DCS/FCS比较
(1).开放性和可互操作性
开放性FCS将打破DCS大型厂家的垄断，给中小企业发展带来了平等竞争的机遇。可互操作性实现控制产品的“即插即用”功能，从而使不同厂家的工控产品可以互换和替换。
(2).分散性
*的分散性意味着系统具有较高的可靠性和灵活性，系统很容易进行重组和扩建，且易于维护。
(3).低成本
衡量一套控制系统的总体成本，不仅考虑其造价，而且应该考察系统安装调试尤其是运行维护整个生命周期内总投入。相对DCS而言，FCS开放的体系结构和OEM技术将大大缩短开发周期，降低开发成本，且*分散的分布式结构将1对1模拟信号传输方式变为1对N的数字信号传输方式，节省了模拟信号传输过程中大量的A/D、D/A转换装置，网络协议传输取代大量的信号线布线中的安装成本，可靠的性能降低了维护费用。因此从总体上来看，FCS的成本大大低于DCS的成本。
从维护角度看，FCS以其协议统一、互相兼容、合理可靠方便生产;从成本角度，更是FCS取代DCS的理由。
