由于现场总线的以上特点，特别是其系统结构的简化，使其从设计、安装、投运到正常生产运行及检修维护，都体现出优越性。它不仅节省了硬件数量与投资，节省了安装费用，而且系统的维护开销也大大地降低。现场总线控制系统不仅精确度与可靠性高，在方便使用和维护性方面，FCS也比DCS有优势。FCS使用统一的组态方式，安装、运行、维修简便；利用智能化现场仪表，使维修预报（Predicted maintenance）成为可能；由于系统具有互操作性和互用性，用户可以自由选择不同品牌的设备达到最佳的系统集成，在设备出现故障时，可以自由选择替换的设备，保障用户的高度系统集成主动权。此外，它还具有设计简单，易于重构等特点。
传统的集散控制系统（DCS系统）具有集中监控、分散控制、操作方便的特点。但是，在实际应用中也发现DCS的结构存在一些不足之处，如控制不能做到彻底分散，危险仍然相对集中；由于系统的不开放性，不同厂家的产品不能互换、互联，限制了用户的选择范围。利用现场总线技术，开发FCS系统的目标是针对现存的DCS的某些不足，改进控制系统的结构，提高其性能和通用性。
FCS想要在实际中取代DCS，既要具备DCS所具有的功能，又要能克服DCS的缺点。FCS由于采用了现场总线技术，在开放性、控制分散等方面优于传统DCS。但是由于它是一种新技术，目前连标准本身都还没有制定统一，因此FCS与成熟的DCS相比，还存在下列的一些欠缺。
