法制订完成的，需要国际社会共同努力完成。

七十年代以前，控制系统中采用模拟量对传输及控制信号进行转换、传递，其精度差、受干扰信号影响大，因而整个控制系统的控制效果及系统稳定性都很差。七十年代末，随着大规模集成电路的出现，微处理器技术得到很大发展。微处理器功能强、体积小、可靠性高、通过适当的接口电路用于控制系统，控制效果得到提高；但是尽管如此，还是属于集中式控制系统。随着过程控制技术、自动化仪表技术和计算机网络技术的成熟和发展，控制领域又发生了一次技术变革。这次变革使传统的控制系统（如集散控制系统）无论在结构上还是在性能上都发生了巨大的飞跃，这次变革的基础就是现场总线技术的产生。
