　每个模件的I/O点数有8点和16点，很少使用32点模件。

    DCS的这种结构源于其使用领域主要在大型控制对象，19英寸标准机箱便于密集布置，较少的I/O点数则是由于对分散度的要求。PLC的大底版式机架，封闭式模件结构在管理和配置上更加灵活，单个设备的可靠性更高。因此，不少DCS也吸收了PLC在结构上的优点，采用了和PLC相似的封装结构，如I/A采用金属外壳，NETWORK-6000+采用导电塑料外壳。

    2．5、人机交互装置在早期，DCS作为一个系统，其人机交互装置是DCS厂家提供的专用装置。而PLC厂家一般不提供人机交互装置，往往由工程商自主采用通用的来完成(如ifix、intouch、组态王)。DCS集成的人机交互装置往往有着功能较专业、稳定性较好的特点，但是其价格也很高。随着PC技术的快速发展，一些通用发展很快，功能和性能逐渐超过了DCS厂家提供的专用装置。因此不少DCS厂家逐步放弃了专用的人机交互装置，转而和PLC一样也使用了通用的。DCS厂家使用通用并不是简单地拼装，而是在通用的基础上，通过合作开发，将自已多年积累的网络通讯技术、系统自诊断技术以专用软件包的形式保留和继承下来了。

例如，NT6000早期曾经使用过基于专用操作系统的T1000人机交互系统，而目前主要使用基于FIX/IFIX或INTOUCH的T3500人机交互系统。其中的LINPOLL网络通讯包是开发集成的。

    3、DCS和PLC的市场情况和发展方向

    在热工自动化领域，主厂房控制系统基本上毫无例外地使用DCS。而在辅助车间才使用PLC。其主要原因是早期的DCS系统非常昂贵，人们认为辅助车间的运行可以间断，可靠性要求不是很高，且模拟量控制要求较少，从降低成本的角度出发，往往选择PLC来构建控制系统。而锅炉、汽机和发电机的控制系统，要求长期稳定可靠地运行，信号中含有相当比例的模拟量，从系统的性能出发，人们不得不选择了昂贵的DCS。

    另外，分析一下主厂房DCS和辅助车间控制系统的市场竞争情况，我们会发现一个有趣的现象。主厂房DCS的竞争往往在不同品牌的供应商或代理商之间展开，竞争激烈,DCS的价格不断下调。而辅助车间控制系统的竞争往往在同一品牌PLC的各个工程商之间进行，门槛较低，竞争更加激烈，但是PLC的价格下调幅度却并不如DCS明显。主要原因是DCS的生产商直接参与竞争，在巨大的市场压力下，不断下调设备制造费用和工程实施费用。而PLC的生产商不直接参与竞争，各个工程商只能下调自身有限的工程费用，空间有限。从现在情况看来，DCS与高档PLC的价格差距已不明显，辅助车间仍然较多地采用PLC，是市场的惯性使然。

    随着国内电厂装机容量的不断扩大及电力系统改革的推进，对辅助车间控制的要求也不断提高，在这个大环境，DCS系统进入辅助车间控制已成为趋势。NT6000DCS因其综合的技术经济优势，已经并将继续在辅助车间控制方面发挥越来越大的作用。

    在辅助车间应用广泛的PLC也并不会就此退出热工自动化的历史舞台，前所未有的竞争压力，将会促使PLC厂商在技术上向DCS标准靠拢，在价格上作出更大的努力。市场竞争的结果，

 

        将使用户获获得更大的利益。

    4、结论

    DCS和PLC作为计算机技术和控制技术结合的产物，为火电厂热工自动化水平的提高都作出了各自的贡献。由于两者在应用上有较大的相通性，在不同的时期，其各自的技术或价格优势，都会直接影响到其市场地位。而市场的反应也会或快或慢地反映到各自的技术发展和价格调整上。从总的趋势来看，DCS和PLC在技术上的融合和促进将会是竞争的主流，而在性价比方面，你来我往地不断攀升，也将是发展的主旋律。<
