系统与dcs系统的结构差异不大，只是在功能的着重点上的不同，DCS着重于闭环控制及数据处理。PLC着重于逻辑控制及开关量的控制，也可实现模拟量控制。

    DCS或PLC系统的关键是通信。也可以说数据公路是分散控制系统DCS及PLC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，数据公路自身的设计就决定了总体的灵活性和安全性。数据公路的媒体可以是：一对绞线、同轴电缆或光纤电缆。

    DCS的特点

    （1）控制功能强。可实现复杂的控制规律，如串级、前馈、解耦、自适应、最优和非线性控制等。也可实现顺序控制。

    （2）系统可靠性高。

    （3）采用CRT操作站有良好的人机界面。

    （4）软硬件采用模块化积木式结构。

    （5）系统容易开发。

    （6）用组态软件，编程简单，操作方便。

    （7）有良好的性价比。

    通过数据公路的设计参数，基本上可以了解一个特定DCS或PLC系统的相对优点与弱点。

    （1）系统能处理多少I/O信息。

    （2）系统能处理多少与控制有关的控制回路的信息。

    （3）能适应多少用户和装置（CRT、控制站等）。

    （4）传输数据的完整性是怎样彻底检查的。

    （5）数据公路的最大允许长度是多少。

    （6）数据公路能支持多少支路。

    （7）数据公路是否能支持由其它制造厂生产的硬件（可编程序控制器、计算机、数据记录装置等）。为保证通信的完整，大部分DCS或PLC厂家都能提供冗余数据公路。

    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接收与发送。

    目前在DCS和PLC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。

    PLC与DCS的前景

    大家都知道FCS是由PLC或DCS发展而来，现在FCS系统被广泛的应用，那么，PLC与DCS前景又将如何。

    PLC于20世纪60年代末期在美国首先出现，目的是用来取代继电器，执行逻辑、计时、计数等顺序控制功能，建立柔性程序控制系统。1976年正式命名，并给予定义：PLC（ProgrammablelogicController）是一种数字控制专用电子计算机，它使用了可编程序存储器储存指令，执行诸如逻辑、顺序、计时、计数与演算等功能，并通过模拟和数字输入、输出等组件，控制各种机械或工作程序。经过30多年的发展，PLC已十分成熟与完善，并具有强大的运算、处理和数据传输功能。并定义为可编程控制器（ProgrammableController　PLC）。PLC在FCS系统中的地位似乎已被确定并无多少争论。参见图3：IEC推荐的现场总线控制系统体系结构。PLC作为一个站挂在高速总线上。充分发挥PLC在处理开关量方面的优势。另外，电厂辅助车间，例如水处理车间、循环水车间、除灰除渣车间、输煤车间等，这些车间的工艺过程多以顺序控制为主。PLC对于顺序控制有其独特的优势。辅助车间的控制系统应以遵循现场总线通讯协议的PLC或能与FCS进行通讯交换信息的PLC为优选对象。

    现场总线的应用是工业过程控制发展的主流之一。可以说FCS的发展应用是自动化领域一场革命。采用现场总线技术构造低成本现场总线控制系统，促进现场仪表的智能化、控制功能分散化、控制系统开放化，符合工业控制系统技术发展趋势。
