DCS经过多年的发展，积累了大量的高级算法模块。例如NETWORK6000+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NETWORK6000+DCS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。NETWORK6000+DCS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。NETWORK6000+DCS具有完善的安全措施，提供基于广域网的远程调试方案。
在网络方面,DCS网络是整个系统的中枢神经，和利时公司的MACS系统中的系统网采用的是双冗余的100Mbps的工业以太网，采用的标准协议TCP/IP。它是安全可靠双冗余的高速通讯网络，系统的拓展性与开放性更好.而PLC因为基本上都为个体工作，其在与别的PLC或上位机进行通讯时，所采用的网络形式基本都是单网结构，网络协议也经常与标准不符。在网络安全上，PLC没有很好的保护措施。我们采用电源,CPU,网络双冗余.
