810-810202-013工控应用PLC控制系统电源连接处理模块PLC与DCS术语“分布式控制系统”是指I/O传感器和“本地”控制器的分布，而这些传感器和控制器实际上从未来自使用DCS术语的供应商。

相反，传感器主要通过通过许多配线柜和接线盒回到CENTRAL处理器的长线路。此外，分布式模型是将数据处理从控制室向外转移到控制点。这在很大程度上也是用词不当。

Bailey、FoxB、Honeywell和其他公司都曾一度声称提供DCS，但他们实际上销售了更多的CCS或集中式控制。根据处理器的布局和位置，PLC可以是DCS或CCS。PLC相对于DCS的真正好处是能够准确地购买所需的I/O数量并将其放在您想要的位置。这就是真正的DCS，I/O和CPU/控制器可以真正分布式。通常PLC有几个垂直和水平的通信层，而大多数所谓的DCS只是宽范围的单源。

PLC HMI应用程序的是显而易见的，DCS IO的大约是PLC IO的两倍，请记住，有了DCS IO，您可以拥有现成的冗余，但您会为其留出额外的空间，对于PLC，如果你想要冗余，它与大多数标准PLC（如Modicon Quantum或Micro或AB PLC-5）的关系会更密切，除非你选择更昂贵的类型，如Triconex或FSC系统，否则就没有真正的。

810-810202-013 Industrial Control applications PLC control system Power connection Processing Module PLC and DCS The term "distributed control system" refers to the distribution of I/O sensors and "local" controllers that never actually come from a supplier that uses the DCS term.

Instead, the sensors are primarily routed back to the CENTRAL processor through a number of distribution cabinets and junction boxes. In addition, the distributed model is to move data processing outward from the control room to the control point. This, too, is largely a misnomer.

Bailey, FoxB, Honeywell, and others all claimed to offer DCS at one point, but they actually sold more CCS or centralized control. Depending on the layout and location of the processor, the PLC can be either DCS or CCS. The real benefit of PLCS over DCS is the ability to buy exactly the amount of I/O you need and put it where you want it. This is true DCS, where I/O and CPU/ controller can be truly distributed. PLCS typically have several vertical and horizontal communication layers, while most so-called DCS are just a single source with a wide range.

PLC HMI applications are obvious, DCS IO is about twice as large as PLC IO, remember that with DCS IO you can have redundancy readily available, but you will leave extra space for it, for PLCS, if you want redundancy, It will be more closely related to most standard PLCS, such as Modicon Quantum or Micro or AB PLC-5, unless you choose a more expensive type, such as Triconex or FSC system, there is no real one.
