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，它必须包括生产现场的实时数据信息，以确保实时掌握生产过程的运行状态，使企业管理决策科学化，达到生产、经营、管理的化状态。信息一控制一体化将为实现企业综合自动化CIPA（computerintegratedplantautomation）和企业信息化创造有利条件。
企业信息网络与控制系统在体系结构发展过程上的相似性不是偶然的。在计算机控制系统的发展过程中，每一种结构的控制系统的出现总是滞后于相应计算机技术的发展。实际上，大多数情况下，正是在计算机领域一种新技术出现以后，人们才开始研究如何将这种新技术应用于控制领域。鉴于两种应用环境的差异，其中的技术细节作了适当修改和补充，但关键技术的原理及实现上，它们有许多共同的地方。正是由于二者在发展过程中的这种关系，使得实现信息一控制一体化成为可能。
