计算机及网络技术与控制系统的发展有着紧密的联系。最早在50年代中后期，计算机就已经被应用到控制系统中。60年代初，出现了由计算机完全替代模拟控制的控制系统，被称为直接数字控制（DirectDigitalControl,DDC）。70年代中期，随着微处理器的出现，计算机控制系统进入一个新的快速发展的时期，1975年世界上第一套以微处理为基础的分散式计算机控制系统问世，它以多台微处理器共同分散控制，并通过数据通信网络实现集中管理，被称为集散控制系统
计算机控制系统也是经历了集中控制、分层控制、基于现场总线的网络控制等几个发展阶段，它们的发展过程是非常相似的。
随着企业信息网络的深入应用与日臻完善，现场控制信息进入信息网络实现实时监控是必然的趋势。为提高企业的社会效益和经济效益，许多企业都在尽力建立全方位的管理信息系统，它必须包括生产现
