控制类产品名目繁多，各家叫法不一。通常使用的控制类产品包括DCS、PLC两大类。我们又将DCS的概念拓展到FCS。DCS（Distributed Contorl System）,集散控制系统，又称分布式控制系统，是相对于集中式控制系统而言的一种计算机控制系统，它是在集中式控制系统的基础上发展、演变而来的。FCS（FieldBus Contorl Syestem），现场总线控制系统。它是用现场总线这一开放的、具有互操作性的网络将现场各个控制器和仪表及仪表设备互联，构成现场总线控制系统，同时控制功能彻底下放到现场，降低了安装成本和维修费用。PLC（Program Logic Control ）,可编程逻辑控制器。
FCS是由DCS与PLC发展而来，不仅具备DCS与PLC的特点，而且跨出了革命性的一步。目前新型的DCS与新型的PLC，都有向对方靠拢的趋势。新型的DCS已有很强的顺序控制功能;而新型的PLC，在处理闭环控制方面也不差，并且两者都能组成大型网络，DCS与PLC的适用范围，已有很大的交叉。
DCS系统的关键是通信。也可以说数据总线是分散控制系统DCS的脊柱。由于它的任务是为系统所有部件之间提供通信网络，因此，数据总线自身的设计就决定了总体的灵活性和安全性。数据总线的媒体可以是:一对绞线、同轴电缆或光纤电缆。通过数据总线的设计参数，基本上可以了解一个特定DCS系统的相对优点与弱点。
为保证通信的完整，大部分DCS厂家都能提供冗余数据总线。为了保证系统的安全性，使用了复杂的通信规约和检错技术。所谓通信规约就是一组规则，用以保证所传输的数据被接收，并且被理解得和发送的数据一样。目前在DCS系统中一般使用两类通信手段，即同步的和异步的，同步通信依靠一个时钟信号来调节数据的传输和接收，异步网络采用没有时钟的报告系统。
