以NT6000的ELIN网为例，虽然也是基于工业以太网的，但其应用层协议是积累了近30年的无主令牌LIN网协议，在1M的OLIN，2.5M和20M的ARCNET上都有长期成功的应用。ELIN网上，各站平等，不存在主要管理站。而且数据通讯是以模块为单位的结构化数据，数据管理能力非数据表方式可比。

    以PID模块为例，其中的基本数据有PV、SP、OP，采用数据表的传输方式，你必须先定义PV、SP、OP的数据地址为01、02、03，其它的站也以数据表的方式接收数据，但是01是什么数据？02是什么数据？必须通过数据定义表才能还原。数据表的管理方式烦琐易错,一个大型系统的上万点数据采用这个方式,平铺在数据表中进行管理，是非常可怕的。而NT6000DCS以模块为单位的结构化管理，将一个PID作为一个模块进行处理，要访问其PV值，首先访问其模块，以PID.PV的形式来管理。这就将所有平铺的数据，分类归属集中到一个个小盒子中，按模块.分量的方式进行管理，管理的效率大大提高。PLC数据通讯交换的问题，主要源于PLC长期以来做为一个独立装置在发展，没有系统概念；而且主要应用在小型控制系统中，问题暴露得并不明显，所以发展较慢。目前也有一些大型PLC在这个方面有所提高，但是要达到DCS的水平还需要一个相当长的过程。

    2．3、组态维护功能组态维护功能包括逻辑组态、下载修改、运行调试、远程诊断等。

    早期，PLC以梯形图为主，DCS以模块功能图为主。经过多年的发展，国际电工委员会通过IEC1131-3标准规定了五种编程语言,目前主流的DCS和PLC都表示符合这个标准，支持其中的几种或全部编程语言。从开发效率和程序可读性来考虑，模块功能图和顺序功能图越来越成为主要的编程方式，梯形逻辑和结构化文本成为了自定义模块的开发工具。大型PLC在组态方式上越来越像DCS，差距在逐渐缩小，而小型PLC仍然以梯形图为主。

    DCS经过多年的发展，积累了大量的高级算法模块。例如NT6000具有的设备级模块，在一个模块中集中完成了面向设备的基本控制和故障报警功能，在网络通讯中也已此模块为单位进行传递，大大提高了软件开发的效率。一个设备极模块相当于0.5K的梯形图逻辑量，PLC要完成同样的功能，就要烦琐得多了。

    在下载修改、运行调试、远程诊断方面，PLC缺乏解决方案。而DCS从一设计之初就是从系统需要的角度出发的，有着多年积累的完善的解决方案。以NT6000DCS为例，系统既可以在线修改控制策略，也可以在线下载控制策略，修改和下载过程中，对系统的正常运行没有影响。NT6000DCS有完善的虚拟DCS功能，不但可以用于组态逻辑的验证，而且能够构建成完整的虚拟DCS与模型相连，完成系统的仿真调试。NT6000DCS具有完善的安全措施，提供基于广域网的远程调试方案。

    2．4、硬件封装结构

    PLC一般为大底版式机架，封闭式I/O模件，封闭式结构有利与提高I/O模件的可靠性，抗射频、抗静电、抗损伤。PLC模件的I/O点数有8点、16点、32点。

    DCS大部分为19英寸标准机箱加插件式I/O模件，I/O模件为裸露式结构。
